Answer: 21p^2 + 3qp

Explanation:

To find the area of the triangle you have to do LxHx1/2

Length = 7p+q

Height = 6p

(7p+q)*6p*1/2 = 21p^2+3qp

I hope this helped!

A rectangle has a fixed perimeter of 350 but the length and width of the rectangle can vary. Define a function g that determines

Verdich [7]

Answer:

g(L) = 175L - L²

Step-by-step explanation:

350 = 2(length + width)

length + width = 175

Let L be the length,

L + width = 175

width = 175 - L

Area = length × width

g(L) = L(175 - L)

g(L) = 175L - L²

Using the normal distribution, it is found that:

a) The pilot is at the 72th percentile.

b) 19.13% of pilots are unable to fly.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 72.6, \sigma = 2.7$ .

Item a:

The percentile is the <u>p-value of Z when X = 74.2</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{74.2 - 72.6}{2.7}$

Z = 0.59

Z = 0.59 has a p-value of 0.7224.

72th percentile.

Item b:

The proportion that is able to fly is the <u>p-value of Z when X = 78 subtracted by the p-value of Z when X = 70</u>, hence:

X = 78:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{78 - 72.6}{2.7}$

Z = 2

Z = 2 has a p-value of 0.9772.

X = 70:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{70 - 72.6}{2.7}$

Z = -0.96

Z = -0.96 has a p-value of 0.1685.

0.9772 - 0.1685 = 0.8087 = 80.87%.

Hence the percentage that is unable to fly is:

100 - 80.87 = 19.13%.

Nancy was trying to save up $457. At her job she made $8 an hour and she worked 40 hours a week. After paying for her food and o

Aloiza [94]

So if she makes 8 and hour and works 40 hours a week
Thats 320 take home every week
Now divide that number by 8 as she is only taking home 1/8th and you are left with only 40 dollars saved a week.
Meaning to get to 457 it would take 11.425 weeks of work

The equation of a line y = 5x + q passes through (2,11) Find the value of q

ra1l [238]

Answer:

There is an infinite number of lines that pass through the point (2, 11). Therefore, there is an infinite number of equations. To define a single line, you must have at least two points. One point is not enough.
