The mean is 4.93333 (3 is repeating)
Explanation
So mean is just the sum of the numbers divided by the number of terms
So we would solve this by adding up all terms as shown here
10.6 + 4 + 4 + 6 + 4 + 1 = 29.6 = sum
Then we will divide the sum by the number of terms which is 6 in this case to get our mean as shown here
29.6 / 6 = 4.9333
The mean is 4.9333 (3 is repeating)
Since the painting is hung in center of a rectangular wall ,the distance between them on either side will be the same.so we can divide the length of the painting and wall by 2.we will get 2.4/2=1.2 feet and 20/2=10 feet .10-1.2=8.8 feet gives the distance between the right edge of the painting and right edge of the wall
Answer:20

Answer:
15.87% probability that the car travels more than 53 miles per gallon.
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:

Find the probability of the following events: A. The car travels more than 53 miles per gallon. Probability
This is the pvalue of Z when X = 53. So



has a pvalue of 0.8413
1 - 0.8413 = 0.1587
15.87% probability that the car travels more than 53 miles per gallon.
