A city will soon be voting on a bond issue which will provide the necessary funds for a new middle school. The school board wants to know how likely it is that the bond issue will pass. They randomly sample three groups of 200 people and ask each person whether they are for or against the bond issue. The results are recorded in the table below. For Against
Sample #1 111 89
Sample #2 97 103
Sample #3 104 96

Based on the collected data, do you think the bond issue will pass or fail? How confident are you? Explain your reasoning using complete sentences.
Using the mean of the samples, approximately how many of the 15,000 voters would you expect to vote against the bond issue?

Step-by-step explanation:

A total of 600 people were asked.

A total of 312 people were for it.

312/600 = 0.52 = 52% were for it.

This means 100-52 = 48 % were against it.

Since more than 50% voted for it, it would most likely pass.

Since they used three separate sample groups I’d be confident that it passes.

15,000 x 48% = 7,200 would vote against it.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
