I NEED HELP PLEASE! The approach ramp used by a daredevil motorcyclist for flying over a pit of venomous snakes has a rise of 52 feet for every 80 feet in horizontal distance. Find the grade of the ramp. Round to the nearest whole percent.

65%

Step-by-step explanation:

The formula for the grade of the ramp = Rise of the ramp/ horizontal distance of the ramp

Rise of the ramp = 52 feet

Horizontal distance = 80 feet

Grade of the ramp = 52 feet/80 feet

= 0.65

The grade of the ramp is 0.65

Rounding up to the nearest whole percent

Grade of the ramp = 0.65 × 100

= 65%

Therefore, the grade of the ramp to the nearest whole percent = 65%

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
