Answer:32
Step-by-step explanation: -8*-4=32
2r2+2r−24=0
Step 1: Factor left side of equation.
2(r−3)(r+4)=0
Step 2: Set factors equal to 0.
r−3=0 or r+4=0
r = 3 or r = −4
Answer:
A.The confidence interval based on the sample of 64 data values will be more precise.
Step-by-step explanation:
Given that we take two different random samples from the same population of test scores.
The population mean and standard deviation are unknown.
The first sample has 25 data values. The second sample has 64 data values.
When sample sizes grow the confidence interval will be narrower this is due to the reason that margin of error depends on standard error which in turn is inversely proportional to square root of sample size.
So we find that A.The confidence interval based on the sample of 64 data values will be more precise.
