Answer:
The interval that would represent the middle 68% of the scores of all the games that Riley bowls is (147, 173).
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 160, standard deviation of 13.
Middle 68% of the scores of all the games that Riley bowls.
Within 1 standard deviation of the mean, so:
160 - 13 = 147.
160 + 13 = 173.
The interval that would represent the middle 68% of the scores of all the games that Riley bowls is (147, 173).
The answer to the question
Answer:
1/95
Step-by-step explanation:
2 5/7 = 19/7
1/35 divided by 2 5/7
1/35 ÷ 19/7
1/35 × 7/19
1 × 7/35 × 19
7/665 = 1/95
Answer:
Step-by-step explanation:
Piece of land:
Length = l = 10 m & width = w = 8 m
Area of land = l*w
= 10 * 8
= 80 square meter.
Flower bed:
Side = 2 m
Area of one square flower bed = side * side = 2 *2 = 4 square meter
Area of 5 flower bed = 5 *4 = 20 sq.m
Area of the remaining land = Area of piece of land - area of 5 flower bed
= 80 - 20
= 60 sq. m
Answer:24
