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>
Step-by-step explanation:
Picture############
17 . Find the values of g(9) and h(-14) and add them together.
The function equations are given to find their values substitute 9 in g(x) and -14 in h(x)
20. They said f(x) = 2x + 9 and f(x) = 15 , which means they are equal to each other.
So write them as 2x + 9 = 15 , and solve the equation to find the value of x.
25. Here all you have to do is substitute 4 into the f(x) equation to find f(4)and you will have your answer.
Hope this helped!
