To find the equation of a regression line, ý = ax + b, you need these formulas: a=TS
b = ý- až
A data set has an r-value of 0.553. If the standard deviation of the x-
coordinates is 3.996, and the standard deviation of the y-coordinates is 6.203,
what is the slope of the line to three decimal places?
A. 0.858
B. 0.356
O C. 1.165
D. 2.807

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
