The answer to the multi answer question is y = 4x + 13, and y = 3x2 - x - 1
Turn the mixed numbers into improper fractions:
-5 5/8 = - 45/8
-4 7/12 = - 55/12
Remember, when you divide by a fraction, you take its reciprocal and multiply it:
(-48/8) / (-55/12) = (-48/8) x (-12/55)
Simplify the fraction:
72/55
I think this is the answer.
Answer: The point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
Step-by-step explanation:
Let be the sample mean .
We know that the confidence interval for population mean is given by :-
, where E is the margin of error .
Given : Lower bound of the confidence interval = 0.226
Upper bound of the confidence interval =0.604
i.e.
Adding (1) from (2), we get
From (2),
Hence, the point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
