Information provided:
Sample size, n = 30 students
P(Male), P(m) = 55% = 0.55
P(Female), P(f) = 45% = 0.45
Now,
Mean = nP(m) = 30*0.55 = 16.5 ≈ 17 students
Variance = (sd)^2 = nP(m)P(f) = 30*0.55*0.45 = 7.425 ≈ 8 students
Answer:
Step-by-step explanation:
Hi there,
The graph indicated is showing a horizontal asymptote. In fact, it is showing both a horizontal and a <em>vertical </em>asymptote.
To tell which type it is, notice where the graph "shoots off" and almost forms an imaginary straight line in one direction. Using this logic, the horizontal asymptote will be exactly horizontal, parallel to x-axis, and vertical asymptote will be exactly vertical, parallel to y-axis.
With this graph, we notice the horizontal asymptote is at y=0, where the x-axis is. The vertical asymptote is bit more difficult to determine graphically, but can definitely say it is past x=-10. We could determine it if we had the function, but that is not necessary for this question.
Study well, and persevere. If you liked this solution, leave a Thanks or give a rating!

Answer:
C. 6.4 percent.
Step-by-step explanation:
Given,
Labor force = 125 million,
The number of employed workers = 117 million,
So, the number of unemployed workers = Labor force - employed workers
= 125 million - 117 million
= 8 million,
Hence, the unemployment rate = ![\frac{\text{Unemployed employees}}{\text{Labor force}}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BUnemployed%20employees%7D%7D%7B%5Ctext%7BLabor%20force%7D%7D%5Ctimes%20100)
![=\frac{8}{125}\times 100](https://tex.z-dn.net/?f=%3D%5Cfrac%7B8%7D%7B125%7D%5Ctimes%20100)
![=\frac{8}{5}\times 4](https://tex.z-dn.net/?f=%3D%5Cfrac%7B8%7D%7B5%7D%5Ctimes%204)
![=\frac{32}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B32%7D%7B5%7D)
= 6.4%
OPTION C is correct.
Answer:
Statistic
Step-by-step explanation:
Generally, when we talk about statistic, we are talking about the characteristic of a sample. A statistic can be said to be a value which is calculated or computed from the values in a sample.
By applying mathematical functions in this case addition and division to the values present in the sample, we have what is now known as statistic.
