Question

1073 8 6 ON 10 - 5 15 IC -2 -6 -8 -70 Write the equation of the line shown. Be sure to use the correct variable. Equation:

Answer 1

1)

The equation of line is given by the formula

y = mx + c

Where m = slope

c = y-intercept (constant)

The line shown is parallel to x-axis . Here we see that no matter what value of 'x' y remains constant at -9. So a change in 'x' brings no change in y. So the slope is '0'.

The constant is -9.

y =0x + (-9)

y = -9

2)

Sample size

n = 550

x: no. of voters in sample voted for Brown

x = 252

$1595530215381_blob.png$ = x /n

Sample proportion = 0.45818

out of 550, we would expect 45.82% to vote for Brown. Therefore assuming this true for entire total of voters , out 6600 we would expect 6600* 45.82% to vote for Brown

Expected for brown = 3024
