2)x-(-24)=49
   x+24=49
   x=49-24
   x=25
3)-22=3+a
    -22-3=a
    -25=a
     a=-25
4)-46=-20-x
    x=-20+46

Hi , for the second one the answer is 25
x - [-24] equals 49
We have to  change the subtraction sign to an addition sign and the number -24 to its opposite .
25+24 equals 49
For the third one the answer is -25 because 3 plus -25 equals to -22.
For the fourth one the answer is 26
we change the sign to an addition sign and the number 26 to its opposite , the we just add .

Exhibit 18-2 Students in statistics classes were asked whether they preferred a 10-minute break or to get out of class 10 minute
tankabanditka [31]

Answer:

The mean and the standard deviation of the sampling distribution of the number of students who preferred to get out early are 0.533 and 0.82

Step-by-step explanation:

According to the given data we have the following:

Total sample of students= 150

80 students preferred to get out 10 minutes early

Therefore, the mean of the sampling distribution of the number of students who preferred to get out early is = 80/150 = 0.533

Therefore,  standard deviation of the sampling distribution of the number of students who preferred to get out early= phat - p0/sqrt(p0(1-p)/)

= 0.533-0.5/sqrt(0.5*0.5/15))

= 0.816 = 0.82

A football stadium contain 80% of its full capacity of spectators for a grand final match. At the end of the game, spectators le
nekit [7.7K]

Answer:

A. 30000

B. 12000

Step-by-step explanation:

Find out how much spectators leave in 1 minute.

1 second = 5

1 minute = 5 x 60 = 300 (60 seconds)

20 minutes = 300 x 20 = 6000

Since there were only 80% of the full capacity of spectators and after minutes it became 60%...

80% - 60% = 20%

20% = 6000

1% = 6000 ÷ 20 = 300

100% = 300 x 100 = 30000

1 minute = 300 spectators leaving

1 hour = 300 x 60 = 18000 (60 minutes)

30000 - 18000 = 12000
