Answer: Option D
D. 41
Step-by-step explanation:
A value [tex]x_i[/tex] is considered an outlier if
[tex]x_i> Q_3 + 1.5IQR[/tex]
or
[tex]x_i <Q_1 - 1.5IQR[/tex]
Where
[tex]Q_3[/tex] is the third quartile
[tex]Q_1[/tex] is the first quartile
IQR is the interquartile range.
[tex]IQR = Q_3-Q_1[/tex]
In this case:
[tex]Q_3=92\\Q_1=72[/tex]
So
[tex]IQR = 92-72 =20[/tex]
[tex]Q_3 + 1.5IQR = 92 + 1.5*20 = 122[/tex]
[tex]Q_1 - 1.5IQR=72-1.5*20=42[/tex]
Then the outlier values will be all those greater than 122 or less than 42
Therefore the answer is the option D.
if f(x)= 5 ^ x + 2x and g(x)= 3x - 6, find (f+g)(x)
Answer:
(f+g)(x) is 5^x + 5x - 6
Step-by-step explanation:
To find (f + g)(x), we are merely adding up all the terms present in both
f(x)= 5^x + 2x and g(x)= 3x - 6. 5^x is unique and cannot be combined with any other term. 2x and 3x can be combined to obtain 5x. -6 is unique.
Thus, the sum (f+g)(x) is 5^x + 5x - 6.
Answer:
[tex]5^x+5x-6[/tex]
Step-by-step explanation:
[tex]f(x)=5^x + 2x[/tex]
[tex]g(x)= 3x - 6[/tex]
[tex](f+g)(x)[/tex]
[tex]f(x) + g(x)[/tex]
[tex]5^x+2x+3x-6[/tex]

Find the indicated term of the given geometric sequence. a1 = 14, r = –2, n = 11
Answer:
[tex]a_{11} = 14336[/tex]
Step-by-step explanation:
The general formula for the twelfth term of a geometric sequence is:
[tex]a_n = a_1(r)^{n-1}[/tex]
Where [tex]a_1[/tex] is the first term and r is the common ratio
In this case we know that:
[tex]a_1 = 14\\r=-2[/tex]
The equation is:
[tex]a_n = 14(-2)^{n-1}[/tex]
So for [tex]n = 11[/tex] we look for [tex]a_{11}[/tex]
[tex]a_{11} = 14(-2)^{11-1}[/tex]
[tex]a_{11} = 14(-2)^{10}[/tex]
[tex]a_{11} = 14336[/tex]
Answer:
[tex]11^{th}[/tex] term = 14336
Step-by-step explanation:
We are given the first term [tex] a _ 1 = 1 4 [/tex] and common ratio [tex] r = - 2 [/tex] of a geometric sequence and we are to find the [tex]11^{th}[/tex] term of this sequence.
We know that the formula to find the [tex]n^{th}[/tex] term in a geometric sequence is given by:
[tex]n^{th}[/tex] term = [tex] a r ^ { n - 1 } [/tex]
Substituting the given values in the above formula:
[tex]11^{th}[/tex] term = [tex]14 \times(-2)^{11-1}[/tex]
[tex]11^{th}[/tex] term = [tex]14 \times(-2)^{10}[/tex]
[tex]11^{th}[/tex] term = 14336

Which second degree polynomial function has a leading coefficient of -1 and root 4 with multiplying 2?
the population of a city has increased by 15% since it was last measured. If the current population is 59.800, what was the previous population?
Answer:
about 50 000 i think sorry if this didnt hep
Step-by-step explanation:
To calculate the previous population before a 15% increase that resulted in a current population of 59,800, we use the formula: Previous Population = Current Population / (1 + Percentage Increase), which yields a previous population of approximately 52,000.
Explanation:The question pertains to determining what the previous population of a city was before it experienced an increase of 15%. Given that the current population is 59,800, we can calculate the previous population using the formula:
Current Population = Previous Population * (1 + Percentage Increase)
To find the Previous Population, we rearrange this formula:
Previous Population = Current Population / (1 + Percentage Increase)
By substituting in the given values:
Previous Population = 59,800 / (1 + 0.15)
Previous Population = 59,800 / 1.15
Previous Population = 52,000 (approximately)
Therefore, the previous population of the city was around 52,000 inhabitants before the 15% increase.
13.5 is 15% of what number?
Answer:
90
Step-by-step explanation:
13.5/.15
To solve this you must use a proportion like so...
[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]
15 is a percent and percent's are always taken out of the 100. This means that one proportion will have 15 as the part and 100 as the whole
We want to know out of what number is 13.5 15% of. This means 13.5 is the part and the unknown (let's make this x) is the whole.
[tex]\frac{13.5}{x} =\frac{15}{100}[/tex]
Now you must cross multiply
13.5*100 = 15*x
1350 = 15x
To isolate x divide 15 to both sides
1350/15 = 15x/15
90 = x
This means that 15% of 90 is 13.5

Which system below has no solution?
y = 4x and y = 2x - 3
y = -4x and y = 2x - 3
y = -4x and y = 2x + 3
y = -4-x and y = 2x - 3
it is multiple choice
The system of equations with y = -4x and y = 2x + 3 has no solution.
Explanation:The system of equations with y = -4x and y = 2x + 3 has no solution. To determine this, we can set the two equations equal to each other and solve for x:
-4x = 2x + 3
Adding 4x to both sides, we get:
0 = 6x + 3
Subtracting 3 from both sides, we get:
-3 = 6x
Dividing both sides by 6, we get:
-1/2 = x
Substituting x = -1/2 back into either equation will result in a false statement, indicating that the system has no solution.

a line in the xy- plane has the equation y=kx, where k is a constant. The line passes through the point (1,n) and (n,16). which of the following could be the value of n?
A)1
B)2
C)4
D)8
Answer:
Option C) 4
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]
In this problem
The equation of the line represented a direct variation
The value of k is equal to [tex]k=y/x[/tex]
we have the points
(1,n) and (n,16)
so
[tex]k=n/1[/tex]
[tex]k=16/n[/tex]
equate
[tex]n/1=16/n[/tex]
solve for n
[tex]n^{2}=16\\ \\n=(+/-)4[/tex]
therefore
The value of n could be 4 or -4
To find the value of n, substitute the given points into the equation y=kx and solve for n. The possible value of n is 4.
Explanation:To find the value of n, we need to use the given points and equation. Since the line passes through (1,n), we can substitute these values into the equation y=kx to get n=k(1) or n=k. Similarly, substituting the values (n,16) into the equation gives us 16=k(n). By equating these two equations, we can solve for k and n.
Using substitution, we have n=16/n. Solving this equation by multiplying both sides by n, we get n^2=16. Taking the square root of both sides, we have n=±4. Therefore, the value of n that could be possible is 4.

mark me as the brainliest plz
Given 4 yards of ribbon and each package requires 2/3 yard, Kris can wrap 6 packages.
Explanation:This question is about dividing total resources, in this case, ribbon, by the amount needed for each unit, in this case, a package. Kris has 4 yards of ribbon, and each package requires 2/3 yard of ribbon to wrap. To find out how many packages Kris can wrap, we need to do a division: total yards of ribbon ÷ yards of ribbon per package.
The equation for this would be: 4 ÷ 2/3. When we divide by a fraction, we multiply by its reciprocal. The reciprocal of 2/3 is 3/2, so we set up the equation like this: 4 x (3/2).
The answer to this equation is 6. Hence, Kris can wrap 6 packages with 4 yards of ribbon.

Complete the missing parts of the table for the following function
The missing parts of the table for [tex]\( x = 0 \)[/tex] and [tex]\( x = 3 \)[/tex] are 1 and 216, respectively.
Let's solve for the missing values step by step.
The function given is [tex]\( y = 6^x \)[/tex]. This means that for each value of [tex]\( x \)[/tex], [tex]\( y \)[/tex] will be [tex]\( 6 \)[/tex] raised to the power of [tex]\( x \)[/tex].
Step 1: Solve for [tex]\( y \)[/tex] when [tex]\( x = 0 \)[/tex]
The exponent law states that any number raised to the power of 0 is 1. Therefore:
[tex]\( y = 6^0 = 1 \)[/tex]
Step 2: Solve for [tex]\( y \)[/tex] when [tex]\( x = 3 \)[/tex]
To find [tex]\( y \)[/tex] when [tex]\( x = 3 \)[/tex], we simply raise 6 to the power of 3:
[tex]\( y = 6^3 = 6 \times 6 \times 6 = 216 \)[/tex]
So, the completed table should look like this:
[tex]$\begin{array}{rrrrrrr}x & -2 & -1 & 0 & 1 & 2 & 3 \\ y & \frac{1}{36} & \frac{1}{6} & 1 & 6 & 36 & 216\end{array}$[/tex]

A sporting goods store is offering a 10% discount on in-line skates that normally cost $110.99. How much will the in-line skates cost with the discount, not including tax?
The in-line skates will cost $99.891 with the discount.
Explanation:To find the cost of the in-line skates with the discount, we need to calculate the amount of the discount first. The discount is 10% of the original price, which is $110.99. To calculate the discount amount, we can multiply the original price by 0.10. The discount would be $110.99 x 0.10 = $11.099. The discounted price would be the original price minus the discount amount, so the discounted price would be $110.99 - $11.099 = $99.891.
A regular convex polygon has eight sides. What is the measure of an exterior angle?
Answer:
The measure of one exterior angle is 45 degrees.
Step-by-step explanation:
The formula to find exterior angle of and shape is 360 degrees divided by n (number of sides the shape has). 360 divided by 8 = 45 degrees.
Answer:
Exterior angle = 45°
Step-by-step explanation:
We know that the sum of exterior angles of a polygon is 360 degrees.
Since here we a regular polygon with eight sides (which makes it an octagon) so this means that the interior angles each would be equal to:
[tex]\frac{(n - 2) \times 180}{n} \\ \frac{(8 - 2) \times 180}{8}\\ \frac{6 \times 180}{8} \\ \frac{1080}{8} [/tex] = 135 degrees
We know that each interior angle is supplementary to the exterior angle at the vertex.
So each exterior angle = [tex]180-135[/tex] = 45 degrees

find the total area for the regular pyramid
(please follow the answer set up in the picture)
Answer:
T.A. = 144 + 36√3
Step-by-step explanation:
The pyramid has a regular triangle for a base. The other three faces are isosceles triangles.
The height of base can be found by dividing it into two right triangles. We can either use properties of a 30-60-90 triangle, or use Pythagorean theorem.
h = 6√3
So the area of the base is:
A = 1/2 bh
A = 1/2 (12)(6√3)
A = 36√3
Similarly, the height of the three isosceles triangles can be found by dividing them into two right triangles and using Pythagorean theorem.
h = √(10² - 6²)
h = 8
So the area of the isosceles triangles is:
A = 1/2 bh
A = 1/2 (12)(8)
A = 48
So the total surface area of the pyramid is:
T.A. = 3(48) + 36√3
T.A. = 144 + 36√3
