That is not true. To find the midpoint of a line, you must add the values of x’s together and divide by 2 and then add the values of y together and divide by 2. The formula is (x1+x2/2 , y1+y2/2)
It's asking for a composition function where you insert the function g(x) into f(x).
f(g(x))=10(x+8)+25
f(g(x))=10x+80+25
f(g(x))=10x+105
We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.
The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36
The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55
55 * 36 = 1980 different groups in the committee
35829262 in standard form is 0.35829262 x 10 ^ 8
