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

dimaraw [331]

Answer: MP=(1,1)

Step-by-step explanation:

MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})

MP= (\frac{-2+4}{2})(\frac{-3+5}{2}) -2+4=2  -3+5=2

MP= (\frac{2}{2})(\frac{2}{2}) 2/2=1
