The total of sides on a die is 6. Odds that you get green is 3/6 or 1/2, red is 2/6 or 1/3, blue is 1/6 so the payout is as follows
if the dice is estimated to roll 6 times like this
green, green, green, red, red, blue or $2, $2, $2, $0, $0, $6 and the total of the amount won is $12 in 6 games so 12/6=
$2 to roll each time

Answer:
A. 40.7%
Step-by-step explanation:
The selling price for a $5 profit will be ...
$12.75 +5.00 = $17.75
From $29.95, this represents a change of ...
(17.75 -29.95)/29.95 × 100%
= -12.20/29.95 × 100% ≈ -40.7346%
The bookstore can offer a maximum discount of about 40.7%.
Answer:
Decision Rule: To reject the null hypothesis if t > 1.328
t = 3.913
Step-by-step explanation:
The summary of the given statistics include:
sample size n = 21
the correlation between the number of passengers and total fuel cost r = 0.668
(1) We are tasked to state the decision rule for 0.10 significance level
The degree of freedom df = n - 1
degree of freedom df = 21 - 1
degree of freedom df = 19
The null and the alternative hypothesis can be computed as:
The critical value for is = 1.328
Decision Rule: To reject the null hypothesis if t > 1.328
The test statistics can be computed as follows by using the formula for t-test for Pearson Correlation:
t = 3.913144
t = 3.913 to 3 decimal places
D
because the median of A is 20, the median of B is 30
