Answer:

x = 12

Step-by-step explanation:

10 - 3 ( x + 7 ) = 26

First Step: Distribute

- 3 to ( x + 7 )

= 10 - 3 x - 21 = 26

Second Step: Combine like terms

10 - 21

= - 11 - 3 x = 26

Third Step: Add from both sides

26 + 11

= - 3 x = 37

Fourth Step: Divide from both sides

37 / - 3

x = 12

No, because here mom is adding in 3.5 more pages when it say only 1.5. So she'll be able to read 30 pages because 1.5 and 20 pages of her friends is 30. So your answer is that her mom is wrong.

I hope this helped! I gave an explanation and an answer. You're Welcome!

Answer:

Confidence Interval: (21596,46428)

Step-by-step explanation:

We are given the following data set:

10520, 56910, 52454, 17902, 25914, 56607, 21861, 25039, 25983, 46929

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{340119}{10} = 34011.9$

Sum of squares of differences = 551869365.6 + 524322983.6 + 340111052.4 + 259528878 + 65575984.41 + 510538544 + 147644370.8 + 80512934.41 + 64463235.21 + 166851472.4 = 2711418821

$S.D = \sqrt{\frac{2711418821}{9}} = 17357.09$
