Answer:
Step-by-step explanation:
Let x represent the number of rides.
We have been given that a carnival has two payment options.
In Plan A, you pay $10 admission plus $3 for each ride. The total cost for x rides using plan A would be .
In Plan B, you pay a $20 admission plus $1 for each ride.The total cost for x rides using plan B would be .
Now we will show that plan B is best buy by showing that cost of x rides in plan B is less than plan A as:
Therefore, our required inequality would be .

You did not attach any picture to solve this problem. We cannot calculate for the value of A’ and D’ without the correct graph. However, I think I found the correct graph (see attached), please attach it next time.
So we are given that the figure is dilated by a factor of, meaning that all of its end points are multiplied by 2. By this rule, all we have to do is to simply multiply the initial coordinates of A and D by 2 to get A’ and D’, that is:
A’ = (-1 * 2, -1 * 2) = (-2, -2)
<span>D’ = (2 * 2, -1 * 2) = (4, -2)</span>
Answer:
z-score for value 560 = 0.6
z-score for value 650 = 1.5
z-score for value 500 = 0
z-score for value 450 = -0.5
z-score for value 300 = -2
Step-by-step explanation:
We are given a sample with a mean of 500 and a standard deviation of 100.
i.e., = 500 and
= 100
The z score distribution is given by;
Z = ~ N(0,1)
where X represents the data values;
- So, z score for value 560 is;
z score = = 0.6
- So, z score for value 650 is;
z score = = 1.5
- So, z score for value 500 is;
z score = = 0
- So, z score for value 450 is;
z score = = -0.5
- So, z score for value 300 is;
z score = = -2
