Answer:

56% decrease or -56.00%

Step-by-step explanation:

1) Find the difference between 50 and 22 as a number.

2) Divide the result from Step 1 by the starting number 50.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 50 to 22, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 50, and Y is the ending number 22 that it changed to When we enter these numbers into the formula, we get:

((22-50)/50)*100 = -56.00%

Answer:

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}

And for this case r =0.45

The % of variation is given by the determination coefficient given by r^2 and on this case 0.45^2 =0.2025, so then the % of variation explained is 20.25%.

The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.

Step-by-step explanation:

For this case we asume that we fit a linear model:

y = mx+b

Where y represent the final grade and x the math ability scores

m=\frac{S_{xy}}{S_{xx}}  

Where:  

S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}  

S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}  

\bar x= \frac{\sum x_i}{n}  

\bar y= \frac{\sum y_i}{n}  

And we can find the intercept using this:  

b=\bar y -m \bar x  

The correlation coeffcient is given by:

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}

And for this case r =0.45

The % of variation is given by the determination coefficient given by r^2 and on this case 0.45^2 =0.2025, so then the % of variation explained is 20.25%.

The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.

Answer:

D

Step-by-step explanation:

since we have a non decimal bigger than 0.1 we know exponent is positive, so we move count how many spaces we move from the last number and we get 9.01*10^5
