If the coefficient of determination for a data set containing 9 points is 1, how many of the data points must lie in the regression line for the data set? a. 6 b. 7 c. 9 d. 8

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

5+2x=a

well in order to answer the question, you have to give us the dimensions of the prism first.
