If FC IS RS 4430 and the BEP in unitsis 89, then contribution margin is ?

Umnica [9.8K]

Answer: RS 49.8

Step-by-step explanation:

Given the following :

Fixed cost = RS 4430

Break even point = 89 units

Recall:

Break even point in units = Fixed cost ÷ contribution margin

Therefore,

Contribution margin equals;

(Fixed cost ÷ break even point in units)

= 4430 / 89

= 49.775280

= RS 49.8

You have a 5-question multiple-choice test. Each question has four choices. You don’t know any of the answers. What is the exper

mrs_skeptik [129]

Each question has four choices, then the probability to guess a correct answer is $p= \frac{1}{4}$ and the probability to select incorrect choice is $q=1-p=1- \frac{1}{4} = \frac{3}{4}$ .

You have a 5-question multiple-choice test, then n=5. The probability that you will guess exactly three out of five questions correctly is 

 $C_n^kp^nq^{n-k}=C_5^3p^3q^{5-3}= \dfrac{5!}{3!\cdot 2!} \left( \dfrac{1}{4} \right)^3\left( \dfrac{3}{4} \right)^2=\dfrac{1\cdot 2\cdot 3\cdot 4\cdot 5}{1\cdot 2\cdot 3\cdot 1\cdot 2} \cdot \dfrac{9}{1024} =$ 
$= \dfrac{90}{1024} = \dfrac{45}{512}$ .

Can a local maximum also be a point of inflection? Explain.

myrzilka [38]

Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.
