Answer:
Step-by-step explanation:
-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:
Where:
is the standard deviation
is the desired margin of error.
We substitute our given values to calculate the sample size:
Hence, the smallest desired sample size is 23
The answer is C. I got this by doing a^2 + b^2= c^2. 50^2 + 16^2=c^2, 2500 + 256 = c^2, 2756 = c^2, then you take the square root of 2756 and that gives you your answer 52.50 yards. Hope this helps :D
5x + 50 +x
= 5x*2( square ) + 50
Answer: 17
Step by step : 146+2x=180
2x=34
X=17
Hey there! :D
When a fraction is still divisible by a number, then it is not in it's simplest form.
For example, 3/6.
I know for a fact that 6/3=2 <== 3 is also divisible by itself.
3/6 (3/3=1) (6/6=1)
1/2 <== simplest form.
Try the same with 2/4.
4 is divisible by 2.
4/2= 2
2/2=1
1/2 is the simplest form.
I hope this helps!
