Which simplified ratio correctly compares 30 inches to 2 feet?

Serggg [28]

Answer:

5:4

Step-by-step explanation:

There are 12 inches in one foot, so there are 24 inches in 2 feet.

Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.

This is

$30\ :\ 24$

Simplify it:

$30\ :\ 24=\dfrac{30}{24}=\dfrac{6\times 5}{6\times 4}=\dfrac{5}{4}=5\ :\ 4$

Bobby calculates the mean number of goals for each of the players on a hockey team in the set {4, 7, 5, 8, 12, 2, 3, 5, 7}. Dete

katrin [286]

Answer:

2.3

Step-by-step explanation:

n = Number of data points = $9$

The data set is

$4, 7, 5, 8, 12, 2, 3, 5, 7$

Mean

$\bar{x}=\dfrac{4+7+5+8+12+2+3+5+7}{9}=5.89$

Absolute mean deviation

$\dfrac{|4-5.89|+|7-5.89|+|5-5.89|+|8-5.89|+|12-5.89|}{9}\\+\dfrac{|2-5.89|+|3-5.89|+|5-5.89|+|7-5.89|}{9}=2.3$

The mean absolute deviation of the data set is $2.3$ .

Mr. Starnes wondered what proportion of Katy Perry's Twitter followers are

Citrus2011 [14]

Answer and Step-by-step explanation:

To calculate a confidence interval for a proportion:

1) Determine the proportion

$p=\frac{308}{500}$

p = 0.616

2) A 90% confidence interval has z-score that is 1.645.

3) Calculate margin of error

$ME=\sqrt{\frac{p(1-p)}{n} }$

where

n is the sample size

$ME=\sqrt{\frac{0.616(1-0.616)}{500} }$

$ME=\sqrt{\frac{0.616(0.384)}{500} }$

ME = 0.02175

Then the interval is given by

p ± z(ME)

0.62 ± 1.645(0.02175)

0.62 ± 0.035

The interval will be

0.585 < p < 0.655

What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.
