Answer:
Step-by-step explanation:
I(x)=P(13x) = 2(13x)²+3(13x) +4
I(x)=P(13x).= 338x²+39x+4
Answer:
Step-by-step explanation:
4(y+7)=4(y)+4(7)
=4y+28
it would be a ratio5:6
Step-by-step explanation:
80, 80, 80, 80, 80, 85, 85, 85, 85, 85, 90, 90, 90, 90, 90
Mean = 85
Median = 85
Range = 10
Mean Absolute Deviation (MAD) = 3.33
So:
Let us simply the parenthesis first.
So we have

We can rearrange the terms and get:

Which is equal to

So now we have to complete it by multiplying it all by 1/4 which is basically dividing it by 4.
So:

Simplifying that, we get:

And reducing that farther we finally get:

Which is your final answer :)
