6 0

Answer:

7 millimeters

Step-by-step explanation:

Volume is the area of the base times it's length.

140/10 is 14

so the area of the triangle is 14

the formula for area of a triangle is base times height divided by 2

d x 4/ 2 = 14

multiply both sides by 2

d x 4 = 28

divide both sides by 4

d=7

0.0931 is the probability that at least 10 pay in cash.

What is a probability simple definition?

The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

Using binomial distribution with n= 15, and p = 0.40,

P(8<X<12) = P(X=9)+P(X=10) + P(X=11)

= 0.0612+0.0245+0.0074

= 0.0931

Therefore,0.0931 is the probability that at least 10 pay in cash.
