Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and st

SashulF [63]

Answer:

0.7233

Step-by-step explanation:

We want to find the area between the z-scores z=-0.95 and z=1.25.

We first find the area to the left of each z-score, and subtract the smaller area from the bigger one.

For the area to the left of z=-0.95, we read -0.9 under 5 from the standard normal distribution table.

This gives P(z<-0.95)=0.1711

Similarly the area to the left of z=1.25 is

P(z<1.25)=0.8944

Now the area between the two z-scores is

P(-0.25<z<1.25)=0.8944-0.1711=0.7233

Answer:

(d) domain: 0 ≤ x ≤ 4; range: -1 ≤ y ≤ 7

Step-by-step explanation:

The graph of the inverse of a function is a reflection of the function's graph across the line y=x. The table values are obtained by swapping the x- and y-labels. This is shown in the attachment.

A tennis court measures 23.2 m by 12 m. What is its perimeter?

posledela

To get perimeter, you simply add all the side lengths. So we will ad 23.2 + 23.2 + 12 + 12 = 70.4

The perimeter is 70.4 m

A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank AAA holds 40\tex

bearhunter [10]

Answer:

C, A and B

Step-by-step explanation:

Tank A holds 40 Liters and 5 fish.

Volume per fish of Tank A $=40 \div 5 =$ 8 fish per liter$

Tank B holds 100 Liters and 12 fish.

Volume per fish of Tank B $=100 \div 12 =$ 8.33 fish per liter$

Tank C holds 180 Liters and 23 fish.

Volume per fish of Tank C $=180 \div 23 =$ 7.83 fish per liter$

Therefore, the volume per fish from least to greatest is:

7.83, 8 and 8.33

These correspond to the tanks: C, A and B respectively.
