What is an equation?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
Total = $40 + $45 + $26.6 = $111.6

about 5% of americans have blue eyes. suppose 3 people are selected at random from the us population. what is the probability that all 3 have blue eyes?
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.

The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Use the constraints of the real-world situation to predict the height of the water balloon at 15 seconds. Use complete sentences to support your answer.
From the linear model we can see that the height of the balloon after 15 seconds is 0 feet.
Depending on the context, the phrase "linear model" is used differently in statistics.
The word is frequently used interchangeably with a linear regression model since it occurs most frequently in relation to regression models. The phrase has a different connotation when employed in time series analysis, though. The term "linear" is used in each instance to denote a subclass of models for which a significant decrease in the complexity of the underlying statistical theory is feasible.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.
At about 10 seconds the balloon falls on the ground and splashes.
Hence for further time the balloon is always at the ground.
Therefore at time of 15 seconds the height of the balloon is always 0 feet as represented in the linear model.

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
How is it 840g plsss help!
Step-by-step explanation:
Let's say first piece is x. First and third ratio is 1:4 so it would be
4x - x = 360
3x = 360
x = 120 Third piece is 120g. Now we just multiply the rest.
2 × 120 = 240g
4 × 120 = 480g, total 840g
Answer:
840 g
Step-by-step explanation:
Ratio:Ratio of weight of 3 pieces = 1 : 2 : 4
Weight of 3 pieces = x , 2x , 4x
Weight of third piece - weight of first piece = 360 g
4x - x = 360
3x = 360
Divide both sides by 3,
x = 360÷ 3
x = 120 g
Weight of first piece = x = 120 g
Weight of second piece = 2x = 2*120 = 240g
Weight of third piece = 4x = 4 *120 = 480 g
Weight of the whole cake = 120 + 240 + 480
= 840 g

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

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]
Find an equation in the form y=mx + b
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)
A normally distributed data set of 600 values has a mean of18.5 and a standard deviation of 3.25.What is the approximate number of values in the dataset expected to be 22 or greater?
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,
[tex]z=\frac{x-\mu}{\sigma}[/tex]So the probability is calculated as,
[tex]\begin{gathered} P(X\ge22)=P(z\ge\frac{22-18.5}{3.25}) \\ P(X\ge22)=P(z\ge1.08) \\ P(X\ge22)=P(z\ge0)-P(0\leq z\leq1.08) \\ P(X\ge22)=0.5-\emptyset(1.08) \end{gathered}[/tex]From the Standard Normal Distribution Table,
[tex]\emptyset(1.08)=0.3599[/tex]Substitute this value,
[tex]\begin{gathered} P(X\ge22)=0.5-0.3599 \\ P(X\ge22)=0.1401 \end{gathered}[/tex]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.
The area of a square field is 3.24hectares . Find its perimeter in decimeters
The filed has a perimeter value of 720000 decimeters
How to determine the perimeter of the field?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
