In a class of 25 students, 15 of them have a driver's license. If ten students are randomly selected, what is the expected numbe
1 answer:
Answer:
<em>Expected number of students would have a driver's license = 6</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data In a class of 25 students, 15 of them have a driver's license
The sample proportion
Let 'X' be the binomial distribution
Given sample size 'n' = 10
<em>mean of the binomial distribution or expected number of students would have a driver's license</em>
μ = n p
= 10 × 0.6
= 6
<u><em>Conclusion</em></u>:-
<em>Expected number of students would have a driver's license = 6</em>

You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that
![x^{2} - 4 [(x-4)^{2}] =16 ](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-%204%20%5B%28x-4%29%5E%7B2%7D%5D%20%3D16%0A%20)
expand, collect like terms, factor to find x, then plug x value back into original equation to find y

Answer:
The 3 lines are parallel.
Step-by-step explanation:
To draw the lines with the slope of 1/3 choose any point and mark it, then go up 1 square and right 3 squares and mark that point. Draw a line connecting those 2 points. Now choose another point and do the same thing. Then once more. Lines with the same slope are parallel.
