A.) It will take you 1,000,000 / 19 = 52,631.58 minutes = 52,631.58 / 60 = 877.19 hours = 877.19 / 24 = 37 days to spend $1 million.
b.) A penny is 1.55 mm thick, thus 1 million penny will be 1 million x 1.55 = 1,550,000 mm high.
c.) A quarter is 1.75 mm thick, thus 1 million quarter will be 1,000,000 x 1.75 = 1,750,000 mm high.
d.) 1000 mm = 1 m
Therefore, $1 million worth pennies will be 1,550,000 / 1,000 = 1,550 m high.
e.) $1 million worth quarters will be 1,750,000 / 1,000 = 1,750 m high.
Answer:
b = (20*3+11+13)/10
Step-by-step explanation:
First add the number of people on the trip
There are 3 classes
20*3 is the numbers of students since there are 20 students per class
11 teachers and 13 parents
20*3+11+13
Then divide by the number of people per boat
(20*3+11+13)/10
The number of boats needed is
b = (20*3+11+13)/10
By addition theorem of probability,
P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8
Therefore, the probability that randomly selected person likes pizza or burger is 0.8
