3+5=8
8^2 is 8×8 which equals 64.
The square of the sum of 3 and 5 equals 64.
The volumes will be the same, because the heights are equal and the cross-sectional areas at every level parallel to the bases are also equal.
Answer:
22.29% probability that both of them scored above a 1520
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

The first step to solve the question is find the probability that a student has of scoring above 1520, which is 1 subtracted by the pvalue of Z when X = 1520.
So



has a pvalue of 0.5279
1 - 0.5279 = 0.4721
Each students has a 0.4721 probability of scoring above 1520.
What is the probability that both of them scored above a 1520?
Each students has a 0.4721 probability of scoring above 1520. So

22.29% probability that both of them scored above a 1520
The answer is A because that information they gave to you
The surface area<span> of a right </span>prism<span> can be calculated using the following formula: SA 5 2B 1 hP, where B is the </span>area<span> of the base, h is the height of the </span>prism<span>, and P is the perimeter of the base. The </span>lateral area<span> of a figure is the </span>area<span> of the non-base faces only.</span>
