Answer:
(64x -11)/y
Step-by-step explanation:
Multiply 4x into the parenthesis.
60x + 4xy -11y
Divide by y.
(60x + 4x -11)/y
(64x -11)/y

Answer:
Slope = -1.71
Intercept = 22.05
Step-by-step explanation:
Equation of a line usually takes the general form :
ŷ = mx + c
Where :
m = slope or gradient
c = intercept
Inputting the data into a linear regression calculator ;
The output is : ŷ = -1.70872X + 22.04985
Comparing the output to the general formula;
The slope (m):
m = -1.70872 = -1.71(2 decimal places).
The intercept (c):
c = 22.04985 = 22.05(2 decimal places).
Part A:
Given that in a sample of 400 registered voters, 204 were democrats, i.e. n = 400, <span>
</span>The 95% confidence interval for the proportion of registered democrats voters in the population is given by:
Part B:
Given that t<span>here
are 169 million registered voters in the US, the interval for
the number of registered democrats in the population is given by
[0.461(169,000,000), 0.559(169,000,000)] = (77,909,000, 94,471,000)
