PLEASE HELP!!!!!!!!!!! Kim wants to know if the number of words on a page in her math book is generally more than the number of

words on a page in her poetry book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean absolute deviation
Math 49.9 43 10.2
Poetry 41.5 42 1.1

Kim claims that because the mean number of words on each page in the math book is greater than the mean number of words on each page in the poetry book, the math book has more words per page. Based on the data, is this a valid inference? (5 points)


Yes, because the mean is larger in the math book

No, because the mean is larger in the math book

No, because there is a lot of variability in the math book data

Yes, because there is a lot of variability in the math book data

It's D, because the mean doesn't matter as much if it's only taken in a small variability. The mean was selected from 25 random pages in the book, that is why it is right.

Answer:

<h2>Yes, because the mean is larger in the math book.</h2>

Step-by-step explanation:

According to Kim's calculations

  • The mean of the Math Book is 49.9, this means there are 49.9 per page.
  • The mean of the Poetry Book is 41.5, which means there are 41.5 per page.

Remember that a mean is defined as the quotient between the sum of all elements and the total number.

According to this calculations, the Math Book has more words per page, based on its greater mean.

Therefore, the right answer is the first choice.

Solving systems of equations by substitution<br> Y=6x y=5x+7
soldi70 [24.7K]
Y=6x (1)
y=5x-7 (2)

Substitute y into (2)
(6x)=5x-7 -- subtract 5x from both sides
x=-7

Sub x into 1
y=6(-7)
y=-42

x=-7
y=-42

Step-by-step explanation:

blue line: forward with positive +2\frac{3}{4}

red line: backward with negative -4\frac{1}{4}

so the number line follows: 2\frac{3}{4} + -4\frac{1}{4} = -1 2/4
