Answer:
11.4
Step-by-step explanation:
57/5 as a mixed number is 11 2/5.
2/5 of a number is also known as 4/10 or 0.4, so add that to 11 to get 11.4.
Part a: what you have to do is add up all of the vehicles and you get 150. Then it says "approximate probability of a passenger car..." so you would take the number of passenger cars (which is 112) and put that number over 150. 112/150. you would get 0.746666666667 and round that up and you would get 75% (B)
Part b: you do the same thing but change the passenger car number into light truck number. (which is 18) 18/150 0.12 which is 12% (B)
Given:
h(t) = -16t² + 90t + 50
g(t) = 28 + 48.8t
h(1) = -16(1²) + 90(1) + 50 = 124
h(2) = -16(2²) + 90(2) + 50 = -64 + 180 + 50 = 166
h(3) = -16(3²) + 90(3) + 50 = -144 + 270 + 50 = 176
h(4) = -16(4²) + 90(4) + 50 = -256 + 360 + 50 = 154
g(1) = 28 + 48.8(1) = 76.80
g(2) = 28 + 48.8(2) = 125.60
g(3) = 28 + 48.8(3) = 174.40
g(4) = 28 + 48.8(4) = 223.20
Between 3 seconds is the answer... though it is not exactly equal but they are nearer in value compared to other number of seconds.
The answer is suppose to be 36x-48
so the closest answer is 3x-4
