Answer:
Composition of functions is sometimes commutative.
Step-by-step explanation:
Composition of the functions is sometimes commutative.
Under certain circumstances, they can be commutative. However, this is not guaranteed.
Consider, for example, the functions:
[tex]\displaystyle f(x) = x^2 \text{ and } g(x) = x^3[/tex]
Composition of the two functions yields:
[tex]f(g(x))=(x^3)^2=x^6 \\ \\ \text{ and} \\ \\ g(f(x))=(x^2)^3=x^6[/tex]
In this case, the composition is commutative.
Composition of functions is sometimes commutative.
Commutativity refers to the ability to change the order of operations without affecting the result. In terms of functions, it means that the order in which you perform the composition matters.
For example, if we have two functions, f(x) and g(x), the composition of f(g(x)) is not necessarily equal to g(f(x)). In other words, the result of applying one function followed by another is generally different from the result of applying them in the opposite order.
This lack of commutativity is due to the fact that the output of one function becomes the input of the other.
Thus, Composition of functions is sometimes commutative.

Solve for n:

n=
Answer:
[tex]n=\frac{3f-8}{10}[/tex]
Step-by-step explanation:
So we have the equation:
[tex]\frac{3}{4}f-\frac{5}{2}n=2[/tex]
First, remove all the fractions by multiplying by the LCM of the denominator.
The LCM of 4 and 2 is 4. Thus:
[tex]4(\frac{3}{4}f-\frac{5}{2}n)=4(2)[/tex]
Distribute:
[tex]4(\frac{3}{4}f})-4(\frac{5}{2}n})=4(2)[/tex]
Simplify:
[tex]3f-10n=8[/tex]
Subtract 3f from both sides:
[tex](3f-10n)-3f=(8)-3f\\-10n=8-3f[/tex]
Divide both sides by -10:
[tex]n=\frac{8-3f}{-10}[/tex]
Divide by -1:
[tex]n=\frac{3f-8}{10}[/tex]
And this is our answer :)
n = (3f - 8)/10
Step-by-step explanation:3f/4 - ²⁾5n/2 = ⁴⁾2
3f - 10n = 8
3f - 8 = 10n
n = (3f - 8)/10

Answer:
P (X = 5) = a and P (X = 6) = 0.38 - a
Step-by-step explanation:
The sum of probabilities of all the events in a sample space is known is 1.
That is:
[tex]\sum\limits^{n}_{i=1}[P(X=x_{i})]=1[/tex]
It is provided that, the random variable X, can assume values 0, 1, 4, 5, and 6.
The incomplete probability distribution is:
X P(X = x)
0 0.26
1 0.25
4 0.11
5 __
6 __
Compute the missing probabilities as follows:
[tex]\sum\limits^{n}_{i=1}[P(X=x_{i})]=1[/tex]
[tex]P(X=0)+P(X=1)+P(X=4)+P(X=5)+P(X=6)=1\\\\0.26+0.25+0.11+P(X=5)+P(X=6)=1\\\\0.62+P(X=5)+P(X=6)=1\\\\P(X=5)+P(X=6)=1-0.62\\\\P(X=5)+P(X=6)=0.38[/tex]
Assume that P (X = 5) = a.
Here the value of a lies in the interval 0 ≤ a ≤ 0.38.
Then the value of P (X = 6) will be:
P (X = 6) = 0.38 - a
Thus, the complete probability distribution is:
X P(X = x)
0 0.26

6th: (-1/16) x (-1/2) = 1/32
7th: (1/32) x (-1/2) = -1/64

the measure of one angle of a triangle is three times the measure of a second angle. the measure of the third angle is 12 less than the sum of the other two. what are the measures of the 3 angles
PLEASEEEE HELP<333
Answer:
24, 72, and 84
Step-by-step explanation:
Let the first, second, and third angles be A, B, and C, respectively.
So, first of all, since the figure is a triangle, the three angles must total 180. Thus:
[tex]A+B+C=180[/tex]
Now, we are told that the measure of one angle (let's use A) is 3 times the measure of a second angle (B). So:
[tex]A=3B[/tex]
And the measure of the third angle (C) is 12 less than the sum of the other two (A&B). Therefore:
[tex]C=(A+B)-12[/tex]
For this equation substitute A for 3B:
[tex]C=(3B+B)-12[/tex]
Combine like terms:
[tex]C=4B-12[/tex]
So we have the following equations thus far:
[tex]A+B+C=180[/tex]
[tex]A=3B[/tex]
[tex]C=4B-12[/tex]
So, substitute A and C in for the first equation:
[tex]A+B+C=180\\(3B)+B+(4B-12)=180[/tex]
Combine like terms:
[tex]8B-12=180[/tex]
Add 12 to both sides:
[tex]8B=192[/tex]
Divide by 8:
[tex]B=24[/tex]
So, the second angle B is 24 degrees.
The first angle A is three times B. Thus, A is 3(24)=72 degrees.
And C is 12 less than the sum of them. Thus:
[tex]C=(72+24)-12\\C=96-12\\C=84[/tex]
So, our angles are:
24, 72, and 84
And we are done :)

A gym membership costs $25 to join and $14 each month. Write and use an algebraic expression to find the cost of the gym membership for 6 months.
Answer:
See below.
Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:
[tex]f(x)=14x+25[/tex]
Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:
[tex]f(6)=14(6)+25\\f(6)=84+25\\f(6)=\$ 109[/tex]

A student rides his bike to school with an average velocity of 10 miles per hour. It takes him 12 minutes to get to school. Write a function that models the student's distance from home. Use t for time in hours and d for distance. Then identify the domain and range of this situation using interval notation--label each one!
Answer:
The function is [tex]d=10t[/tex]
domain is 0 to 0.2 hour.
range is 0 to 2 miles.
Step-by-step explanation:
Given that,
Average velocity = 10 miles/hour
Time = 12 min = 0.2 hour
We need to write a function that models the student's distance from home
Using formula of distance
[tex]d=v\times t[/tex]
Where, v = velocity
t = time
d = distance
Put the value into the formula
[tex]d=10t[/tex]
This is a function.
We know that,
Domain :
Domain shows the time.
So, domain = 0 to 0.2 hour
Range :
Range shows the distance.
The range at t =0,
Put the value of t in the function
[tex]d = 10\times0=0[/tex]
The range at t =0.2 hour
[tex]d = 10\times0=0[/tex]
[tex]d=2\ miles[/tex]
So. range = 0 to 2 miles
Hence, The function is [tex]d=10t[/tex]
domain is 0 to 0.2 hour
range is 0 to 2 miles

Is "What is the area of the floor in this classroom?" a statistical question?
The answer is No
Explanation:
All statistical questions involve collecting numerical data (usually from a group of people) and then analyzing it to draw conclusions about the opinions of people of a certain phenomenon as the data varies depending on the response of each person. This process is not required to determine the area of the floor because this has a unique answer and can simply be found by measuring the height and width of the classroom and then multiplying both numbers. Also, this does not imply gathering a lot of data and the data does not vary.

Answer:

Part B: 4 significant figures
Part C: 1,450 miles
Part D: He is not correct
Step-by-step explanation:
Part A: By unit conversion, we have;
1 mile = 1,760 yards
Given that the distance from Ottawa, Canada to Jackson Mississippi is 2,552,000 yards it would best simplified into miles
Part B: The number of significant digits in the reporters estimate are the non-zero digits before the zeros in the number figure which are 2, 5, 5, and 2 or 4 significant figures
Part C: 2,552,000 yards = 2,552,000 yards/(1,760 yards/mile) = 1,450 miles
Part D: Given that the distance from Jackson to Tucson = 7,159,680 feet, we have;
1 mile = 5,280 feet
Therefore;
7,159,680 feet = 7,159,680 feet/(5,280 feet/mile) = 1,356 miles
Therefore, the claim that the distance from Jackson to Tucson which is 1,356 miles is further than the distance from Ottawa, Canada to Jackson Mississippi which is 1,450 miles is not correct because;
