Answer:

If we convert the percentages into numbers of students, including the margin of error:

Group 1: 40-49 (earlier) (31%-39%)

Group 2: 21-30 (same) (16%-24%)

Group 3: 45-55 (later) (35%-43%)

Group 4: 3-12 (no opinion) (2%-10%)

Interval estimate for group 1 is 40-49 students, and for group 3 is 45-55 students. The earlier group 1 could persuade the no opinion group 4 to join them. This would change the interval to 43-61, compared to 45-55 for group 3. In percentages this comes to 34%-47% approx.

What is equivalent to the polynomial (4x+3)(3x-8)
expeople1 [14]
The equivalent polynomial is 12x^2 -23x - 24.

You can get this by multiplying the two parenthesis by each other.

 First start by multiplying the two front numbers:
4x * 3x = 12x^2

Then multiply the outermost numbers:
4x * -8 = -32x

Then multiply the innermost numbers:
3x * 3 = 9x

Then multiply the last numbers: 
3* -8 = -24

Now combine all of them to get the above polynomial.
