Answer:
95%
Step-by-step explanation:
Given that in a large class, students' grade in a test followed the normal distribution.
The normal distribution is symmetric about the mean, bell shaped and having area of more than 99% between 3 std deviations from the mean on either side.
We are to find the percent of grades is between two standeard deviation below the mean and two standar deviation above the mean (that is in between Xbar-2S and Xbar+2S grades)
where x bar is the mean and s = std devition
This is equivalent to 100*Prob that X lies between these two values
As per normal distribution curve 68, 95, 99 rule we get
approximately 95% lie between these two values.

a). Area = (length) (width)
= (60 ft) (√18 ft)
= (60 √18) ft²
= 60 √(9 · 2) ft²
= 60 (3) √2 ft²
= 180 √2 ft² (about 254.6 ft²)
b). Volume = (length) (width) (height)
= (60 ft) (√18 ft) (√10 ft)
= 60 √(180) ft³
= 60 √(4 · 9 · 5) ft³
= 60 (2) (3) √5 ft³
= 360 √5 ft³ (about 805 ft³)

Answer: 91</h3>
========================================================
Explanation:
The observations are in ascending order, which means the set is sorted from smallest to largest.
The X is at the right-most endpoint, so X is the largest value (aka the max).
The min is 33, so,
max - min = range
X - 33 = 58
X = 58+33
X = 91 is the max
Answer:
Below.
Step-by-step explanation:
In total there are 8 kids. Each cupcake is 2.75 so 8x2.75= 22 now the total is 46.00 So? 46-22 = 24. 24 divided by 2 = 12.
I Divided by 12 because they said cost of each individual cookie.
