Which function is the inverse of f(x) = (x − 3)3 + 2?
Answer: f = 3x -7 / x
Step-by-step explanation:
fx=(x−3)(3)+2
Step 1: Divide both sides by x.
fx/x = 3x -7 / x
f = 3x -7 / x
Answer: f = 3x -7 / x

Which expression represents the phrase below?
3 fewer than a number, P
3-p
В
p=3
C
3 +p
D
P-3
Answer:
D) P - 3
Step-by-step explanation:
"fewer than" a number means "less than" a number. So "3 fewer than" means "subtract 3" from the number.
⇒ P - 3
An ordinary (falr) dle is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a dle is rolled twice in succession
and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 8.
Event B: The sum is divisible by 5.
Write your answers as fractions.
(a) P(X) =
(b) P(B) =
By finding the number of outcomes that meet each criteria, we will see that the probabilities are:
A) P = 0.25B) P = 7/36 = 0.194How to find the probability?
We know that the fair die has 6 outcomes, so if we roll it twice, there are a total of:
6*6 = 36 outcomes.
To find the probability of getting a given event, we need to find the number of outcomes that make the event true.
A) The sum is greater than 8.
The outcomes that make this true are:
first roll second roll sum
4 5 9
4 6 10
5 5 10
5 6 11
6 3 9
6 4 10
6 5 11
6 6 12
3 6 9
So there are 9 outcomes whose sum is greater than 8, so the probability to getting this event is:
P = 9/36 = 0.25
B) The sum is divisible by 5.
The sum must be 5 or 10, the outcomes that give that are:
first roll second roll sum
1 4 5
2 3 5
3 2 5
1 4 5
4 6 10
5 5 10
6 4 10
There are 7 outcomes, so the probability is:
P = 7/36 = 0.194

Which interval notation represents the set of all numbers less than or equal to -6 or greater than or equal to -2
Answer: 1≤x<12
Step-by-step explanation:
The values that are greater than or equal 1 but less than 12 are values ranging from 1 to 11 i.e {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}. Note that 1 is included because the number is greater than or equal to 1 (1 included) and less than 12(12 not included).
x≥1 and x< 12
if x≥1, it means 1≤x
combining both inequality
1≤x and x<12
1≤x<12
The interval notation that represent the set S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} will be given as S = {x: 1≤x<12}

theatre members, and 30 members of science club. The researchers want to get 20
respondents out of these organizations. Identify the samples to be taken in each
organization.
⚘Refer to the attachment for solution!!~
The sample to be taken in each organization such as 2.6 in the taekwondo club, 5.3 in the math club, 8 in the drama club, and 4 in the science club.
Total members of taekwondo club = 20
Total members of math club = 40
Total members of drama club = 60
Total members of science club = 30
The researchers want to get 20 respondents out of these organizations.
What is the stratified sampling method?The stratified sampling method is the process of dividing members of data into homogenous subgroups before sampling.
The total number of members = 150
For taekwondo club
= Total members of taekwondo club /total number of members × 20
= 20/150 × 20
= 2.6
For math club
= Total members of math club/total number of members×20
= 40/150 × 20
= 5.3
For drama club
= Total members of drama club/total number of members × 20
= 60/150 × 20
= 8
For science club
= Total members of the science club/total number of members × 20
= 30/150 × 20
= 4
Therefore, The sample to be taken in each organization such as 2.6 in the taekwondo club, 5.3 in the math club, 8 in the drama club, and 4 in the science club.

i once met six siblings whose ages are 6 consecutive whole numbers. i asked each of them the question how old is your oldest sibling. which of the following could not be the sum of their answers.
A. 95
B. 125
C. 167
D. 205
E. 233
The consecutive ages of the siblings mean that each sibling is a year older than the younger sibling
All the options cannot be the sum of their ages
How to determine the sum of their ages
Represent the age of the smallest sibling with x.
So, the sum of their ages is:
[tex]Sum =x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5[/tex]
Evaluate the like terms
[tex]Sum =6x + 15[/tex]
When the sum is 95 (from the options), we have:
[tex]6x + 15 = 95[/tex]
Subtract 15 from both sides
[tex]6x = 80[/tex]
Divide by 6
[tex]x = 13.3[/tex] -- this is not an integer
When the sum is 95 (from the options), we have:
[tex]6x + 15 = 125[/tex]
Subtract 15 from both sides
[tex]6x = 110[/tex]
Divide by 6
[tex]x = 6.875[/tex] -- this is not an integer
When the sum is 167 (from the options), we have:
[tex]6x + 15 = 167[/tex]
Subtract 15 from both sides
[tex]6x = 152[/tex]
Divide by 6
[tex]x = 25.33[/tex] -- this is not an integer
When the sum is 205 (from the options), we have:
[tex]6x + 15 = 205[/tex]
Subtract 15 from both sides
[tex]6x = 190[/tex]
Divide by 6
[tex]x = 31.67[/tex] -- this is not an integer
When the sum is 233 (from the options), we have:
[tex]6x + 15 = 233[/tex]
Subtract 15 from both sides
[tex]6x = 218[/tex]
Divide by 6
[tex]x = 36.33[/tex] -- this is not an integer
Hence, all the options cannot be the sum of their ages

17. Observe the figure and name the following
a) Vertices of the polygon
b) Two pairs of adjacent sides
c) Two diagonals
d) Sides of the polygon
By using the image of the polygon and the definition for the parts, we can see that:
a) A, B, C, D, and E.b) DC and CB, AE and ED.c) AD, BEd) AB, BC, CD, DE, and EA.How to identify the parts of the figure?a) The vertices are the points where two sides connect, in this case, each letter represents a different vertex, so the vertices of the polygon are A, B, C, D, and E.
b) Adjacent sides are any pair of sides that are connected by a vertex.
For example, DC and CB are connected through vertex C, so these are adjacent sides.
Another pair can be BA and AE.
c) Diagonals are the segments between two non-consecutive vertices.
For example, E and D are consecutive vertices (because there are next to each other). And A and D are non-consecutive vertices.
Then AD is a diagonal. Another example can be EB.
d) The sides of the polygon are the segments between consecutive vertices, in this case, the sides are:
AB, BC, CD, DE, EA.
