Answer:
Step-by-step explanation:
What this question is asking of you is what is the greatest common divisor of 12 and 15. Or, what is the biggest number that divides both 12 and 15.
in order to find this we have to split each number into it's prime components.
for 12 they are 2,2 and 3 (
2
⋅
2
⋅
3
=
12
)
and for 15 they are 3 and 5 (
3
⋅
5
=
15
)
Out of those two groups (2,2,3) and (3,5) the only thing in common is 3, so 3 is the greatest common divisor. That tells us that the greatest number of groups that can exist and have the same number of girls and the same number of boys for each group is 3.
Now to find out how many girls and boys there are going to be in each group we divide the totals by 3, so:
12
3
=
4
girls per group, and
15
3
=
5
boys per group.
(just as a thought exercise, if there were 16 boys, the divisors would have been (2,2,3) and (2,2,2,2), leaving us with 4 groups [
2
⋅
2
] of 3 girls [12/4] and 4 boys [16/4] )
Answer:
get y by itself and simplify
y=3/2x +7
Hi there! Hopefully this helps!

Question A answer: 2.
To find the <u>median</u>, you simply need to order the set from lowest to highest and finding the <u><em>exact middle</em></u>. So it should look like this:
0, 1, <em><u>2</u></em>, 3, 4. So 2 is the median, therefore 2 is the answer to Question A.
------------------------------------------------------------------------------------------------
Question B answer: 2
To find the <u>mean</u>, you have to add all of the numbers together and then you have to <u>divide by the number of items in the set</u>. There are 5 numbers in the set so it should look like this:
0 + 1 + 2 + 3 + 4 = 10.
Since there 5 numbers in the set, we need to divide by 5.
10 / 5 = 2.
Therefore, 2 is also the answer to Question B.

<em>Edit:</em> <em>Whoops, sorry for the explanation...</em>
Slope = (-5+7)/(6 - 7) = -2
y = mx + b
b = y - mx
b = -7 - (-2)(7)
b = -7 + 14
b = 7
equation
y = -2x + 7
answer
<span>a. y = -2x + 7</span>
