Answer:
For this exercise, we need to add to the $200 the cost of the hours the DJ has been working
If each hour costs 12.50 $ and he worked 8.5 hours, we can just multiply to see the price of their work: 12.5 * 8.5 = $106.25
Now, we can do the sum: 200 + 106.25 = $306.25
Answer:
Probability that randomly selected 4 persons all have insurance is = 0.1897
Step-by-step explanation:
Given that the probability of having an insurance equals 66%=0.66
Thus
Probability that person A has insurance = 0.66
Probability that person B has insurance = 0.66
Probability that person C has insurance = 0.66
Probability that person D has insurance = 0.66
Probability that randomly selected 4 persons all have insurance is
Answer:
The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>
Step-by-step explanation:
As the domain of f(x) is the set of all real values except 7. So it can be written as follows:
Domain of f(x) = { x ∈ R | x ≠ 7}
As the domain of g(x) is the set of all real values except -3. So it can be written as follows:
Domain of g(x) = { x ∈ R | x ≠ -3}
It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.
So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Answer:
=3(x+8)(x+1)
Step-by-step explanation:
3(x^2+9x+8)
3(x^2+8x+1x+8)
3[(x^2+8x)+(1x+8)]
3[x(x+8)+1(x+8)]
=3(x+8)(x+1)
