It shows a positive correlation

Just go from the very left of the graph to the very right and see, if the points go up or down.

Or pick off some points to see the trend

(2,1) (3,2) and (5,4)

These points show that over time the number of typos go up with the number of pages printed.

Find the area of a parallelogram with base 15 yards and height of 21 2/3

VARVARA [1.3K]

To find the area of a parallelogram, you use the area formula:

Area = Base * Height

Then, all you have to do is substitute in your known integers and solve. Therefore:

Area = 15 * 21 2/3

When we multiply these two numbers, we get

Area = 325 square yards or yards $yards^{2}$

Find the population variance of: 4 6 8 9 9 <br><br> round to the nearest hundredth

soldi70 [24.7K]

Answer:

Step-by-step explanation:

To find the population variance, we first need the mean:

$\bar{x}=\frac{4+6+8+9+9}{5}=\frac{36}{5}=7.2$ so the mean is 7.2. To find the population variance (which is almost exactly the same as the sample variance except for a small difference in the denominators of the formula) we have to take each number minus the mean, and then square the difference. Add together all these squared numbers and then divide by the number of numbers. Like this:

$(4-7.2)^2=10.24\\(6-7.2)^2=1.44\\(8-7.2)^2=.64\\(9-7.2)^2=3.24\\(9-7.2)^2=3.24$

Add together those numbers and divide them by 5:

$\sigma=\frac{10.24+1.44+.64+3.24+3.24}{5}=\frac{18.8}{5}=3.76$
