Answer:
9.25 or or 9 1/4
Step-by-step explanation:
Your final answer would be 14a-5c
Since all of the numbers share a common number that divides them, a simplified 4:22:30 ratio would be 2:11:15, as it would not be able to divide them further with the same number and still get whole numbers, or 1: 5.5: 7.5, if you wish to split them further to 1.
The values on the horizontal axis are:
at 0 = 64
at one standard deviation (lower, upper) = (60.5 , 67.5)
at two standard deviation (lower, upper) = (57 , 71)
at three standard deviation (lower, upper) = (53.5 , 74,5)
B. P(x > 71) = 1 - P(x < 71) = 1 - P[z < (71 - 64)/3.5] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275
Therefore the no of plants taller than 71 inches will be approximately 0.02275 * 3000 = 68
