Answer:
C(x) = 5x + 20 (for members)
C(x) = 3.5x (for non-members)
Step-by-step explanation:
Cost of membership = $20
Price of a game per month = $5
So, the linear equation to compute the total cost for a member can be computed by:
C(x) = 5x + 20
where x is the number of games per month
On the other hand, non-members can get one more game per month for $7 which means they get 2 games for $7. The price for a single game is $7/2 = $3.5 a month.
The linear equation to compute the total cost for a non-member is:
C(x) = 3.5x
where x is the number of games per month.
The following system of equations can be used to decide whether to become a member or not, by substituting the number of games in place of x and finding out the total cost.
C(x) = 5x + 20 (for members)
C(x) = 3.5x (for non-members)

Answer:
Step-by-step explanation:
In this question, it is given that, A rectangle with a short side of 6. An arrow points to a smaller rectangle with a short side of 1.5 .
The shorter side of first rectangle is of measurement 6 units and of second rectangle, is of size 1.5units .
To find the scale factor, we have to do division of the shorter sides of the first and second rectangle, that is
So the scale factor is 0.25 .
Using the confidence interval, it is found that the correct conclusion regarding the hypotheses test is given by:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it is tested if the mean is of 150, that is:

At the alternative hypotheses, it is tested if the mean is different of 150, hence:
.
The confidence interval is (158, 167). Since it does not contain 150, we reject the null hypotheses, hence the correct option is:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.

Rate : 2.7 * 10 ^5 kg/hectare
m = 2.7 * 10^5 kg/hectare * 1.0 hectare = 2.7 * 10^5 kg
50°= 1/2
m ( Carbon ) = 1/2 * 2.7 * 10^5 kg = 1.35 * 10^5 kg
The mass of Carbon is 135,000 kg or 135 tons.
