Answer:
9.6
Step-by-step explanation:
FH is just half of GH so you add 4.8 twice and there is your answer
(angle of section / 360) x (pi x diameter)
The height of a cylinder is D. 7 halves inches
<h3>How to calculate the height?</h3>
The volume of a cylinder is calculated as:
V = πr²h
r = radius = 1/3
h = height = ?
v = volume = 1 2/9
We will slot the value info the formula. This will be:
V = = πr²h
1 2/9 = 22/7 × 1/3 × 1/3 × h
1 2/9 = 22/63h
Divide through by 22 / 63
h = 1 2/9 ÷ 22/63
h = 11/9 × 63/22
h = 7/2
The correct option is D.

Answer:
d. Independent-samples t-test
Step-by-step explanation:
The independent samples t-test can be described as a test under which two groups are compared on the mean value of a continuous normally distributed variable.
The independent samples t-test model is based on the assumption that the mean score of the dependent variable is different because the of the impact of the independent variable that differentiates the two groups.
The independent-samples t-test is also known as a parametric test in which the means of two independent groups are compared with the aim of ascertaining if there is statistical evidence that the associated population means are significantly different.
In this question, there are two independent groups which we intend to compare in order to investigate the effect of antidepressants. The first group is the group of people given antidepressant, while the second is another group of people that is given a placebo. This is a perfect example of independent-samples t-test.
Therefore, the correct option is d. Independent-samples t-test. That is, the type of parametric test that should be run in order to investigate the effect of antidepressants by giving one group of people an antidepressant and another group of people a placebo.
