I think it would be 120 because each “x” term is being multiplied by 4 to get the “y” term so 30 multiplied by 4 is 120

Answer:

120

Step-by-step explanation:

As x goes from 1 to 2, y increases by 4 from 4 to 8

As x goes from 2 to 3, y increases by 4 from 8 to 12

We increase by 4 each time

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term which is 4

d is the common difference or the number we add each time which is 4

n is the term we are looking for which is 30

a30 = 4 +4 (30-1)

a30 = 4+4(29)

       = 4+116

      = 120

Answer:

6.1568 to 1

A Democrat is 6.1568 more likely to respond "yes" than a Republican

Step-by-step explanation:

From the provided data, the following relationships can be modeled:

D=2.96I\\I =2.08R

Combining the information to compare democrats to republicans:

D=2.96*2.08R\\D=6.1568R

The estimated odds of a yes response for a Democrat was 6.1568 times higher than for a Republican. This means that a Democrat is 6.1568 more likely to respond "yes" than a Republican.

Answer:

  Domain of set B: {2, 4, -4, 0}

Step-by-step explanation:

The domain of the function whose ordered pairs are listed in set B is the set of first numbers of those pairs: {2, 4, -4, 0}.

_____

<em>Comment on the question</em>

A "set" does not have a domain. A "function" has a domain. To make any sense of this question, we have to interpret the question to mean the function described by the ordered pairs in the set.

Laura sold t-shirts at a festival. She made $4 for each t-shirt she sold. Her expenses were $25. If she made a profit of $71, ho
Mamont248 [21]

Answer:

24 t shirts

Step-by-step explanation:

revenue - expenses = profit

profit = $71

expenses = $25

revenue = money made from t shirts = $4 for each t shirt, x times (she makes $4 for each t shirt and sells x t shirts) = $4 * x

4 * x - 25 = 71

add 25 to both sides to isolate the variable and its coefficient

4x = 96

divide both sides by 6 to isolate x

x = 24
