Answer: You must rearange 3 3/4 into an improper fraction to make the subtraction easier.

Step-by-step explanation:

(this is a little long bear with me :3)

3 and 3/4ths into a improper fraction would be: 15/4

looking at 15/4 and 7/8 notice how the denominators are 4, and 8. both are common denominators. so we multiply 4x2 to make 4, into 8. and whatever we do to the bottom, we do to the top.

15x2 30

---------- = ------

4x2 8

our new fraction is 30/8.

do the subtraction..

30 7 23

---- - --- = --- that then turns into a mixed number, which is:

8 8 8

2 7/8.

hope this helped! :)

What is the mean, median, mode, and range of 8, 35, 10, 12, 14?

Ivan

answer:

mean: 15.8

median: 12

mode: no mode

range: 27

step-by-step explanation:

first know how to find each of the above and what they are
mean = (avg) add all the numbers, then divide by the number of numbers
median = the middle number from increasing order
mode = the one that repeats the most
range = the difference between the largest and smallest number

8, 35, 10, 12, 14

mean

8 + 35 + 10 + 12 + 14 = 79

there are five numbers

79 / 5 = 15.8

median

put them from smallest to largest

8, 10, 12, 14, 35

12 is the median OR the middle number

mode

no number repeat, so no mode

range

35 - 8 = 27

In a survey of 100 people, some of them jog for exercise, some of them ride a bike, some do both, and 15 do not jog or ride a bi

Answer:

Bike alone = 39

Step-by-step explanation:

Given that:

Total number = n(T) = 100

Jog= n(J)

Bike = n(B)

Bike and jog = n(BnJ) = 21

Number who jog = 46

Jog alone = 46 - 21 = 25

Neither jog nor bike = 15

Let bike alone = x

Hence,

Jog alone + bike alone + jog and bike + none of the two = 100

25 + x + 21 + 15 = 100

x = 39
