The answer is that, save from 13, all real numbers fall into the domain of (fog)(x).
So, {x|x≠13} option 4 is correct.
What is meant by domain?A function's domain is the collection of all potential inputs. For instance, all real numbers are in the domain of f(x)=x², and all real numbers are in the domain of g(x)=1/x, with the exception of x=0.
Let y = f(x) be a function where x and y are the independent and dependent variables. If a function f offers a means of successfully generating a single value y while using a value for x to that end, then that selected x-value is said to belong to the domain of f.
The result of multiplying the expression for f(x) by the expression for g(x) is (x + 7)(1/x-13).
This can be expressed much more clearly as (x + 7) (x – 13)
All real numbers, with the exception of 13, can be used to replace x in the expression in this condensed form. This is due to the fact that if we substitute 13 for x, our denominator will be equal to 0, making our formula illogical.
The answer is that, save from 13, all real numbers fall into the domain of (fog)(x).
So, {x|x≠13}
Therefore, option 4 is correct.

LC is 40°. What is the measure of arc CB?
Answers
I hope this helps you
Hi there!
[tex]\large\boxed{100^{o}}[/tex]
∠C = 40° and triangle ABC is isosceles, therefore:
∠C = ∠A = 40°
Angles in a triangle sum up to 180°, so:
180 = 40 + 40 + ∠A
180 = 80 + ∠A
100 = ∠A
Thus, arc CB has a measure of 100°.

Which of the following is the appropriate test statistic for the test?
a. t=0.05/0.73
b. t=15.5/0.73
c. t=0.05/15.5
d. t=15.5/0.05
Answers
Answer:
t = 0.05 / 0.017
Step-by-step explanation:
Given the table :
Variable ____ Estimate
Intercept 1 ____ 15.5 ____2.96
Temp 1 _______0.05 ___ 0.017
R-sq = 0.73
The test statistic for a regression test :
t = b1 / E
Where ;
b1 = slope ; E = Standard error of the slope
From the result table ;
b1 = 0.05 ;
E = 0.017
The test statistic, t = 0.05 / 0.017
The appropriate test statistic for the test is t = 0.05 / 0.017.
Calculation of the test statistic for the test:Since
Variable ____ Estimate
Intercept 1 ____ 15.5 ____2.96
Temp 1 _______0.05 ___ 0.017
R-sq = 0.73
So here the test statistic should be
t = b1 / E
here,
b1 = slope ;
E = Standard error of the slope
So,
The test statistic, t = 0.05 / 0.017

What is probability?
Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Statistics classes require a statistical calculator = 44% = 0.44
Statistics classes require a computer that has statistical software = 27% = 0.27
Of the classes that require a statistical calculator, classes also require the use of a computer = 15% = 0.15
a. P(Statistical Calculator) = 0.44
b. P(Statistical Software) = 0.27
c. P(Require a Statistical Calculator and Statistical Software) = [tex](0.44)(0.27)[/tex]
⇒ [tex]0.1188[/tex]
d. P(Require a Statistical Calculator GIVEN Require Statistical Software)

Expand 4(8y-12)......
Answers
Answer:
(4 * 8y) - (4 * 12)
Step-by-step explanation:
We have the equation 4(8y - 12) and are asked to expand, this equation can be solved through distribution, and to expand it, we need to separate the "4" to multiplying into "8y" and "-12"
Therefore :
(4 * 8y)(4 * -12)
Now this may seem correct, but we have to keep in mind that we are not multiplying both answers within the parenthesis but yet subtracting, therefore :
(4 * 8y) - (4 * 12)

Answers
Answer:
There is a 54% chance that the Jets will win the Stanley Cup.
Step-by-step explanation:
Since two hockey teams, the Winnipeg Jets and the Toronto Maple Leafs, miraculously make it to the Stanley Cup finals, where as soon as a team wins 3 games, the championship is over, and the schedule for the playoffs for home games is: Jets - Leafs - Jets - Leafs - Jets; since if the Jets are playing at home, there is a 60% chance they'll win, while if they are playing on the road, there is a 45% chance they'll win, to find the probability that the Jets win the Stanley Cup the following calculation must be performed:
(0.60 + 0.45 + 0.60 + 0.45 + 0.60) / 5 = X
2.70 / 5 = X
0.54 = X
Thus, there is a 54% chance that the Jets will win the Stanley Cup.

The circumference is just diameter x π (3.14 in this case) so 42 x 3.14 = 131.88
Answer:
B
Step-by-step explanation:
the circumference of a circle is
2×pi×r
with r being the radius (half the diameter).
2r is then the diameter.
so, in our case the circumference is

Answer:

ii) 3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.
Step-by-step explanation:
I'm going to solve these question treating these events as Venn sets.
I am going to say that:
Event A: Voting is a waste of time.
Event B: They have been abducated by space aliens.
45 believe that Voting is a waste of time
This means that [tex]A = 45[/tex]
49 believe that they have been abducted by space aliens
This means that [tex]B = 49[/tex]
42 believe both of these things
This means that [tex]A \cap B = 42[/tex]
i). How many believe neither of these things?
Total of 64.
At least one is:
[tex]A \cup B = A + B - A \cap B[/tex]
With the values we have
[tex]A \cup B = 45 + 49 - 42 = 52[/tex]
None:
[tex]64 - 52 = 12[/tex]
12 believe neither of these things.
ii). How many believe Voting is a waste of time but don't believe that they have been abducted by space aliens?
This is:
[tex]A - B = A - (A \cap B) = 45 - 42 = 3[/tex]
3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.
