<u>Functions</u>
In a function, an independent variable, let's call it x is related to a dependent variable y and it can be expressed as:
y = f(x)
Let's consider the functions given in the question, where the equation that represents a company's yearly sales is:
And the equation that represents the same company's yearly expenses is:
The company's profit function P(x) can be found as the difference between S(x) and E(x), thus:
Operating:
Simplifying, the profit function for this company is:
The graph would not make a parallelogram.
Answer:
Step-by-step explanation:
Let X be the random variable for the time needed to grade a randomly chosen first examination paper
X is N(5, 4)
a)
Time taken=11.00-6.50=4hours 10 min=25/6 hours
P(X<25/6) =P(Z<
=0.5-0.0832=0.0168
b) Time >11.10-6.50 = 4 hours 20 mint = 13/3 hours
P(X>13/3) = P(Z>-0.16) = 0.5636
I hope your having a good day. i don’t know the answer but i hope you find it soon
Answer:
It is D.
