The way we can write the expression (a - b)⁵ without simplifying is by using Pascals' Triangle to get; a⁵ + 5a⁴b + 10a³b² + 10a²b³ + 5ab⁴ + b⁵

Pascal’s Triangle is a method that is used to know the binomial coefficients of terms of binomial expression (x + y)ⁿ, where n can be any positive integer and x,y are real numbers.

For the expression (x + y)⁵, the coefficients are;

1, 5, 10, 10, 5, 1

According to the binomial expansion, the power of m will be decreasing while the power of 5 will be increasing as shown below. Thus;

(a - b)⁵ = (a + (-b))⁵ = a⁵ + 5a⁴b + 10a³b² + 10a²b³ + 5ab⁴ + b⁵

The filed has a perimeter value of 720000 decimeters

From the question, the area of the field is given as

Area = 3.24 hectares

Also, we have the shape of the field to be square

So, we start by calculating the side length of the field using

Length = √Area

Substitute the known values in the above equation

Length= √3.24 hectares

Length= √3.24 * 10000 square meters

Evaluate the square root

Length= 18000 meters

The perimeter is calculated as

P = 4 * Length

So, we have

P = 4 * 18000 meters

Evaluate

P = 72000 meters

Convert

P = 720000 decimeters

Hence, the perimeter is 720000 decimeters

Note the in such type of questions the term 'probability' and 'proportion' can be used in place of each other. It is because the probability gives the proportion of favorable outcomes to the total outcomes.

Let X be the random variable representing the number of data points greater than or equal to 22.

Given that the mean and standard deviation is 18.5 and 3.25, respectively.

Consider the formula for z-score as,

So the probability is calculated as,

From the Standard Normal Distribution Table,

Substitute this value,

Thus, there is 0.1401 or 14.01% probability that a data will be greater than or equal to 22.

So, the 14.01% of the data is expected to be 22 or greater.

D: [tex]1\leq x\leq 3[/tex].

R: [tex]0\leq y\leq 4[/tex]

8b)

D: [tex]x\geq 0[/tex]

R: [tex]y\geq 1[/tex]

Step-by-step explanation:

8a) The domain is the set of all possible numbers the x values could be. If there is no corresponding y value for an x value, that x value would not be considered part of the domain.

In the question, the function starts at x = 1 and continues until 3. The ends of the function are closed, so it is inclusive. This can be written as [tex]1\leq x\leq 3[/tex].

The range is all the possible y values. The function does not go below y = 0 and has a maximum of 4. The ends of the function are closed, so it is inclusive. This can be written as [tex]0\leq y\leq 4[/tex]

8b) We can do the same for this problem. The x has a minimum at 0 and continues to go on without an upper bound(as indicated by the arrow), is also includes the point where x=0. Therefore, the domain can be written as [tex]x\geq 0[/tex].

As for the range, the y minimum is 1 and the function continues to increase as shown by the upwards slope and arrow. The function also includes the point where y=1, so it can written as [tex]y\geq 1[/tex]

Answer:

4/7

Step-by-step explanation:

6/7 of 2/3

= 6/7 * 2/3

= 12/21

= 4/7

The sign of 3.456+(-3.456) is neither positive nor negative—the sum is zero.

We are asked to find the sign of 3.456+(-3.456)

This expression can be simply written as 3.456 - 3.456 because of the identity we have, x+(-y) = x-y

Now if same quantities are subtracted, we get zero only.

Also zero is neither positive nor negative.

Hence there is no sign for 3.456+(-3.456).

Also 3.456+(-3.456) = 0.

The value of x is 4.8cm.

Here BD // EF and BF // DE

So from this, we have ∠ABF = ∠EFC

Let's take two triangles ΔABC and ΔFCE

∠C =∠C (common angle)

∠ABC = ∠EFC

So ΔABC ≅ ΔEFC

So ∠BAC = ∠FEC

AB/ EF = BC/ FC

AB = 8cm, EF =x, BC = 12cm, FC= 12-x

8/x = 12/ 12-x

2/x = 3/ 12-x

Answer: y = (5x/4) + 2

Step-by-step explanation:

Answer:

y = 5/4x + 2

Step-by-step explanation:

First, we convert 4x + 5y = 15 to slope intercept form (y=mx+b):

5y = -4x + 15

Divide both sides by five

y = -4/5 (x) + 3

The slope is -4/5

A perpendicular slope is the negative reciprocal of the other line. To find the negative reciprocal, you switch the numerator and denominator and switch the sign.

Slope = 5/4

Plug the slope and (-4, -3) into the slope-intercept form:

-3 = ( 5/4 · -4 ) + b

Isolate b (the y-intercept):

-3 = -5 + b

b = 2

y = 5/4x + 2

If about 5% of americans have blue eyes, the probability of 3 people selected at random having blue eyes is 1/8000.

About 5% of americans have blue eyes

The probability of a person having blue eyes = 5% = 5/100

Eyes colour of a person is an indepedent event, which means the eye colour of one individual is independent of the other. The probability of one individual having blue eyes or not is independent of another person.

In case of independent event the probability of A intersection B = probability of A multiplied with probability of B

P(A∩B) = P(A) x P(B)

P(A∩B∩C) = P(A) x P(B) x P(C)

The probability that all 3 have blue eyes = 5/100 x 5/100 x 5/100

= 125/1000000

= 1/8000

Therefore, if about 5% of americans have blue eyes, the probability of 3 people selected at random having blue eyes is 1/8000.

Depending on the context, the phrase "linear model" is used differently in statistics.

From the linear model we can see that the water balloon is thrown from a height of 40 feet upwards.

Now the balloon reaches a height of 70 feet and then falls back down on earth due to gravity.

Answer:

A) [tex]y = \frac{1}{10}x + 28[/tex]

B) $116.5

Step-by-step explanation:

The data we are given is:

• for 440 minutes of usage, the total cost is $72

• for 940 minutes of usage, the total cost is $122

A)

In order to find an equation in the form [tex]y = mx + b[/tex], we must first express the given data as coordinates in the form [tex](x, y)[/tex].

We are told that [tex]x[/tex] is the number of monthly minutes, and [tex]y[/tex] is the total monthly fee. Therefore the first piece of data expressed as coordinates is (440, 72), and for the second piece of data, it is (940, 122).

Now that we have the coordinates, we can make an equation using the formula:

[tex]\boxed{\frac{y - y_1}{y_2 - y_1}= \frac{x - x_1}{x_2 - x_1}}[/tex],

where [tex](x_1, y_1)[/tex] is (440, 72) and [tex](x_2, y_2)[/tex] is (940, 122).

Substituting the values into the formula, we get:

[tex]\frac{y - 72}{122 - 72}= \frac{x - 440}{940 - 440}[/tex]

⇒ [tex]\frac{y - 72}{50} = \frac{x - 440}{500}[/tex]

⇒ [tex]50 \times \frac{y - 72}{50} =50 \times \frac{x - 440}{500}[/tex]       [Multiplying both sides of the equation by 50]

⇒ [tex]y - 72 = \frac{x - 440}{10}[/tex]

⇒ [tex]10y - 720 = x - 440[/tex]    [Multiplying both sides by 10]

⇒ [tex]10y = x +280[/tex]            [Adding 720 to both sides]

⇒ [tex]y = \frac{1}{10}x + 28[/tex]    (Answer)

B)

To find the total cost if 885 minutes are used, we have to replace [tex]x[/tex] in the above equation with 885:

[tex]y = \frac{1}{10}(885) + 28[/tex]

⇒ [tex]y = 88.5 + 28[/tex]

⇒ [tex]y = 116.5[/tex]    

Therefore, the total cost will be $116.5.   (Answer)

Anton would earn $111.6 if "x" is 128 bushels.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that Anton picks corn at a local farm.

Anton is paid 80 cents per bushel for the first 50 bushels, 90 cents per bushel for the next 50 bushels, and 95 cents per bushel for all bushels picked over 100.

Thus, First 50 bushels: 0.80 x 50 = 40

Next 50 bushels: 0.90 x 50 = 45

Remaining bushels: 0.95 x 28 = 26.6
