Answer:
the probability that the x-coordinate of the point is negative and the y-coordinate of the point is positive is 16.36%
Step-by-step explanation:
Assuming that each point has the same probability to be chosen ( uniform probability distribution in the rectangle area ) then the probability of choosing a negative x-coordinate and positive y-coordinate is the ratio of the area with those requirements over the total area of the rectangle.
therefore
Ar= area of negative x-values and positive y-values = (-3)*6 = 18
AT= total area of the rectangle = [8-(-3) ]*[6-(-4)] = 110
then
probability = Ar/AT = 18/110 = 0.1636 = 16.36%
Answer:
2) 70,000
Step-by-step explanation:
since they have said estimate meaning frist round off
679 rounds up to 700 and 98 rounds up to 100
700×100
70000
Answer:
The cluster from 4 p.m.–10 p.m. means that most of the texts were sent in the afternoon and evening.
More texts were sent from 6 p.m.–8 p.m. than from 8 p.m.–10 p.m.
Step-by-step explanation:
From 6 a m to 8 a m there were 15 texts,
8 to10 a m: 5, 10 a m to 12 p m: 0,
12 p m to 2 p m: 0,
2 p m to 4 p m: 0,
4 to 6 p m: 29,
6 to 8 p m: 19,
8 to 9 p m, 14,
10 p m to 12 a m: 5.
