However, in 35 of the 46 super bowls through 2012, the super bowl indicator has correctly predicted the direction of the dow jones industrial average. to determine if this is evidence that the super bowl indicator is better than simple random chance, perform the hypothesis test h0: p = 0.595 ha: p > 0.595, where p is the probability that the super bowl indicator correctly predicts the performance of the dow jones industrial average.

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.
