Answer:
Mean Deviation = 5
Step-by-step explanation:
The numbers are given as;
8, 12, 12, 25, 10, 14, 4, 3, 22, 10
Mean = Sum of numbers / Population = 120 / 10
Mean = 12
mean deviation involves finding the sum of the absolute values of the differences between the individual elements and the mean. Then divding by the population.
Mean Deviation = |(8 - 12) + (12 - 12) + ( 12 - 12) + (25- 12) + (10- 12) + 14- 12) + (4- 12) + (3 - 12) + (22- 12) + (10- 12)
| / 10
Mean Absolute Deviation = 5
Answer:
30
Step-by-step explanation:
25 times 1.2= 30
The formula for of a ball is:
S = 4*r^2*pi
or if we express diameter in it:
S = D^2*pi because D=r/2
S1-S2 = (D1^2 - D2^2)*pi
1 = (100 - D2^2)*3,1415
100-D2^2 = 1/3.1415
D2^2 = 100-1/3.1415
D2 = 9.984cm
which means that Diameter will decrease by rate of:
0.016cm/min
