Step-by-step explanation:
The null hypothesis states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form .
The alternative hypothesis states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms
The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use as his alternative hypothesis.
Answers and Step-by-step explanations:
(a)
We need to figure out the amount (or total cost) for each size candy given that they sell a certain number of each box. For the small box, we're given the cost is $4.70, while the large box is $7.00.
We buy x of the small box, so the total amount should be 4.70 * x, or just 4.70x. We buy y of the large box, so the total amount should be 7.00 * y, or just 7y.
So on the table, the top value should be 4.70x, and the bottom value should be 7y.
(b)
The total number of boxes sold was 45 boxes. Remember that x boxes were small and y boxes were large. Since the number of small boxes plus the number of large boxes is equal to the total of 45, we can write:
x + y = 45
(c)
The total cost was $269, so we can write this as the sum of the amounts that we found in part (a):
4.70x + 7y = 269

Answer: C+2</h3>
Reason:
The largest sin(x) can get is 1, and the same goes for sin(3x).
Consequently, the largest 2sin(3x) can get is 2.
You can visually verify these claims by graphing each function with a tool like Desmos. Take note of the y coordinate of the highest points. See below.
Therefore, the largest f(x) = 2sin(3x)+C can get is 2+C or C+2
Answer: Howard is 155.1 yards from the top of the water reservoir.
Step-by-step explanation:
A right angle triangle is formed. The distance between Howard and the bottom of the reservoir represents the adjacent side of the right angle triangle.
The distance of Howard from the top of the reservoir, h represents the hypotenuse of the triangle.
To determine h, we would apply
the cosine trigonometric ratio.
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 55 = 89/h
h = 89/Cos 55 = 89/0.574
h = 155.1 yards
