Answer:
The correct option is A.
40 + 1.2m > 48
Step-by-step explanation:
Given that Derek is 40 inches in height, and a rollercoaster rider is required to be at least 48 inches. Since he is growing at an 1.2m per month, we want to find how many months, m it will take for him to reach that 48 inches height.
This, we need the height 1.2m to be added to 40 inches to give at least 48 inches.
1.2m + 40 ≥ 48
or
40 + 1.2m ≥ 48
This is the required equation.
Of all the options, option A is the best.
40 + 1.2m > 48

Answer:
56
Step-by-step explanation:
Let N be the total number of spins.
Probability of A on Red and B on Red = 0.5 x 0 .6 = 0.3 (top branch of tree)
Therefore with N spins, the estimated number of times spinner A and spinner B land on red is 0.3N and we are given this as 84
So 0.3N = 84
N = 84/0/3 = 280
The probability of spinner A on blue and spinner B on blue is 0.5 x 0.4 = 0.2 (lowest branch of tree)
For 280 spins, the estimated number of times that both spinners land on blue is given by 0.2 x 280 = 56
