Answer:
Let the coordinates of two points P & Q be (x1,y1) & (x2,y2) respectively. Therefore the distance between the two points ...
Step-by-step explanation:
you have to study
1 minute = 60 seconds
15 seconds /60 = 0.25 minutes.
Total time in minutes is 4.25
Divide total copies by total minutes:
153 / 4.25 = 36 copies per minute
1)X=4
2)X=3
3)X=20
1)X=7.25
2)X=1.5
3)X=41
Answer:
The new mean is 76.2
Step-by-step explanation:
Given
Given
Old mean = 71.3
Every observation is increased by 4.9.
Let the data set has N entries, then
The new mean would be
(71.3 *N + 4.9*N)/N
The new mean = 71.3 + 4.9 = 76.2
Solve by finding what 3^-1 equals:
3^-1 = 1/3
Now compare the two fractions:
1/3 > 1/4
