Step-by-step explanation:

perimeter is given by

p=2L +2W

but from the expression;The length is 4 m more than the twice the width

is written as L =4+2W

putting it in the formula

p= 2(4+2W) +2W

but perimeter was given as 44m

44= 8+4w+2w

44=8+6w

44-8=6w

36=6w

dividing through by 6

w=36/6

w=6m

thus, the width is 6m

put it in the expression L =4+2W to get the length

L =4+2(6)

L=4+12

L=16m

thus the length is 16m

What is the slope of the line through (-4.2) and (3,-3)?

Dennis_Churaev [7]

Finding the slope using the two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =-3\\y_{1} =2\\x_{2} =3\\x_{1} =-4$

^^^Plug these numbers into the formula for slope...

$\frac{-3-2}{3 - (-4)}$

$\frac{-5}{7}$

^^^This is your slope

Hope this helped!

I will Give BRAINLIEST p^2–16c^2–p–4c

IgorLugansk [536]

Answer:

(p + 4c)(p - 4c - 1)

Step-by-step explanation:

p² - 16c² - p - 4c

p² - (4c)² - (p + 4c)

(p - 4c)(p + 4c) - (p + 4c)

(p + 4c)(p - 4c - 1)

On a certain map 2.5 inch represents 15 miles Bay seed City in Greenwood are four inches apart on the map what is the actual dis

rodikova [14]

The first step to solving this would be to determine how many miles are represented by 1 inch:
15/2.5 = 6
1 inch = 6 miles
Now we want to know how far 4 inches is in miles:
6*4 = 24
Greenwood and Bay City are 24 miles apart

Hope this helps (also please mark me brainliest I only need 1 more to rank up)

Heights for women are bell-shaped with a mean of 65 inches and standard deviation of 2.5 inches. If a random sample of 16 women

loris [4]

Answer:

μ= 65 inches; σ= 0.625 inch

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed(bell-shaped) random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

$\mu = 65, \sigma = 2.5$

By the central limit theorem, the sample of 16 will have:

$\mu = 65, \sigma = \frac{2.5}{\sqrt{16}} = 0.625$

So the correct answer is:

μ= 65 inches; σ= 0.625 inch
