What is binomial theorem?

An expression that has been raised to any finite power can be expanded using the binomial theorem. A useful expansion technique with applications in probability, probability theory, and algebra is the binomial theorem.

The given expression is,

(n + 3)⁶.

To find the fifth term in the expression,

Use binomial expansion method,

[tex](x+y)^n = ^{n}C_0 x^nny^0 + ^nC_1 x^{n-1}y^1 + ^nC_2 x^{n-2} y^2 + ...[/tex]

Use the binomial formula for expression (n + 3)⁶,

If the cost of 4 1/2litres of milk is 89 1/2rupees, find the cost of 1 litre of milk. Pls explain too

Answers

Answer:

x=19.88

Step-by-step explanation:

Okay, let's try and create a "table" of what we know, and what we are looking for.

4.5 litres of milk            cost                 89.5 rupees

1 litre                              costs                x rupees

Obviously, we are looking for x.

The method I'm about to tell you, might be familiar. Imagine that there was a giant X where the words cost and costs are above. There'd be a line connecting 4.5 litres of milk with the rupees we are looking for, and another line connecting 1 litre with the 89.5 rupees.

If we were to form an equation to solve for x, we'd put the connecting terms together, with an "=" between them, so we'd have this:

4.5*x=1*89.5

That's our equation, so let's solve for x.

x=89.5/4.5 => x=19.88 , let's say 20 rupees

Step-by-step explanation:

one square would simply be base x height our base is 5 and height is 5 so i multiply that and get 25 since this is a cube all sides are equal so I will simply just multiply 25 by the number of sides since a cube has 6 sides our equation to get the answer would be 25 x 6 = 150 so 150 is our answer!

You flip a coin 50 times. Of the 50 flips, the coin landed on heads 30 times. Use the questions below to compare the experimental probability of flipping heads with the theoretical probability of flipping heads.

Answers

Given:

Of the 50 flips, the coin landed on heads 30 times.

To find:

The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.

Solution:

We have,

Total number of trials = 50

Total number of heads = 30

The experimental probability of flipping heads is:

[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]

[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]

[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]

[tex]\text{Experimental probability}=0.6[/tex]

A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:

[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]

[tex]\text{Theoretical probability}=0.5[/tex]

Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.

Answers

Answer:

The total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

Step-by-step explanation:

Complete question

Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.

Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.

Write an equation to represent the number of stamps in Tom’s collection based on the  number of weeks he has been collecting stamps.

Solution

Let "X" be the number of weeks for which Tom collected the stamps

The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]

It is given that he collects 8 stamps per week

So the total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

What is the volume of the trapezoidal prism with a height of 10 cm, base lengths of 3 and 4 cm, base height of 2 cm?

Answers

Given:

Height of a trapezoidal prism = 10 cm

Base lengths are 3 and 4 cm.

Base height = 2 cm

To find:

The volume of the trapezoidal prism.

Solution:

Base area of a trapezoidal prism

[tex]B=\dfrac{a+b}{2}\times h[/tex]

Where, a,b are base lengths and h is the base height.

Putting [tex]a=3,b=4,h=2[/tex], we get

[tex]B=\dfrac{3+4}{2}\times 2[/tex]

[tex]B=7[/tex]

The volume of a trapezoidal prism is:

[tex]V=Bh[/tex]

Where, B is the base area and h is the height of the prism.

Putting [tex]B=7,h=10[/tex], we get

[tex]V=7\times 10[/tex]

[tex]V=70[/tex]

Therefore, the volume of the trapezoidal prism is 70 cubic cm.

2. Mercury High School is requiring students to purchase parking permits this year in order to

use campus parking lots. It costs the school a one-time fee of $500 to have the logo

designed. It also costs $2 per permit to print and cut out each one. They expect the average

cost of each permit to be $6.

a. Write a rational equation that describes the situation above.

b. How many parking permits does Mercury High School need to sell in order for the

average cost of a student's parking permit to be $6? Solve your equation from part (a)

to answer the question. Justify your solution as it relates to the context.

Answers

Answer:

a. $6 =  ($500 + $2q) / q

b. 125

Average cost =  ($500 + $2q) / q

($500 + $2x 125) / 125 = $6

Step-by-step explanation:

Average cost = total cost / quantity produced

total cost = fixed cost + variable cost

Fixed costs are costs that do not vary with output. e.g. the cost of the logo

Variable costs are costs that vary with production e.g. cost of printing and cutting

Variable cost = $2 x quantity of parking ticket sold

let q =  quantity of parking ticket sold

variable cost = 2q

$6 = ($500 + $2q) / q

to determine the number of parking ticket to be sold for average cost to be $6, take the following steps

Multiply both sides of the equation by q

6q = 500 + 2q

collect like terms

6q - 2q = 500

4q = 500

q = 125

125 tickets have to be sold for average cost to the $125

to justify the answer, replace 125 in the first equation to confirm if $6 would gotten as the average cost

($500 + $2q) / q

($500 + $2x 125) / 125 = $6
