Mr. Thomas wanted to know if the amount of class time that he gave students to study affected
their test scores. The scatter plot below shows the
results,

Study Time
What kind of relationship between class study time
and test scores is shown on the scatter plot?
A. no correlation
B. positive correlation
C. negative correlation
D. positive then negative correlation

(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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
