The list shows the number of songs that five students each downloaded last week.
32, 43, 38, 28, 51
What is the mean absolute deviation of the numbers in the list?
F 34.4
G 6.88
H 38.4
J 7.68
Answer:
g)6.88
Step-by-step explanation:
We’ll begin by finding the mean of the data set.
32+43+38+28+51=192 then 192/5=38.4
Then find the absolute value of the difference between each data value and the mean.
l32-38.4l=6.4
l43-38.4l=4.6
l38-38.4l=0.4
l28-38.4l=10.4
l51-38.4l=12.6
Lastly, find the sum of the absolute values and divide by the number of the values
6.4+4.6+0.4+10.4+12.6=34.4
34.4/5=6.88

Mario should have multiplied the x-values by $6.50 to get the y-values
Mario should have multiplied the x-values by 5 to get the y-values.
Answer:
It is C ......
Step-by-step explanation:
The requried, Mario should have multiplied the x-values by $6.50 to get the y-values. Option C is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Mario made the error of multiplying x by 65 to get y. The correct relationship between the quantities in the table is that y is equal to x multiplied by $6.50. Therefore, Mario should have multiplied the x-values by $6.50 to get the y-values.
So, the correct option is:
Mario should have multiplied the x-values by $6.50 to get the y-values.

Which expressions are equivalent to 7(-3/4x-3)? Select two options.
-5 1/4x-21
-7 3/4x-7(3)
6 1/4x-21
6 1/4x-4
7(-3/4x)-7(3)
Answer:
Step-by-step explanation:
7(-3/4x-3) is the same as
7(-3/4x)-7(3) and
-5 1/4x-21
Let me explain this a little bit more.
If you take the 7 times the first part or -3/4x you get 7(-3/4x) You take 7 times the second part you get -7(3)
When you actually solve them:
7(-3/4x) = -5 1/4x and -7(3) = -21.
hope this helps.
7(-3/4x-3) is the same as that of 7(-3/4x)-7(3) and -5¹/₄x- 21.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
If you take the 7 times the first part or -3/4x you get 7(-3/4x) You take 7 times the second part you get -7(3)
When you actually solve them:
7(-3/4x) = -5¹/₄x -7(3)
7(-3/4x) = -21.
Therefore, 7(-3/4x-3) is the same as that of 7(-3/4x)-7(3) and -5¹/₄x- 21.

Figure RST is reflected about the y-axis to obtain figure R’S’T’:
Which statement best describes the relationship between the two figures?
A. Figure RST is bigger than figure R’S’T’.
B. Figure RST is congruent to figure R'S'T'.
C. The measure of angle R is equal to the measure of angle S’.
D. The measure of angle R is equal to the measure of angle T’.
Answer:
B
Step-by-step explanation:
Flipping a graph keeps the figures size the same, so it isn't A. Flipping it doesn't rotate the angles either(R is equal to R', S to S' etc.), so the answer is B.

Is she correct? Why or why not?
Answer:
Incorrect
Step-by-step explanation:
Mandy is incorrect because 2^3 or 2 to the 3 is 2 x 2 x 2 which is 8, but 3^2 or 3 squared is 3 x 3 which is 9.
8 does not equal 9 so she is incorrect.
Answer:
No, she is incorrect.
Step-by-step explanation:
[tex]2^{3}[/tex] equals 8 and [tex]3^{2}[/tex] equals 9. Mandy probably multiplied the 2 and 3 by the exponent instead of by itself a number of times equal to the exponent. 2^3 is equivalent to 2*2*2, not 2*3. 3^2 is 3*3, not 3*2. Therefore she is incorrect because they are not equal.
