Apply the formula:

x1+x2 / 2 , y1 + y2 / 2

= 3 + (-2) / 2, 5 + 1 /2

= 1/2, 6/2

the operation:

2*10^1 - 4*10^0 = 20 - 4 = 16

Gives a square number.

<h3>How to get a perfect square?</h3>

A perfect square is the product of a number and itself.

As you can see in the example, 16 is a square number. Then let's try to get 16.

To get 16 we can use the difference:

20 - 4

So the first therm needs to be equal to 20, and the second equal to 4.

To write 20 in scientific notation we have:

2*10^1

To write 4 in in scientific notation:

4*10^0

Then the operation:

2*10^1 - 4*10^0 = 20 - 4 = 16

Gives a square number.

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
