0.84(because 20% of the observations are about 0.84)
You've found the 80th percentile! The 80th percentile of the standard normal distribution is 0.84. That's because 80% of the observations fall below 0.84. (Note: The 80th percentile of every normal distribution is 0.84 times the standard deviation above the mean.)
Answer:
A
Step-by-step explanation:
The reason it has to be A is because you don't have to even thing about the standard deviation right here because the only answer that has a mean of 131 is answer A.
Hope it helps have a great afternoon:)
If you would like to rewrite 3 * x + 4 * y = 10 using function notation, you can do this using the following steps:
3 * x + 4 * y = 10
4 * y = 10 - 3 * x /4
y = 10/4 - 3/4 * x
y = 5/2 - 3/4 * x
The correct result would be y = 5/2 - 3/4 * x.
