In a standard normal distribution, what z value corresponds to 17% of the data between the mean and the z value?
hjlf
You're looking for a value z such that

\mathbb P(0

Because the distribution is symmetric, the value of z in either case will be the same.

Now, because the distribution is continuous, you have that

0.17=\mathbb P(0

The mean for the standard normal distribution is 0, and because the distribution is symmetric about its mean, it follows that \mathbb P(Z.

0.17=\mathbb P(Z

You can consult a z score table to find the corresponding score for this probability. It turns out to be z\approx0.4399.

If a^2+b^2= 4 and ab = 5, what is the value of<br> (a+b)^2?<br> A. 10<br> B. 12<br> C. 14<br> D. 16
wlad13 [49]

Answer:

14

Step-by-step explanation:

(a+b)^2

(a+b)(a+b)

FOIL

a^2 + ab+ab + b^2

Combine like terms

a^2 +2ab + b^2

Rearranging

a^2+b^2 +2ab

We know a^2+b^2 = 4  and ab= 5

4 + 2(5)

4+10

When diving, a bald eagle can reach a speed of 200 miles per hour. What is this speed in feet per second? Round to the nearest h
LenaWriter [7]

Answer:

A mile is equal to 5280 feet

You start off with

200 miles per hour

If you multiply 200 by 5280 you can find the speed in feet per hour

1,056,000 feet per hour

There are 60 minutes in an hour

If you divide 1,056,000 by 60 you can find the speed in feet per minute

So 17,600 feet per minute

Then if you divide that by 60 you can find the speed in feet per seconds

It is 293 1/3 or 293.333 feet per second.
