Part A= 36% I got my answer by subtracting the part from the total.
Part B= The total number of sixth graders on academic teams is 124. I got this by adding the 45% and the 36% to get 81% and then add the total number of students in both schools, which was 124. So then 81% of 155 is 124.
Jackie would've washed 15 cars, since multiplying 2 x 5 = 10, so you'd have to multiply 3 by 5 to get the amount of cars Jackie washed if Michael washed 10.
has a horizontal tangent line at , and it's clear from the plot that is increasing to the left and descreasing to the right. This means when , so there is an inflection point there and only statement II is true.
Statement III is not true because critical points only occur where or (possibly) when is undefined. Clearly when .
You multiply 225 pets by the 35% of cats giving you the equation of 225×.35 giving you 78.75. But you approximate the 78 which gives you 80. Thus giving the the 35% of cats of 80 cats.
