Since the denominators are already equal to each other, all you have to do is add the numerators.
Hi

Answer:
domain: {-7, -3, 0, 5}
range: {-5, -2, 1, 2}
Step-by-step explanation:
The domain of this set of ordered pairs is the set of input values (x-coordinates): {-7, -3, 0, 5}, and the range is that of output values (y-coordinates): {1, 2, -2, -5} or {-5, -2, 1, 2}.
Answer:
The minimum sample size to have this margin of error is n = 897.
Step-by-step explanation:
We have to estimate a parameter with a confidence interval. The confidence level is 95% and the margin of error is 0.5 days.
The population standard deviation is 7.64 days.
The critical value of z for a 95% confidence interval is z=1.96.
We have to calculate the minimum sample size.
To do that, we use the margin of error formula in function of n:
The minimum sample size to have this margin of error is n = 897.
