Micheal's mean score for five tests was 82. if four of those tests were 83,75,93, and 67, what was the fifth score on his test?

bezimeni [28]

Let T represent the fifth test score. The average is the sum of scores divided by their number.

... 82 = (83 +75 +93 +67 +T)/5

... 410 = 318 +T . . . . . . . multiply by 5

... 92 = T . . . . . . . . . . . . subtract 318

The fifth score was 92.

_____

One of the ways I like to work problems like these is to add the differences from the mean. Those are ...

1, -7, 11, -15

so their sum is -10.

The final score must be 10 above the mean in order for this total to be zero. 10 above the mean is 92.

You weigh a gallon of 2% milk in science class and learn that is approximately 8.4 pounds. You pass the milk to the next group,

iris [78.8K]

1 pound is 0.453592 kilograms
so 8.4 pounds is 3.81018 kilograms
You would cross multiply and make sure the units are lined up with each other

1 $\frac{1 lb}{0.453592 kg} = \frac{8.4 lb}{x}$
then you would cross multiply and get 3.81018

kifflom [539]

Recall that the short leg is the side opposite the 30 degrees angle. And the ratio of the short leg to the hypotenuse is 1:2.

Let the length of the short leg be x, then,

$\cfrac{x}{14}=\cfrac{1}{2}\\ \\\Rightarrow2x=14\\ \\\Rightarrow x=\cfrac{14}{2}=7$
