Answer: Width is 7 inches, length is 15 inches.

Step-by-step explanation:

Let the width be w. Then, the length is w+8.

$2(w+w+8)=44\\\\w+w+8=22\\\\2w+8=22\\\\2w=14\\\\w=7\\\\\implies l=15$

Hey there! I'm happy to help!

If you raise a fraction to an exponent, you apply that exponent to the numerator and the denominator. This would give us $\frac{y^4}{x^4}$ .

Have a wonderful day! :D

NEED THIS DONE ASAP<br><br><br> If P(x) = -2(1 - x)2 +5, what is the value of<br> P(-3)?

marusya05 [52]

Answer:

P(-3) = -1

Step-by-step explanation:

So just substitute the value of x in the equation:

Value of x is (-3)

So:

P(x) = -2(1 - x)2 +5

P(-3) = -2(1-(-3)) 2 + 5

P(-3) = -2(4) 2 + 5

P(-3) = -8 + 2 + 5

P(-3) = -6 + 5

P(-3) = -1

Answer:

y = 3x - 5

Step-by-step explanation:

So first take any two points from the graph.

(0, -5), (2, 1)

The slope is $\frac{1 + 5}{2 - 0} =3$

y = mx + b

b is the y intercept

The y intercept is (0, -5) as this is where the line intersects the y axis.

y = 3x - 5

The number of showtimes for one movie over several days is shown. What is the mean absolute deviation (MAD)? 9, 6, 8, 9, 7, 4, 3

velikii [3]

Given:

The data set is:

9, 6, 8, 9, 7, 4, 3, 5, 2, 4

To find:

The mean absolute deviation (MAD) of the given data.

Solution:

We have,

9, 6, 8, 9, 7, 4, 3, 5, 2, 4

The mean of the given data set is:

$\overline{x}=\dfrac{1}{n}\sum x_i$

$\overline{x}=\dfrac{1}{10}(9+6+8+9+7+4+3+5+2+4)$

$\overline{x}=\dfrac{1}{10}(57)$

$\overline{x}=5.7$

So, the mean of the given data set is 5.7.

The mean absolute deviation (MAD) is:

$MAD=\dfrac{1}{n}\sum |x-\overline{x}|$

The mean absolute deviation (MAD) of the given data is:

$MAD=\dfrac{1}{10}(3.3+0.3+2.3+3.3+1.3+1.7+2.7+0.7+3.7+1.7)$

$MAD=\dfrac{1}{10}(21)$

$MAD=2.1$

Therefore, the mean absolute deviation (MAD) of the given data set is 2.1.
