The mean cost of a 5 pound bag of shrimp is $50 with the standard deviation of six dollars. If a sample of 40 bags of shrimp is

Lemur [1.5K]

SOLUTION

We will use the formula

$\begin{gathered} Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}} \\ where\text{ } \\ x=51.3,\mu=50,\sigma=6,n=40 \end{gathered}$

Applying we have

$\begin{gathered} Z=\frac{51.3-50}{\frac{6}{\sqrt{40}}} \\ Z=\frac{1.3}{\frac{6}{\sqrt{40}}} \\ Z=1.37032 \end{gathered}$

Now using a Zscore calculator for 1.370320, we have

the vertices of a feasible region are (1,0) (5,5) and (5,0) . what is the maximum value of the function P=2x-y?

wariber [46]

The maximum value of the function is 10

<h3>How to determine the maximum value?</h3>

The function is given as:

P = 2x - y

The feasible regions are given as:

(1,0), (5,5) and (5,0)

Substitute these values in P = 2x - y

P = 2(1) - 0 = 2

P = 2(5) - 5 = 5

P = 2(5) - 0 = 10

The maximum value in the above computation is 10

Hence, the maximum value of the function is 10
