You need $315 worth of sales, if I'm right. $100-30 is $70. 70/x=2/9. 70x9=630/2=315.

Everyday day you make $30 -plus- 2/9th of your sales.
1)To convert a fraction into a percentage decimal you divide the numerator by the denominator:
2 divided by 9= .22 = 22%

in turn, you earn $30 plus 22% of your sales.

to figure out what dollar amount OF SALES (only)go you need to earn $100. you have to subtract 22% out of $100 and also subtract the $30you automatically make because it only asks for the dollar amount of sales. therefore:
-to get 22% out of a 100 you multiply:
100*.22= 22
100-22=78
78-30=48.

total dollar amount of sales needed to earn $100 is: $48.

IQ scores are normally normally distributed with a mean of 100 and center deviation of 15 if one person is randomly selected wha
Arlecino [84]

Answer:

22.86% probability that the persons IQ is between 110 and 130

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

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, we have that:

\mu = 100, \sigma = 15

If one person is randomly selected what is the probability that the persons IQ is between 110 and 130

This is the pvalue of Z when X = 130 subtracted by the pvalue of Z when X = 110.

X = 130

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

Z = \frac{130 - 100}{15}

Z = 2

Z = 2 has a pvalue of 0.9772

X = 110

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

Z = \frac{110 - 100}{15}

Z = 0.67

Z = 0.67 has a pvalue of 0.7486

0.9772 - 0.7486 = 0.2286

22.86% probability that the persons IQ is between 110 and 130
