You're looking for a value

such that

Because the distribution is symmetric, the value of

in either case will be the same.
Now, because the distribution is continuous, you have that

The mean for the standard normal distribution is

, and because the distribution is symmetric about its mean, it follows that

.

You can consult a

score table to find the corresponding score for this probability. It turns out to be

.
Change the common denominator so 3/4 ---> 9/12
3/4 and 9/12 are equal
Hope this helps!!!
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

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.
