The rental company to hat Oscar should use is the second company because it's cheaper.
<h3>How to illustrate the information?</h3>
The total amount charged for the first boat will be:
= 100 + 35h
where h = number of hours
= 100 + 35(8)
= 100 + 260
= $360
The amount charged for the second company will be:
= 50 × 8
= 400
Therefore, the rental company to hat Oscar should use is the second company because it's cheaper.

Answer:
226.08 in
Step-by-step explanation:
To find how much water this container can hold, we should find the volume of this container.
Volume of cylinder = πr²h
= 3.14 × 3² × 8 (r= d/2 => 6/2 = 3)
= 226.08 in
Answer:
Step-by-step explanation:
Answer:
skewed to the left
Step-by-step explanation:
you can just look at the graph it is negatively skewed, so it is "leaning towards" the smaller numbers, which are to the left
hope this helped :)
Answer: B) There is not convincing evidence because the interval contains 0.
==============================================================
Explanation:
The 98% confidence interval (-0.36, 0.22) means we are 98% confident that the difference of proportions p1-p2 is somewhere between those two endpoints of -0.36 and 0.22 Values in this interval are possible values of p1-p2.
Note how 0 is in this interval. So it's possible that p1 - p2 = 0. Because of this, we fail to reject the null hypothesis. The null in this case is that p1 - p2 = 0 which can be restated as p1 = p2. The null is the assumption that the two population proportions (p1 and p2) are the same.
The alternative hypothesis is that p1-p2 is not zero. If we got a confidence interval like (0.22, 0.55), this example doesn't have 0 in the interval, then that would mean we reject the null since its unlikely that p1-p2 is equal to zero.
----------------
In short,
- If the confidence interval contains 0, then you fail to reject the null
- If the confidence interval doesn't contain 0, then you reject the null.
In this case, we fail to reject the null and we don't have enough evidence to show that p1 = p2 is false. So for now, we assume it's true.
