Step-by-step explanation:

Is she correct? Why or why not?

Answers

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.

find and interpret the mean absolute deviation of the data
55, 46, 39, 62, 55, 51, 48, 60, 39, 45

Answers

Answer:

Mean Absolute Deviation is 6.6.

Step-by-step explanation:

Step 1: Find the mean of this set. First, add up all the data values then you divide them by the amount of date values. In this case, you add all the data values to get 500 and since there are 10 data values do 500/10 to get 50.

Step 2: You have to find the difference of each data value and the mean. Then find the absolute value of the result. For example, 46-50=-4 and the absolute value of this is 4.
Step 3: Add up all the absolute values of the differences. In this case, you add all them up to get 66.
Step 4: Just divide the total by the amount of data values. This would just be 66/10. You get 6.6 and that's your answer. Hope this helped! :)

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)

Answers

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.
