vaieri [72.5K]

Answer:

6

Step-by-step explanation:

Profit is revenue minus cost.

P(x) = R(x) − C(x)

P(x) = 28x − (7x + 117)

P(x) = 21x − 117

When the profit is 0, the value of x is:

0 = 21x − 117

21x = 117

x = 5.6

Rounding up to the nearest integer, the company starts to turn a profit at 6 milkshakes.

sesenic [268]

Answer:  b. 1.94

Step-by-step explanation:

For binomial distribution model , the formula to find standard deviation is given by :-

\sigma=\sqrt{np(1-p)}

Given : The portability that the offices she visits will eventually purchase her product: p=0.25

The number of offices she visited = 20

We assume that the binomial is an appropriate model for the number of offices that make a purchase.

Then, to find the distance of  the possible number of sales Tina could observe from the overall mean number of sales we find standard deviation.

\sigma=\sqrt{np(1-p)}\\\\=\sqrt{20(0.25)(0.75)}\\\\=\sqrt{3.75}=1.9364916731\approx1.94

Hence, the correct answer is option (b).
