Does anybody know this ?

Aleonysh [2.5K]

Answer:

0, 1, 2, 3, 4

Step-by-step explanation:

Multiply each x value by 1/3 then add 2. Since the numerator is 1, you would multipy by one and divide by the denominator of 3, so you really need to divide each x value by 3 then add 2.

-6:

-6/3 = -2

-2 + 2 = 0

-3:

-3/3 = -1

-1 + 2 = 1

0/3 = 0

0 + 2 = 2

3/3 = 1

1 +2 = 3

6/3 = 2

2 + 2 =4

The heights of American men have an approximately bell-shaped distribution with a mean of 70 inches (5' 10") and standard deviat

Katyanochek1 [597]

Answer:

0.9973 is the percentage of American men whose height is between 61 and 79 inches.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 70 inches

Standard Deviation, σ = 3 inches

We are given that the distribution of heights of American men is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(height is between 61 and 79 inches)

$P(61 \leq x \leq 79) = P(\displaystyle\frac{61 - 70}{3} \leq z \leq \displaystyle\frac{79-70}{3}) = P(-3 \leq z \leq 3)\\\\= P(z \leq 3) - P(z < -3)\\= 0.9987 - 0.0014 = 0.9973= 99.73\%$

$P(61 \leq x \leq 79) = 99.73\%$

0.9973 is the percentage of American men whose height is between 61 and 79 inches.

STAN walk 10 km to the grocery store. He stops then walks 10 km east back to his house. What distance does he cover? what was hi

Bogdan [553]

STAN walk 10 km to the grocery store.

He stops then walks 10 km east back to his house.

Let us draw this situation to better understand the problem.

As you can see, Stan first walked to the grocery store and covered a distance of 10 km then he came back to the house from the grocery store and covered a distance of 10 km.

So the total distance is 10 + 10 = 20 km

On the other hand, notice that Stan is exactly at the point where he first started that is his house, therefore, the displacement is 0 in this case.

Recall that the displacement is a vector quantity so the direction of travel also matters.

From house to grocery store = 10 km

From the grocery store to house = -10 km

Overall displacement = 10 km - 10 km = 0 km

Therefore,

Distance = 20 km

Displacement = 0 km

Amelia is building 3 square garden beds that are all the same size. She arranges them side-by-side to seperate the certain plant

bazaltina [42]

Answer:

3(s x s)

Step-by-step explanation:

You can find the area of each garden bed by multiplying the length of each square, and since a square has four equal sides, the area of one square would be s times s. S times s equals the area of ONE square, so you would take that area and multiply it by three, since you have three squares. Hope this helps!
