Okay so the range is the largest number - the smallest number.

So 25 - 11 = 14

The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.

So we first calculate the mean.

119 ÷ 7 = 17

Now we calculate the distance each value is from 17. (SEE ATTACHMENT)

What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.

28 ÷ 7 = 4

The Absolute Mean Deviation is 4.

I'll figure out the bottom in a minute. But this is all I got for you so far.

What is 14.36 rounded to the nearest tenth?

Vinil7 [7]

14.36 rounded to the nearest tenth is 14.4 (14.40).

Why?

Well because when rounding first we see what number we need to round. In this case it is 14.36 (3), next we look at the next number after the number which we need to round from which is 14..36 (6). If this number is 5 or MORE then we will round to the next number. But if it is LESS than 5 then we will keep it that number and add a 0 at the end. Since this number is AFTER 5 it will round up to 14.40.

So, 14.36 rounded to the nearest tenth is 14.40.

Hope I helped ya!!!

Sheila, janice, and katen, working together at the same rate, can complete a job in 3 1/3 days. Working at the same rate, how mu

pychu [463]

Answer:

Janice and Karen could do in 1 day:

20% of the job.

Step-by-step explanation:

To identify how much of the job could janice and caren do in 1 day, first, we must find how much of the job make just 1 person at the same rate:

If three persons make a job in 3 1/3 days, 1 person make the job in x:

3 persons ⇒ 3 1/3 days or 10/3 days
1 person ⇒ x

Then:

$x=\frac{1 person*\frac{10}{3}days }{3 persons}$ (we cancel the unit "persons")
$x=\frac{\frac{10}{3}days }{3}$
x = 10 days

Just a person would need 10 days to complete a job, now, we're gonna divide this value in 2 to obtain the time that need two persons to complete a job:

Time to complete a job between 2 persons = $\frac{10}{2}days$
Time to complete a job between 2 persons = 5 days

How two persons need 5 days to complete a job (in this case, the two persons are Janice and Karen), we can make a simple rule of three to obtain the percentage made in 1 day:
