Step-by-step explanation:
First step is to turn the 80% into a decimal. So place a decimal twice to the left to make it .80. Then, multiply 20 by .80. Upon that, you get your answer.
mean number of points Holly scores is 20 with
a standard deviation of 2. The mean number
of points Juanita scores is 12 with a standard
deviation of 1.25. Whose score is better relative
to her average number of points per game?
Answers
Answer:
Juanita's score was better
Step-by-step explanation:
Juanita scored 6.4 points above her average score whereas Holly only scored 2.5 points above her average score. (this was calculated via z-scores)
Final answer:
To find who performed better relative to their average, we calculated the z-scores of both players. Juanita's score was 3.2 standard deviations above her mean, whereas Holly's was 2.5 standard deviations above her mean, making Juanita's performance relatively better.
Explanation:
To answer this question, we need to find how many standard deviations each player's score deviates from their respective means. This is referred to as the z-score. The z-score is calculated using the formula (X - μ) / σ, where X is the score, μ is the mean score and σ is the standard deviation.
For Holly, her z-score would be (25 - 20) / 2 = 2.5. This means Holly's score was 2.5 standard deviations above her mean score.
For Juanita, her z-score would be (16 - 12) / 1.25 = 3.2. This means Juanita's score was 3.2 standard deviations above her mean score.
Since Juanita's z-score is higher than Holly's, Juanita's score is better relative to her average number of points per game.

Answer: 120 pieces.
Step-by-step explanation:
We know that 1 yard = 36 inches
Given: The length of each piece of ribbon= 25 yards
If she needs to cut 22 inches long pieces, then the total number of pieces cut from 1 ribbon
Thus, the total number of pieces she cut from 3 ribbons
Hence, the greatest number of 22-inch pieces that she can cut from the three ribbons =120

Area = length * width
Since width = 1/5 length
Area = length * 1/5 length
Area is 9/20 square mile,
9/20 square mile = 1/5 * square length
Square length = 9/4 square mile
Length = 3/2 mile
