Answer: x=5 and x=-1
Step-by-step explanation:
X^2-4x-5=0
(X-5) (x+1)=0
X-5=0. And. X+1=0

C
Explanation: Rewrite 18 as 3^2 * 2
REASON: Factor 9 out of 18
Rewrite 9 as 3^2
Pull terms out from under the radical
Answer: 3√2
Answer:
A. The distribution of sample means of the differences will be approximately normal if there are at least 30 years of data in the sample and/or if the population of differences in winning times for all years is normal.
Step-by-step explanation:
In other to perform a valid paired test, one of the conditions required is that, data for both groups must be approximately normal. To attain normality, the population distribution for the groups must be normal or based on the central limit theorem, the sample size must be large enough, usually n > 30. Hence, once either of the two conditions are met, the paired sample will be valid.
The correct answer is the graph in the top right corner because it is a constant function. The bottom left graph is also considered a function but is an absolute function. So both are technically correct.
