Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Art 68.7 50 15.4
Science 54.2 55 7.9
She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference? (10 points)
Group of answer choices
Yes, because the mean is larger in the art book
No, because the mean is larger in the art book
Yes, because there is a lot of variability in the art book data
No, because there is a lot of variability in the art book data
Answer:
No, because the mean is larger in the art book

7x−5y=28?
Select each correct answer.
A. (4, 10)
B. (−1, −7)
C. (7, 9)
D. (−6, −14)
When I tried to solve for 5y I got 5.6
Options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
7x - 5y = 28
From the above equation:
y = mx + c
On comparing:
y = (7/5)x - 28/5
m = 7/5
c = -28/5
After plotting the graph of the equation:
From the graph:
B. (−1, −7)
D. (−6, −14) are the ordered pairs in the form (x, y) that are solutions to the equation.
Thus, options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.

Julie paid $43 for 8 shirts. At this rate, how much will she pay for 12 shirts?
Answer:
$64.56
Step-by-step explanation:
If she paid 43 dollars for 8 shirts, then that means she paid about 5.38 dollars each for one shirt. (43/8 = 5.375)
Because we are finding the price for 12 shirts, multiply the price of one shirt ($5.38) by the total number of shirts (12) we are buying so, 5.38*12 = $64.56
Our answer is $64.56. :D
Answer:
$64.50
Step-by-step explanation:
To find the unit rate: 43/8=5.375
To find how much for 12 shirts: 12 x 5.375 = 64.50.

5x - 29.4 + 1/2x when x is 11/5
Answer:
-17.3
Step-by-step explanation:
Evaluate 5 x + x/2 - 29.4 where x = 11/5:
5 x + x/2 - 29.4 = 5×11/5 - 29.4 + 1/2×11/5
Hint: | Express 5×11/5 as a single fraction.
5×11/5 = (5×11)/5:
(5×11)/5 - 29.4 + (11/5)/2
Hint: | Express (11/5)/2 as a single fraction.
(11/5)/2 = 11/(2×5):
(5×11)/5 - 29.4 + 11/(2×5)
Hint: | Cancel common terms in the numerator and denominator of (5×11)/5.
(5×11)/5 = 5/5×11 = 11:
11 - 29.4 + 11/(2×5)
Hint: | Multiply 2 and 5 together.
2×5 = 10:
11 - 29.4 + 11/10
Hint: | Approximate 11/10.
11/10≈1.1:
11 - 29.4 + 1.1
Hint: | Evaluate 11 + 1.1 using long addition.
| 1 | 1. | 0
+ | | 1. | 1
| 1 | 2. | 1:
12.1 - 29.4
Hint: | Factor out a negative sign in 12.1 - 29.4 in order to subtract.
12.1 - 29.4 = -(29.4 - 12.1):
-(29.4 - 12.1)
Hint: | Subtract 12.1` from 29.4`.

Which phrases can be represented by the expression 60w? Check all that apply. the product of sixty and a number sixty times a number the difference of a number and sixty the quotient of a number and sixty a number divided by sixty the sum of a number and sixty
Answer:
The product of 60 and a number and Sixty times a number.
Step-by-step explanation:
This is because everything else like the difference, the sum, the quotient, and divided are not multiplication cause in this case 60w is equal to 60*w; and the product the same as multiplication. Also, time is the same as multiplying.
The expression 60w can be written in words will be the product of sixty with a number 'w' and sixty times a number 'w'. Then the correct options are A and B.
How to convert the equation into a sentence?The act of converting mathematical equations into a specified statement is known as equation-to-sentence transformation.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expression is given below.
⇒ 60 w
The expression is also written as,
⇒ 60 w
⇒ 60 × w
The expression 60w can be written in words and will be the product of sixty with a number 'w' and sixty times a number 'w'. Then the correct options are A and B.

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be the same. The correct option is B.
What is the associative property of addition?Suppose you've got 3 numbers a, b, and c.
Then, we have
(a+b) + c = a + (b + c)
This property is called associative property and it is called so because we can associate b with a, or b with c without altering the value of the addition.
What is the commutative property of addition?The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be the same.
For two numbers x and y, we have:
x + y = y + x
Thus, if we take 3 numbers as a,b and c, then:
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
And so on for any amount of numbers.
The best use of the associative and commutative properties to make simplifying -1/3-10+7+2/3+5 easier is [-1/3+(-10)]+[7+2/3+5].
Hence, the correct option is B.
