Answer:
x=-7
Step-by-step explanation:
8x - 2 = -11 + 7x + 2
First, separate the terms: move x to one side
subtract 7x from both sides
8x -7x - 2 = -11 + 7x -7x + 2
x - 2 = -11 + 2
Now get x by itself by adding 2 to both sides
x - 2 +2 = -11 + 2 +2
x = -11 + 4
simplify
x = -7

(x+2)^2+1=50
this is solving quadratic functions by square roots
Answer:
x = -9 and x = 5
Step-by-step explanation:
[tex] {(x + 2)}^{2} + 1 = 50[/tex]
[tex] = {x}^{2} + 4x + 4 + 1 = 50[/tex]
[tex] = {x}^{2} + 4x + 5 = 50[/tex]
[tex] = {x}^{2} + 4x + 5 - 50 = 0[/tex]
[tex] = {x}^{2} + 9x - 5x - 45 = 0[/tex]
[tex] = x \times (x + 9) - 5(x + 9) = 0[/tex]
[tex] = (x + 9) \times (x - 5) = 0[/tex]
[tex] = x + 9 = 0[/tex]
[tex] x - 5 = 0[/tex]
[tex] = x = - 9[/tex]
[tex]x = 5[/tex]

A student measures which method of taking notes improves grades more, using a computer or a pencil and paper. What type of study is described?
Answer:
Everybody takes notes, or at least everybody claims to. But if you take a close look, many who are claiming to take notes on their laptops are actually surfing the Web, and paper notebooks are filled with doodles interrupted by a couple of random words with an asterisk next to them reminding you that “This is important!” In college, these approaches will not work. In college, your instructors expect you to make connections between class lectures and reading assignments; they expect you to create an opinion about the material presented; they expect you to make connections between the material and life beyond college. Your notes are your road maps for these thoughts. Do you take good notes? After learning to listen, note taking is the most important skill to ensure your success in a class.
Effective note taking is important because it:
Supports your listening efforts.
Allows you to test your understanding of the material.
Helps you remember the material better when you write key ideas down.
Gives you a sense of what the instructor thinks is important.
Creates your “ultimate study guide.”
Effective note-taking helps students retain what they learned in class so that they can use the material to study and build their knowledge and tackle more complex concepts later on. In fact, research indicates that there’s a 34 percent chance that students will remember key information if it’s present in their notes but only a 5 percent chance if it’s not. It doesn’t matter whether you prefer to write brief summaries or make visual guides and diagrams in your notes. The important thing is to find a note-taking strategy that works for you.
There are various forms of taking notes, and which one you choose depends on both your personal style and the instructor’s approach to the material. Each can be used in a notebook, index cards, or in a digital form on your laptop. No specific type is good for all students and all situations, so we recommend that you develop your own style, but you should also be ready to modify it to fit the needs of a specific class or instructor. To be effective, all of these methods require you to listen actively and to think; merely jotting down words the instructor is saying will be of little use to you.
The following are a few recommendations to try out:
Stay organized: Keep your notes and handouts separate for each class. For example, you might have a different notebook and folder for each class or a large notebook with a different tab for each class. This will save you the time of trying to organize and locate your notes when studying for an exam.
Use your paper: Many students try to fit all of a day’s class notes onto one page and are often left with many extra blank pages in their notebooks. Instead, every time your instructor changes topics, flip to a new page. This allows you to find the material easily and makes your notes much cleaner.
Use visual cues: Try highlighting, underlining, or drawing arrows or exclamation points next to any main or difficult concepts. This will call attention to these sections and remind you to spend more time reviewing them.
Group together similar concepts: Grouping or “chunking” material is a good way to make studying and memorization easier. You can try drawing the main concept and connecting it to smaller, related concepts or making an outline of the information. Either one can serve as an effective study guide.
Make notes legible: Some people have messy handwriting. However, writing as clearly as possible when you take notes will make it easier to review them later. It’s also helpful if you’re asked to share your notes with another student who missed class. If laptop use is permitted during class, you can also type your notes.
Step-by-step explanation:
Albert made 6 pies. There were 9 slices in each strawberry pie and 8 slices in each blackberry
pie. If Albert made 50 slices of pie in total, how many of each type of pie did he make?
strawberry pies__
blackberry pies___
No links please!
Thank you
Answer:
2 strawberry
4 blackberry
Step-by-step explanation:
s = number of strawberry pies
b = number of blackberry pies
s + b = 6, then s = 6 - b
9s + 8b = 50
substitute for s:
9(6 - b) + 8b = 50
54 - 9b + 8b = 50
54 - b = 50
subtract 54 from each side of the equation:
-b = -4
multiple both side by -1:
b = 4
s = 6 - 4 = 2

Answer:
number 1 the outliers....................
Answer: B) The distribution is symmetric
Explanation:
The center of the distribution is the highest point. As you move to the left or right, the heights of each bar steadily decrease. Notice that the right hand side is a mirror copy of the left hand side. This mirroring is exactly what it means to be symmetric. If we had outliers, then we'd have bars that are further away from the main group, but we don't have such a thing happening here.
If the distribution was skewed left, or negatively skewed, then we'd have outliers that are smaller than the main group. On the other hand, if we had a skewed right (positively skewed) distribution, then we'd have outliers larger than the main group. We don't have any of these cases happening, so that's why the data isn't skewed in any way.

In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place?
Answer:
the 9 in the tenths place is 10 times more than the one in the hundredths place
Step-by-step explanation:
Given that
There is a number i.e. 3.9928
Here we need to compare the value of the 9 in the tenth place to the value of the 9 in the hundredth place
The 9 in the tenth place has a value of 0.9
And, The value of 9 in the hundredth place contains a value of 0.09
So,
= 0.09 ÷ 0.9
= 0.1
= 1 ÷ 10

Answer:
The length of the box is 6 cm. The width of the box is 3 cm. The height of the box is 2 cm.
Step-by-step explanation:
volume = length x width x height In this instance volume = 36 m³. I will let “b” be the length of the box. “w’ will be the width of the box. And “h” will be the height of the box. Therefore we know that b = 2w and b=3h. So: w= b /2 and h=b /3.
36 m³= b(b/2)(b/3)
36 = b³/6
b ³ = 216
b = 6
w = 6/2 = 3
h = 6/3 = 2

The 42 students on the conservation trip picked up trash at the beach. The girls picked up 15 pounds each and the boys picked up 12 pounds each for a total of 576 pounds. Use b and g for each of the equations.
Answer: number of boys = 18
Number of girls = 24
Step-by-step explanation:
Based on the information given, we can form this into an equation which will be:
b + g = 42 ....... i
12b + 15g = 576 ...... ii
Multiply equation i by 12
Multiply equation ii by 1
12b + 12g = 504 ....... iii
12b + 15g = 576 ........ iv
Subtract iii from iv
3g = 72
g = 72/3
g = 24
Since b + g = 42
b + 24 = 42
b = 42 - 24.
b = 18
Therefore, number of boys = 18
Number of girls = 24

A) 7.75
B) 8.50
C) 9.25
D) 10.75
The interquartile range of the data will be 9.1.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The table shows the blood pressures of 16 clinic patients.
Now,
Since, The data set is,
⇒ 81.6, 84.1, 87.6, 82.8, 82.0, 88.9, 86.7, 96.4, 84.6, 104.9, 90.8, 94.0, 69.4, 78.9, 75.2, 91.0
Arrange in ascending order as;
⇒ 69.4, 75.2, 78.9, 81.6, 82.0, 82.8, 84.1, 84.6, 86.7, 87.6, 88.9, 90.8, 91.0, 94.0, 96.4, 104.9
Clearly, There are 16 clinic patients.
Hence, The lower quartile (Q₁) = 81.6 + 82 / 2
= 81.8
And, The Upper quartile (Q₃) = 90.8 + 91 / 2
= 90.9
Thus, The interquartile range of the data = Q₃ - Q₁
= 90.9 - 81.8
= 9.1
Therefore, The interquartile range of the data = 9.1
