Levi has joined the a Frequent Coffee Buyer program with a local cafe. The program costs $5 per month which allows him to get a

discounted coffee price of $3 per cup. Answer the questions below regarding the relationship between the of number of cups of coffee purchased and the total monthly cost.
The independent variable, x, represents the
total monthly cost
, and the dependent variable is the
number of coffee cups purchased
, because the
total monthly cost
depends on the
number of coffee cups purchased
.
A function relating these variables is A(x) =A(x)=
.
So A(12) =A(12)=
, meaning 1212
cups of coffee will cost


dollars monthly
.

7/10 people voted for team A. 3/5 of those people wore red caps. What fraction of those people wore red caps AND voted for team
sergejj [24]

Answer:

<em>21/50</em>

Step-by-step explanation:

Fraction that voted for team A = 7/10

Fraction of those that wear red cap = 3/5 of fraction of team A

Fraction of those that wear red cap = 3/5 of 7/10

Fraction of those that wear red cap = 3/5*7/10

Fraction of those that wear red cap = 21/50

<em>Hence the fraction of people that wear red cap is 21/50</em>

A red die and a blue die are rolled. You win or lose money depending on the sum of the values of the two dice. If the sum is 6 o
olganol [36]

Answer:

The expected value of X is $0.0833.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

For each dice, there are 6 possible outcomes(values from 1 to 6). So for 2 dices, there are 6^2 = 36 desired outcomes.

Desired outcomes:

Sum 5: (1,4), (2,3), (3,2), (4,1).

Sum 6: (1,5),(2,4),(3,3),(4,2),(5,1)

Sum of 9: (3,6), (4,5), (5,4), (6,3)

Sum of 10: (4,6), (5,5), (6,4)

Sum of 12: (6,6)

Probabilities:

5 + 3 = 8 outcomes in which the sum is 6 or 10, that is, 8/36 probability of winning $4.

4 + 4 + 1 = 9 outcomes in which the 5, 9, or 12, that is, 9/36 probability of winning $1.

36 - (8 + 9) = 36 - 17 = 19 remaining outcomes, that is, 19/36 probability of losing $2.

What is the expected value of X?

Multiplication of each outcome by its probability. So

E(X) = \frac{8}{36}*4 + \frac{9}{36}*1 - \frac{19}{36}*2 = \frac{8*4 + 9*1 - 19*2}{36} = \frac{32 + 9 - 38}{36} = \frac{3}{36} = 0.0833

The expected value of X is $0.0833.
