Consider that a data set of 10 data points has a mean of 5. If every data point was doubled in the set, how might that affect the mean of the data set?
a) The mean would double to 10.
b) The mean would increase by 2 to 7
c) The mean would increase by 50.
d) The mean would remain to be 5.
Answer:
A) The mean would double to 10.
If every data point in a set is doubled, the mean of the set will also double. In this case, the original mean is 5, so when data points are doubled, the mean would be 10.
Explanation:The subject of this question is how the mean of a data set changes when all data points are doubled. The mean, or average, of a data set is calculated by adding all the data points and dividing by the number of points. When every data point is doubled, each point will become twice its original value. This essentially means adding the same set of data points to the original set, thus doubling the sum. When this new sum is divided by the number of data points (which remains the same), the result also doubles. Therefore, if the mean of the original data set is 5, when every data point is doubled, the mean would also be doubled, which means the new mean is 10 – so the correct answer is (a) The mean would double to 10.

Answer:

Step-by-step explanation:
Study Island
Final answer:
The interquartile range of Angela's bowling scores is determined by calculating the difference between the third quartile (Q3) and the first quartile (Q1). In this case, the IQR is D. 8.
Explanation:
To find the interquartile range (IQR) of Angela's bowling scores, we need to identify the first quartile (Q1, 25th percentile) and the third quartile (Q3, 75th percentile) of her data set. The scores are already in ascending order: 144, 146, 148, 150, 152, 154, 156, 158, 160. With ten scores, Q1 will be the average of the 2.5th and 3.5th data points (which is the score at position 3), and Q3 will be the average of the 7.5th and 8.5th data points (which is the score at position 8).
When we look at the data, the first quartile Q1 is at the score 150 (the average of the third and fourth scores since they are the same), and the third quartile Q3 is at the score 158 (the average of the eighth and ninth scores since they are the same). So, the interquartile range is Q3 - Q1 = 158 - 150 = 8.
The correct answer is D. 8.

Satnam is making a cake. He uses a batter made of 300 g of
dry ingredients. If the liquid has to be two sevenths of the
total weight of the batter, how much liquid should he add?
A basketball player makes 80% of her free throws. The random numbers below represent 20 trials for
a simulation. Let the numbers 0 to 7 represent a made free throw and let 8 to 9 represent a missed
free throw. Use this simulation to estimate the probability that the player makes both free throws.
(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)
(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)
Answer:
0.6
Step-by-step explanation:
The numbers 0 to 7 represent a made free throwThe numbers 8 to 9 represent a missed free throw.Given the simulation data
(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)
(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)
A pair that contains only numbers between 0 and 7 shows the player makes both throws.These pairs are:
(4,0) (2,7) (2,0) (5,4) (0,4) (6,5) (4,4) (1,7) (0,4) (1,7) (3,5) (0,3)
There are a total of 12 cases where the player makes both throws.

The length of the unknown leg is 7 meters.
Answer:
1,2,4
Step-by-step explanation:
edge 2020 hope this helps :>
Final answer:
The true statement about finding the unknown side length of the triangle is that the equation a² + (√13)² = 6² can be used, following the Pythagorean theorem. Other stated equations and proposed lengths are incorrect based on the theorem's application.
Explanation:
The question involves applying the Pythagorean theorem to a right triangle with given side lengths. According to the theorem, in any right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two legs (a and b). Therefore, the equation that can be used to find the unknown side length is a2 + b2 = c2. Given a triangle with one side as √13 meters and the hypotenuse as 6 meters, we can solve for the unknown leg.
Firstly, correct application for the Pythagorean theorem here is a2 + (√13)2 = 62, indicating the first statement is true. By substituting √13 for one leg and 6 for the hypotenuse, squaring the values and rearranging, we find the length of the unknown leg. The correct calculation leads to the discovery that the unknown leg length cannot be 7 meters or √23 meters, as those do not fit the requirements set by the question's parameters.
Therefore, the true statements are:
The equation a2 + (√13)2 = 62 can be used to find the unknown length.
Other suggested equations are incorrect applications of the Pythagorean theorem, and the provided side lengths do not result in the unknown leg measuring √23 or 7 meters.

Four boxes are shown in order from the largest volume to the smallest volume. For each box, all of the dimensions are 3.5cm less than the next larger box. To the nearest cubic centimeter, what is the volume of box D?
Answer:
C
Step-by-step explanation:
It would be -12 to go to the last cube so u subtract 12 from every number then multiply the numbers
The correct answer is option B. The volume of box D is approximately 1,715 cubic centimeters.
To find the volume of box D, we'll start by determining the dimensions of each box in sequence from box A to box D. We'll then calculate the volume of box D.
Step-by-Step Process
1. Determine the dimensions of box A:
Length [tex]\( L_A = 32 \) cm[/tex]
Breadth [tex]\( B_A = 25 \) cm[/tex]
Height [tex]\( H_A = 16 \) cm[/tex]
2. Calculate the volume of box A:
[tex]\[ V_A = L_A \times B_A \times H_A = 32 \times 25 \times 16 \][/tex]
[tex]\[ V_A = 12800 \text{ cubic centimeters} \][/tex]
3. Determine the dimensions of box B:
Each dimension is 3.5 cm less than the corresponding dimension of box A.
Length [tex]\( L_B = L_A - 3.5 = 32 - 3.5 = 28.5 \) cm[/tex]
Breadth [tex]\( B_B = B_A - 3.5 = 25 - 3.5 = 21.5 \) cm[/tex]
Height [tex]\( H_B = H_A - 3.5 = 16 - 3.5 = 12.5 \) cm[/tex]
4. Determine the dimensions of box C:
Each dimension is 3.5 cm less than the corresponding dimension of box B.
Length [tex]\( L_C = L_B - 3.5 = 28.5 - 3.5 = 25 \) cm[/tex]
Breadth [tex]\( B_C = B_B - 3.5 = 21.5 - 3.5 = 18 \) cm[/tex]
Height [tex]\( H_C = H_B - 3.5 = 12.5 - 3.5 = 9 \) cm[/tex]
5. Determine the dimensions of box D:
Each dimension is 3.5 cm less than the corresponding dimension of box C.
Length [tex]\( L_D = L_C - 3.5 = 25 - 3.5 = 21.5 \) cm[/tex]
Breadth [tex]\( B_D = B_C - 3.5 = 18 - 3.5 = 14.5 \) cm[/tex]
Height [tex]\( H_D = H_C - 3.5 = 9 - 3.5 = 5.5 \) cm[/tex]
6. Calculate the volume of box D:
[tex]\[ V_D = L_D \times B_D \times H_D = 21.5 \times 14.5 \times 5.5 \][/tex]
[tex]\[V_D = 1714.625 \text{ cubic centimeters}\][/tex]
[tex]\[V_D \approx 1715 \text{ cubic centimeters}\][/tex].
The complete question is:
Four boxes are shown in order from the largest volume to the smallest volume. For each box, all of the dimensions are 3.5cm less than the next larger box. To the nearest cubic centimeter, what is the volume of box D?
A. 3,657 cubic centimeters
B. 1,715 cubic centimeters
C. 1,044 cubic centimeters
D. 299 cubic centimeters
Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5. Enter your answer into the blank equation box. a0
Answer:
-3/5x + y = - 26/5
Step-by-step explanation:
First, I put everything in slope-intercept form, just because it's more simple for me.
y = 3/5x + b
Since we don't have b, we can use the coordinate they give us to solve for it.
-4 = 3/5 (2) + b
-26/5 = b
y = 3/5x - 26/5
Now, we can move the variables around to fit the form:
Ax + By = C
-3/5x + y = - 26/5
I hope this helped!

Alexandra wants to buy a CD for $400 that earns 4% APR and is compounded
quarterly for 3 years. She will be taxed on 20% of the interest that she earns.
What is the total amount of interest Alexandra will earn, after taxes?
O A. $40.58
O B. $12.99
O c. $16.24
O D. $50.73
SUBMIT
The total amount of interest Alexandra will earn, after taxes is, $51.05.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, To calculate the total amount of interest Alexandra will earn, we first need to calculate the annual interest rate.
Since the APR is 4%,
Hence, we can calculate the quarterly interest rate by dividing 4 by 4 = 1%.
Next, we need to calculate the number of quarters in 3 years which is,
⇒ 3 x 4 = 12 quarters.
Now, Using the formula for compound interest, we can calculate the balance of Alexandra's account at the end of the 3-year period:
Balance = Principal (1 + (rate/n))ⁿˣ
where, P = Principal = $400
r = Annual interest rate = 4%
n = Number of times interest is compounded per year = 4 (quarterly)
x = Number of years = 3
Plugging in the values,
Balance = $400 (1 + (0.04/4))¹²
= $463.81
Next, we need to calculate the total amount of interest Alexandra earned, which is the difference between the balance and the principal:
Total interest earned = $463.81 - $400 = $63.81
Since Alexandra will be taxed on 20% of the interest, we need to calculate the amount of tax she will pay:
Tax = 20% of $63.81
= $12.76
Finally, we can calculate the total amount of interest Alexandra will earn after taxes:
Total interest earned after taxes = $63.81 - $12.76 = $51.05
Therefore, the correct answer is, $51.05.

Suppose you are told that the average height of a stone block is 1.39 m rather than 1.4 m. Would that increase or decrease your estimate of the total number of blocks in the pyramid? Explain.
Answer:
Increase
Step-by-step explanation:
Since the total number of blocks in a pyramid is found by dividing the height of pyramid by the height of each block, then the block height of 1.39 m requires more pieces compared to 1.4 m
Illustration
If the height of pyramid was 139 m, the number if blocks each measuring 1.39 m will be 139/1.39=100+1 blocks while if blocks are 1.4m then number will be 139/1.4=99+1 blocks
Therefore, the height of 1.39m will increase the number of blocks

solve for 3 tanx = sqrt3 tanx
Answer:
Correct Answer is D.
Step-by-step explanation:
Solve for tanx,
3tan2x−√3tanx=0
√3tanx(√3tanx−1)=0
Thus tanx=0,tanx=1√3
For tan x =0, the principal solution is x=0,π
For tanx=1√3, the principal solution would be x=π/6,7π/6
The solutions are x = nπ, where n is any integer.
We are given the trigonometric equation 3 tan(x) = √3 tan(x). To solve for x:
Subtract √3 tan(x) from both sides of the equation to get all terms involving tan(x) on one side: Factor out tan(x): Set each factor to zero and solve for x: tan(x) = 0 when x is an integer multiple of π:x = nπ where n is any integer.
This represents all angles where the tangent is zero.
