What is the inverse of the function F (X) equals 2X +1
Answer: [tex]f^{-1}(x)=\frac{x-1}{2}[/tex]
Step-by-step explanation:
To find the inverse of a function start by replacing f(x) with x and replace the original x with y.
[tex]f(x)=2x+1\\x=2y+1[/tex]
Now solve for y
[tex]x=2y+1\\x-1=2y+1-1\\x-1=2y\\\frac{x-1}{2} =\frac{2y}{2}\\\frac{x-1}{2} =y[/tex]

3. Martina created this box plot to represent the number of inches of snow that fell during the winter in several different cities.
(a) What was the least amount of snowfall in any of the cities?
(b) In which quarter is the data most concentrated? Explain how you know.
(c) In which quarter is the data most spread out? Explain how you know.
Answer:
A) 5 inches of snow.
B) The fourth quarter of the box plot.
C) The first quarter of the box plot.
Step-by-step explanation:
A) 5 inches because that's where the farthest line to the left reaches.
B) The info is most concentrated in the fourth quarter of the box plot.
C) The info is least concentrated in the first quarter of the box plot.
Assume we're measuring something using numerical quantities. We put a dot above that figure in the number line for each frequency of that object we observe.
As a result, the number of total dots in the dot plot corresponds to the entire number of measurements of the values of whatever we performed.
Martina created this box plot to represent the number of inches of snow that fell during the winter in several different cities.
A) Because the longest line to the left reaches that point, the measurement is 5 inches.
B) The fourth quadrant of the box plot contains the greatest information.
C) The initial quadrant of the box plot contains the least amount of information.

A teacher wants to assign 4 of the 15 practice problems at the end of the lesson. How many different assignments are possible?
Answer:
3?
Actually I dont understand
The number of different assignments that are possible for this case when the teacher wants to assign 4 of the 15 practice problems is 1,365 ways.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!}[/tex] ways.
For this case, the teacher have to choose 4 problems out of 15 practice problems so that assignments are different.
An assignment would be different than other if the 4 questions in one assigment are not exactly same in the second assigment, and their order won't matter (assumingly).(no counter statement is given in the question's statement) against this assumption).
Those 15 problems are assumingly distinguishable (here we used general logic that each problem would be somewhat different if not fully, and thus, no two problems being indistinguishable).
Then, we can use the combinations to find the number of ways any 4 problems out of 15 practice problems available can be chosen, as shown below:
[tex]^{15}C_4= \dfrac{15!}{4! \times (15-4)!}\\\\\\^{15}C_4=\dfrac{15!}{4! \times 11!} = \dfrac{15 \times 14 \times 13 \times 12 \times 11 \times \cdots \times 2 \times 1}{(4 \times 3 \times 2 \times 1) \times ( 11 \times \cdots \times 2 \times 1)}\\\\\\^{15}C_4=\dfrac{15 \times 14 \times 13 \times 12 }{4 \times 3 \times 2 \times 1} = 1365[/tex]
Thus, the number of different assignments that are possible for this case when the teacher wants to assign 4 of the 15 practice problems is 1,365 ways.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle be A = 25.5 inches²
Let the height of the triangle be H = 6 inches
Let the base of the triangle be B
Now , area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
25.5 = ( 1/2 ) x ( 6 ) x ( B )
On simplifying , we get
3B = 25.5
Divide by 3 on both sides , we get
B = 8.5 inches
Hence , the base of triangle is B = 8.5 inches

Answer:

Step-by-step explanation:
Arc length of semicircle = [tex]\pi r[/tex] (where r is the radius)
Given:
diameter = 4 ft⇒ radius = 4 ÷ 2 = 2ft[tex]\pi[/tex] = 3.14⇒ Arc length = 2 × 3.14 = 6.28 ft
Use Pythagoras' Theorem [tex]a^2+b^2=c^2[/tex] to find the hypotenuse of the right triangle with legs 2 ft and 4 ft:
[tex]\implies 2^2+4^2=c^2[/tex]
[tex]\implies c^2=20[/tex]

Jenny has six cards.
Each card has a whole number written on it so that the smallest number is 5
the largest number is 24
the median of the six numbers is 14
the mode of the six numbers is 8
Jenny arranges her cards so that the numbers are in order of size.
5,-,-,-,-,24.
(a) For the remaining four cards, write on each line a number that could be on the card.
Mean is the ratio of the sum of data to the ample size. The remaining four cards that could be on the card are 8, 8, 16 and 22
Measure of dispersionMean is the ratio of the sum of data to the ample size. Median is the middle number after rearrangement while the mode is the most occurring number.
Given the sequence of numbers in order of size as 5, _, _, _, _ 24
Since 2 number falls in the middle and the median is 14, hence:
x +y/2 = 14
Since 8 is the mode, we can assume x = 8 in order to determine "y" as shown
8+y/2 = 14
8+y = 28
y = 16
The sequence of numbers will become 5, 8, 8, 16, _ 24 (8 was repeated twice being the mode)
The last unknown number can then be any value between 16 and 24. Using 22 as the last unknown value, the remaining four cards that could be on the card are 8, 8, 16 and 22

Let's first look only at the numerator: 5x^2 - 5
Consider this question: What do both terms have in common?
The answer is 5, both terms contain a 5, so we can factor it out.
5(x^2 - 1)
Now let's look at the denominator, considering the same question: 3x^2 + 3x
This time, both terms contain a 3 and an x.
3x(x^2 + 1)
Now we are here: [ 5(x^2 - 1) ] / [ 3x(x + 1) ]
In the numerator, the binomial factors out into (x + 1)(x - 1). There is also an (x + 1) in the denominator, so those to binomials cancel out. That leaves us with the following expression:
