which of the following rational functions is graphed below?
The graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2 option (D) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function:
If we take the function:
[tex]\rm f(x) = \dfrac{1}{\left(x-1\right)\left(x-2\right)}[/tex]
At x = 1 and x = 2 the function will be not defined, so this region would be hollow and as we can see in the graph of a function.
The function is not defined at x = 1 and x = 2.
Thus, the graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2.

topic: Inscribed Quadrilateral theorem in a Circle
Answer:
Step-by-step explanation:
Remark
When a quadrilateral is inscribed in a circle, the opposite angles are supplementary. x is opposite 112 degrees. Therefore x and 112 add up to 180 degrees.
Formula
x + 112 = 180 Subtract 112 from both sides.
Solution
x + 112-112 = 180 - 112
x = 68

Step-by-step explanation:
FIFO means "first in - first out". so, it is airways the oldest in the inventory that is sold. that means the newest or youngest items in the inventory remain.
the end inventory shows 70 units.
that means, all the November units (64) plus 6 of June are still there.
a.
the cost of the ending inventory is
576 + 6×8 = 576 + 48 = $624
b.
the cost of goods sold is then
1727 - 624 = $1,103
control :
196 + 483 + (59-6)×8 = 679 + 53×8 = 679 + 424 =
= $1,103

A company offers its employees free recreational activities and gym memberships. of the 200 employees, 95 employees registered for recreational activities, 80 employees registered for gym memberships, and 30 employees did not register at all. if an employee is chosen at random, what is the probability that the employee has registered for both recreational activities and gym memberships?
a.) 39/40
b.) 3/20
c.) 17/20
d.) 1/40
From the calculation, we can see that, the probability that an employee has registered for both recreational activities and gym memberships is 1/40.
What is probability?The term probability refers to the chance that an event will occur or not. The probability of an event always lies between zero and 1.
Given that;
Number that registered for recreational activities = 95
Number that registered for gym membership = 80
Number that did not register at all = 30
Total number of gym employees =200
Hence; 95 + 80 +30 =205
Number that registered for both recreational activities and gym membership
= 205 - 200 =5
The probability that an employee has registered for both recreational activities and gym memberships is; 5/200 = 1/40

For a charity initiative, 420 t-shirts were made; in the morning 1/3 of the t-shirts is sold and in the afternoon 4/7 of the remaining ones. How many shirts are left to sell at the end of the day?
1/3 * 420 = amount of t-shirts sold in the morning
1/3 * 420 = 420/3 = 140 t-shirts
140 t-shirts were sold, so remaining is 420 - 140
420 - 140 = 280 remaining t-shirts
4/7 * 280 = amount of t-shirts sold in the afternoon
4/7 * 280 = (280/7) * 4 = 40 * 4 = 160 t-shirts
160 t-shirts were sold, so remaining is 280 - 160
the remaining t-shirts = 120 t-shirts
120 t-shirts are left to sell at the end of the day

Answer:
C) 20.97 AED
Step-by-step explanation:
To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as [tex]\displaystyle E(X)=\mu=\sum xP(x)[/tex].
Here, x represents values of the random variable X, [tex]P(x)[/tex] represents the corresponding probability, and symbol [tex]\displaystyle \sum[/tex] represents the sum of all products [tex]xP(x)[/tex]. Here we use the symbol [tex]\mu[/tex] for the mean because it is a parameter. It represents the mean of a population.
In this case, the expected value of the ticket is [tex]\displaystyle E(X)=\mu=\sum xP(x)=12(0.08)+18(0.15)+20(0.31)+22(0.08)+24(0.15)+25(0.23)=20.97[/tex]
This means that Ahmad can expect to win 20.97 AED for the ticket.
