stomers who spend more than $30 on a purchase. Data will be gathered and placed into the two-way table below. Customer Spending by Promotion Run Customers Spending More than $30 Customers Spending $30 or Less $10 off $50 15% off $5 off $25 Buy-1-Get-1 Half Off Which statement best describes how the manager can check if there is an association between the two variables? The manager must check relative frequencies by row because there are more than two different promotions. The manager must check relative frequencies by column because there are more than two different promotions. The manager cannot use relative frequencies to look for an association because there are more than two different promotions. The manager should check both relative frequencies by row and by column to look for an association.

The numbers in the sequence will be 40, 80, and 160.

<h3>How to get the values?</h3>

Let x be the first number in the sequence, so the first three numbers are {x, 0.5x, 0.5²x}.

Then

{x/4 + 10, 0.5x - 10, 2(0.5²x) + 10}

0.5x - 10 = x/4 + 10 + c   = x/2 - 10 = x/4 + 10 + c

2(0.5²x) + 10 = 0.5x - 10 + c = x/2 + 10 = x/2 - 10 + c

Solve the second equation for c :

x/2 + 10 = x/2 - 10 + c

c = 20

Substitute this into the first equation and solve for x :

x/2 - 10 = x/4 + 10 + 20

x/4 = 40

x = 160

Then the terms are {160, 80, 40}
