40 represents a total, but then 45% represents a part. First of all, let's find the amount of girls in the club.
45% of 40
= 18 girls
If it was increased to 56%:
56% of 40
= estimated 23, since we can't have two fifths of a person.
23 - 18 = 5 new girls joined.
P=(3×2)+(2.5×2)3.5
p=6+5(3.5)
p=11(3.5)
p=38.5 feet
Add total perimeter in the scaled metric.
Multiply by the scale factor.
Done.
Micas conclusion is incorrect. There were 30 high school students surveyed and 15 of them said that they could drive, and out of the 60 college students half of them also said they could drive. In both situations, half of the groups were able to drive which shows that his conclusion of knowing that a person is in college means they are more likely to drive is incorrect.
