Find the height of a cylinder that has a radius of 5 m and a volume of 450 mº.

Answers

Answer 1

Answer:

The height of cylinder is 5.73 meters.

Further explanation:

Given

$Volume\ of\ cylinder=V=450\ m^3\nRadius=r=5\ m$

The formula for calculating volume of cylinder is:

$V=\pi r^2h$

Putting the values of volume, radius and pi

$450=3.14*(5)*h\n450=3.14*25*h\n450=78.5*h\nh=(450)/(78.5)\nh=5.73\ meters$

The height of cylinder is 5.73 meters.

18. In their last basketball game, Holly scored25 points and Juanita scored 16 points. The
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.
