Answer:

1\frac{5}{6}-\frac{4}{6}=1\frac{1}{6}

Step-by-step explanation:

1) We have a bigger bar 1\frac{1}{6} and 4 little bars of \frac{1}{6}

2) There is a subtraction. This is why 4 little bars of \frac{1}{6} are being taken away. Look at the arrow direction

3)1\frac{5}{6}-\frac{4}{6}=1\frac{1}{6}

This year’s school population in Waterloo is 135 percent of last year’s school population. This year’s student population is 756
sp2606 [1]

Answer:560

Step-by-step explanation:

Let a be the number of students the school have last year

135% of a=756

135/100 x a=756

135a/100=756

Cross multiplying we get

135a=756 x100

135a=75600

Divide both sides by 135

135a/135=75600/135

a=560

Variance and standard deviation
kirza4 [7]

Answer: 8.3

Step-by-step explanation:

To find the variance, you want to find the mean of the data.

\frac{3+3+8+1+9+6}{6} =5

Now that we have the mean, we find the difference between each data point and the mean.

3-5=-2

3-5=-2

8-5=3

1-5=-4

9-5=4

6-5=1

With the difference, you square each and find the average.

(-2)²=4

(-2)²=4

3²=9

(-4)²=16

4²=16

1²=1

\frac{4+4+9+16+16+1}{6} =\frac{25}{3}

The variance is 8.3.
