In 20 different ways 5 dessert courses can be arranged taken 2 at a time.
What are permutation and combination?A permutation is an arrangement of things where order matters, AB and BA are two different permutations.
The combination is a selection of things where order does not matter, AB and BA are the same combinations.
Given, There are 5 dessert courses in a restaurant and they will be presented two at a time in an order.
Here we have to use permutation as order matters.
Now, the permutation of 5 different things taken 2 at a time is,
= [tex]^5P_2[/tex].
= 5!/(5 - 2)!.
= 5!/3!.
= 5 × 4.
= 20 different ways.

find the area of the circle if radius is 6 and there is only 3/4 of the circled
Answer:
84.8
Step-by-step explanation:
Begin by finding the total area of the circle. You have been given the radius.
A = πr²
A = π(6)²
A = 36π
A = 113
If there is only 3/4 of the circle, then multiply the entire area by 3/4 to find the final answer.
113 x 3/4 = 84.8

What is the component form of the vector whose tail is the point (-3,2) and whose head is the point (1, -6)?
Answer:
(4, -8)
Step-by-step explanation:
The components of a vector are found by subtracting the tail from the head.
__
Head - Tail = (1, -6) -(-3, 2) = (1 -(-3), -6 -2) = (4, -8)
⇒ The component form is (4, -8), or maybe 4i -8j.

A minor-league hockey team had the following scores for the start of the season: 3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.
If the hockey team scores 9 goals in their next game, would the mean, median, or mode be more affected?
If the hockey team scores 9 goals in their next game, it means that; the mean would be the most affected.
How to find mean, median and mode?
We are given the data set as;
3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.
Let us rearrange in ascending order to get;
0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.
The mean = (0 + 1 + 1 + 2 + 2 + 3 + 3 + 4 + 4 + 5 + 5 + 6)/12 = 3
Median = (3 + 3)/2 = 3
Mode = 1, 2, 3, 3, 5
Now, if they score 9 goals in their next game, it means that;
Mean = 45/13 = 3.46
Median = 3
Mode remains the same
Thus, mean will be the most affected.

In one country, approximately 144,000 of 900,00 residences are rentals. Determine the percentage of residences in the country that are rentals
The 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We are assuming:
Total number of residence in the country = 144,000
In which 900,00 residences are rentals.
Percentage of residences in the country that are rentals:
= (90000/144000)×100
= 0.625×100
= 62.5%

A. Name the smallest angle and the largest angle of the following triangles: F 6 S 5 1. A J 5.03 7 5 G B H 5.1 2. D 4 3 E
Answer:
(smallest, largest) = (B, C), (D, E), (G, J)
Step-by-step explanation:
Side lengths of a triangle are proportional to the sine of the opposite angle. In a triangle, a larger angle will always have a larger sine. That means the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side.
__
ΔABCThe shortest side is 5 units, opposite angle B. The longest side is 7 units, opposite angle C.
smallest angle: Blargest angle: CΔDEFThe shortest side is 3 units, opposite angle D. The longest side is 5 units, opposite angle E.
smallest angle: Dlargest angle: EΔGHJThe shortest side is 5 units, opposite angle G. The longest side is 5.1 units, opposite angle J.
smallest angle: Glargest angle: J_____
Additional comment
Angles in a triangle may exceed 90°. The sine function actually is decreasing for angles above 90°. However, since the total of angles of a triangle must be exactly 180°, there cannot be two angles in a triangle such that the smaller angle has the larger sine.

Write a linear equation in point-slope form for the line that goes through (-1,3) and (1, -9).
A. y- 3 = -6(x+1)
B. y+1=-6(x-3)
C. y-3= 6(x+1)
D. y + 1 = 2(x-3)
The correct answer is A. y - 3 = -6(x + 1) of the linear equation in point-slope form for the line that goes through (-1,3) and (1, -9).
To write the linear equation in point-slope form, we need to use the formula:
[tex]y - y_1 = m(x - x_1),[/tex]
where [tex](x_1, y_1)[/tex] represents one of the given points, and m represents the slope of the line.
Step 1: Find the slope (m):
[tex]m = \frac {(y_2 - y_1) }{(x_2 - x_1)}\\= \frac {(-9 - 3)} { (1 - (-1))}\=\frac {-12 } {2}= -6.[/tex]
Step 2: Choose one of the given points (-1, 3), and substitute its coordinates into the point-slope form:
[tex]y - 3 = -6(x - (-1)).[/tex]
Step 3: Simplify and rearrange the equation:
[tex]y - 3 = -6(x + 1)\\y - 3 = -6x - 6.[/tex]
Therefore, the correct equation is A. y - 3 = -6(x + 1).

Tom bought a computer for 15% off from the list price of p dollars. if the sales tax was 8%, how much did he pay for the computer including sales tax?
The amount paid for the computer including sales tax is 0.918p
How to determine the amount paid?The price paid is given as:
Price = p
A 15% off means that he pays 85%.
So, we have:
Amount = 85% * p = 0.85p
A sales tax of 8% means:
Total = 0.85p * (1 + 8%)
Evaluate the product
Total = 0.918p
Hence, the amount paid is 0.918p

Answer:
[tex]x = - \frac{7}{4} \: \frac{1}{2} [/tex]
Step-by-step explanation:
[tex]8 {x}^{2} + 14x - 4x - 7 = 0 \\ 2x(4x + 7) - (4x + 7) = 0 \\ (4x + 7)(2x - 1) = 0[/tex]
Answer:
[tex]\large \text{$x_1$}=-\dfrac{7}{4}, \large \text{$x_2$}=\dfrac{1}{2}[/tex]
Step-by-step explanation:
Given: 8x² + 10x - 7 = 0
When factoring trinomials of the form ax² + bx + c:
multiply the leading coefficient and the last term.find the product factors that add to give you the coefficient of the middle term.rewrite the polynomial with those factors replacing the middle term.1. Split the middle term:
⇒ 8 × -7 = -56 [multiply the leading coefficient and the last term]
⇒ 14, -4 [find the product factors that add to the middle term's coefficient]
⇒ 8x² + 14x - 4x - 7 = 0 [rewrite with those factors replacing the middle term.]
2. Factor by grouping:
⇒ 8x² + 14x - 4x - 7 = 0 [factor out 2x]
⇒ 2x(4x + 7) - 4x - 7 = 0 [factor out -1 or the negative sign]
⇒ 2x(4x + 7) -1(4x + 7) = 0 [factor out 4x + 7]
⟹ (4x + 7)(2x - 1) = 0
3. Separate into 2 cases:
4x + 7 = 02x - 1 = 0
Case 1:
⇒ 4x + 7 = 0 [subtract 7 from both sides]
⇒ 4x + 7 - 7 = 0 - 7
⇒ 4x = -7 [divide both sides by 4]
⇒ 4x ÷ 4 = -7 ÷ 4
⟹ x = [tex]\bold{-\dfrac{7}{4}}[/tex]
Case 2:
⇒ 2x - 1 = 0 [subtract 1 from both sides]
⇒ 2x - 1 + 1 = 0 + 1
⇒ 2x = 1 [divide both sides by 2]
⇒ 2x ÷ 2 = 1 ÷ 2
⟹ x = [tex]\bold{\dfrac{1}{2}}[/tex]
