Question 8 of 25
If a sample mean is 96, which of the following is most likely the range of
possible values that best describes an estimate for the population mean?
O A. (76, 108)
O B. (82, 114)
O C. (78, 110)
O D. (80, 112)
The correct range is (80, 112).
The correct option is (D).
What is mean?Mean is also said to be arithmetic mean. The meaning of mean is to evaluate the average. It is defined as the average of the given numbers.
As per the given data:
We are given the mean of the sample.
The mean of the sample = 96
In each option, a range is given.
We have to find out which is the correct range for the given mean.
For a range (a, b) the mean is given by:
mean = (a + b)/2
By using the above definition and checking all the options:
For (76, 108)
mean = (76 + 108)/2 = 92, Not the correct range
For (82, 114)
mean = (82 + 114)/2 = 98, Not the correct range
For (78, 110)
mean = (78 + 110)/2 = 94, Not the correct range
For (80, 112)
mean = (80 + 112)/2 = 96, The correct range
The correct range is (80, 112).
Hence, the correct range is (80, 112).

Step-by-step explanation:
solve h(x) = 5 - 9x Find h(8)
h(x) = 5 - 9x
h(8) = 5 - 9×8 ( putting value x = 8)
h(8) = 5 - 72
h(8) = -67
Answer is -67.
Answer:
h(8) = -67
Step-by-step explanation:
To solve this problem, we take x in h(x) and input it for x within the problem.
In this case, h(8), so 8 is replacing x in 5-9x.
h(8) = 5 - 9(8)
h(8) = 5 - 72
h(8) = -67

Let's simplify step-by-step.
5x^3 + 3 + 2x^3 − x^2 + 1
= 5x^3 + 3 + 2x^3 + −x^2 + 1
Combine Like Terms:
= 5x^3 + 3 + 2x^3 + −x^2 + 1
= ( 5x^3 + 2x^3 ) + ( −x^2 ) + ( 3 + 1 )
= 7x^3 + −x^2 + 4
Answer:
= 7x^3 − x^2 + 4

Seth’s bank charges $5 a month to maintain a checking account and $0.50 for each check Seth writes. Last month, Seth paid a total of $6.50 in checking account fees. How many checks did he write?
A 1 C 3
B 2 D 4
Answer:
13
Step-by-step explanation:
Since Seth pays $0.50 for each check he writes, he would write (let x be how many checks Seth wrote) "x" checks for $6.50. That means;
1 = 0.50
x = 6.50
Now let us set up a fraction:
[tex]\frac{0.5}{1}=\frac{6.5}{x}[/tex]
Step 1: Cross multiply
[tex]0.5x=1\cdot \:6.5[/tex]
[tex]0.5x=6.5[/tex]
Step 2: Divide both sides by [tex]0.5[/tex]
[tex]\frac{0.5x}{0.5}=\frac{6.5}{0.5}[/tex]
Simplify
[tex]x=13[/tex]
Therefore, Seth will write 13 checks for $6.50

Answer:
The area of the triangle is 31.5 ft^2
Step-by-step explanation:
Mathematically, the area of the triangle is the product of the base and the height divided by 2
From the given diagram, the base is of the measure 4 ft + 5 ft = 9 ft
The measure of the height is 7 ft
Thus, we have the area of the triangle as;
1/2 * 7 * 9 = 31.5 ft^2

How much glass is needed to construct a hexagonal (6-sided) fish tank? The tank is
4 feet tall and each pane is 11 feet wide. The tank's bottom is not made of glass.
Answer:
Each side of the hexagon is a rectangle of height 4ft and width 11ft.
The area of each one of these rectangles is:
A = 4ft*11ft = 44ft^2
And a hexagon has 6 faces, so the fish tank will have 6 of these rectangles, then the total area is:
area = 6*44ft^2 = 264 ft^2
We know that the base of the hexagon is not made of glass, but we do not know if the top is made of glass or not.
In the case that the top is not made of glass, the amount of glass needed is 264 ft^2
If the top is made of glass, then we need to add the area of a hexagon of side 11 ft, which is:
a = (3*√3)*(11ft)^2/2 = 314.4ft^2
Then the total area in this case is:
264 ft^2 + 314.4ft^2 = 578.4 ft^2
This is the total amount of glass needed to construct the tank if the top of the tank is made of glass.
