There are 81 girls to every 72 boys in total, which can be represented by 81/72, which put into decimal form, is 1.125. If you then take the number of boys in the group, 16, and multiply it by this number (because the problem states that the ratio is constant) you can find the number of girls in the group.
16*1.125=18
So there are 18 girls in a group with 16 boys.
Answer:
y=1/3x + 2
Step-by-step explanation:
the y intercept is 2 since that's where the line crosses and the x intercept is at 4
Step-by-step explanation:
a < (a + b)/2 < b
Solve the first inequality.
a < (a + b)/2
2a < a + b
a < b
Solve the second inequality.
(a + b)/2 < b
a + b < 2b
a < b
Both inequalities are true. Therefore, a < (a + b)/2 < b.
Sample space of two fair 6 sided dice is 36.
Product = perfect square are (1, 1), (1, 4), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)
Probability that their product is perfect square = 7/36
