Answer:

400

Step-by-step explanation:

$\frac{2}{3}(600) = 400$

Multiply 600 by 2 to get 1200, then divide that product by 3 to get 400.

So, 400 books were sold.

aliya0001 [1]

Answer:x=7& y= 2

Step-by-step explanation:

x+3y=13

3x+2y=25

Using elimination method

We have

3× x+3y=13......I

1×3x+2y=25....ii

3x+9y=39

3x+2y=25

7y=14

Divide through by 7

y=2

Substitute for y in equation i

x+3(2)=13

x+6=13

x=7

xxMikexx [17]

Answer:

$\frac{-5}{8}\pi =-112.5$

Step-by-step explanation:

We know that 1π rad=180°

Hence we can use a proper relation

$\pi = 180\\-5\frac{\pi }{8}=x$

Solving for x results

$x=\frac{-5}{8}*180=\frac{-5}{2}*45=\frac{-225}{2}=112,5$

Zinaida [17]

Answer:

Confidence interval: (1.95,4.45)

Step-by-step explanation:

We are given the following information:

U.S Scores

$\bar{x}_1 = 20.6, s_1 = 5.8, n_1 = 185$

Mexico Scores

$\bar{x}_2 = 17.4, s_2 = 5.8, n_2 = 86$

Formula:

Degree of freedom = $n_1 + n_2 -2 = 185 + 86 -2 = 269$

Confidence interval:

$(\bar{x}_1 - \bar{x}_2) \pm t_{critical}\bigg(\sqrt{\displaystyle\frac{s_1^2}{n_1} + \displaystyle\frac{s_2^2}{n_2}}\bigg)$

Putting the values, we get,

$t_{critical}\text{ at}~\alpha_{0.10}\text{ and degree of freedom 269} = \pm1.6505$

$(20.6-17.4) \pm 1.6505\bigg(\sqrt{\displaystyle\frac{33.64}{185} + \displaystyle\frac{33.64}{86}}\bigg)= 3.2 \pm 1.25 = (1.95,4.45)$
