Answer:
92.5
Step-by-step explanation:
First, we need to put the data in order from smallest to largest:
$71, 81, 89, 92, 93, 94, 94, 99$
There are 8 numbers in the data set, which is an even number. To find the median, we need to average the two middle numbers.
The middle two numbers are 92 and 93, so the median is:
$(92+93)/2 = 92.5$
Therefore, the median of the data is 92.5.

Step-by-step explanation:
A full revolution on a circle/radians is 2[tex]\pi[/tex], so keep adding or subtracting 2[tex]\pi[/tex] til you get a base angle, that's when the sign changes. Then decide which quadrant your in.
For this one the equivalent of 2[tex]\pi[/tex] is [tex]6\pi /3[/tex]
-29[tex]\pi[/tex]/3 + [tex]6\pi /3[/tex]
= -23[tex]\pi[/tex]/3 + [tex]6\pi /3[/tex]
= -17[tex]\pi[/tex]/3 + [tex]6\pi /3[/tex]
= -11[tex]\pi[/tex]/3 + [tex]6\pi /3[/tex]
= -5[tex]\pi[/tex]/3 + [tex]6\pi /3[/tex]
= 1[tex]\pi[/tex]/3 sign changed it's equavalent to [tex]\pi /3[/tex] Which is in the first quadrant. See unit circle.
-5[tex]\pi[/tex]/6 + [tex]12\pi /6[/tex]
=[tex]7\pi /6[/tex] third quadrant, i count quadrants by know [tex]\pi[/tex]/6 is 30°, so every 30° line is 1/6 of the unit circle. when i count 7 of them that's in the 3rd quadrant. Don't forget to count the axis's
2[tex]\pi[/tex]/3 is in the 2nd quadrant. Count my pi/3's which is 60°
45[tex]\pi[/tex]/7 - 14[tex]\pi[/tex]/7
= 31[tex]\pi[/tex]/7 - 14[tex]\pi[/tex]/7
=17[tex]\pi[/tex]/7 - 14[tex]\pi[/tex]/7
=3[tex]\pi[/tex]/7 - 14[tex]\pi[/tex]/7
= -11[tex]\pi[/tex]/7 1/7th's is not your typical unit circle angle
This one i think of logically. this is -1 4pi/7
1 pi going backwards is 180
keep going backards 4/7 is bigger than 1/2 so it's in the 1st quadrant
A teacher gives 6 students some cards to play a game
If teacher has total "52 cards", and teacher gives each student "1 card" until all 52 cards are distributed, then number of students which got exactly 9 cards are (b) 4 students.
There are 6 students and 52 cards. The teacher gives each student one card until all 52 cards are given out in game. We want to know how many students receive exactly 9 cards.
To solve the problem, we divide the total number of cards (52) by the number of students (6) to find the average number of cards per student.
⇒ 52 cards / 6 students = 8.67 cards per student;
Since we can't give a student a fraction of a card, we need to round down to 8 cards,
If we give each student 8 cards, that will total of 8 cards × 6 students = 48 cards. which leaves 4 cards left over that we can't give out evenly.
This means that four-students will receive 9 cards each and two students will receive 8 cards each.
Therefore, the correct option is (b).

The length of m∠WYX is equal to 12π units.
How to calculate the area of a sector?In Mathematics and Geometry, the area of a sector can be calculated by using the following formula:
Area of sector = θπr²/360
Where:
r represents the radius of a circle.θ represents the central angle.By substituting the given parameters into the area of a sector formula, we have the following;
Area of sector = θπr²/360
16π = θ(π/360) × 8²
Central angle, θ = 0.5π
m∠WYX = 2π - m∠WX
m∠WYX = 2π - 0.5π
m∠WYX = 1.5π
Length of m∠WYX = (1.5π)/2π × 2πr
Length of m∠WYX = (1.5π)/2π × 2π(8)

The quadratic polynomial with integer as coefficients that has four real roots including these conjugates is a² + b² - 2ab - 20a - 20b + 88 ≥ 0
Here is how to derive the polynomialOne possible quartic polynomial with integer coefficients that has four real roots, including the conjugates 5+√3 and 5-√3, is:
(x - 5 - √3)(x - 5 + √3)(x - a)(x - b)
where a and b are the remaining two roots.
Expanding the first two factors using the difference of squares formula, we get:
(x - 5)² - 3
Expanding the last two factors, we get:
x² - (a + b)x + ab
Putting it all together, the quartic polynomial is:
a² + b² - 2ab - 20a - 20b + 88 ≥ 0
To ensure that a and b are also real, we can use the fact that the discriminant of a quadratic equation ax² + bx + c = 0 with real coefficients is b² - 4ac ≥ 0. Applying this to the quadratic factor in the above polynomial, we get:
(a + b)² - 4ab ≥ 0
Expanding and simplifying, we get:
a² + b² - 2ab - 20a - 20b + 88 ≥ 0
To simplify the problem, we can set a = b, since the polynomial is symmetric with respect to the roots. Then, the inequality becomes:
2a² - 40a + 88 ≥ 0
Dividing by 2 and factoring, we get:
(a - 10)² - 12 ≥ 0
This inequality is always true for real values of a, so we can choose any real value for a and set b = a to obtain a quartic polynomial with integer coefficients that has four real roots, including the conjugates 5+√3 and 5-√3.

Answer: Option C.
The volume of a cylinder is given by the formula V = πr^2h, where r is the radius and h is the height.
Given that the diameter of the container is 24 ft, the radius (r) would be half of that, which is 12 ft.
The depth of the container (h) is given as 4 ft.
Plugging in these values into the formula, we get:
V = π(12^2)(4)
V = 3.14(144)(4)
V = 1808.6 cubic feet (rounded to the nearest tenth)
So, the storage container can hold approximately 1808.6 cubic feet of wood, rounded to the nearest tenth.

Determine the outputs if the final demand changes to 20 for X and 30 for Y.
[3]
The outputs for industries X and Y will be 31 million and 43.2 million, respectively supposedly the final demand changes to 20 for X and 30 for Y.
How do we calculate?We will start with industry X.
The final demand for X hade an increment from 14 million to 20 million with an increase of 6 million, hence the final output of X must also increase by 6 million to make up for demand.
Users Final Producers
Demand X Y
X 14 7
Y 6 18
Total 20 25
The table tells us that for every additional million of final demand for X, the producers in industry X need to produce 0.5 million of output.
So the new total output for industry X is 28 + 3 = 31 million.
For industry Y
The same scenario occurred for Industry Y which had final output of 12 in order to meet the demand increment.
So the new total output for industry Y is 36 + 7.2 = 43.2 million.
In conclusion, the outputs for industries X and Y will be 31 million and 43.2 million, respectively, if the final demand changes to 20 for X and 30 for Y.

Let f(t) be the sales of a gaming product, in thousands of units, after t months.
The sales after 5 months is 36,000 units (since f(t) is given in thousands of units).
The given function f(t) represents the sales of a gaming product in thousands of units after t months. To find the sales after 5 months, we need to substitute t = 5 in the function f(t) and evaluate the expression. f(5) = 5(5) + 11

As per the unitary method, each piece is 3.25 meters long by dividing the total length of the ribbon by the number of pieces.
Larry has cut a ribbon into 8 equal pieces. The total length of the ribbon is 26 m. We need to find out the length of each piece of the ribbon.
To do this, we can use the unitary method. We know that the ribbon is divided into 8 equal pieces, so each piece is 1/8th of the total length of the ribbon.
Therefore, we can find the length of each piece by dividing the total length of the ribbon by 8:
Length of each piece = Total length of ribbon / Number of pieces
Length of each piece = 26 m / 8
Length of each piece = 3.25 m
So, each piece of the ribbon is 3.25 meters long.

What is the domain of the function?Here we want to find the domain of the function:
