Answer:

$v=\frac{145}{8}$

Step-by-step explanation:

$\frac{5}{v}=\frac{2}{7.25}$

$\frac{5}{v}=\frac{2}{\frac{725}{100}}$

$v=\frac{2}{\frac{5^2*29}{2^2*5^2}}$

$v=\frac{145}{8}$

Find the perimeter of rectangle MNOP with vertices M(-2,-5) N (-2,-4) O(3,-4) and p (3,5)

Vadim26 [7]

Answer:

I'm assuming p is (3, -5) since M is (-2, -5) if so, then the perimeter should be 16.

7th Grade Unit IV Performance Task (Proportional Relationships - Produce Stands)

White raven [17]

Al's and Barbara's produce stands are illustrations of proportional relationships

The unit rate at Al’s Produce Stand is 0.25, and the unit rate at Barbara’s Produce Stand is 0.24
The equation at Al’s Produce Stand is y = 0.25x, and the equation at Barbara’s Produce Stand is y = 0.24x

<h3>Step 1: The constant of proportionality</h3>

From the question, we have the following ordered pairs

Al’s Produce Stand: (x, y) = (6,1.50)
Barbara’s Produce Stand: (x, y) = (13,3.12)

The unit rate is calculated as:

$k = \frac yx$

So, we have:

$k = \frac{1.50}{6}$

$k = 0.25$

<u>Barbara</u>

$k = \frac{3.12}{13}$

$k = 0.24$

Hence, the unit rate at Al’s Produce Stand is 0.25, and the unit rate at Barbara’s Produce Stand is 0.24

<h3>Step 2: The equation</h3>

This is represented as

$y = kx$

So, we have:

$y = 0.25x$

<u>Barbara</u>

$y = 0.24x$

Hence, the equation at Al’s Produce Stand is y = 0.25x, and the equation at Barbara’s Produce Stand is y = 0.24x

<u>Step 3: The missing values</u>

This cannot be determined, as the table is not properly formatted

Suppose that weekly income of migrant workers doing agricultural labor in Florida has a distribution with a mean of $520 and a s

Finger [1]

Answer:

$z=\frac{510-520}{\frac{90}{\sqrt{100}}}= -1.11$

And we can find the probability using the normal standard distribution table and with the complement rule we got:

$P(z$

Step-by-step explanation:

For this problem we have the following parameters:

$\mu = 520, \sigma = 90$

We select a sample size of n =100 and we want to find this probability:

$P(\bar X$

The distribution for the sample mean using the central limit theorem would be given by:

$\bar X \sim N(\mu,\frac{\sigma}{\sqrt{n}})$

And we can solve this problem with the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And if we find the z score formula we got:

$z=\frac{510-520}{\frac{90}{\sqrt{100}}}= -1.11$

And we can find the probability using the normal standard distribution table and with the complement rule we got:

$P(z$
