The triangle is given as equilateral and the length of the perpendicular of the given equilateral triangle is 13.85.

It states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the hypotenuse, the longest side of the triangle. This theorem can be used to determine the length of the sides of a right triangle if two sides are known.

The triangle is given as equilateral. As we know he perpendicular in a equilateral triangle divides a line into to equal parts, so

Base= 8+8

= 16

As it is a equilateral triangle, all the sides will be equal.

Now, we can use the Pythagorean theorem to find the length of the perpendicular, which can be found by using the formula:

16²= 8² + x²

x² = 16²- 8²

x = √192

x = 13.85

Thus, the length of the perpendicular of the given equilateral triangle is 13.85.

(a) There is no statistically significant relationship between race and receiving services from the program.

(b) Black homeless people were more likely to receive services (60%) than white homeless people (43.75%).

a. To test whether there is a statistically significant relationship between race and whether the person received services from the program, we can use a chi-squared test of independence.

The null hypothesis is that there is no relationship between race and receiving services, and the alternative hypothesis is that there is a relationship.

Using a chi-squared calculator, we obtain a chi-squared statistic of 0.267 and a p-value of 0.605. Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis and conclude that there is no statistically significant relationship between race and receiving services from the program.

b. To compute column and row percentages, we can first calculate the total number of black and white homeless people who received services and who did not receive services:

We can also calculate the percentage of all homeless people who received services or did not receive services, by adding up the numbers in each column:

The base, lateral area and surface area is B = 96 cm², L = 499.2 cm²,S = 691.2 cm²

The lateral area for the triangular prism is the sum of all three areas. Thus, the formula for lateral area of triangular prism, Lateral surface area of triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h.

To find the lateral area (L) of this solid, we need to calculate the area of the four rectangles that make up the sides of the solid. Since each rectangle has a height of 10.4 cm and a width of 12 cm, the area of one rectangle is:

A = 10.4 cm * 12 cm = 124.8 cm²

Since there are four rectangles, the total lateral area is:

L = 4 * A = 4 * 124.8 cm² = 499.2 cm²

To find the surface area (S) of the solid, we need to add the lateral area to the area of the two circular bases. The base area is given as 96 cm², so the area of both bases is:

A = 2 * 96 cm² = 192 cm²

Therefore, the total surface area is:

S = L + A = 499.2 cm² + 192 cm² = 691.2 cm²

The probability of the store manager selecting 2 comedies and 1 action movie out of the new list of 15 movies is 0.165

Using this formula, we can find the total number of ways in which the manager can select any 3 movies from the list of 15, which is:

¹⁵C₃ = 455

Next, we need to determine the number of ways in which the manager can select 2 comedies and 1 action movie out of the list of 15 movies. To do this, we first need to determine the total number of comedies and action movies in the list, which is 4 and 5, respectively.

Answer: The given function is:

N = 81s / (20 + 20(s/24)^2)

where:

N = number of cars that can pass a given spot per minute

s = speed of the cars in miles per hour (mph)

To find the maximum number of cars that can safely travel on the road at a given speed, we need to find the value of s that maximizes the function N.

Taking the derivative of N with respect to s:

dN/ds = (81 / (20 + 20(s/24)^2)) * (20/24 - (2s/24^2) * (s/24))

Setting dN/ds to zero to find the critical point:

0 = (81 / (20 + 20(s/24)^2)) * (20/24 - (2s/24^2) * (s/24))

Simplifying and solving for s:

20/24 = (2s/24^2) * (s/24)

20 * 24 = 2s * s

s^2 = (20 * 24) / 2

s^2 = 240

s = sqrt(240)

s ≈ 15.4919 mph

Therefore, the maximum number of cars that can safely travel on the road at a speed of 15.4919 mph is:

N = 81s / (20 + 20(s/24)^2) = 81(15.4919) / (20 + 20((15.4919)/24)^2) ≈ 180.19 cars per minute.

This data would be considered "paired" data.

The population of ferrets from which our sample was drawn, represented as μd, where μd = μend - μstart, and μ represents the population mean.

       We are dealing with "paired" data since we are comparing the weights of the same ferrets at two different points in time.

      The parameter we are trying to estimate is the mean difference in weight between the start and end of the study for the population of ferrets from which our sample was drawn.

This mean difference in weight can be represented as μd, where μd = μend - μstart, and μ represents the population mean. To estimate this parameter, we would need to calculate the difference in weight for each ferret and then take the average of these differences. This estimate would then provide us with an understanding of how much, on average, the ferrets in the population have gained or lost weight over the course of the study.

We can use the formula for the slope of a line, which is:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

Using the first two points from the table, we get:

Therefore, the volume of the rectangular prism is 87.5 cubic yards.

A prism is a transparent object, usually made of glass or plastic, that refracts or bends light as it passes through it. It has at least two flat surfaces, called faces, that are usually parallel and rectangular in shape, and two non-parallel faces, called bases, which are usually triangular in shape. When light enters a prism, it is refracted, or bent, as it passes through the prism and is separated into its component colors, creating a rainbow effect. Prisms are often used in optics and science experiments to study the properties of light, such as its wavelength and polarization. They are also commonly used in optical instruments such as binoculars, telescopes, and cameras to help focus and direct light.

The volume V of a rectangular prism is given by the formula:

V = length x width x height

In this case, the length is 5 yards, the width is also 5 yards, and the height is 3- and one-half yard.

The area of the sandbox of parallelogram shape is approximately 22.47 square feet. Rounded to the nearest integer, the answer is (a) 24ft².

A parallelogram is a quadrilateral with two pairs of parallel sides. Opposite sides of a parallelogram are equal in length and parallel to each other. Additionally, opposite angles of a parallelogram are congruent (i.e., have the same measure).

We can choose any side of the parallelogram as the base, and the distance from that side to the opposite side as the height. Let's choose the side between (-4,0) and (-2,6) as the base. The length of this side is the distance between these two points:

√[(-2-(-4))² + (6-0)²] = √40 = 2√10

The height of the parallelogram is the distance between the line containing (-2,6) and (4,0) and the point (2,-6). We can find the equation of the line containing (-2,6) and (4,0) by finding the slope and y-intercept:

Slope: (0-6)/(4-(-2)) = -6/6 = -1

Y-intercept: y = mx + b -> 0 = (-1)(4) + b -> b = 4

Therefore, the equation of the line is y = -x + 4. We can find the distance between this line and the point (2,-6) by substituting x = 2 into the equation and finding the corresponding y-value:

y = -x + 4 = -2

The distance between the line and the point (2,-6) is the absolute value of the difference between the y-coordinate of the point and the y-coordinate of the line:

|(-6) - (-2)| = 4

Therefore, the height of the parallelogram is 4 feet.

The area of the parallelogram is then:

A = base x height = (2√10) x 4 = 8√10

Rationalizing the denominator, we get:

A = 8√10 x √10/√10 = 80/√10 = 80√10/10 = 8√10

Therefore, the area of the sandbox is approximately 22.47 square feet. Rounded to the nearest integer, the answer is (a) 24ft².

When two figures are congruent, they can be superimposed on each other without any overlap or gap between them. Congruent figures are often denoted by the symbol ≅. For example, if two triangles have the same size and shape, we can write them as ∆ABC ≅ ∆DEF, which means that triangle ABC is congruent to triangle DEF. Congruent figures play an important role in geometry and other branches of mathematics.

Yes, the two triangles are congruent.

In Euclidean geometry, if two angles and a side of one triangle are equal to two angles and a side of another triangle, then the two triangles are congruent. This is known as the angle-side-angle (ASA) congruence criterion.

In this case, both triangles have a side length of 5 units and a side length of 7 units, and they share an angle of 117 degrees. Therefore, they satisfy the ASA criterion, and we can conclude that they are congruent.

The  Area of shaded region is  6 (w- 4).

We have,

length= w unit

shorter length = 4 unit

width = 6 unit

So, Area of larger rectangle

= l w

= 6 x  w

and, Area of smaller rectangle

= l w

=  6 x 4

= 24 cm²

So, the Area of shaded region

= 6w - 24

= 6 (w- 4)
