Answer: 4
Step-by-step explanation:
The number 10 is not divisible by 4 neither can you multiply a number from the factors of 20 by 4 to give you 10.
Volume of sphere = 4/3(pi)(r^3)
Given pi = 3.14, r = 10
4/3(3.14)(10^3)
= 4186.66
Now round to hundredths
Solution: 4186.67 cubic meters
We want to make a 4 players team, and there are total 8 players. As we know the order of selection does not matter in a team of players, only the combination of players matters.
So we would use concept of Combinations and It will be choose 4 out of 8 players.
The formula for Combination is given as follows :-

Hence, Total number of different teams = 70 combinations.
Answer:
65.426
Step-by-step explanation:
Given that:
Mean height (m) = 68 inches
Standard deviation (s) = 2 inches
Height required to be taller than 90% of the class :
P(Z > x) = 0.9
The corresponding Zscore is - 1.282 (Z probability calculator)
Using the Zscore relation :
Zscore = (x - m) / s
-1.282 = (x - 68) / 2
-1.282 * 2 = x - 68
-2.564 = x - 68
-2.564 + 68 = x
x = 65.436
