If they went 5 km in 1 1/2 hours what was their rate?

Answers

ratio=number of Km / number of hours

Data:
Number of Km=5 Km
Number of hours=1  1/2 hour=1.5 hour.

Ratio=5 km/1.5 hour=3.333... km/h≈3.33 km/h.

Answer; their ratio was 3.33 Km/h.
If they went five km in 1&1/2 hours then their rate would be:
(5)/(1&1/2)= 5÷(3)/(2)= 5×(2)/(3)= (10)/(3)=3(1)/(3)

so 3(1)/(3) km per hour

What would it mean if the teacher had a MAD of 0

Answers

Answer:

MAD or also called as median absolute deviation is equal to zero. This means that there is no deviation and all the values are the same.

When a given number series is sorted in ascending order, the median is the middle number and that is zero.

MAD is a way to describe variation in a data set.

When a teacher gets MAD of zero, this means all the values are zero.

It would mean that the sum of numbers is equal 0, so the mean is going to be 0 also)

After 1 month, the book club had 5 members. The number of club members doubled every month.How many members did the club have after 4 months?


[ ]

Answers

Alright, take it step by step...in month one, they had 5 members.
if the number doubles each month, then the second month they will have a total of ten members, right? in the third they will have twice the number before, or 2 times 10, 20. if you double 20, you have the number of people in the fourth month, giving you a grand total of 40.
Since you know that the number of club members doubled every month , you would multiply how much members in one month by 2 
1 month= 5  members multiply by 2
2 month= 10 members multiply by 2
3 month = 20 members multiply by 2 
4 month= 40 members

So, for each moth you multiply it by 2.
After 4 months there will be 40 members
