1,150×9=10,350
Answer:
-31.77
Step-by-step explanation:
95.31/3 since each ticket is the same amount.
This gives you 31.77, which is the price of 1 ticket.
Her balance would still be negative, so change 31.77 to -31.77
Using confidence interval concepts, it is found that the interval estimate of the true population proportion is of (0.35, 0.51).
<h3>What is a confidence interval?</h3>
It is given by the <u>sample proportion plus/minus the margin of error</u>.
Considering the margin of error is half the range, we have that:
M = (0.48 - 0.32)/0.5 = 0.08.
Then, considering the sample proportion is of 0.43, we have that the bounds of the interval are given as follows:

Answer:
Domain = x ≥ 0
Range = y ≥ 20
Step-by-step explanation:
The equation in slope-intercept form would look like this:
y = 4x + 20
The slope is $4 because that is the money that can be made depending on the week. Because he received a random $20 at the beginning, this is just an additional income.
---------------------------------------------------------------------------
In this scenario, the domain (x-values) represent the number of weeks. The range (y-values) represent the total money made.
So the domain is asking, what is the lowest/highest amount of weeks he can save for? We know the number of weeks cannot be negative because he can't save for negative weeks. However, he could save for zero weeks. He can be saving for theoretically infinite weeks. Therefore, the domain is x ≥ 0.
The range is asking, how much money can he save? Since he starts out with a baseline of $20, this is the lowest amount of money he can have. If he were to save for an infinite amount of weeks, he could make an infinite amount of money. Therefore the range is y ≥ 20.
