Answer:
12x⁶+24x⁵-180x⁴/ 30x³+240x²+450x
Step-by-step explanation:
(x-3)(x+5)=x²+2x-15
12x⁴(x²+2x-15)= 12x⁶+24x⁵-180x⁴
(x+3)(x+5)=x²+8x+15
30x(x²+8x+15)= 30x³+240x²+450x

Step-by-step explanation:
Confidence interval is the range the true values fall in under a given <em>confidence level</em>.
Confidence level states the probability that a random chosen sample performs the surveyed characteristic in the range of confidence interval. Thus,
90% confidence interval means that there is 90% probability that the statistic (in this case SAT score improvement) of a member of the population falls in the confidence interval.
