Answer:
And the margin of error with this one:
Step-by-step explanation:
Assuming that the parameter of interest is the sample mean 
. And we can estimate this parameter with a confidence interval given by this formula:
(1)
For this case the confidence interval is given by (1.9, 3.3)
Since the confidence interval is symmetrical we can estimate the sample mean with this formula:
And the margin of error with this one:
Answer:
irrational.
Step-by-step explanation:
0.7777... repeats and does not end so it is irrational
Answer : 140
140 times 40% = 65 so the answer is 140
His average speed is 2.27 meters per second
Answer:
-2x - y = -5 in slop intercept form would be <u>y = -2x + 5 </u>
Step-by-step explanation:
-2x - y = -5
first add -2x to the left side to move it to the right side because whatever you do to one side u do to the other.
-y = -5 + 2x
divide by -1 on the whole equation
y = -2x + 5 is your answer.
