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
Hello there ^ _ ^
We know that 36 plates filled 1 box
if we have 1000 plates, how many box it would fill.
All we have to do is divide 1000 by 36 to find the answer.
1000/ 36 = 27.77777 or you can just say 28
I hope this help!
Circumference = π * d
π=3.14
diameter = 6
3.14 * 6 = 18.84.
The answer is A.
Hope this helped☺☺
Answer: circumference = 2Πr²
Where r= 3
Π=3.14
Therefore Circumference = 2×3.14× 3²
= 2×28.26
Circumference=56.52
Formula:
Subtitute in 3 for r.
Solve and the answer is 28.26
Answer:
1. x=-7/3 + 4y/3
2. x= 6- 3y/4
Step-by-step explanation:
to isolate the variable you simply solve for it by moving all the terms which don't contain x to the right by multiplying, subtracting, adding, and dividing
