Answer: 25 computers will be selected
Step-by-step explanation:
Where: Z -value at 95% confidence = 1.96; SD = Standard deviation = 10 minutes; N = Sample size; Margin error = 4 minutesSubstituting;4 = 1.96*10/Sqrt (N)Sqrt (N) = (1.96*10)/4 = 4.9N = 4.9^2 = 24.01 ≈ 25
Answer:
The chemical reaction is due to chemical change in the chemicals within the light stick so it shows off color.
Step-by-step explanation:
The chemicals in the light stick interact with each other. This cause them to come together and give off a color of light.
Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
Therefore, a=6
u is the opposite side to the 90° angle, therefore
on the other hand, v is the opposite side to the 30° angles, so
If you don't include the outlier (50) then it is 79.7
Total number of integers = 5
median
= (5+1)/2 th observation
= 3 rd observation
therefore the 3rd number = 13
now let the other number be x
total sum = 1+3+13+x+22 = 39+x
ATQ
(39+x)/5 = 16
39+x = 80
x = 41
the numbers are -
1,3,13,22,41
