Answer:
265 quarters ($66.25)
Step-by-step explanation:
10$ in quarters is 250 quarters.
you subtract the 15 from winning (=235), then add 50 for the jackpot (=285). Subtract another 20 for her final plays (=265).
Answer:




Step-by-step explanation:
The probability mass function P(X = x) is the probability that X happens x times.
When n trials happen, for each
, the probability mass function is given by:

In which p is the probability that the event happens.
is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:

The sum of all P(X=x) must be 1.
In this problem
We have 3 trials, so 
The probability that a wafer pass a test is 0.7, so 
Determine the probability mass function of the number of wafers from a lot that pass the test.

Answer:
846 m³
Step-by-step explanation:
The solid consists of a rectangular prism and a rectangular pyramid.
V = LWH + (1/3)LWh
V = 9 m * 6 m * 12 m + 1/3 * 9 m * 6 m * 11 m
V = 648 m³ + 198 m³
V = 846 m³
