Median = [tex]\frac{4. 25 + 4. 75}{2}[/tex]

Median = $ 4. 5

Mode is the number with the highest repeats.

From the given data, none of the numbers was repeated.

Thus, there is no mode.

MAD, mean absolute deviation = |data value - mean|

MAD = [tex]|(3. 50 - 4. 72) + (4. 25 - 4. 72) + (6 - 4. 72) + (4. 75 - 4. 72) + (5. 80 - 4.72) + (4- 4. 72) |[/tex]

MAD = [tex]1. 22 + 0. 47 + 1. 28 + 0. 03 + 1. 08 + 0. 72[/tex]

MAD = $ 4. 8

IQR, interquartile range = Quartile 3 - quartile 1

IQR = 4. 75 - 4. 25

IQR = $0. 5

Note that  the mean and median are the most common measures of center.

A measure of variability is a single number that is  used to describe the spread of a data set

The measure of the center best for the data is the median = $4. 5

Answer:

factoring

Step-by-step explanation:

The measurement of the angle is 15° (if initial angle is 0°).

Turning Through One-degree Angles

An angle is said to have an angle measure of n degrees if it rotates across n one-degree angles. Since turning through one degree means making an angle of one degree, every time you take a turn of one degree, you rotate through one degree more. Thus, turning through n one-degree angles give rise to an angle of n degrees.

Measurement of the Angle

It is given that the angle has turned through 15 one-degree angles. Thus, the angle will turn through 15°.

Let us assume the initial angle to be x°.

Then, the new angle after 15 one-degree turns would be (x+15)°

If initial angle, x = 0°, the measurement of the angle formed is 15°.

The factorized form of the given function, f(x) = 2x⁴ - x³ - 18x² + 9x, is, f(x) = x(2x - 1)(x + 3)(x - 3), and the complete statement is, From left to right, function f has zeros at x = -3, x = 0, x = 1/2, and x = 3.

In the question, we are asked to find the factors of the function f, and complete the given statement.

The function f, given to us is:

f(x) = 2x⁴ - x³ - 18x² + 9x.

To factor the function, we first group the terms as follows:

f(x) = (2x⁴ - 18x²) - (x³ - 9x).

Now, we take common terms out of the group as follows:

f(x) = 2x²(x² - 9) - x(x² - 9).

Now, we again take common terms, as follows:

f(x) = (2x² - x)(x² - 9),

or, f(x) = x(2x - 1)(x + 3)(x - 3).

This is the factored form of the given function, f.

The statement given to us is:

From left to right, function f has zeros at x = _, x = _, x = _, and x = _.

To find the zeroes of the function, we equate the factorized form to 0.

x(2x - 1)(x + 3)(x - 3) = 0.

By zero-product rule, the zeroes are at:

x = 0,

2x - 1 = 0, or, x = 1/2,

x + 3 = 0, or, x = -3,

x - 3 = , or, x = 3.

Arranging these in ascending order, the zeroes are at: -3, 0, 1/2, and 3.

Thus, the factorized form of the given function, f(x) = 2x⁴ - x³ - 18x² + 9x, is, f(x) = x(2x - 1)(x + 3)(x - 3), and the complete statement is, From left to right, function f has zeros at x = -3, x = 0, x = 1/2, and x = 3.

Step-by-step explanation:

in a number like 125,734,016

the right most position has the weight 10⁰ = 1

so, 6×1 = 6.

the second right most position has the weight 10¹ = 10.

so, 1×10 = 10

the third right most position has the weight 10² = 100.

so, 0×100 = 0

the 4th right most position has the weight 10³ = 1000.

so, 4×1000 = 4,000

the 5th right most position has the weight 10⁴ = 10000.

so, 3×10000 = 30,000

the 6th right most position has the weight 10⁵ = 100000.

so, 7×100000 = 700,000

the 7th right most position has the weight 10⁶ = 1000000.

so, 5×1000000 = 5,000,000

the 8th right most position has the weight 10⁷ = 10000000

so, 2×10000000 = 20,000,000

Answer:

Option D

Step-by-step explanation:

The triangle ABJ is equitorial

So area

Then mBJ is a arc which is 1/6th of circle

Area.

So area of unshaded region

Answer:

[tex]\textsf{d.} \quad r^2\left(\dfrac{\pi}{6}- \dfrac{\sqrt{3}}{4}\right)[/tex]

Step-by-step explanation:

To find the area of the unshaded region, subtract the area of ΔJGB from the area of sector JGB.

The measure of an arc is equal to its corresponding central angle measure.  Therefore, the central angle of sector JGB is 60°.

As the two sides of ΔJGB adjacent the central angle are the radii of the circle (and therefore equal in length), ∠GJB = ∠GBJ.  

Interior angles of a triangle sum to 180°.  Therefore, all interior angles of ΔJGB are 60° which makes it an equilateral triangle.

Area of an equilateral triangle:

[tex]\sf A=\dfrac{\sqrt{3}}{4}a^2 \quad \textsf{(where a is the side length)}[/tex]

As the side length of the given equilateral triangle is the radius (r):

[tex]\implies \sf Area\:of\:triangle=\dfrac{\sqrt{3}}{4}r^2[/tex]

To find the area of the sector, first convert degrees to radians by multiplying the degrees by π/180 :

[tex]\implies 60^{\circ}=60 \times \dfrac{ \pi}{180}=\dfrac{\pi}{3}\:\:\sf radians[/tex]

Area of a sector of a circle

[tex]\textsf{A}=\dfrac12 r^2 \theta \quad \textsf{(where r is the radius and the angle }\theta \textsf{ is in radians)}[/tex]

Substituting the angle in radians, the area of the sector is:

[tex]\implies \sf A=\dfrac{1}{2}r^2\left(\dfrac{\pi}{3}\right)[/tex]

[tex]\implies \sf A=\dfrac{\pi}6}r^2[/tex]

Area of the unshaded region:

[tex]\begin{aligned}\textsf{Area of unshaded region} & =\textsf{Area of sector} - \textsf{Area of triangle}\\\\& = \dfrac{\pi}{6}r^2 - \dfrac{\sqrt{3}}{4}r^2\\\\& = r^2\left(\dfrac{\pi}{6}- \dfrac{\sqrt{3}}{4}\right)\end{aligned}[/tex]

Therefore, the solution is option D.

The equation of the circle with a center (-5, -6) and a radius of 5 is (x + 5)² + (y + 6)² = 25.

Given the following:

Center (-5, -6) = (h, k)

Answer:

[tex]x^2+(y-3)^2=36\\[/tex] and [tex]x^2+(y+8)^2=36[/tex]

Step-by-step explanation:

So the general formula for a circle is usually represented as: [tex](x-h)^2+(y-k)^2=r^2[/tex] where (h, k) is the center of the circle and r is the radius of the circle.

Since the diameter is 12, the radius is going to be 6, because the radius is half the diameter. We now square that value (since it's squared in the equation), you get 36, which is going to be on the right side.

The last thing to know is since it's on the y-axis, that means h=0, since if h didn't equal 1, it would either be to the right or left of the y-axis. So the equation should look something like this: [tex]x^2+(y-k)^2=36[/tex] where k can be any real number.

So this gives you the two equations:
[tex]x^2+(y-3)^2=36\\[/tex] and [tex]x^2+(y+8)^2=36[/tex]

The statement that is true about the domain and range of each function is; A) Both the domain and range of the transformed function are the same as those of the parent function.

We are told that the graph of f(x) = |x| is reflected across the y-axis. Thus;

|-x| = x

Now, the function is translated to the left by 5 units and so the transformed function is; g(x) = |x + 5|

Thus, from the graph, we get;

Domain of both functions is the set of all real numbers.

Range of both functions is the set {y|y ≥ 0}

Thus, we conclude that Both the domain and range of the transformed function are the same as those of the parent function.
