Answer:
3(6)(4) = 72 cm
Step-by-step explanation:
The volume of a rectangular prism = Length * Width * Height
Substitute your values into the equation and solve for V
V = 3 * 6 * 4
V = 72

Answer:
10.57% probability that the mean contents of the 625 sample cans is less than 9.995 ounces.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
Normal probability distribution
Problems of normally distributed samples can be 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:
What is the probability that the mean contents of the 625 sample cans is less than 9.995 ounces?
This is the pvalue of Z when X = 9.995. So
has a pvalue of 0.1057
So there is a 10.57% probability that the mean contents of the 625 sample cans is less than 9.995 ounces.
