Find the missing side of each triangle. Round your answers to the nearest tenth if necessary.

The number of real zeros for the function whose graph is shown include the following: D. 0.

In Mathematics and Geometry, a polynomial function can be defined as a mathematical expression which comprises intermediates (variables), constants, and whole number exponents with different numerical value, that are typically combined by using mathematical operations.

This ultimately implies that, a polynomial graph touches the x-axis at real zeros, roots, solutions, x-intercepts, and factors with even multiplicities.

In this context, we can reasonably and logically deduce that the real zeros of a polynomial function are all of the values (x-intercepts) on the x-coordinate that makes this polynomial function equal to zero and it is non-existent on the graph above.

Answer:

x=7

(x)(x+1)=(4)(4+10)

Step-by-step explanation:

Expanding the right-hand side of the equation, we get:

(x)(x+1) = (4)(14)

Simplifying, we get:

x^2 + x = 56

Moving all terms to the left-hand side, we get:

x^2 + x - 56 = 0

Now we can factor this quadratic equation:

(x + 8)(x - 7) = 0

So the solutions are x = -8 or x = 7.

Answer: X=7

Step-by-step explanation:

To Solve this problem we have to remember a formula regarding secants in circles it states (A+B)*B=(C+D)*D, I have attached said Theorem. This is Exactly what your problem is asking.

So First

B = 4

A = 10

D = x

C = 1

(A+B)*B=(C+D)*D

(10+4)*4=(1+x)*x

14*4=x²+x

-x²-x+56=0

Using Quadratic Formula

X = 7, X = -8

Since you cant have - side length X= -8 is Extraneous

Thus Final solution is X = 7

The cost of ending inventory using the weighted-average method is $198.24.

An ending inventory is often derived by adding new purchases to beginning inventory and then subtracting the cost of goods sold.

To calculate it using the weighted-average, we must compute the weighted average cost per unit and then multiply the weighted average cost per unit by the number of units in ending inventory to get the cost of ending inventory.

The total cost of goods available for sale is:

= (4 x 1.50) + (11 x 2.00) + (11 x 2.50) + (16 x 2.75) + (17 x 3.50) + (21 x 3.70) + (31 x 3.90) + (17 x 4.30)

= $430.7

The total units available for sale is:

= 4 + 11 + 11 + 16 + 17 + 21 + 31 + 17

= 128

The weighted average cost per unit is:

= $430.70 / 128 units

= $3.36484375

= $3.36

The cost of ending inventory will be:

= 59 units x $3.36

= $198.24

The ratio of the circumference of a circle with radius r to its area is 2:r or 2 to r.

A circle is a two-dimensional shape that is defined as the set of all points in a plane that are at a fixed distance, called the radius, from a given point, called the center. The distance around the circle is called the circumference, and the distance across the circle passing through the center is called the diameter.

The circumference of a circle with radius r is given by the formula:

C = 2πr

The area of a circle with radius r is given by the formula:

A = π×r²

Therefore, the ratio of the circumference of a circle with radius r to its area is:

C/A = (2πr) / (πr²)

Simplifying the expression by canceling out π and r from the numerator and denominator, we get:

C/A = 2/r

Therefore, the ratio of the circumference of a circle with radius r to its area is 2:r or 2 to r.

Thus, radius of the smaller cylinder is found as the 0.08 cm, for the given ratio of surface areas.

A cylinder's surface area provides information on how much space is present on the whole surface of the cylinder. If you were to use wrapping paper to wrap a can of Pringles as a birthday gift, then amount required would be equal towards the surface area of a Pringles can.

Let the surface area of smaller cylinder be s.

Let the  surface area of larger cylinder be S.

ratios of surface area:

s/S = 4 / 25

Radius of larger cylinder = 0.5 cm.

As,both cylinders are similar height will be same.

The formula for the surface area = 2*π*r*h

Put the values in ratio:

2*π*r*h / 2*π*R*h = 4 / 25

r / 0.5 = 4/25

cross multiplying:

r = 0.5*4 / 25

The range of the monthly rainfall data for the cities is approximately 7 centimeters.

To find the range of the data from the given box plot, we need to determine the highest and lowest values of the dataset. Looking at the box plot, we can see that the "H" represents the high outlier and the "□" represents the low outlier. The vertical line at the bottom of the box represents the minimum value and the vertical line at the top of the box represents the maximum value of the dataset within the interquartile range.

Using the scale on the x-axis, we can estimate the minimum value to be around 0.5 centimeters and the maximum value to be around 7.5 centimeters. The high outlier is located at around 8 centimeters and the low outlier is located at around 0 centimeters.

Therefore, the range of the data is the difference between the highest and lowest values, which is:

Answer: The volume of the prism is 4200 cubic units.

Explanation:

The volume of a prism is given by the formula V = Bh, where B is the area of the base and h is the height. For a hexagonal base with a side length of 10, we can divide it into six equilateral triangles with side lengths of 10. Each equilateral triangle has an area of (1/2)bh, where b is the base and h is the height. Since the base of each equilateral triangle is also 10, we have:

Area of one equilateral triangle = (1/2)(10)(10√3/2) = 50√3

Area of the hexagonal base = 6 times the area of one equilateral triangle = 6(50√3) = 300√3

Now we can use the formula for the volume of a prism:

V = Bh = (300√3)(14) = 4200 cubic units.

Therefore, the volume of the prism is 4200 cubic units.

Answer:The sample space that satisfies the definition of a continuous random variable is: ×=[0,500]

Step-by-step explanation:

The sample space that satisfies the definition of a continuous random variable is: ×=[0,500]

A continuous random variable is a variable that can take on any value within a certain range of values, typically a continuous interval. This means that there are an infinite number of possible values that the variable can take on, and the probability of any particular value is zero.

In contrast, the other sample spaces listed are all discrete random variables, meaning that they can only take on a finite or countable number of values. For example, the first sample space x={odd integers between 5 and 15} can only take on 6 possible values (5, 7, 9, 11, 13, or 15), and the third sample space x=[0,1,2,3] can only take on 4 possible values.

The fourth sample space x=[the number of days in the week that have the letter "r"] is also a discrete random variable, as it can only take on values of 0, 1, 2, or 3 (depending on how many days of the week have the letter "r").

Therefore, the only sample space that satisfies the definition of a continuous random variable is ×=[0,500].

The probability that fewer than 18 people from this sample were between the ages of 25 and 34 is 0.1089 (or 10.89%).

Using the normal approximation to the binomial distribution, the mean (μ) of the sample is:

μ = np = 90 x 0.26 = 23.4

The standard deviation (σ) of the sample is:

σ = √(np(1-p)) = √(90 x 0.26 x 0.74) = 4.37 (rounded to 4 decimal places)

To find the probability that fewer than 18 people from this sample were between the ages of 25 and 34, we need to calculate the z-score:

z = (x - μ) ÷ σ = (18 - 23.4) ÷ 4.37 = -1.24

Using a standard normal table or calculator, we find that the probability of a z-score less than -1.24 is 0.1089.

0.1089 = 10.89%

Answer:

The IQR (interquartile range) of 13 is the most accurate measure of variability to use in this case, since the data is skewed and contains some outliers.

The IQR is a measure of variability that is less sensitive to extreme values than the range, and is calculated as the difference between the upper and lower quartiles (the 75th and 25th percentiles). It provides a measure of the spread of the middle 50% of the data, which is useful for understanding the typical range of donations received.

In this case, the IQR is calculated as follows:

- The median of the data is 51 (the value in the middle).

- The lower quartile (Q1) is the median of the lower half of the data, which is 42.

- The upper quartile (Q3) is the median of the upper half of the data, which is 54.

- The IQR is the difference between Q3 and Q1: IQR = Q3 - Q1 = 54 - 42 = 12.

So the IQR of 13 is a useful measure of variability to use for this data set, since it captures the spread of the middle 50% of the data while being less sensitive to the outliers at the higher end of the distribution.

The mean absolute deviation of 8,2,7,8,6,10,2,1,10,6 is 2.24.

To calculate the mean absolute deviation, we first need to find the mean of the data set. The mean is the sum of all the values in the data set divided by the number of values. In this case, the mean is 7.

Once we have the mean, we can find the mean absolute deviation by finding the absolute value of the difference between each value in the data set and the mean. For example, the absolute value of the difference between 8 and 7 is 1. We then add up all of the absolute values and divide by the number of values in the data set. In this case, the mean absolute deviation is 2.24.

Here is the formula for the mean absolute deviation:

Answer:

Let x be the amount of the first alloy (30% gold) to be mixed and y be the amount of the second alloy (80% gold) to be mixed.

We can set up a system of two equations based on the information given:

x + y = 40 (total amount of alloy produced)

0.3x + 0.8y = 0.6(40) (amount of gold in the alloy produced)

Simplifying the second equation, we get:

0.3x + 0.8y = 24

Now we have a system of two equations:

x + y = 40

0.3x + 0.8y = 24

We can solve for x and y by using any method of solving systems of equations. Here, we will use the substitution method.

Solving the first equation for y, we get:

y = 40 - x

Substituting this expression for y into the second equation, we get:

0.3x + 0.8(40 - x) = 24

Simplifying and solving for x, we get:

0.3x + 32 - 0.8x = 24

-0.5x = -8

x = 16

So we need 16 grams of the first alloy and 24 grams of the second alloy to produce 40 grams of an alloy that is 60% gold.
