How many different ways can three people from leni isko ping leody manny selected to attend a meeting
The selection of the three people is an illustration of combination
The number of different ways the three people can be selected is 10
How to determine the number of selection?From the question, we have the following parameters:
Number of people, n = 5Number of people to select, r = 3The number of different selections is then calculated using the following combination formula
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
So, we have:
[tex]^5C_3 = \frac{5!}{(5 - 3)!3!}[/tex]
Evaluate the difference
[tex]^5C_3 = \frac{5!}{2! * 3!}[/tex]
Evaluate the quotient
[tex]^5C_3 = 10[/tex]

What is income tax?Income tax is a tax applied on individuals or entities concerning income or profit earned by them.
The categories are 6.2% as social security tax 1.45% as Medicare tax 0.9% as Medicare surtax for employees earning more than $200,000
Medicare Tax
6.2% x 165000
= 10230
Social Security Tax
= 1.45% x 165000
= 2392.5
Since 10230+2392.5 = 12622.50
Social security is taxed at 6.5 percent and medicare is taxed at 1.45 percent. it will always be that number unless the government changes it.
The categories are 6.2% as social security tax 1.45% as Medicare tax 0.9% as Medicare surtax for employees earning more than $200,000
As the income of the employee is less than $200000, so there will be no medical surtax.

The following table contains the first 5 terms of an infinite arithmetic sequence. What is the 7th term?
f(n) is an arithmetic sequence, so the difference between any two consecutive terms is the same. For instance,
f(2) - f(1) = -0.6 - 0.7 = -1.3
so for all natural numbers n, we should have
f(n) - f(n - 1) = -1.3
Then
f(6) - f(5) = -1.3 ⇒ f(6) = -4.5 - 1.3 = -5.8
f(7) - f(6) = -1.3 ⇒ f(7) = -5.8 - 1.3 = -7.1

Give the appropriate theorem or postulate that can
be used to prove the triangles similar:
A. AA Postulate
B. ASA Postulate
C. SSS Postulate
D. SAS Postulate
Answer:
Step-by-step explanation:
<ACB = <ECD
These 2 angles are vertically opposite and are equal.
<B = <D
They are both right angles are therefore equal.
The answer is the AA postulate.
A
Note
ASA is a congruence postualate. If S is between two angles that can be shown to be corresponding and equal, then you will have 2 congruent triangles.
SSS if three sides of 1 triangle = 3 sides of a second triangle, then the 2 triangles are congruent. If the the three sides of one triangle are in a ratio with 3 sides of the other triangle, then the triangles could be similar, but that is not the case here.
SAS this is the terminology for congruence as well. We don't know enough to use it for similarity. Some sort of ratio would have to be mentioned to do that.
You are intended to use AA as your answer.

Find the interest on the following loan.
$5315 at 5%; loan made on August 10 and due December 23
The interest amount (simple interest ) on the loan amount $5315 at 5% from 10th aug to 23rd dec. of same year is $105.50
How to calculate simple interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
For this case, we're specified that:
Principal amount = $5315Rate of interest = R% = 5% (assumingly annually, and simple interest).Time for which interest was applied: 10th aug to 23rd dec.( of same year assumingly)Converting this time in terms of year, we get:
Aug has 31 days, Sept has 30 days, Oct. has 31 days, Nov has 30 days.
From 10th aug, till its last, there went 22 days.
Whole sept and oct and nov. was spent (30+31+30 = 91 days)
And then there were 22 days of december(23rd day not covered assumingly)
So, total days = 22+22+91 = 145 days.
Assuming averagely 365.25 days in an year, we get the average time for which the interest will be calculated as:
[tex]\dfrac{145}{365.25} \approx 0.397 \: \rm years[/tex]
Thus, we get: the amount of interest as:
[tex]I = \dfrac{P \times R \times T}{100}\\\\I \approx \dfrac{5315 \times 5\times 0.397}{100} \approx 105.50 \: \rm dollars[/tex]
Thus, the interest amount (simple interest ) on the loan amount $5315 at 5% from 10th aug to 23rd dec. of same year is $105.50

Alexander sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
8 visitors purchased no costume.
340 visitors purchased exactly one costume.
28 visitors purchased more than one costume.
If next week, he is expecting 600 visitors, about how many would you expect to buy more than one costume? Round your answer to the nearest whole number.
Answer:
45 people
Step-by-step explanation:
1) Add all of the origanal visitors (376)
2) Find the ratio (28/376) = 0.0744
3) Either 28/376 * 600 OR 0.0744 * 600 (I would recomend the fraction for more accurate answers, but because it says to round to the nearest whole number either will work, but you should still use fraction)
4) 44.6908
5) Round to 45 people
Answer:
600 visitors expected. Add 28 visitors for buying more than one costume and you get 628 visitors. I think you are complicating it.

This is a practical exercise. However, the following definitions and equations will help you to arrive at the density of the objects you will put on the tray.
What is density?Population density is defined as the number of people (in this case) items (N)/area of space that they occupy. (A)
Note that the area to be occupied by the items you will put on the Square Tray is 10 X 10 = 100inches.

The perimeter of a triangular window is 141 inches. The ratio of the side lengths of the window is 11:18:18. What are the side lengths of the window?
The perimeter of a triangular window is the sum of its side lengths
The side lengths of the window are 33 inches, and 54 inches
How to determine the side lengths?The ratio is given as:
Ratio = 11: 18 : 18
Rewrite as:
Ratio = 11x: 18x : 18x
Express as sum
Sum = 11x + 18x + 18x
Sum = 47x
The perimeter is 141 inches.
So, we have:
47x = 141
Divide both sides by 47
x = 3
Recall that:
Ratio = 11x: 18x : 18x
So, we have:
Ratio = 11*3: 18*3 : 18* 3
Ratio = 33: 54 : 54
Hence, the side lengths of the window are 33 inches, and 54 inches
