Answer:
d.) x/y
Step-by-step explanation:
quotient means to divide and d shows x & y getting divided
Use slope formula Y2-Y1 over X2-X1 then simply and you get the slope. After that you plug one of the points into your y=mx+b equation.
Your equation should be:
-8= ( your new slope from the slope formula)x-5
Answer:
b) 65.08
ii) 0.75
Step-by-step explanation:
x(Kg): 62 63 64 65 66 67 68
Frequency(f): 1 5 11 15 10 6 2
xf: 62 315 704 975 660 402 136
b) mean(X) = ∑xf/N = 3254/50 = 65.08
c) x - X : -3.08 -2.08 -1.08 -0.08 0.92 1.92 2.92
(x - X)²: 9.49 4.33 1.17 0.0064 0.85 3.69 8.53
ii) Standard deviation(S.D.): √(∑(x - X)²/N = √(28.0664)/50 = √0.5613
∴ S.D.= 0.75
Answer:
the answer of the equation is 44
