solution:
coefficient of determination = R^2 = .85 correlation coefficient, R = 0.92
Remark
Yes even though 8 is not a prime number. There is nothing that will divide into 3 or 8 the will give a whole number answer when the division is complete.
That means that 3 and 8 are prime to each other in base 10.
18. 26
19. 10
20. (26×26×26)×(10×10×10) = 17576000
21. (26×26×26) × (1×10×10) = 1757600
22. (26×25×24)+(10×9×8) =11232000
23. (25×24×1)×(10×9×8) =432000
24. 3/6 × 2/13 = 1/13
16/10 as a mixed number would be {1 6/10} or {1 3/5}. First, you figure out how many times the denominator fits into the numerator. So you see how many times ten fits into 16 (the answer would be 1) and that's your whole number. Then, you subtract the denominator from the numerator (16-10) and put our answer (5) as the numerator in the fraction next to the 1 you got in the beginning. Then, all you have to do is simplify.
EXAMPLE:
18/10
how many times does 10 go into 18? once.
1 8/10
1 4/5
