Answer:
The yoga students
Step-by-step explanation:
This one is kinda easy but i took the test and got it right have a good day! :)
It is square root of 495.
Use Pythagorean theorem.
We have A and C.
Subtract 81 from 576 to get 495.
To find x, un square both sides to get
About 22.2485955
Or 22.2 or 22 depending if we round.
To solve for the margin of error:
margin of error = critical value x standard error
To compute for the critical value:
1. compute alpha: α= 1 - (confidence level/100) = 1 - .99 = 0.01
2. Find the critical probability: p = 1 - α/2 = 1 - (0.01/2) = 0.995
3. Look for the z score at the z table, in this case it is 2.58. This is your critical value.
To compute for the standard error, the formula is:
standard error = standard deviation (σ) divided by √n = 1.6 / √420 = 0.0781
Now plug in the following in the formula:
margin of error: 2.58 * 0.0781 = 0.2014 or 0.20
The answer is letter C.
3/10 + 2/6
use their lowest common multiple — which is 30 so:
3/10 -> 9/30 (multiply by 3)
2/6 -> 10/30 (multiply by 5)
then we can get the new equation of:
9/30 + 10/30 = 19/30
Answer:
Step-by-step explanation:
<em>Look at the picture</em>.
We have:
Therefore
<em>divide both sides by 2</em>
