Answer:
Step-by-step explanation:
Total = 48
Games = 6
Average = Total / number of games
Average = 48 / 6
Average = 8
They lost an average of 8 points per game.
The OKC Thunder have lost their last 6 games by a total of 48 points. What is the average amount of points OKC has lost per game?
Answer:-Given,Points = 48
Number of games they lost = 6
Now,→ Average amount of points OKC has lost per game = Total points / number of games
→ Average = 48/6
→ Average = 8
OKC has lost 8 points per game.

Caroline started the day with 75 tickets at the fair. At the end of the day, the number of tickets she had was 32% less than what she started with. How many did she have at the end of the day
Answer: 24
Step-by-step explanation:
75(0.32) = 24
I got this because 75 is what it started as so I put it as the start of the equation. Then I saw the 32% which would be equal to 0.32 so multiplying would get me the answer because it is a decimal which is smaller than one.

The 98 percent confidence interval (−0.248,−0.134) was constructed to estimate the slope of a regression model for a bivariate data set with 20 values. Alice claims that a sample size of 25 will produce a narrower interval, all other things remaining the same. Desmond claims that a sample size of 15 will produce a narrower interval. Which statement is true about the claims made by Alice and Desmond?
a. Alice’s claim is correct.
b. Desmond’s claim is correct.
c. Both Alice’s claim and Desmond’s claim are correct.
d. Neither Alice’s claim nor Desmond’s claim is correct.
e. There is not enough information to determine whether the claims are correct.
Answer:
a. Alice’s claim is correct.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval is inversely proportional to the sample size. This means that a smaller sample size leads to a smaller margin of error and a narrower interval, while a larger sample size leads to a larger margin of error and a wider interval.
Alice claims that a sample size of 25 will produce a narrower interval
25 > 20, so smaller margin of error and narrower interval, which means that Alice is correct.
Desmond claims that a sample size of 15 will produce a narrower interval.
15 < 20, so larger margin of error and wider interval, which means that Desmond is wrong.
So the correct answer is given by option a.
About 7% of the population has a particular genetic mutation. 400 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups of 400.
Answer:
5.10 people
Step-by-step explanation:
Calculation to Find the standard deviation for the number of people with the genetic mutation
Using this formula
Standard deviation = √ ( n * p * q)
Where,
n = 400
p = .07
q = 100%-7% = 93% or .93
Let plug in the formula
Standard deviation =√400*07*.93
Standard deviation =√26.04
Standard deviation = 5.10 people
Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.
Geometry help!!! Find the measure of angle A!
Answer:
19.3
Step-by-step explanation:
Since the sum of all angles inside of a triangle add up to 180, all three angles add up to 180.
x + 5x + 4x - 13 = 180
Now, we work backwards to figure out what x is.
10x - 13 = 180
Add 13 on both sides
10x = 193
Divide by ten to isolate x
x = 19.3
Since angle A is x, then it is 19.3

195
Since the value of y varies directly with x, the value of x when y equals 9 is 9/13
Given the following data:
x = 195
y = 15
To find the value of x when y = 9:
This is a direction proportion exercise and you're required to solve for the value of x when the value of y is equal to 9.
First of all, we would determine the constant of proportionality (k) for the mathematical expression.
y = kx
15 = 195k
k = 13
Now, we can find x:
y = kx
9 = 13 x
x = 9/13
Therefore, the value of x when y equals 9 is 9/13

The simplified Expression of (27\(r)^{1/3\) is 3\(r^{1/3\).
What are Exponent and Power?Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as \(3^4\), where 4 is the exponent and 3 is the base. The whole expression 34 is said to be power.
Given:
We have to simplify (27\(r)^{1/3\)
Now, prime factorizing 27 = 3 x 3 x 3
(27\(r)^{1/3\)
= (3 x 3 x 3 x \(r)^{1/3\)
= (3³ \(r)^{1/3\)
= \(r^{1/3\) \((3^3)^{1/3\)
= 3\(r^{1/3\)

The margin of error in a confidence interval estimate accounts for:_________
Answer:
The percentage points within which the obtained results would differ from the real population value.
Step-by-step explanation:
The ideas of the margin of error and confidence interval are borne from the observed truth, which is that there is always room for error in any statistically computed figure such as a survey or poll. For example, the result of a poll could show an 80% confidnce interval with a margin of error of 3%. This simply means that if the poll was repeated, 80% of the real population would fall within an estimate of 3%.
Statistics are not always error proof. Sometimes, the results might even be totally different from the computed results. So, it is very important that room is made for the possibility of an error, and that is why we need the mrgin of error.

The graph of g is a translation 1 unit down of the graph of f(x) = 3|x| – 4. The rate of change of g over the interval 2 ≤ x ≤ 5 is
The solution is: the rate of change is 3.
Here, we have,
Since the graph of f(x) is translated 1 unit down, we need to decrease the value of f(x) by 1 to find g(x):
g(x) = f(x) - 1
f(x) = 3|x| – 4
so, we get,
g(x) = 3|x| – 4 - 1
= 3|x| – 5
Now, to calculate the rate of change over the interval 2 <= x <= 5, we can use the formula below:
rate = g(5) - g(2)/ 5-2
so, we get,
rate = 9/3 = 3
Therefore the rate of change is 3.

Find the approximate radius of a circle with a circumference of 34.48 inches. Use 3.14 for pie. Round to the nearest 100
Answer:
r = 5.49
Step-by-step explanation:
The formula for the radius of a circle is circumference/2(3.14).
34.48/2(3.14) = 5.49
The radius of the circle is equal to 5.49 inches.
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
Given here: Circumference as 34.48 inches and π=3.14
Now circumference of the circle is given by
2πr=34.48
r=34.48/2×3.14
r=5.49 inches

Find the missing angle
PLZ HELP :/
Answer:
The missing angle are: 123°, 65°
5x+10° = 65°
11x +2° = 123°
Step-by-step explanation:
11x+2° = 5x+10°+58° {the exterior angle formed by producing the side of triangle is equal to two non adjacent angle}
or, 11x - 5x = 58°+10°-2°
or, 6x = 66°
or, x = 66°/6
or, x = 11°
therefore, x = 11°
11x+2° = 11×11°+2°
= 121°+2°
= 123°
5x+10° = 5×11°+10°
= 55°+10°

A shoe store developed the following estimated regression equation relating sales to inventory investment and advertising expenditures. where
^y = 25 + 10x1 + 8x2
x1 = inventory investment ($1000s)
x2 = advertising expenditures ($1000s)
y = sales ($1000s)
a. Predict the sales resulting from a $15,000 investment in inventory and an advertising budget of $10,000.
b. Interpret b1 and b2 in this estimated regression equation.
Answer: See explanation
Step-by-step explanation:
a. Predict the sales resulting from a $15,000 investment in inventory and an advertising budget of $10,000.
To solve this, in the regression equation, we have to replace x1 with 15 and then replace x2 with 10. This will be:
y = 25 + 10x1 + 8x2.
y = 25 + 10(15) + 8(10)
y = 25 + 150 + 80
y = 255
Therefore, the predicted sales is 255.
b. Interpret b1 and b2 in this estimated regression equation.
A change in b1 which is the inventory investment will bring about a change of 10 units in the sales as long as other values are constant.
A change in b2 which is the Advertising expenditure will bring about a change of 8 units in the sales as long as other values are constant.
the volume of a cylinder is 8,478 cubic inches, and the radius is 15 inches. Which measurement is closest to the height of this cylinder in inches?
Answer:
The height of the cylinder 'h' = 12 inches
Step-by-step explanation:
Explanation:-
Given Volume of the cylinder = 8,478 cubic inches
Radius of the cylinder = 15 inches
Volume of the cylinder is determined by
\(V = \pi r^{2} h\)
8,478 = 3.14 × (15)² h
\(h = \frac{8478}{3.14 X 225} = 12 inches\)
The height of the cylinder 'h' = 12 inches
