Start by making a table for our ordered pairs.

I have done this below.

Put the x-values in the left column and y-values in right column.

---X---|---Y---

-4 | 4

-6 | 6

Now, remember that the slope is equal to rate of change

or the change in y over the change in x.

To find the change in y, we can see that the y-values go

from 4 to 6 so the change in y is 2.

The x-values go from -4 to -6 so the change in x is -2.

So the change in y over the change in x is 2/-2.

This reduces to -1.

So the slope of the line is -1.

The answer is 2/-2
Using the formula y^2-y^1/x^2-x^1

Last summers, students who worked earned an average of $80 a week with a standard deviation of $12. What percentage of students

Roman55 [17]

Answer:

2.28%

Step-by-step explanation:

Given:

μ = 80
σ = 12
x = 104

Find z-score:

z = (x - μ)/σ
z = (104 - 80)/12 = 2

Percent value corresponding to 2 as per z-table is 0.9772. This is corresponding to 97.72%.

Percentage of students earned more than $104:

100 - 97.72 = 2.28

X is normally distributed with mean 250 and standard deviation 40. what value of x does only the top 15% exceed?

lubasha [3.4K]

The top 15% (85th percentile) is the cutoff value $x$ such that

$\mathbb P(X\le x)=\mathbb P\left(\dfrac{X-250}{40}\le\dfrac{x-250}{40}\right)=\mathbb P(Z\le z)=0.85$

where $z$ is the corresponding cutoff for the standardized normal distribution. We have $z\approx1.0364$ , and so

$\dfrac{x-250}{40}=z\implies x\approx291.456$

Two rectangular prisms have the same volume. The area of the base of the blue prism is 216 square units. The area of the base of

valina [46]

Answer:

D)The height of the red prism is three times the height of the blue prism

Step-by-step explanation:

Here is the complete question

Two rectangular prisms have the same volume. The area of the base of the blue prism is 2 1/6 square units. The area of the base of the red prism is one third that of the blue prism.

which statement is true?

a)The height of the red prism is one-third the height of the blue prism

B)The height of the red prism is the same as the height of the blue prism

C)The height of the red prism is six times the height of the blue prism.

D)The height of the red prism is three times the height of the blue prism

Solution

Since both prisms have the same volume, V = A₁h₁ = A₂h₂ where A₁ and A₂ are the areas of the red and blue prisms respectively and h₁ and h₂ are the heights of the red and blue prisms respectively. For the question, A₁ = A₂/3. Substituting this into the equation, A₁h₁ = A₂h₂

A₂h₁/3 = A₂h₂

h₁ = 3h₂ . So the height of the red prism is thee times the height of the blue prism.
