The following data show the midterm and final exam scores in an English writing class. Student 1 2 3 4 5 6 7 8 9 10 11 12 Midter
tester [92]

Answer:

The co variance of the midterm and final exam scores is 58.76.

Step-by-step explanation:

The formula to compute the sample co variance is:

Cov(x,y)=\frac{\sum(X-Mean\ of\ X)(Y-Mean\ of\ Y)}{n-1}

The values are computed in the table below.

Compute the co variance as follows:

Cov(x,y)=\frac{\sum(X-Mean\ of\ X)(Y-Mean\ of\ Y)}{n-1}\\=\frac{646.33}{12-1}\\ =58.76

Thus, the co variance of the midterm and final exam scores is 58.76.

Help me pleaseeeeeeeeeeeeeeee

We can eliminate 0.6, since that would result in a smaller shape, not a larger.

If the scale factor was 2, then each coordinate for every point on the original shape would be multiplied by 2.

For example, (3,3) would become (6,6), but it didn't.  So that rules out the scale factor of 2.

If the scale factor was 1.5, then each coordinate for every point on the original shape would be multiplied by 1.5.

For example, (3,3) would become (4.5,4,5), and that checks out.  

Then (4,4) would become (6,6), and that also checks.

And (5,3) would become (7.5, 4.5), and that looks right.

Finally, (2,5) would become (3, 7.5) and that also look good.

I'd say the scale factor is 1.5.

Find the equation of the line that is parallel to the given line and passes through the given point.
noname [10]

Answer:

y = -x + 9

Step-by-step explanation:

Since the line is parallel, the slope is -1.

y = -x + c

Substituting (0,9) into the above equation:

9 = 0 + c

c = 9

y = -x + 9
