Answer:

19.5 cm

Step-by-step explanation:

The median of a data set is the middle number. It can be easily found by crossing out the first value then the ending value, and you keep repeating that pattern. However, in this case, when we cross them out, we're left with the numbers 18 and 21. When we come across a problem like this, we find the mean of 18 and 21 by adding them up and then dividing them by 2. 18 + 21 is 39, and 39/2 is 19.5.

Therefore, the answer is 19.5 cm.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

What is the rate of change of the linear function that passes through the points (1, 0) and (0, -3)

melisa1 [442]

Answer:

Step-by-step explanation:

To find the rate of change we: divide the change in y (output) by the change in x (input).

A = (-3 - 0) / (0 - 1) = -3 / -1 = 3

W(x)=9x+8,evaluate w(5)

natima [27]

Use the substitution method

w(x)=9x+8

w(5)=9(5)+8

Do the parenthesis first then add because of using PEMDAS

P= Parentheses

E= Exponents

M= Multiplication

D= Division

A= Addition

S= Subtraction

45+8

=53

Answer: w(5)=53

Factor completely and then place the factors in the proper location on the grid a^2-a-20

Gnoma [55]

Answer:

$(x-5)(x+4)$

Step-by-step explanation:

We have the following quadratic equation

$a^2-a-20$

The factored expression will have the following form

$(x+b)(x+c)$

Where b and c are two real numbers which when added together result in -1, and multiplying them results in -20

$b*c=-20\\b+c=-1$

You can verify that the numbers that meet this condition are:

-5 and 4

Then the factors are:

$(x-5)(x+4)$

What is the constant rate of change from the graph?

Harlamova29_29 [7]

Answer:

$5$

Step-by-step explanation:

When looking for constant rate, you have to see what is the repeating rate or coordinate in order to solve constant rate.

Let us take two coordinate points,

( 1 , 5 )
( 3 , 15 )

If we were to look for constant rate, we have to see the similarity (in this case the multiplication of the two numbers) between the two points.

What can they be?

They both have x multiplying by 5 to get y!

1 * 5 = 5

3 * 5 = 15

The same goes with all other points on the graph, leaving you with five as the constant rate.
