Answer:
the units were only misalignes by a few cm
Answer:
I think it's B
Step-by-step explanation:
His average speed per minute is 1,448 meters per minute, and there are 60 minutes in a single hour. You would multiply 1,448 by 60 to get the answer of 86,880 meters per hour.
Answer:
Area under the normal curve: 0.6915.
69.15% probability of putting less than 24 ounces in a cup.
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:

You have been asked to calculate the probability of putting less than 24 ounces in a cup.
pvalue of Z when X = 24. So



has a pvalue of 0.6915
Area under the normal curve: 0.6915.
69.15% probability of putting less than 24 ounces in a cup.
Answer:
n = 5
Step-by-step explanation:
Given
5n + 20n = 5(n + 20), that is
25n = 5(n + 20) ← divide both sides by 5
5n = n + 20 ( subtract n from both sides )
4n = 20 ( divide both sides by 4 )
n = 5
