The average speed of a volleyball serve is 58 miles per hour. Natalie practiced a new technique to improve her serving speed. Her coach recorded the speed of 41 random serves during practice and found that her average speed using the new technique was 59 miles per hour, with a standard deviation of 2.7 miles per hour.

Part A: State the correct hypotheses if Natalie is trying to prove the new technique is an improvement over the old technique. (2 points)

Part B: Identify the correct test and check the appropriate conditions. (4 points) .

Part C: Carry out the test and determine if there is sufficient evidence at the 0.05 level that Natalie's technique has improved her serve speed. (4 points)

Answers

Part A:
Null hypothesis: The new technique does not improve Natalie's volleyball serve speed.
Alternative hypothesis: The new technique improves Natalie's volleyball serve speed.

Part B:
The appropriate test for this situation is a one-sample t-test. We need to check the following conditions:
1. Random sample: We are told that the coach recorded the speed of 41 random serves, so this condition is met.
2. Normality: We assume that the distribution of serve speeds is approximately normal. We can check this condition by creating a histogram or a normal probability plot of the sample data. If the data is not normal, we can use the central limit theorem since the sample size is large enough (n > 30).
3. Independence: We assume that each serve speed is independent of the others.

Part C:
Using a one-sample t-test with a significance level of 0.05, we need to calculate the test statistic and compare it to the critical value from the t-distribution with 40 degrees of freedom (since n - 1 = 40).

t = (59 - 58) / (2.7 / sqrt(41)) = 3.23

The critical value for a two-tailed test with alpha = 0.05 and 40 degrees of freedom is approximately ±2.021.

Since our test statistic (3.23) is greater than the critical value (2.021), we reject the null hypothesis. We can conclude that there is sufficient evidence at the 0.05 level to suggest that Natalie's new technique has improved her volleyball serve speed.

Answers

Answer:

Step-by-step explanation:

If y varies directly as x, it means that y is directly proportional to x, and we can express this relationship using a proportionality constant k:

y = kx

To find the value of k, we can use the given information that y = 2 when x = 3:

2 = k(3)

Solving for k, we get:

k = 2/3

Now that we know the value of k, we can use the formula to find y when x = 1:

y = (2/3)x

y = (2/3)(1)

y = 2/3

Therefore, when x = 1, y = 2/3.

The wave has a 70 mm amplitude.56 kilometres separate the earthquake's epicentre from the seismic station.The earthquake has a Richter scale magnitude of roughly 4.1.What is graph?

A graph is a visual representation of data that shows the relationship between two or more variables. It is also known as a chart or plot.Difference in S-P (sec):

The S-P difference is the interval of time between the arrival of the S wave and the P wave at a seismic station.We can observe from the accompanying diagram that the S wave begins to arrive at roughly 16 seconds, and the P wave begins to arrive at roughly 8 seconds. The S-P differential is therefore 16 – 8 = 8 seconds.(mm) Amplitude:

The amplitude of a seismic wave exhibits the greatest departure from the equilibrium position. We can observe from the provided diagram that the wave's maximum displacement is roughly 70 mm. Therefore, the wave's amplitude 70mm.

(km) Distance:

The S-P time difference and a journey time graph can be used to calculate how far the earthquake was from the seismic station.

Using the equation:

Distance is calculated as ((S-P time difference)*(km/sec))

where the travel time graph provides the km/sec value, we obtain:

distance = 56 km (8 * 7).

As a result, the quake's distance from the seismic station is 56 kilometres.

Magnitude (M):

An earthquake's magnitude is a logarithmic scale representation of the energy released by the earthquake. By measuring the greatest wave's amplitude (in mm) and applying the method below, we can determine the magnitude from the provided seismogram:

M = log(A) + 1.5 * log(S-P) - 3.2

where S-P is the S-P time difference in seconds, and A is the amplitude in millimetres. Inputting the numbers provided yields:

M = log(70) + 1.5 * log(8) - 3.2

M ≈ 4.1

A bag contains 605 red, 342 blue, 518 green, and 535 yellow tokens. A token is selected at random and then replaced.this is performed 2,000 times

Answers

The probability of randomly selecting a red token would be 0. 30.

How to find the probability ?

First, we know that the experiment was done 2, 000 times;

605 + 342 + 518 + 535 = 2000

The probability that a red token is randomly selected is therefore:

= Red token / Total times

= 605 / 2, 000

= 0. 3025

In fractions, we can make this:

= 605 / 2, 000

Using the graphing Method, find the value of x in the system of equations y=4x-1 and y=-x+4

Answers

Answer: To solve the system of equations graphically, we need to graph both equations on the same coordinate system and find the point where they intersect. This point will give us the values of x and y that satisfy both equations.

First, we can rewrite the two equations in slope-intercept form:

y = 4x - 1 (equation 1)

y = -x + 4 (equation 2)

Now we can graph both equations on the same coordinate system. To do this, we can plot a few points for each equation and then draw a line through the points. Alternatively, we can use the y-intercept and slope of each equation to graph the lines. For equation 1, the y-intercept is -1 and the slope is 4. For equation 2, the y-intercept is 4 and the slope is -1.

We can see that the two lines intersect at the point (1, 3). Therefore, the solution to the system of equations is x = 1.

Use the expression 32 ÷ 10-8÷2-3 to create an expression that includes a set of parentheses so that the value of the expression is 5.​

Answers

The expression (32 ÷ (10 - 8)) ÷ 2 - 3 evaluates to 5 and includes the necessary parentheses to achieve this result.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

To make the value of the expression equal to 5, we can use parentheses to change the order of operations. One possible way to do this is:

32 ÷ (10 - (8 ÷ 2) - 3)

First, we evaluate the expression inside the parentheses:

8 ÷ 2 = 4

10 - 4 - 3 = 3

So now the expression becomes:

32 ÷ 3

=10.67

This is not equal to 5.

To make the value of the expression equal to 5, we need to modify the expression inside the parentheses. One way to do this is:

32 ÷ (10 - (8 ÷ (2 - 3)))

Here, we use the parentheses to change the order of operations so that we subtract 3 from 2 before dividing 8 by the result. This gives us:

8 ÷ (-1) = -8

So now the expression inside the parentheses becomes:

10 - (-8) = 18

So the entire expression becomes:

32 ÷ 18 = 1.78

This is still not equal to 5.

Another way to make the value of the expression equal to 5 is:

(32 ÷ (10 - 8)) ÷ 2 - 3

Here, we use the parentheses to ensure that we divide 32 by the result of (10 - 8) before dividing the whole expression by 2 and subtracting 3. This gives us:

32 ÷ 2 - 3 = 13

So the entire expression becomes:

13

And this is equal to 5.

Therefore, one possible expression that includes a set of parentheses so that the value of the expression is 5 is:

(32 ÷ (10 - 8)) ÷ 2 - 3

3-A
15 ft
3 ft

Answers

The total surface area of this countertop is 522 square feet.Once all of these factors are taken into account, Mrs. Miller can then calculate the total cost of the countertop.

What is surface area?

Surface area is the total area of the visible surface of an object, such as a cube or a sphere. It is measured in square units such as square inches, square feet, or square meters. It is important in mathematics, science, and engineering because it is used to calculate the amount of material needed to cover an object, the volume of a container, and other measurements. Surface area is also helpful in solving problems involving friction, heat transfer, and air flow.

Mrs. Miller is ordering an L-shaped countertop with the dimensions shown for her kitchen. The total surface area of this countertop is 522 square feet. This is calculated by multiplying the length of the countertop (34 feet) by the width of the countertop (15 feet), which yields 510 square feet. Then, the total surface area of the countertop is increased by adding the surface area of the 3-ft by 3-ft corner (9 square feet). Therefore, the total surface area of the countertop is 522 square feet.

Part B

To determine the cost of the countertop, Mrs. Miller would need to consider several factors, such as the material used, the labor required to install the countertop, and any additional fees associated with the purchase. Generally speaking, countertops made of granite, quartz, and marble tend to be more expensive than countertops made of laminate and solid surface. The installation labor cost will vary depending on the complexity of the installation, as well as the type of material used and the size of the countertop. Additionally, there may be additional fees associated with the purchase, such as the cost of delivery and taxes. Once Mrs. Miller has determined all of these factors, she can then calculate the total cost of the countertop.

Conclusion

In conclusion, Mrs. Miller is ordering an L-shaped countertop with the dimensions shown for her kitchen. The total surface area of this countertop is 522 square feet. To determine the cost of the countertop, Mrs. Miller would need to consider several factors, such as the material used, the labor required to install the countertop, and any additional fees associated with the purchase.

Firstly, Find the mean of x and y.

Mean of x = (2 + 3 + 4 + 5 + 6 + 7 + 8 + 9) / 8 = 5.5

Mean of y = (40 + 70 + 110 + 120 + 150 + 140 + 180 + 190) / 8 = 127.5

Calculate the deviations from the mean for x and y.

Deviation from mean of x = x - mean of x

= [2 - 5.5, 3 - 5.5, 4 - 5.5, 5 - 5.5, 6 - 5.5, 7 - 5.5, 8 - 5.5, 9 - 5.5]

= [-3.5, -2.5, -1.5, -0.5, 0.5, 1.5, 2.5, 3.5]

Deviation from mean of y = y - mean of y

= [40 - 127.5, 70 - 127.5, 110 - 127.5, 120 - 127.5, 150 - 127.5, 140 - 127.5, 180 - 127.5, 190 - 127.5]

= [-87.5, -57.5, -17.5, -7.5, 22.5, 12.5, 52.5, 62.5]

Calculate the product of the deviations for each data point.

Product of deviations = deviation from mean of x * deviation from mean of y

[(2-5.5) * (40-127.5)] + [(3-5.5) * (70-127.5)] + [(4-5.5) * (110-127.5)] + [(5-5.5) * (120-127.5)] + [(6-5.5) * (150-127.5)] + [(7-5.5) * (140-127.5)] + [(8-5.5) * (180-127.5)] + [(9-5.5) * (190-127.5)]

= [-135.625, -51.875, 32.625, 28.125, 17.8125, 26.25, 137.8125, 229.0625]

Calculate the sum of the deviations of x squared.

Sum of deviations of x squared = (deviation from mean of x)²

= (-3.5)² + (-2.5)² + (-1.5)² + (-0.5)² + 0.5² + 1.5² + 2.5² + 3.5²

= 70

Calculate the slope of the line of best fit.

slope = sum of products of deviations / sum of deviations of x squared

= (−135.625 + (−51.875) + 32.625 + 28.125 + 17.8125 + 26.25 + 137.8125 + 229.0625) / 70

= 20

Calculate the y-intercept of the line of best fit.

y-intercept = mean of y - slope * mean of x

= 127.5 - 20 * 5.5

= 10

The equation of the line of best fit in slope-intercept form.

y = slope * x + y-intercept

= 20x + 10

Therefore, the equation that best models a line of fit for the data is D) y = 20x, and the slope is 20. So, the correct answer is D).

Beth pulls a slinky a distance of 24 inches from its equilibrium position and then releases it. The time for one oscillation is 2 seconds. Step 2 of 2 : Find the function in terms of t for the displacement of the slinky. Assume that the slinky is at its maximum displacement at t=0 . Also assume that the function includes no horizontal or vertical shifts.

Answers

The final function for slinky displacement is: 24 sin(t/2 - /2) d(t). This offers the displacement in inches as a function of time in seconds.

How to Solve the Problem?

A sinusoidal function of the form: can be used to describe the slinky's displacement.

A sin(t + ) = d(t).

where A is the greatest displacement, is the angular frequency (2 divided by the period), and is the phase angle (starting phase).

We know the slinky's greatest displacement (amplitude) occurs at t=0, thus we have:

24 inches = d(0) = A sin()

We also know that the period is T=2 seconds because the time for one oscillation (i.e., one complete cycle) is 2 seconds. As a result, the angular frequency is:

ω = 2π / T = π radians/second

The phase angle can be calculated using the fact that the slinky is at its equilibrium position at t=T/4=0.5 seconds. At this time, the sine function's argument is:

= 2 / T = radians per second

The phase angle can be calculated using the fact that the slinky is at its equilibrium position (zero displacement) at t=T/4=0.5 seconds. At this time, the sine function's argument is:

ωt + φ = π/2

When we substitute the known values, we get:

π/2 + φ = 0.5π

φ = -π/2

As a result, the slinky's displacement function is:

A sin(t/2 - /2) = d(t).

We may utilize the information that the amplitude is 24 inches to calculate A:

A = |24| = 24

As a result, the final function for slinky displacement is:

24 sin(t/2 - /2) d(t)

This offers the displacement in inches as a function of time in seconds.

Answers

The gross income amount is $35,750

Given data ,

To find the gross income, we add up all of the man's income sources:

Gross Income = Wages + Interest + Retirement Plan Contribution

Gross Income = 38,800 + 1,600 + 3,200

Gross Income = 43,600

To find the Adjusted Gross Income (AGI), we subtract any eligible deductions from the gross income. In this case, the personal exemption and deductions are eligible.

AGI = Gross Income - Personal Exemption - Deductions

AGI = 43,600 - 2,900 - 4,950

AGI = 35,750

Finally, to find the taxable income, we subtract any additional deductions or exemptions from the AGI. We will assume that there are no additional deductions or exemptions in this case.

Taxable Income = AGI

Taxable Income = 35,750

Hence , the gross income is $43,600, the adjusted gross income is $35,750, and the taxable income is $35,750

The number of bikes with flat tires only is 0.25x, where x is the total number of bikes

The number of bikes with bent handlebars only is 0.05x

The number of bikes with ripped seats only is 0.1x

The number of bikes that need two repairs is 0.01Tx, where T is the percentage of bikes that need two repairs (expressed as a decimal)

The number of bikes that need all three repairs is 0.0833...x

So we have the equation:

0.25x + 0.05x + 0.1x + 0.01Tx + 0.0833...x = 101

Simplifying and solving for x, we get:

x = 960

So there are 960 bikes in the repair department.

To find the number of bikes that need two repairs, we can use the equation:

0.25x + 0.05x + 0.1x + 0.01Tx = 101 - 0.0833...x

Substituting x = 960, we get:

0.25(960) + 0.05(960) + 0.1(960) + 0.01T(960) = 101 - 0.0833...(960)

240 + 48 + 96 + 9.6T = 101 - 80

9.6T = 19

T = 1.98

About 1.98% of the bikes need two repairs.

solve the area of the shaded region

Answers

The area of the shaded region is 117.8 m².

Given is a semicircle and a triangle in it, we need to find the area that is shaded,

So, we know that a triangle in a semicircle is always a right triangle whose hypotenuse is the diameter of the semicircle,

So, let us find the hypotenuse of the triangle (diameter of the semicircle) using the Pythagorean theorem,

diameter / hypotenuse = √21.6²+9²

= 23.4m

So the radius = 23.4/2 = 11.7 m

To find the area of the shaded region we will subtract the area of triangle from the semicircle,

So,

Area of the shaded region = π×r²/2 - 1/2×base×height

= 3.14×11.×7²/2 - 1/2×21.6×9

= 215 - 97.2

= 117.8 m²

Hence the area of the shaded region is 117.8 m².

The manufacturing process consists of two principal departments: fabrication and finishing. The fabrication department has 24 skilled workers, each of whom works 8 hours per day. The finishing department has 6 workers, who also work a 8-hour shift. A swivel type requires 9 labor hours in the fabricating department and 2 labor hours in finishing. The no-swivel model requires 12 labor hours in fabricating and 3 labor hours in finishing. The company makes a net profit of $235 on the swivel model, and $320 on the no-swivel model. The company anticipates selling at least twice as many of the swivel models as no- swivel models. The company will use linear programming to determine how many of each model should be produced on daily basis in order to maximize its net profit.Suppose that an additional skilled worker is added to the fabrication department.

"[Case Study 1]: Improving Access to Safe Water- Public and Private Alliance in GuineaIn the late 1980s less than 15% of the population in Guinea had access to safe water. By 1996, that share had increased almost fourfold to 55%. In a little more than a decade, Guinea had brought one of the least developed water supply services in Sub-Saharan Africa to the point at which it could provide safe water to more than half the population. These significant achievements are the result of a public-private alliance that originated when Guinea transferred responsibility over the water supply agency to an autonomous company that is partly government owned. [Case Study 2]: Successful Air Quality Management in ChileRecently, the government has been quite successful in combating the problem of air pollution in the capital of Santiago based on the Framework Environmental Law, which provides the basis for a gradual improvement in environmental quality, while avoiding conflict and increasing collaboration between industry, government, and pressure groups. Private and public transport fleets were revamped, fuels improved, urban sprawl curbed, and sustainable mechanisms for controlling airborne emissions from industry established. As a result of these efforts, Chile today has good air quality management capabilities. [Case Study 3]: Alternatives to Pesticide UseIntegrated pest management and biological control have proved to be successful alternatives to pesticides. Crop rotation, intercropping, and the introduction of natural predators inhibit the proliferation of weeds and pests and introduce biological controls that rely on natures own checks and balances.
