A recipe calls for 2 1/3 cups of flour, cups of white sugar, and cups of brown sugar. The recipe makes 6 servings.

Tems11 [23]

Answer:

Lets find how much flour we need for just one serving.

2 2/3 ÷ 6

8/3 ÷ 6

8/3 * 1/6

8/18

4/9 cup of flour per serving

If we triple the recipe (6 * 3 = 18), we will have a total of 18 servings. Multiply the amount of flour we got for one serving to 18 servings.

4/9 * 18/1

72/9

8 cups of flour for 18 servings

Best of Luck!

Majesty Video Production Inc. wants the mean length of its advertisements to be 24 seconds. Assume the distribution of ad length

oksano4ka [1.4K]

Answer:

It is going to be bell-shaped(normally distributed), with mean $\mu = 24$ and standard deviation $s = \frac{2}{\sqrt{15}} = 0.5164$ .

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .
