Twenty types of beef hot dogs were tested for calories and sodium content (mg). the hot dogs average 156.85 calories with a standard deviation of 22.64, and the sodium level average 401.15 mg with a standard deviation of 102.43 mg. the correlation given as r = 0.887. the equation of the lsrl predicting sodium level from number of calories is:

y = -228.29 + 4.013x

Step-by-step explanation:

Defining

x: Quantity of calories in the beef hot dogs

y: Content of sodium in the beef hot dogs

The least squares regression line equation is:

Where

Then the regression’s equation is:

y = -228.29 + 4.013x

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
