Answer:
So the answer for this case would be n=67 rounded up
Step-by-step explanation:
Information given
represent the sample mean for the sample
population mean
represent the sample standard deviation
n represent the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =400 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 98% of confidence interval now can be founded using the normal distribution. And the critical value would be
, replacing into formula (b) we got:
So the answer for this case would be n=67 rounded up
Answer:
Step-by-step explanation:
add 9 to both sides.
then divide by 1.5
so p > 8
number your number line: 2,4,6,8,10
draw a circle at 8 and the line to the right since p>8
Answer:
The answer to the first one is number 2
Step-by-step explanation:
They are parralel because they do not cross either in the front or in the back
V=150.8
V=3.14*36*h/3
V=113.04*4/3
V=452.16/3
V=150.72
Answer:
3(5+x)
Step-by-step explanation:
Another expression that can equal 15+3x is 3(5+x)
<u>Use Distributive Property:</u>
3(5+x)
=15 + 3x.
I wish you the best of luck, and hopefully this is an option on your homework!
