Answer:
The ball goes 14 meters high
Step-by-step explanation:
Given the function
y= -0.1x^2 + 2x + 4
In the figure attached, the function is shown.
The maximum height is equivalent to the vertex of the function, which is obtained as follows:
Xv = -b/(2a) = -2/(2*-0.1) = 10
Yv = -0.1Xv^2 + 2Xv + 4
Yv = -0.1(10)^2 + 2(10) + 4 = 14
Answer:
Step-by-step explanation:
Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour

Answer: e. test for a difference in two population means
Step-by-step explanation:
Since the researcher takes a random sample of patients and measures their cholesterol levels before and after a treatment cycle of the drug, then the two samples are matched pairs. The difference between both samples would be determined and the mean and standard deviation of this difference is calculated. This would be used to determine the test statistic.
Therefore, the type of hypothesis test that they should use is
e. test for a difference in two population means
