What is the permutation and combination?

Permutation and Combination form the principles of counting and they are applied in various situations.

A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.

Here given that,

A blood bank needs [tex]5[/tex] people to help with a blood drive. [tex]18[/tex] people have volunteered.

So,

[tex]^nC_r=\frac{n!}{r(n-r)!}[/tex]

Here [tex]n=18, r=5[/tex]

Then

[tex]^{18}C_5=\frac{18!}{5(18-5)!}\\\\^{18}C_5=\frac{18!}{5(13)!}\\\\^{18}C_5=\frac{(18)(17)(16)(15)(14)(13)}{5(13)}\\\\^{18}C_5=\frac{(18)(17)(16)(15)(14)}{5}\\\\^{18}C_5={(18)(17)(16)(3)(14)}\\\\^{18}C_5=205632[/tex]

Hence, the different groups of [tex]5[/tex] can be formed from the [tex]18[/tex] volunteers is

[tex]^{18}C_5=205632[/tex].

Step-by-step explanation:

Answer:

< S = 32

Step-by-step explanation:

< S = 180 - (< R + < T)

< R = < T

15x - 31 = 9x + 11

6x = 42

x = 7

< R = 74

< S = 180 - (74 + 74)

< S = 180 - 148

< S = 32

Answer:

1 Milk = 1.5 Chocolate syrup

Step-by-step explanation:

3 ÷ 2 = 1.5

12 ÷ 8 = 1.5

3/2 ÷ 1 = 1.5

15 ÷ 10 = 1.5

3/4 = 0.75

0.75 * 200 = 150

The simplified form of the given expression is 150.

Given that, 3/4 ×200.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Here, 3/7 =0.75

So, 0.75 ×200

= 150

Hence, the simplified form of the given expression is 150.

Answer:

D

Step-by-step explanation:

5 + x = 3(x - 7) + 6

~Distribute right sides

5 + x = 3x - 21 + 6

~Combine like terms

5 + x = 3x - 15

~Subtract 5 to both sides

x = 3x - 20

~Subtract 3x to both sides

-2x = -20

~Divide -2 to both sides

x = 10

Step-by-step explanation:

on Edge

In the given triangle ABC, point D is orthocenter when BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.

"The orthocenter is the point where all the three altitudes of the triangle cut or intersect each other."

In the given triangle ABC, to be an orthocenter, all three lines that are drawn from the points A, B, and C are must be perpendicular to the opposite side of the triangle.

Therefore,  AG must be perpendicular to BC, BE must be perpendicular to AC, and CF must be perpendicular to AB.

Step-by-step explanation:

A cube has 6 sides. 1, 2, 3, 4, 5, 6.

2, 3, and 5 are primes.

3/6=1/2.

Answer:

This equation is in standard form, so to make graphing easier you need to put it in y=mx+b form or slope, intercept form.

Step-by-step explanation:

I have attached a photo of what the graph would look like.

However, in the future you should know how to turn this into a slope intercept equation.

-2x+7y=-21

+2x        +2x

7y=2x-21

divide the entire equation by 7

y= 2/7x-3

That is a full equation in slope intercept form.

Hopefully this helps!

The graph of the linear equation -2x + 7y = -21 is a line passing through the points (0, -3) and (10.5, 0) which is given below.

Given a linear equation:

-2x + 7y = -21

It is required to graph the linear equation.

In order to graph this, first, it is required to find the points through which it passes.

Substitute x = 0.

7y = -21

y = -3

So, the line passes through (0, -3), which is the point where the line touches the y-axis.

Substitute y = 0.

-2x = -21

x = 10.5

So, the line passes through (10.5, 0), which is the point where the line touches the x-axis.

Draw a line passing through these points. This is the graph.

Hence, the line passes through the points (0, -3) and (10.5, 0).

Step-by-step explanation:

Answer:

x = 15/2

Step-by-step explanation:

the smaller triangle missing side by using pythagorean theorem

a^2 + b^2 = c^2

4^2 + b^2 = 5^2

b^2 = 25-16=9

b=3 the missing leg for the small triangle;

now use proportionality by saying [tex]\frac{4}{6}[/tex] = [tex]\frac{3}{y}[/tex]; where y is the one leg in the larger triangle

y = 6*3/4 = 9/2

use pythogorean theorem again

a^2 + b^2 = x^2

6^2 + (9/2)^2 = x^2

36 + 81/4 = x^2

144/4 + 81/4 = x^2

225/4 = x^2

The dog food will last 28 days

*you just have to divide 35 into 1 1/4*

A bag of 35 pounds of dog food last would last Amar 28 days.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Amar's dog eats 1 1/4 = 5/4 pounds of dry dog food every day.

Now, To determine the number of days a bag of 35 pounds last we should divide the total amount of food by the amount eaten each day which is,

= (35/(5/4) days.

= 35×(4/5) days.

= 28 days.
