The following information are given. Correlation between x and y= 0.979 mean of the values of x= 40.35 grams mean of the values of y= 662.88 calories standard deviation of the values of x= 27.99 grams standard deviation of the values of y= 324.90 calories The intercept of the least-squares regression line is:

The intercept of the least squares regression line is: 662.83

Step-by-step explanation:

An image solution is attached for explanation.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
