Answer:
Both the values fall in the critical region so we reject H0: p ≤ 0.01 and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.
Step-by-step explanation:
1) Formulate the hypothesis
H0: p ≤ 0.01 against the claim Ha: p > 0.01
2) Choose the significance level ∝= 0.01
3) The test statistics under H0 is
z= x -np /√npq ( without continuity correction)
z= x ± 1/2 -np /√npq ( with continuity correction)
4) the critical region is z> ±2.33 because the alternate hypothesis is stated on greater than basis.
5)Computations:
Z= x -np /√npq ( without continuity correction)
Z= 6- 600( 0.03)/√ 600( 0.03)(0.97)
z= - 2.82 ( without continuity correction)
z= x ± 1/2 -np /√npq ( with continuity correction)
Z= (6-0.5)- 600( 0.03)/√ 600( 0.03)(0.97)
z= -12.5/4.1785
z= -0.29915 ( with continuity correction)
6) Both the values fall in the critical region so we reject H0: p ≤ 0.01 and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.

what is angle ?A geometric shape known as an angle is created when two rays or line segments come together to form its vertex. The two rays or line segments are known as the angle's sides. Angles are used to describe the orientation, direction, and position of lines and forms in geometry. They are commonly measured in degrees or radians. The magnitude of an angle can range from 0 degrees (representing no rotation) to 360 degrees depending on how much the two sides or rays are rotating (corresponding to a full rotation).
given
We may utilise the Law of Cosines to determine the potential values of U:
A2 + B2 - 2ab cos = c2 (C)
where a and b are the lengths of the other two sides, and c is the length of the side that faces angle C. We'll write c for the length of side SU and a for the length of side ST.
Based on the facts provided, we can:
a=630 inches
b = u (unknown) (unknown)
C = ∠T = 7°
We can apply the Law of Sines to determine the length of b:
B = a / sin = b / sin(B) (A)
where A denotes the angle that faces side a, and B denotes the angle that faces side b. To solve for b, we obtain: b = a / sin(B) (A) .

1. What is the equation of a parabola that has a vertex at (-2, 4) and goes through the point (0,8)?
Answer:
y - k = (x + 2)^2
Step-by-step explanation:
The vertex equation of a vertical parabola is
y - k = a(x - h)^2, where (h, k) is the vertex.
We are given h = -2, k = 4, x = 0 and y = 8 and need to find the value of a.
8 - 4 = a(0 + 2)^2, or
4 = 4a, so a must be 1.
Then the desired equation is:
y - k = (x + 2)^2

Which graph shows y=⌊x⌋+2?
In the following graph is the zero located at -4 have an
even or odd multiplicity?
Answer:
Even multiplicity at x = -4
Step-by-step explanation:
If the graph of a function crosses x-axis then the multiplicity of the function at that zero will be odd.
If the graph touches the x-axis at a point then the function will have an even multiplicity at the particular zero.
From the given graph graph touches the x-axis at x = -4
Therefore, multiplicity of the function is even at x = -4
Find the other endpoint of the line segment with the given endpoint and midpoint
Endpoint: (3,5)
Midpoint: (7, -2)
Answer:
The other endpoint is (11,-9)
Step-by-step explanation:
Midpoint Formula
[tex]\large\boxed{(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )}[/tex]
We already know the another endpoint which is (3,5). We substitute x = 3 and y = 5 in the formula. You can substitute in x1, x2 or y1, y2. I'll substitute in first x-term and first y-term instead.
[tex]\large{\begin{cases} \frac{3+x}{2}=7\\\frac{5+y}{2}=-2 \end{cases}}[/tex]
Because sum of two x-coordinate (along with y-coordinate) divided by two must equal to the midpoint (Let's say that you get the value of midpoint when using midpoint formula.)
Solve the equation for both terms.
[tex]\large{\begin{cases} \frac{3+x}{2}=7\\\frac{5+y}{2}=-2 \end{cases}}[/tex]
Cancel the denominator by multiplying the whole equation by 2.
[tex]\large{\begin{cases} \frac{3+x}{2}(2)=7(2)\\\frac{5+y}{2}(2)=-2(2) \end{cases}}\\\large{\begin{cases} 3+x=14\\ 5+y=-4 \end{cases}}[/tex]
Isolate x-term and y-term.
[tex]\end{cases}}\\\large{\begin{cases} 3+x=14\\ 5+y=-4 \end{cases}}\\\end{cases}}\\\large{\begin{cases} x=14-3\\ y=-4-5 \end{cases}}\\\end{cases}}\\\large{\begin{cases} x=11\\ y=-9 \end{cases}}[/tex]
Therefore, when x = 11, y = -9. We can write in ordered pair as (11,-9). The ordered pair (11,-9) is our other endpoint of the line segment. This can be proved by using the distance formula between midpoint and endpoints.
Note: The distance of (3,5) and (7,-2) must equal to the distance of (11,-9) and (7,-2)

Step-by-step explanation:
Doctors are interested in seeing if lifting weights to alleviate back pain is effective. Twenty five volunteers are asked to rank their level of pain on a scale from one to ten. For the next two months, they then exercise for 2 months with a physical therapist. The volunteers focus on different weight lifting exercises that strengthen the back. Twenty five volunteers are again asked to rank their level of pain on a scale from one to ten. Was the amount of pain less after completing the exercises? What type of test would they conduct to test this claim?
Answer:
Comparing means from dependent samples.
Step-by-step explanation:
In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.

There is a population of 17 bacteria in a colony. If the number of bacteria doubles every 229 hours, what will the population be 458 hours from now?
Answer:
68
Step-by-step explanation:
Step 1: Divide the asked hours by hours need to double
Step 2: Double the initial number of the population as per the result from step 1.
First divide 458 by 229, you will get 2
Now you double the initial population number twice
so 17 * 2 = 34 and again 34 * 2 = 68

Option 3 (C)
Step-by-step explanation:
Given the scores of the students: 3, 4, 4, 5, 5, 6, 8, 10, 10, 12, 15, 18
To find the box plot that represents the data set, we need to find:
Min, Q1, median, Q3, and Max, which are all represented on a box plot.
Min = 3
Max = 18
Median = the average of the 6th and 7th data value = (6+8)/2 = 14/2 = 7
Q1 = the average of the 3rd and 4th data values = (4+5)/2 = 4.5
Q3 = the average of the 9th and 10th data values = (10+12)/2 = 11
The box plot that closely represented all these values is the box plot in option 3.
Walden’s family is shopping for a reclining chair. The chair the family decided on has a retail price of $800 plus 5% sales tax at four stores. Each store is offering a different promotion.
Store
Promotional Offer
A
$75 instant rebate
B
10% off sale
C
5% off sale plus store pays sales tax
D
a “no tax” sale—the store pays the tax
Which store has the best deal?
Answer: B is the correct answer
Step-by-step explanation:
If you do the math for each question to get a price a leaves you with 725 and b leaves you with 720 and c leaves you with 760 while d leaves you paying 800 so the lowest amount would be B.
Answer: B
Step-by-step explanation:
I'm pretty sure its B.
Since all 4 stores have a 5% sales tax already on them, we do:
800 x 5%
800 x 5/100
800 x 0.5 = 40
So now we go to all the stores and see which one is less than $40.
Answer A = 40 - 75 = -35 (Which is a price the store would have to pay but that's not a good option)
Answer B = 4
40 x 10%
40 x 10/100
40 x 0.10 = 4
Answer C = So if the store already pays sales tax which would be the 5% then our answer is $40
Answer D = This would just be $800 since the store says "no tax" and the store pays the 5%.
So, i'm pretty sure the answer is B instead of C. (i say this because a lot of people were saying it was C but C is completely wrong.)

The formula for the area of the shaded region on the diagram is: Area of the circle - Area of the square The area of the circle is 76.8 cm2 rounded to 1 decimal place. The area of the square is 12.7 cm2 truncated to 1 decimal place. Write the error interval for the area, a , of the shaded region in the form m < a < n .
The error interval for the area is 64.2< a < 63.93
What is error interval?Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.
Given:
Area of circle = 76.9 cm²
Area of square = 12.7 cm²
Now, 1 decimal point
Area of circle,
= 76.9+0.05 and = 76.9-0.05
= 76.95 and = 76.85
Area of square,
= 12.7-0.05 and = 12.7+-0.05
=12.65 and = 12.75
Area of shaded region in the form m < a < n .
m= 76.95-12.75
m= 64.2
n= 76.85-12.65
n= 63.93
Area of shaded region is 64.2< a < 63.93.

A company is designing a new cylindrical water bottle. The volume of the bottle will be 124 cmcubed. The height of the water bottle is 7.1 cm. What is the radius of the water bottle? Use 3.14 for pi.
Answer:
2.35cm
Step-by-step explanation:
Given data
Volume= 124cm^3
Height= 7.1cm
The expression for the volume of a cylinder is given as
V= πr^2h
substitute
124=3.142*r^2*7.1
124=22.3082r^2
r^2= 124/22.3082
r^2= 5.55
r= √5.55
r=2.35cm
Hence the radius of the cylindrical bottle is 2.35cm
