Answer:
The median is 72
Step-by-step explanation:
The median is the middle of a sorted list of numbers. If there is an odd number of values, the median is the value at the middle. Otherwise, it is the mean between the two middle values.
In this question:
Scores: 86, 67, 62, 82, 64 and 77
Sorted: 62, 64, 67, 77, 82, 86
Middle elements: 67 and 77
Median: (67 + 77)/2 = 72
The median is 72
Answer:
1320 times
Step-by-step explanation:
Time = 1 h × (60 min/1 h) = 60 min
Revolutions = 60 min × (22 rev/1 min) = 1320 rev
The blades revolve 1320 times per hour.
Answer:
D. x-intercept is -5 and the y-intercept is -2
A+b=6.1 ---(1)
a-b=1.6 ---(2)
(1)+(2); 2a=7.7
then a=3.85
so b=a-1.6 = 3.85-1.6 = 2.25
so that the two numbers are 2.25 and 3.85
