a trucker drove 500 miles in h hours. If the trucker averaged 60 mph, which linear equation could be used to find the number of
1 answer:
Step-by-step explanation:
Given that,
Distance covered by a trucker, d = 500 miles
Average speed of the trucker, v = 600 mph
A trucker drove 500 miles in h hours. We need to write the linear equation used to find the number of hours that the trucker drove. Average speed is given by :
t is time in hours
If t is h hours,
On solving, h = 5 hours.
Hence, this is the required solution.

Answer:
a) 0.998856
b) 0.997713
c) 0.999120
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Male death rate
114.4 per 100,000 population
So the survival rate is:
(100000 - 114.4)/(100,000) = 0.998856
Female death rate
44.0 per 100,000 population
So the survival rate is
(100000 - 44)/(100,000) = 0.99956
a) If a male in that bracket are randomly selected, what is the probability that he will survive? ( Express the answer with six decimal places.)
The survival rate for males is of 0.998856. So this is the probability that he will survive.
b) If two males in that ages bracket are randomly selected, what is the probability that they both survive?
Each one has a 0.998856 probability of surviving. So
c) If two females in that age bracket are randomly selected, what is the probability that they both survive?
Each female has a 0.99956 probability of surviving. So
