There are three measures of center: mean, median, and mode.

The median would be the number in the middle when the numbers are ordered.
35 45 45 60 60 70 80

The mode would be the number that occurss most frequently.
Since 45 and 60 both appear twice, you take the mean of the two, which is 52.5

The mean would be the sum of all the numbers divided by the amount of numbers.
60+70+45+60+80+35+45 = 395/7 ≈ 56.43

You could really justify any of these, but typically you would use the mean in this case because there are no outliers.

The measure of center is mean. You would be finding the average number of minutes spent studying.
To find the mean of the data you would add all of the numbers up and divide by the total amount of numbers you added.
60+70+45+60+80+35+45
=395
395/7

The length of pathway is 10 inches on map.

Step-by-step explanation:

Given,

Total distance = 350 miles

According to map,

1 inch = 35 miles

Let, x be the number of inches on map.

Therefore, using proportion;

Inch : mile :: inch : mile

1:35::x:350\\

Product of mean = Product of extreme

35*x=350*1\\35x=350\\

Dividing both sides by 35;

\frac{35x}{35}=\frac{350}{35}\\x=10

The length of pathway is 10 inches on map.

To increase an amount by 5.4% what single multiplier would you use
Rama09 [41]
I would use the decimal form of 5.4%. It is very easy to convert a percentage into a decimal. All you have to do is move the decimal point two places to the left and remove the % sign.

5.4% = 0.054

So, 0.054 would be your multiplier.
