I need help with this math equations.
Answer:
2: (2, 0)
Step-by-step explanation:
Since 2 is x and 0 is y, you would put those numbers in the equation. These 2 numbers work for both equations so it is the correct answer.
Answer: Option 2 - (2,0)
Step-by-step explanation:
By substituting the values of x and y only option 2 is appropriate for the equation to be true.
Two factory plants are making TV panels. Yesterday, Plant A produced 4 times as many panels as Plant B. Three percent of the panels from Plant A and 2% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 1260 defective panels?
Answer:
Step-by-step explanation:
x=# of panels plant B produced
3x=# of panels plant A produced
2%(x)+5%(3x)=1360
0.02(x)+0.05(3x)=1360
0.02x+0.15x=1360
0.17x=1360
17x=136,000
x=136,000/17
x=8,000 panels were produced by plant B

Which of the following sentences correctly uses parallel structure? In the scientific method, you propose a hypothesis, conduct an experiment, analyze the data, and you end with a reporting of your findings. The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings. The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings. To correctly follow the scientific method, you must hypothesize, experiment, analyze, and reporting your findings.
Answer & Step-by-step explanation:
The following sentence correctly uses parallel structure: "The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings." In this sentence, all of the phrases are in the same form and describe actions that are part of the scientific method. Each phrase begins with a verb (proposing, conducting, analyzing, and reporting) and is followed by a noun that describes the action (hypothesis, experiment, data, and findings). This structure is parallel because each phrase has the same grammatical structure and describes a similar action.
The other sentences do not use parallel structure because they do not have the same grammatical structure or they do not describe similar actions. For example, in the first sentence, the phrases "propose a hypothesis" and "end with a reporting" are not parallel because they do not have the same grammatical structure. In the second sentence, the phrases "proposing your hypothesis" and "reporting your findings" are not parallel because they do not describe the same type of action (proposing is a mental process, while reporting is a physical action). In the third sentence, the phrases "begins with a hypothesis" and "reporting findings" are not parallel because they do not have the same grammatical structure (one begins with a verb and the other ends with a verb). Finally, in the fourth sentence, the phrases "hypothesize" and "reporting" are not parallel because they do not have the same grammatical structure (one is a verb and the other is a gerund).
Answer:
The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings
Find the area, please show your work
Answer:
25
Step-by-step explanation:
8 x 4 / 2 gets you the area of the big triangle, which is 32 / 2 = 16
1 x 8 for the rectangle, so far you're at 16 + 8 = 24
The tiny triangles are half the squares so add them together ( 1/2 + 1/2) to get 2/2 = 1/1
add them together to get 24 + 1 = 25
You can also do it as if you take the big triangles and add them together to get a square, you get a 4 x 4 square
Then you have the 1 x 8 rectangle
do the same thing with the tiny triangles as the big triangles, and you get 1
(4 x 4) + (1 x 8) + 1
16 + 8 + 1
24 + 1 = 25

A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest tenth. Using this equation, estimate the homework grade, to the nearest integer, for a student with a test grade of 31.
Homework Grade (x) Test Grade (y)
58 52
75 66
66 68
85 74
52 38
74 65
78 76
The linear regression equation that represents this set of data is given as follows:
y = 1.05x - 10.43.
The estimated homework grade for a student with a test grade of 31 is given as follows:
39.46.
How to find the equation of linear regression?To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.
The points for this problem are given as follows:
(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).
Inserting these points into a calculator, the equation is given as follows:
y = 1.05x - 10.43.
The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:
31 = 1.05x - 10.43
x = 41.43/1.05
x = 39.46.

Answer:
40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:
40
Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.
Then you will get 40 degrees as your answer.

Step-by-step explanation:
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Answer:
\(x=\frac{-b\pm \sqrt{b^{2}-4ac } }{2a}\)
Step-by-step explanation:
If a quadratic equation is in the form of ax²+ bx + c = 0
Then the roots of this quadratic equation can be obtained by,
1). Factoring the expression.
2). By quadratic formula.
If we use the method to get the value of x or roots of the equation,
x = \(\frac{-b\pm \sqrt{b^{2}-4ac } }{2a}\)
where a, b and c are the coefficients used in the quadratic equation.

Answer:
Zero
Step-by-step explanation:
because, if the Discriminant of f is positive, it intersects the x-axis twice; if it’s negative, it intersects the x axis 0 times, but if it intersects the x axis or touches it in 1 point, then the Discriminant is 0!
As you can see in this graph, the x-axis and parabola only touch/intersect in 1 point, so the Discriminant of f is zero
Hope this helps!
Answer: Discriminant is zero
Step-by-step explanation:
If negative, the vertex of the graph will be above the x-axis, if positive it will be below the x-axis, and zero if it is directly on the x-axis.

This quarter circle has a radius of 6 cm. What is approximate area of this figure? Use 3.14 for pi. Round to the nearest hundredth.
Answer:
probably my last question for the day but the answer is 28.26 square centimeters.
Step-by-step explanation:
The formula to find the area of a quarter circle is:
A = (1/4)πr^2
where A is the area and r is the radius.
Substituting the given values:
A = (1/4) × 3.14 × 6^2
A = 28.26
Rounding to the nearest hundredth, the approximate area of the figure is 28.26 square centimeters.
