Yes -1 is a rational number. We can express it as a fraction of two whole numbers
One way is -1 = -1/1
Answer with explanation:
A x% confidence interval interprets the percentage of certainty that a person can believe that the true population parameter.
It is also represented as Point estimate ± Margin of error
Confidence level is proportional to the Margin of error.
- As confidence level increases the error bound increases that makes the confidence interval broader.
- As confidence level decreases the error bound decreases , making the confidence interval narrower.
Row A: x = 3
y = 2x - 3
y = 2(3) - 3 = 3 This is correct
Row B: x = 5
y = 2x - 3
y = 2(5) - 3 = 7 This is correct
Row C: x = 7
y = 2x - 3
y = 2(7) - 3 = 11 this is correct
Row D: x = 10
y = 2x - 3
y = 2(10) - 3 = 17 THIS IS INCORRECT, SO ROW D
Answer:
The answer is 3
Step-by-step explanation:
The answer is 3 because x= 15/5 = 3
