Esther wants to know if the number of words on a page in her language arts book is generally more than the number of words on a

page in her social studies 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 Language arts 78.5 60 14.2 Social studies 68.7 65 9.8 She claims that because the mean number of words on each page of the language arts book is greater than the mean number of words on each page of the social studies book, the language arts book has more words per page. Based on the data, is this a valid inference? Yes, because there is a lot of variability in the language arts book data No, because there is a lot of variability in the language arts book data Yes, because the mean is larger in the language arts book No, because the mean is larger in the social studies book

weeeeeb [17]

Answer: x>_3.2 OR x<_ -0.75

Step-by-step explanation: first break down your compound inequality. 5x-4>_12

You first cancel out your constants by adding 4 to both sides. Now you’re left with 5x>_16 then to cancel five you have to divide on both sides by five which equals to 3.2. Then, x>_ 3.2.

Next you do your second part, 12x+5<_-4

So first cancel out the constant of 5 by subtracting 5 on both sides, making the equation 12x<_-9. Now, you divide by 12 on both sides, making it -9/12. Which effectively is -0.75. Therefor, the answer being x<_ -0.75. Add the two together x>_3.2 OR x<_0.75

Answer:

$1

max rev = 80(4) = $320

Step-by-step explanation:

let us do this in pennies  

R = (100 - x/5)(300 + x)

d/dr = <u>-2x - 200</u>

               5

(-2x-200)/5 = 0  

-2x = 200

x = 100

const2013 [10]

Answer:

3x + 2y is <to 30

(the second answer)

Step-by-step explanation:

So basically the x is going to be the first thing mentioned, so roses, which are 3$. 3x. Carnations are going to he 2nd and so therefore represented by Y. 2y.

3x + 2y (you're adding them)

It says she does not want to spend more than 30$ and so because there is no less than or equal to sign, it would be the first answer.

yan [13]

Answer:

Step-by-step explanation:

With the initial statement, when the trees  become very old, they stop flowering, it would be expected that only trees that has stopped flowering are to be considered because they are assumed to be old trees.

But with the additional information, we had to choose trees that were

no more than 240 cm tall, the choice of trees now is only those who are not more than 240 cm tall. This implies that the choice of trees to be considered now may be old or young, once they meet the required height.
