First,let's find the slope-intercept form of equation which is y=mx+b, where y and x are coordinates, m is the slope and ,c is the y-intercept
y+6.75=0.25(x-1)                                                   y=0.25(2)-6.5
y+6.75-6.75=0.25x -0.25 -6.75                            y=-6
y=0.25x-6.5   
(2,-6)  is the only correct answer I think is on the line with this equation.

Answer:

Option B and C, i.e., (-3,-7.75) and (4,-6)

Step-by-step explanation:

The given equation is

y+6.75=0.25(x-1)

We need to find ordered pairs which are on the line.

The given equation can be rewritten as

y=0.25x-0.25-6.75

y=0.25x-7

For x=2,

y=0.25(2)-7=0.5-7=-6.5\neq -6

For x=-3,

y=0.25(-3)-7=-0.75-7=-7.75

For x=4,

y=0.25(4)-7=1-7=-6

For x=7,

y=0.25(7)-7=1.75-7=-5.25\neq 5

Therefore, points (-3,-7.75) and (4,-6) are on the line. Options B and C are correct.

A political pollster wants to know what proportion of voters are planning to vote for the incumbent candidate in
s2008m [1.1K]

Answer:

90% confidence interval -> {0.4529, 0.5871}

Step-by-step explanation:

<u>Check conditions for a 1-proportion z-interval:</u>

np>10 -> 150(0.52)>10 -> 78>10 √

n(1-p)>10 -> 150(1-0.52)>10 -> 72>10 √

Random sample √

n>30 √

For a 90% confidence interval, the critical value is z=1.645

The formula for a confidence interval is:

CI = p ± z√[p(1-p)/n]

<u>Given:</u>

p = 78/150 = 0.52

n = 150

z = 1.645

Therefore, the 90% confidence interval is:

CI = 0.52 ± 1.645√[0.52(1-0.52)/150] = {0.4529, 0.5871}

Context: We are 90% confident that the true proportion of all voters who

plan to vote for the incumbent candidate is contained within the interval
