The volume of a sphere is:
V=(4pr^3)/3 so the initial volumes is:
Vi=(4p*4.5^3)/3=121.5p in^3 (before match, approx 381.7 in^3)
Vf=(4p*4.4^3)/3=340.736p/3 (after match, approx 356.8 in^3
Vf-Vi=24.9 in^3
So the ball lost about 24.9 in^3 of air during the match...
Answer:
Step-by-step explanation:
The distance between two points is
d^2=(y2-y1)^2+(x2-x1)^2
D) points (0,0) and (9,12)
d^2=(9-0)^2+(12-0)^2
d^2=81+144
d^2=225
d=15
E) points (1,2) and (-3,5)
d^2=(-3-1)^2+(5-2)^2
d^2=16+9
d^2=25
d=5
Answer:
The desviation is 8 4/7 or 8.571
Step-by-step explanation:
The conversion for any variable X to a standard z is
![Z=\frac{X-\[Mu]}\\{\[Sigma]}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BX-%5C%5BMu%5D%7D%5C%5C%7B%5C%5BSigma%5D%7D)
where mu is the mean and sigma de desviation
You can find the value of Z whith the tables of the accumulated probability function. The accumulated probability for the mean is 0.5 .Remenber that the accumlated probability function represent the area at the left of an abscissa. Then
0.5+0.3531=0.8531
Acording to the accumulated probability function table, a Z=1.05 has an area of 0.8531 at its left.
Now it is only solving the equation
![\[Sigma]=\frac{X-\[Mu]}{Z}](https://tex.z-dn.net/?f=%5C%5BSigma%5D%3D%5Cfrac%7BX-%5C%5BMu%5D%7D%7BZ%7D)

σ=8.571
Answer:
7 / 36
Step-by-step explanation:
Using the sample space attached,
Required outcome = multiple of 5 from the sun of two rolled dice = 7
Total possible outcomes =(number of faces)² = 6² = 36
Therefore, the probability of obtaining a sum which is a multiple of 5 is :
P(sum which is a multiple of 5) :
Required outcome / Total possible outcomes
= 7 / 36
