Answer:
7 : 8
Step-by-step explanation:
150 adults complete a survey. 80 are women. Thus the ratio of number of men to number of women . Therefore the number of men to number of women be 7 : 8
Mario's mistake is made when doing reciprocal.
7 / (2/3) =
I cannot divide by 2/3, but if I do reciprocal, I can multiply by 3/2. The seven comes first, so it should not be flipped.
Mario's mistake was when he flipped the 7 (or 7/1) to 1/7.
H(x) = 6x + 1
turn h(x) into y
y = 6x + 1
switch the x and the y
x = 6y + 1
solve for y
6y = x - 1
y = 1/6x - 1/6
y = 1/6(x - 1)
now stick the inverse notation in for y....h -1(x)
h-1(x) = 1/6(x - 1).....I think I did that right
