Olin [163]

Solution: We are given:

ACT scores follow normal distribution with \mu=20.9,\sigma =4.8

SAT scores follow normal distribution with \mu=1026,\sigma=209

Now, let's find the z score corresponding to Joe's SAT score 1351.

z=\frac{x-\mu}{\sigma}

        =\frac{1351-1026}{209}

        =\frac{325}{209}

        =1.56

Therefore, Joe's SAT score is 1.56 standard deviations above the mean.

Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.

Therefore, we have:

z=\frac{x-\mu}{\sigma}

1.56=\frac{x-20.9}{4.8}

1.56 \times 4.8 = x - 20.9

7.488=x-20.9

x=20.9+7.488

x=28.388 \approx 28.4

Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4

Answer:$3,700

Step-by-step explanation:

Gross sales are the total amount of sales a company earned throughout a specific period of time, without taking into consideration any costs involved with running a business. Gross sales do not factor in expenses related to running a business, also known as cost of goods sold (COGS), which get deducted when calculating net sales. For example, they do not account for costs associated with item production, employee wages, building rent, returns, theft or sales tax.

Gross Sales = $3,700
