Answer:

$P = 4\sqrt{13}$

Step-by-step explanation:

Given

$W = (7, 2)$

$X = (5, -1)$

$Y = (3, 2)$

$Z =(5, 5)$

Required

The perimeter

To do this, we first calculate the side lengths using distance formula

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2$

So, we have:

$WX = \sqrt{(5- 7)^2 + (-1 - 2)^2$

$WX = \sqrt{13}$

$XY = \sqrt{(3-5)^2 + (2--1)^2}$

$XY = \sqrt{13}$

$YZ = \sqrt{(5-3)^2 + (5-2)^2}$

$YZ = \sqrt{13}$

$ZW = \sqrt{(7 - 5)^2 + (2 - 5)^2}$

$ZW = \sqrt{13}$

The perimeter is:

$P = WX + XY + YZ + ZW$

$P = \sqrt{13}+\sqrt{13}+\sqrt{13}+\sqrt{13}$

$P = 4\sqrt{13}$

Afirm’s marketing manager believes that total sales X can be modeled using a normal distribution with mean m ¼ $2.5 million and

Ugo [173]

Answer: 0.0475

Step-by-step explanation:

Given : A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.

Where , Population mean : $\mu=2.5\text{ million}=2.5\times1000000=2500000$

Standard deviation : $\sigma=300000$

To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.

∵ $z=\dfrac{x-\mu}{\sigma}$

Then , for x= 3,000,000

$z=\dfrac{3000000-2500000}{300000}=1.67$

Then , the probability that the firm’s sales will exceed $3 million is given by :-

$P(z>1.67)=1-P(z$

Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
