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

(b+13)/2 = 5b/1.5
solve for b using scale factor.
Guys I'm completely lost... Can you please show your work so I know how to get the answer for future problems like this!!
Answer:
0
Step-by-step explanation:
(b+13)/2=5b/1.5
We move all terms to the left:
(b+13)/2-(5b/1.5)=0
We add all the numbers together, and all the variables
(b+13)/2-(+5b/1.5)=0
We get rid of parentheses
(b+13)/2-5b/1.5=0
What are the like terms in the expression below?
3x + 8 + 3y + 8x
A 8 and 8x C 3x and 8x
B 3x and 3y D 3x, 3y, and 8
Correct answer:
C) 3x and 8x
Step-by-step explanation:
At first I thought the correct answer was D.
You may Have thought that too but that is not the correct answer.
You see 3x and 8x are both like terms because they both have x
but..
The other 3 does not have a x it has a y
I hope this helps

The Hamptons Family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute.
Part A: Define the input and output in the given scenario.
Part B: Write a function to model this situation.
Part C: How many liters of water will be left in the tank after 10 minutes
(hint: liters, not milliliters)
Answer:
The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank
We can give a letter 't' for the time, the input, and f(t) for the output
----------------------------------------------------------------------------------------------------------------
The original amount of water in the tank is 10450, so this will be the fixed constant.
The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t
The function is given f(t) = 10450 - 270t
--------------------------------------------------------------------------------------------------------------
Given, t = 10
f(10) = 10450 - 270(10)
f(10) = 7750 ml
Step-by-step explanation:
Answer:
Part A:
Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.
Part B:
Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.
Part C:
After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.

Write 16 + 32 as a product of two factors using the GCF and the distributive property.
16 + 32 = ? (4, 8, 16, or 32 are the numbers below the question mark) ( ? + ? ) (1, 2, 4, and 8 are below both of the question marks in the parentheses)
Answer:
16 (1+2)
Step-by-step explanation:
factors of 16: 1,2,4,8,16
facfors of 32: 1,2,4,8,16,32
16 x 1 = 16
16 x 2 = 32
We are required to write 16 + 32 as a product of two factors using the GCF and the distributive property.
16 + 32 as a product of two factors using the GCF and the distributive property is 16(1 + 2)
given:
16 + 32
Factors of 16 = 1, 2, 4, 8 and 16
Factors of 32 = 1, 2, 4 8, 16 and 32
The highest common factor of 16 and 32 is 16
check a factor of 16 that can multiply 16 to give 16
= 16 × 1
check a factor of 32 that can multiply 16 to give 32
= 16 × 2
So,
(16 × 1) + (16 × 2)
= 16(1 + 2)
Therefore,
16 + 32 as a product of two factors using the GCF and the distributive property is 16(1 + 2)

Sammy buys his clothes at SuperDuper Discount Store. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. What is the total amount that he will have to pay? (Omit sales tax.)
Step-by-step explanation:
I know, that's probably a lot to take in! :D
40 × 25% = 10
40 - 10 = 30
The final price of the shoes is $30.
100 × 30% = 30
100 - 30 = 70
The final price of the jacket is $70.
30 + 70 = 100
A N S W E R:
The total price of the items Sammy bought (no including sales tax) is $100.

$
00:00
Part B
How much interest would Mia pay if the simple interest rate were 5%? Enter your answer in the box.
$
Answer:
Part A: She borrowed: 3700
Part B: She would pay 555 in interest.
Step-by-step explanation:
Since, simple interest is,
Where, P is the principal amount,
r is the annual rate of interest,
t is time ( in years ),
Part A : Here, S.I. = $ 444,
t = 3 years,
r = 4 %,
Thus,
Hence, She borrowed $ 3700.
Part B :
Here, r = 5 %, t = 3 years, P = $ 3,700,
Hence, She would pay $ 555 interest.
