Suppose the line of the best fit is being found for some data points that have an r-value of 0.885. if the mean of the x-coordinates is 5,768, and the mean of the y-coordinates is 8.112, what is the slope of the line to three decimal place.
a)1.245< < < < nvm thats the correct answer
b)0.803
c)0.629
d)1.589

a)1.245

Step-by-step explanation:

There is a mistake in the question, the corrected version is:

"the standard deviation of the x-coordinates is 5.768 and the standard deviation of the y-coordinates is 8.112"

The equation of a line, in general terms, is:

y = a + b*x

where b is its slope and a is its y-intercept.

In a regression, the slope can be computed as follows:

b = r * standard deviation of the y-coordinates / standard deviation of the x-coordinates = 0.885*8.112/5.768 = 1.245

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
