<h2>Answer:</h2>

The part of the video that was not of his children is:

         85 minutes    OR   1 hour and 25 minutes.

<h2>Step-by-step explanation:</h2>

It is given that:

Ali was reviewing his family video.

The tape totaled 2 hours and 37 minutes.

Now we know that:

1 hour=60 minutes

This means that:

2 hours=2×60 minutes

i.e.

2 hours= 120 minutes

Hence, 2 hours and 37 minutes= 120+37 minutes

i.e.

2 hours and 37 minutes= 157 minutes.

Video of his children totaled 72 minutes.

This means that the part of the video not of his children is:

Total time of video-Time of video of his children

=  157-72

= 85 minutes or 1 hour and 25 minutes

2 hours and 37 minutes is 2x60+37 = 157 minutes so to get the answer subtract
157-72=85 so there was not 85 minutes or 1 hour and 25 minutes of childrens video

Given a mean of 52.3 and a standard deviation of 1.8, what is the z-score of the value 51.8 rounded to the nearest tenth?
postnew [5]
The z-score of a certain data point in the given statistical data is calculated through the equation,
                                           z-score = (x - m) / sd
where x is the data point, m is the mean and sd is the standard deviation. 
Substituting the known values,
                                           z-score = (51.8 - 52.3) / 1.8
                                           z-score = -0.277
Rounding the answer to the nearest tenth will give an answer of -0.3.

Don’t remember how to do this , ?

28. The ratio of games they won to total games played = 12: 14 = 6: 7.

29. Max's pay rate is 9.50 dollars per hour.

30. The value of n is 9.

Step-by-step explanation:

Step 1; Heather's team won 12 games out of 14. To find the ratio of games won to the total number of games we divide the number of games won to the number of games played.

The ratio of games won to games played = 12: 14, dividing both sides by 2 we simplify the ratio. So the simplified ratio is 6: 7.

Step 2; Max earns $380 for working 40 hours. So to find how much he earns an hour we divide the total money earned in n hours divided by n number of hours.

Money earned per hour = \frac{380}{40} = $9.50. So Max's pay rate per hour is $9.50.

Step 3; The given proportion is

\frac{n}{12} = \frac{18}{24}, to solve this we keep n on the left-hand side while we multiply the 12 on to the other side

n = \frac{18}{24} × 12 = \frac{3}{4} × 12 = \frac{36}{4} = 9.
