1. the mean is 16
2. the mean is 22.5
the formula that can be used to calculate the mean is
= sum of terms/number of terms
for the first question the mean can be calculated as follows
sum of terms= 20+15+19+16+10
= 80
number of terms= 5
mean= 80/5
= 16
for the second question the mean can be calculated as follows
sum of terms= 19+23+11+30+27+27+22+26+16+24
= 225
number of terms= 10
mean= 225/10
= 22.5
Hence the mean for the first expression is 16 and the mean for the second expression is 22.5

Answer: the hundreds place
Answer:
Step-by-step explanation:
We have
and
We want to find (f+g)(x).
By the algebraic properties of polynomial functions,
This simplifies to
We can't simplify further, hence the simplest form
Answer:
(x+3)/(x-4)
Step-by-step explanation:
[2x²/(x-4)(x-3)] - [x²+9/(x-4)(x-3)] =
(x²-9)/(x-4)(x-3) =
(x+3)(x-3)/(x-4)(x-3) =
x+3/x-4
Answer:
<h2>4</h2>
Step-by-step explanation:
Now if the 2 at the end is an power then it will turn to
So the answer will be 4.
