Answer:
60.
Step-by-step explanation:
This is a permutation exercise because order matters. The formula is n!/(n-r)!. In this case n=5 and r=3 so,
5!/(5-3)! = 5!/2! = 5!/2 = (5*4*3*2*1)/2 we can simplify the 2 and obtain 5*4*3= 60.

the number of athletes who do not play basketball is 26.
Step-by-step explanation:
<u>DATA:</u>
Athletes surveyed = 107 athletes
<u>Athletes who play basketball</u>
Athletes who play baseball = 48 athletes
Athletes who don't play baseball = 33 athletes
Athletes who play basketball = athletes who play baseball + athletes who don't play baseball
Athletes who play basketball = 48 + 33
Athletes who play basketball = 81
<u>EQUATION:</u>
Total athletes = Athletes who play basketball + Athletes who don't play basketball
107 = 81 + x
x = 107 - 81
x = 26
Therefore, the number of athletes who do not play basketball is 26.

Answer:
0.25feet
Step-by-step explanation:
The equation is not well written. Let the equation of the height be modelled as;
h = -16d²+8d+4
The velocity of the ball is zero at its maximum height.
Velocity = change in displacement/time
v = dh/dd
Differentiate
v = -32d+8
Since dh/dd = v = 0
0 = -32d+8
Add 32d to both sides
0+32d = 8
32d = 8
Divide both sides by 32
32d/32 = 8/32
d = 1/4
d = 0.25feet
Hence the maximum height of the tennis ball is 0.25feet
Note that the modeled equation was assumed. You can apply the same calculation to any equation given
