Answer:
m+n=23
Step-by-step explanation:
the modes m and n have to be data points more than 1 time, but equal
if there are 7 data points, then there are 4 unknown left/2 2 each
(2m-3+m+12+3n+2+m+m+n+n)/7=18
(3m+9+3n+2+m+m+n+n)/7=18
(5m+5n+11)/7=18
(5/7)*m+(5/7)*n+11/7=126/7
(5/7)*m+(5/7)*n=115/7
5m+5n=115
m+n=115/5
m+n=23

<u><em>Answer:</em></u>7
<u><em>Explanation:</em></u><u>We are given the equation:</u>
</span>

<span> * c
We want to get the value of the equation at <u>c = 8</u>.
Therefore, all we have to do is <u>substitute c in the equation with 8 and solve</u> as follows:
</span>

<span> * 8
= </span>

<span>
The 8 in the numerator will be cancelled out with the 8 in the denominator leaving us with only the <u>7 as a solution</u>
Hope this helps :)</span>
Answer: e. 2h + 3 = 10; h = 3.5h
Explanation:
Jane can run 2 miles per hour. (2h)
He need to run 10 miles in total and has done 3 so far. (+ 3 = 10)
The equation can be written:
2h + 3 = 10
2h = 7
h = 7/2 = 3.5

Let the common ratio be r.
then
a2*r*r=a4
rearrange,
r^2=a4/a2=112.5/50=2.25
r=sqrt(2.25)=1.5 = common ratio
