Answer:
0.783
Step-by-step explanation:
To find first r and then r square for the data
correlation coefficient of x and y = Cov (x,y)/std dev x * std dev Y
Cov (x,y) = E(xy) -E(x)E(y)
Hence calculations would be as follows:
x y xy
1 2 2
2 10 20
5 5 25
7 18 126
10 25 250
Mean 5 12 84.6
Cov E(xy)-E(x)E(y) 24.6
r 0.884640297
r^2 0.782588454
so answre is 0.783 after rounding off.
c = 4/5(kp + m)
Divide both sides by 4/5 or multiply by 5/4
5/4c = kp + m
Subtract m from both sides
5/4c - m = kp
Divide by k on both sides
(5/4c - m) / k = p
p = (5/4c - m) / k
Answer:
2300
Step-by-step explanation:
it just is also because the other answer is wrong and I used the one someone wrought in the comment and it worked I am doing my work on Acellus so if that is what you are doing it is wright
10 is the highest common factor
