PLEASE HELP ASAP A local news show asks viewers to call in their answers to the question “Does the city need a new airport?" Two-thirds of the 240 callers say no. The same question is asked of 240 people who are contacted by phone from a random selection of local telephone numbers. Only 28% of these people answer no. Which result is probably more valid?

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

6 cars because if you have 8 and subtract 2 youll have 6 left over

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
