From the figure associated to your question (which you did not attach), Amy's median is 40 and Megan's median is 35.

Thus, the difference in medians is given by 40 - 35 = 5.

From the figure, Megan's Q1 is 25 and her Q3 is 40, thus her interquatile range is given by Q3 - Q1 = 40 - 25 = 15.

Therefore, the difference of the medians as a multiple of Megan's interquartile range is given by

Difference in medians = 1/3 (Megan's IQR)

Rectangle A has a length of 2x + 6 and a width of 3x. Rectangle B has a length of x + 2 and an area of 12 square units greater t

Maurinko [17]

So here is how you solve for the answer.
Firstly, you solve for the Area of Rectangle A.
The formula for Area is Length x width.
So A = (2x + 6)(3x) and the result is: 6x^2 + 18x
Now, let y be the width of rectangle B.
(x+2) (y) = 6x^2 + 18x + 12
(x+2) y = 6(x+1)(x+2)
y = 6(x+1)
So the final answer would be width is 6x + 6. The answer is the third option. Hope this answer helps.

What is BC ? Enter your answer in the box. units

Vladimir79 [104]

Answer:

BC = 25

Step-by-step explanation:

AB = AC since it is an isosceles triangle

4x+1 = 2x+23

subtract 2x from each side

4x-2x+1 = 2x-2x+23

2x +1 = 23

subtract 1 from each side

2x+1 -1 = 23-1

2x = 22

divide by 2

2x/2 =22/2

x =11

BC = 3x-8

BC = 3(11) -8

BC =33-8

BC = 25

Let f(x)=3x-6. Is f one-to-one? If it is find f^-1, if not explain why.

beks73 [17]

Answer: Yes, $\bold{f^{-1}(x)=\dfrac{x+6}{3}}$

Step-by-step explanation:

f(x) = 3x - 6 is a line so it is a function because

it passes the vertical line test

and the horizontal line test

To find the inverse, swap the x's and y's and solve for y

$y=3x-6\\\\\\\text{Swap the x's and y's:}\qquad x=3y-6\\\\\text{Add 6 to both sides:}\qquad x+6=3y\\\\\text{Divide both sides by 3:}\qquad \dfrac{x+6}{3}=y$
