Find the volume of a cone with a diameter of 12 m and a height of 7 m.

c. 84 time pi m squared

Step-by-step explanation:

Formula for volume of a cone: pi times radius squared times height divided by 3

for this you don't need to multiply by pi so it's

12 and radius is 6

6 squared  times 7/3

36 times 7/3

83.99999

rounded to 84 time pi m squared

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
