Answer:
The correct mean is -12.5.
Step by step explanation:
If one of the 20 observations is a negative number, then the mean would be negative. This is because, when a negative number is in contact with (meaning added, subtracted, multiplied by) a positive number, the whole answer is negative, because it's opposite signs.
Hope this helps! :D
Use the equation y = x - 2 and perform a reflection over the x-axis. Write an equation in 2
1
slope intercept form that represents the new line.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
y=x-2
We know that Reflecting over the x-axis inverts the sign of the y-coordinate.
Thus, after reflecting over the x-axis, the equation would be:
-y = x - 2
Now, writing the equation in the slope-intercept form
y=mx+b
where
m is the slope and b is the y-interceptso the equation in the slope-intercept form
-y = x - 2
y = -x + 2
Here,
The slope = m = -1The y-intercept = b = 2Zane took three typing tests and recorded the results as shown.

What was Zane's unit rate, in words per minute, on each test?
On which test does Zane have the highest unit rate?
Numbers aren't arranged properly so I'll try and do this. Please follow method as answer might differ cause of this
Test Number of Words Time(minutes)
A. 30. 4
B. 78. 15
C. 99. 22
Answer:
Step-by-step explanation:
To calculate Zane's unit rate/number of words per minute for which each test, we divide number of words in each test by time taken for that test
For test A, unit rate = 30 words/ 4 minutes = 7.5 words per minute
For test B, unit rate = 78 words/15 minutes = 5.2 words per minute
For test C, unit rate = 99 words/22 minutes= 4.5 words per minute
From the above Zane has the highest unit rate in test A and is therefore fastest in test A

The Pythagorean Theorem can be used in many real-world scenarios.
Part 1
Write your own real-world scenario where the Pythagorean Theorem can be applied to find a missing piece. You may choose to write a problem that is two- or three-dimensional in nature. Be sure that you will be able to draw a diagram of your scenario.
Write out your problem and submit it for Part 1. Be sure to end your scenario with a question.
Part 2
Draw a diagram of the scenario you created in Part 1. You may draw by hand and scan and upload your drawing or create a computer-generated drawing for submission. Be sure to label all parts and dimensions of the drawing.
Part 3
Solve the question that you posed in Part 1. Show all of your steps in answering the question.
For this option, you will need to submit all three parts for full credit—your real-world problem and question, the diagram that you created, and your work solving the problem, showing all steps.
Answer:
Step-by-step explanation:
Part 1- Some sort of dimensions of a table top in a kitchen, and you need the "hypotenuse" of the table top.
Part 2- Draw a right triangular table top complete with drawers under it, and stuff. Of course label it.
Part 3- Solve your question

how to solve this 2x+x-4y
Answer:
Combine like terms
2 + − 4
3x − 4y
Answer:
[tex]3x-4y[/tex]
Step-by-step explanation:
[tex]2x+x-4y[/tex]
If a term doesn't have a coefficient , it is considered that the coefficient is 1
[tex]2x+1x-4y[/tex]
Why is it considered that the coefficient is 1?
Remember that any term multiplied by 1 remains the same:
[tex]1.x=x[/tex]
Step 1
The equality can be read in the other way as well , so any term can be written as a product of 1 and itself:
[tex]x=1 . X \\[/tex]
Step 2
Usually, we don't need to write multiplication sign between the coefficient and the variable , so the simpler form is:
[tex]x=1x[/tex]
That is why we can write the term without the coefficient as a term with coefficient 1.
Let's go back to your problem now
Collect like terms by adding their coefficients

Which are correct representations of the inequality 6x2 3 + 4(2x - 1)? Select three options.
Answer:
Option A, B, and C.
Step-by-step explanation:
Given, 6x ≥ 3 + 4(2x - 1),
Solve to find the correct representations given in the options.
6x ≥ 3 + 4(2x - 1)
Apply distributive property
6x ≥ 3 + 8x - 4 (option B is correct) ✅
Add like terms
6x ≥ -1 + 8x
Add 1 to both sides
6x + 1 ≥ 8x
Subtract 6x from each side
1 ≥ 8x - 6x
1 ≥ 2x (option A is correct) ✅
Divide both sides by 2
1/2 ≥ 2x/2
½ ≥ x
½ ≥ x means all possible values of x are less than 0.5. representing this inequality on a graph, we would have the directed line starting at 0.5 moving towards our left.
This make option C correct.✅
What is the value of x in the equation below?
29.46=13.82+4x
Answer:
x=3.91
Step-by-step explanation:
29.46=13.82+4x
13.82+4x=29.46
subtract 13.82 from both sides
4x=15.64
divide by 4
x=3.91

Write the
equation that describes that function.
Express it in slope-intercept form.
Answer:
y = 1/2x + 3Step-by-step explanation:
As per graph, using the points (-6, 0) and (0, 3) we determine that:
the y-intercept is 3 and the slope is m = (3-0)/(0 - (-6)) = /3/6 = 1/2So the equation is:
y = mx + by = 1/2x + 3(From MATH workbook 8A)

4 cups of peanut butter is needed to make 80 cookies how many cups of peanut butter would be needed to make 400 cookies
Answer:
20 Cups of peanut butter
Step-by-step explanation:
You take 400 divided by 80, which would give you 5, multiply that by the number of cups (4x5) and you final answer will be 20.Answer:
20 cups
Step-by-step explanation:
80 cookies are made by 4 cups
which means 1 cookie is made by
[tex] \frac{4}{80} cups[/tex]
Therefore 400 cookies would require
[tex]400 \times \frac{4}{80} cups = 20cups[/tex]

The value is approximate.
==========================================================
Explanation:
Focus on the upper triangle.
Label the unknown horizontal side as y
Use the pythagorean theorem to solve for y
a^2+b^2 = c^2
10^2 + y^2 = 26^2
100+y^2 = 676
y^2 = 676-100
y^2 = 576
y = sqrt(576)
y = 24
-----------
Now move to the bottom triangle
With respect to the reference angle, the side y = 24 is opposite this. The hypotenuse is unknown.
Use the sine rule to connect the two and solve for x
sin(angle) = opposite/hypotenuse
sin(32) = y/x
sin(32) = 24/x
x*sin(32) = 24
x = 24/sin(32)
x = 45.2899179551967 which is approximate
x = 45 rounding to the nearest whole number
Side x is approximately 45 cm long.
Note: make sure your calculator is in degree mode.
1. The measure of the largest angle of a triangle is 12 degrees less than the sum of the measures of the other two. The smallest angle measures 58 degrees less than the largest. Find the measures of the angles.
