What is the slope of the line through the points (-2, -1) and (4, 3)? ​

Answer: 7

Step-by-step explanation:

[tex]Mean = \frac{Sum of terms}{Number of terms}[/tex]

          = [tex]\frac{7+6+6+7+6+9+7+8}{8}[/tex]

          = [tex]\frac{56}{8}[/tex]

          = 7

Answer:

Part A: 12.5 cm

Part B: 0.8 km

Step-by-step explanation:

Map scale problems can be solved with proportions.

Part A

5 cm / 2 km = x cm / 5 km

5/2 = x/5

2x = 25

x = 12.5

Answer: 12.5 cm

Part B

5 cm / 2 km = 2 cm / x km

5/2 = 2/x

5x = 4

x = 4/5

x = 0.8

Answer: 0.8 km

Answer:

7/3

Step-by-step explanation:

12x - 15 = 6 - 3x

=> 12x + 3x =  6 + 15

=> 15x = 21

=> x = 21/15

=> x = 7/3

Answer:

for the first answer the second option is correct and 8 will go in the box and for the second question the second option is correct and 40 will go in the box.

All vertical lines intersected the curve at exactly 1 point.

===========================================================

Explanation:

If there is a case when a single vertical line crosses 2 or more points on the  curve, then it will not be a function. In this situation, it is said that the curve fails the vertical line test.

Passing the vertical line test means that every vertical line passes through exactly one point on the curve. Each x input leads to exactly one output. If such a situation happens, then we have a function.

Since Kelly concluded that the curve is a function, this means the curve passed the vertical line test, and it points us to choice D as the answer.

Answer:

x=4

Step-by-step explanation:

We know that in a parallelogram opposite sides are equal

Hence on equating we get,

[tex]6x - 20 = 4[/tex]

[tex]6x = 4 + 20[/tex]

[tex]6x = 24[/tex]

[tex]x = 4[/tex]

Using the normal distribution, it is found that 56.78% of the penguins from the population have a weight between 13.0 kg and 16.5 kg.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by [tex]\mu = 15.1, \sigma = 2.2[/tex].

The proportion of penguins from the population have a weight between 13.0 kg and 16.5 kg is the p-value of Z when X = 16.5 subtracted by the p-value of Z when X = 13.

X = 16.5:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{16.5 - 15.1}{2.2}[/tex]

Z = 0.64

Z = 0.64 has a p-value of 0.7389.

X = 13:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{13 - 15.1}{2.2}[/tex]

Z = -0.95

Z = -0.95 has a p-value of 0.1711.

0.7389 - 0.1711 = 0.5678.

0.5678 = 56.78% of the penguins from the population have a weight between 13.0 kg and 16.5 kg.

Step-by-step explanation:

The volume of the triangular prism is 1756.3 cubic yd option second is correct.

It is defined as a three-dimensional space enclosed by an object or thing.

We know that the volume of a triangular prism is given by:

[tex]\rm V = \dfrac{1}{2}\times b\times l\times h[/tex]

Where b is the base length, l is the base width, and h is the height of the prism.

[tex]\rm h=\sqrt{13^2-(\dfrac{13}{2}) ^2[/tex]

h = 11.2583 yd

b = 13 yd

l = 24 yd

[tex]\rm V = \dfrac{1}{2}\times 13\times 24\times 11.2583[/tex]

V = 1756.29 ≈ 1756.3 cubic yd

Thus, the volume of the triangular prism is 1756.3 cubic yd option second is correct.

Answer:

[tex]27cm^{2}[/tex]

Step-by-step explanation:

Area of compound shapes = Area of shape A + Area of shape B

Area of this shape = (L x B) + (L x B)
                               = (5 x 3) + (6 x 2)
                               = 15 + 12
                               = [tex]27cm^{2}[/tex]

Answer:

A = 27 cm²

Step-by-step explanation:

the figure consists of 2 rectangles

the one on the right with dimensions 2 cm by 6 cm and

the one on the left with dimensions 5 cm by 3 cm

the total area (A) is then calculated as

A = (2 × 6) + (5 × 3) = 12 + 15 = 27 cm²

Answer:

IF the base area of the pyramid will be 400 square feet. Then the volume of the given pyramid will be 3466.67 cubic feet.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The dimension of the pyramid is shown in the diagram.

Then the base area of the pyramid will be

Area = 20 x 20

Area = 400 square feet

Then the volume of the given pyramid will be

V = 1/3 x area x height

V = 1/3 x 400 x 26

V = 3466.67 cubic feet
