Answer:

12 inches

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well to solve the given question we need to use fractions,

if 1 inch is 20 milles, we can set up the following.

\frac{1}{20} = \frac{x}{240}

Cross multiply

240 = 20x

Divide both sides by 20

x = 12

So it is 12 inches in the map.

<em>Hope this helps :)</em>

The mean annual tuition and fees for a sample of 12 private colleges was 36,800 with a standard deviation of 5,000 . A dotplot s
Ilya [14]

Answer:

The value of the test statistic and degrees of freedom is 2.148 and 11 respectively.

Step-by-step explanation:

Consider the provided information.

The mean annual tuition and fees for a sample of 12 private colleges was 36,800 with a standard deviation of 5,000 .

Thus, n = 12, \bar x=36800 σ = 5000

degrees of freedom = n-1 = 12-1 = 11

H_0: \mu = 33700\ and\ H_a: \mu \neq 33700

Formula to find the value of z is: z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}

Where \bar x is mean of sample, μ is the mean of population, σ is the standard deviation of population and n is number of observations.

z=\frac{36800-33700}{\frac{5000}{\sqrt{12}}}

z=2.148

Hence, the value of the test statistic and degrees of freedom is 2.148 and 11 respectively.

boris currently has $1200 in his saving account.. he saves$25 per month.he saves the same amount each month and does no take any
Setler [38]
10 months. First you subtract what is already in possession from what they need: $1450-$1200= $250    Then you would divide how much money is left to earn by how much money is gained every year:  $250 divided by $25= 10 months    Hope this helps!!
