Step-by-step explanation:

A linear function is described as:

https://tex.z-dn.net/?f=f(x)%20%3D%20ax%20%2B%20b

When the value of x = 0, then you're left with

Answer-

Explanation:

Mode- the number that appears the most

15 was a number that appeared the most and the reason it’s not the first one you picked is because the middle numbers you end up with are 18 and 20.

Subtract the sum of three test scores from the product of 75 and 5 .
I think

Answer:

Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.

Step-by-step explanation:

From the question:

100, 70, 85 on three of her five tests

Total number of test = 5

mean of the five scores is 75

mean = average of the five scores

Average score = Total score / total number of test

Total score = Average score * total number of test

= 75*5 =375

to find remaining two tests' scores

Total score - the 3 scores from question

= 375 - 100 - 70 - 85

=120

If u want to find the score of each of the unknown test

From question:

She could not remember the other two scores, which were the same.

Thus,

The score of one test

= 120/ 2

=60

Because the radius is 4.5 inches we use the area formula for a circle ( pi * radius squared) to find the answer so

4.5 * 4.5 * 3.14 which will equal 63.585 inches squared

Hope this helps

Answer:

D. 4.5

The Area is 63.585

Step-by-step explanation:

So the diameter is twice the size of the "r" or radius so divide 9 by 2

which is 4.5

The formula for a circle is πr^2

4.5 times itself is 20.25

times pi or 3.14 is 63.585

If the area of each tile is 1 square inch, how many tiles will he need?
