In a recent national survey, the mean price for a 2000 sq ft home in Florida is $240,000 with a standard deviation of $16,000. T
Doss [256]

Answer:

In both Florida and Ohio the house is 2.5 standard deviations from the mean.

Step-by-step explanation:

Z-score

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem:

The 200,000 house would be closer to the mean in the state in which the absolute value of the z-score is smaller.

Florida:

\mu = 240000, \sigma = 16000

So

Z = \frac{X - \mu}{\sigma}

Z = \frac{200000 - 240000}{16000}

Z = -2.5

In Florida, a home priced at $200,000 is 2.5 standard deviations from the mean.

Ohio:

\mu = 170000, \sigma = 12000

So

Z = \frac{X - \mu}{\sigma}

Z = \frac{200000 - 170000}{12000}

Z = 2.5

In Ohio, it is also 2.5 standard deviations from the mean.

In both Florida and Ohio the house is 2.5 standard deviations from the mean.

Solve for x, and refer to the attached image.
AVprozaik [17]

Answer:

x=8

Step-by-step explanation:

7+5x

so basically what you have to do is take the 7 and subtract from both sides

so like this: 7-7 is 0 so that cancels then 47-7 is 40

then you take 5x and divide 40 by 5

so x=8

hope this helped!
