Answer:
0.924
Step-by-step explanation:
R² = 0.854
R = √0.854
R = 0.924
Hence, the correlation Coefficient of electricity tarrif is 0.924 ; this correlation Coefficient value, depicts a strong positive correlation between machine hours and cost of electricity. And can he interpreted to mean that ; Electricity tarrif increases as machine hours increases and also decreases as machine hours decreases.

Answer:
Slope = - 1
Step-by-step explanation:
The equation is in form
,
s the slope and
is the intercept on
axis.
Hence, in
, slope is -1 and intercept on
axis is 3.
The answer is B because when yku combine like terms (x) 2/5 + 1/5 you get 3/6. Then when you simplify the equations, you turn -1/4 into -2/8 to match the 5/8. From there you just subtract 2/8 from 5/8 getting 3/8.
