Answer:
you want 4 correct and 16 incorrect
there are 20 questions
each question has four answers, so
P(right answer) = 1/4
P(wrong answer) = 3/4
----
Since you want 4 correct of 20 we have a combination of 20C4
This is a binomial problem where p = 1/4, q = 3/4 and we get
(20 "choose" 4)*(probability correct)^(number correct)*(probability incorrect)^(number incorrect)
putting numbers in we get
(20c4)*(1/4)^4*(3/4)^16
This gives us
~ .189685

Step-by-step explanation:
Breakeven quantity are the number of units produced and sold at which net income is zero
Breakeven quantity = fixed cost / price – variable cost per unit
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.
Hourly wage costs and payments for production inputs are variable costs
Variable costs are costs that vary with production
fixed cost = $2450
Variable cost = $75
price = $145
(2450) / (145 - 75) = 35

Step-by-step explanation:
Answer:
$2575
Step-by-step explanation:
For this problem, we need to form an equation that represents the car salesman's weekly income. We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales. Let n represent the total amount of sales the car salesman made. So we can build the equation as follows:
f(n) = 0.025n + 700
Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.
So let's use our formula to calculate how much he made for the week given he made $75000 in sales.
f(75000) = 0.025(75000) + 700
f(75000) = 1875 + 700
f(75000) = 2575
Hence, the car salesman made $2575 for the week.
Cheers.
