Edward had 100 newspapers to deliver on his paper route. he had already delivered 25 of them when 2 of his friends agreed to him deliver the remaining newspapers. if edward and his friends each delivered an equal number of newspapers, how many newspapers did edward deliver in all?

Edward delivered 50 newspapers in all.

Step-by-step explanation:

Given:

Total number of newspapers = 100

Newspapers delivered by Edward initially = 25

Newspapers left = 100 - 25 = 75

Now, 2 of his friends join. So, there are 3 persons now to deliver the remaining 75 newspapers.

So, number of newspapers delivered by 3 persons = 75

Therefore, number of newspapers delivered by each person = .

So, Edward and his two friends delivered 25 newspapers each.

Hence, the total newspapers Edward delivered = 25 + 25 = 50.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
