Input:
{F(x) = 3 x + 1, 1/f = x - 1/3 f(2)}
Result:
{F(x) = 3 x + 1, 1/f = x - f(2)/3}
Alternate forms:
{3 x + 1 = F(x), 3 x = f(2) + 3/f}
{F(x) = 3 x + 1, f(2) = 3 x - 3/f}
{F(x) = 3 x + 1, 1/f = 1/3 (3 x - f(2))}
Alternate form assuming f and x are positive:
{3 x + 1 = F(x), 3 f x = f(2) f + 3}
To locate the percentile for a given observation in a data set, the data must be ___________. Select one: a. Displayed in a histogram b. Sorted and listed from the minimum to the maximum values c. Distributed symmetrically around the mean d. Summarized in a frequency distribution
Answer:
b. Sorted and listed from the minimum to the maximum values
Step-by-step explanation:
A percentile can be defined a measure that is made use of statistics.
A percentile is a statistical measure that indicates or shows comparison amongst a given set of data.
A percentile tells us the value or scores below which a percentage of a given observation in a data set falls.
In other to be able to effectively obtain the percentile if a given set of data, the following steps must be taken.
Step 1: Arrange, sort and list the values of the given the data set in order from lowest to the highest
Step 2: Multiply the percentage (also represented by P ) by total number of values in the data set( also represented by N)
Step 3: The value obtained from step 3 is know as the rank and this would helps us to find the percentile f a given data set.
The formula for calculating a percentiles is given as
= (P/100) x N,
where
P = percentile
N = number of values in a data set (sorted or arranged from lowest to highest)
n = Rank of a given value.
2. Sled kites rely on wind pressure to retain the shape of the sail. Each consists of a single square and two triangular pieces.
Kyle has made a model of a Sled kite as shown below. Show that the angles
(JUSTIFY)
Show that the angles A and B are congruent
Answer:
[tex]\angle A =\angle B =90^\circ[/tex]
Step-by-step explanation:
The diagram of the sled kite is attached below.
The central part of the kite is square.
We know by the property of a square that all its angles are congruent and equal to 90 degrees.
Therefore:
[tex]\angle A =\angle B =90^\circ[/tex]
Angles A and B are congruent.
ABC is an isosceles triangle in which ab and ac are equal if d is a the midpoint of BC prove that ABD=ADC
Answer:
Step-by-step explanation:
Given that,
ABC is an Isosceles triangle.
In an Isosceles triangle the opposite sides ( AB =AC) are equal; Their base angles ( < ABD = < ACD) are also equal to each other.
It is als given that D is the mid point of BC.
i.e., BD = CD
Therefore,
By SAS theorem of congruency of triangles,
ABD = ACD

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. What is the output of the function f(x) = x + 21 if the input is 4? When the input is 4, the output of f(x) = x + 21 is .
Answer:
When the input is 4, the output of f(x) = x + 21 is 25.
Step-by-step explanation:
The given function is
[tex]f(x)=x+21[/tex]
Here, x is input and f(x) is output.
We need to find the output of the given function f(x) if the input is 4.
Substitute x=4 in the given function.
[tex]f(4)=4+21[/tex]
[tex]f(4)=25[/tex]
So, the output value is 25.
When the input is 4, the output of f(x) = x + 21 is 25.

What is the simplified expression for 3a²+9ab+5-4a²-4ab+3
Answer:
5ab + 8 - 1a^2.
Step-by-step explanation:
Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2
Answer:
-[tex] {a}^{2} + 5ab + 8[/tex]
solution,
[tex]3 {a}^{2} + 9ab + 5 - 4 {a}^{2} - 4ab + 3[/tex]
collect like terms:
[tex]3 {a}^{2} - 4 {a}^{2} + 9ab - 4ab + 5 +3[/tex]
Simplify:
[tex] - {a}^{2} + 5ab + 8[/tex]

*I WILL MARK YOU BRAINLIEST!!!!!*
Answer:
C
Step-by-step explanation:
you were told to draw a graph
f(x) or y is 4 when x less than or equal to 3. so you must draw straight horizontal line at y = 4 start from x = 3 to the left
(fx) or y is 2 when x bigger than 3. so, 3 is not included. so you must draw straight horizontal line at y = 2 start from x = 3 to the right with empty circle first (it means 3 not included)

What is the product? One-eighth times three-elevenths 3 over 88 1 over 22 4 over 19 35 over 88
Answer:
[tex]\frac{3}{88}[/tex]
Step-by-step explanation:
Given
One-eighth times three-elevenths
Required
Solve
One-eighth means 1/8
Three-elevenths means 3/11
So, mathematically; the above expression is represented as thus:
[tex]\frac{1}{8} * \frac{3}{11}[/tex]
To solve this, we simply multiply the numerator and the denominator together.
After multiplying these together, the next is to check if the resulting can be simplified
If yes,we simplify it and if otherwise, we live it like that.
So,
[tex]\frac{1}{8} * \frac{3}{11}[/tex]
[tex]=\frac{1 * 3}{8 * 11}[/tex]
[tex]= \frac{3}{88}[/tex]
At this point, the fraction can't be simplified any further.
Hence,
[tex]\frac{1}{8} * \frac{3}{11} = \frac{3}{88}[/tex]

Answer:
The x-intercepts are (-2, 0) and (4, 0). I know this because it's written in intercept notation. To find the y-intercept we'll expand.
-(x + 2)(x - 4) = -x² + 2x + 8 so the y-int. is (0, 8). To find the rest we'll complete the square.
-x² + 2x + 8 = -(x² - 2x) + 8 = -(x -1)² + 1 + 8 = -(x - 1)² + 9 so the vertex is (1, 9) and the axis of symmetry is x = 1. This means that the domain is all real numbers and the range is y ≤ 9.
Urgent plz please please❤️

Step-by-step explanation:
We want to divide up the number 480 in a 3:5 ratio.
=> We should turn 480 into 3+5=8 portions, each portion is 480/8 = 60.
=> 480 could be divided into 2 smaller numbers that satisfy 3:5 ratio:
60x3=180 and 60x5 = 300.
Check:

The largest share is 2250/7, the smallest share is 500/7.
Find the difference.
2250/7 - 500/7 = 250
Answer:
$250
Step-by-step explanation:
2x+3x+9x= $500

In 1995 the usps approximated that they handled 1.8 x 10 pieces of mail. In 2010 the USPS reported that they handled 1.7 x 10 pieces how many more pieces of mail were handled in 1995 than in 2010
Answer:
1 piece of UPS
Step-by-step explanation:
Here, we want to know the difference in the number of pieces handled at the different times
In 1995, amount handled = 1.8 * 10 = 18 pieces
In 2000, amount handled = 1.7 * 10 = 17 pieces
The difference between what was handled in the year 2010 and what was handled in 1995 is 18 -17 = 1

Mark wants to invest 10,000 in a cd for at least 10 years the first choice is a cd that pays 4% annually and uses simple interest what is the total value after 10 years
Answer: 14000
Step-by-step explanation:
From the question, the first thing is to first calculate the simple interest (S.I). This will be:
S.I = (principal × rate × time)/100
where principal = 10,000
rate = 4%
time = 10 years
Simple interest = (10,000 × 4 × 10)/100
= 400000/100
= 4000
The total value after 10 years will be th addition of the amount invested and the interest. This will be:
= 10,000 + 4000
= 14000
If f(x) is a linear function and given f(3)=−3 and f(8)=1, determine the linear function. a.) What is the slope? (Be sure to leave your answer in reduced fraction form.) b.) What is the y-intercept? (Be sure to leave your answer in reduced fraction form.) c.) What is f(x)? f(x)=
Answer:
slope is 4/5
y intercept is -27/5
f(x) = 4/5x -27/5
Step-by-step explanation:
The slope is
f(8) - f(3)
----------------
8-3
1 - -3
------------
8-3
1+3
------------
5
4/5
We can use the slope intercept form to find the y intercept
y = mx+b where m is the slope and b is the y intercept
y = 4/5x +b
Using the point (8,1)
1 = 4/5(8)+b
1 = 32/5 +b
Subtract 32/5 from each side
5/5-32/5 = b
-27/5 = b
y = 4/5x -27/5
f(x) = 4/5x -27/5

find the zeros of quadratic polynomial X2 - 2x - 8
Answer:
The zeroes of a polynomial is the value of x when the polynomial is set to 0.
We can write x² - 2x - 8 = 0. This factors to (x - 4)(x + 2) = 0 and using Zero Product Property the solutions are x = 4, x = -2.
What is the largest integer $n$ such that $7^n$ divides $1000!$ ?
Answer:
The correct answer is
n = 3038
Step-by-step explanation:
Where we have;
We note that 1000! = An even number
Since Even × Even = even
Even × Odd = Even
Also, 7ⁿ is an Odd number since odd × odd = odd
Therefore 7ⁿ will divide 1000! with some fractions as follows;
1000! divided by 7ⁿ
When 7ⁿ = 1000!
log(7ⁿ) = log(1000!) = log(4.02×10²⁵⁶⁷)
n·log(7) = 2567.604
n = 2567.604/(log(7)) = 3038.23
Therefore, the largest integer n such that 7ⁿ divides 1000! = 3038
Which gives, 1000! ÷ 7³⁰³⁸ = 1.5733.

Apex
The percent increase in Soraya's monthly earnings is 2.5%
What is Percent Increase?Increase expressed as a percentage is referred to as a percentage increase. When comparing growth in a quantity through time, from its beginning value to its ultimate value, the percentage increase formula is utilised.
Given:
Soraya earned $40 in October.
She earned $50 in November.
Change in amount= 50- 40= $10
