im not for sure but I think the answer is 9! my reasoning is below,,

Step-by-step explanation:

\frac{49}{7}  =  \frac{63}{x}

do the crossing method and it would result in this

(49×x) = (63×7)

after simplifying both sides

49x = 441

divide both sides by 49 and the result will be

x = 9 !!

A soft drink machine outputs a mean of 27 ounces per cup. The machine's output is normally distributed with a standard deviation
Rzqust [24]

Answer:  0.6065

Step-by-step explanation:

Given : The machine's output is normally distributed with

\mu=27\text{ ounces per cup}

\sigma=3\text{ ounces per cup}

Let x be the random variable that represents the output of machine .

z-score : z=\dfrac{x-\mu}{\sigma}

For x= 21 ounces

z=\dfrac{21-27}{3}\approx-2

For x= 28 ounces

z=\dfrac{28-27}{3}\approx0.33

Using the standard normal distribution table , we have

The p-value : P(21

P(z

Hence, the probability of filling a cup between 21 and 28 ounces=  0.6065
