A tennis ball has a diameter of 2.7 in. How many tennis balls will fit inside of a storage unit that is 4 feet wide, 2.5 feet long, and 2 feet high?

Step-by-step explanation:

Given that,

The diameter of a tennis ball, d = 2.7 inches

We need to find the number of tennis balls will fit inside of a storage  unit that is 4 feet wide, 2.5 feet long, and 2 feet high.

Let there are x number of tennis balls.

Approximately

x = 7

Hence, there are 7 balls.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
