(−3x^2+5x-2)-2(x^2 — 2x − 1) In the expression above is rewritten in form ax^2+ bx +c, where a, b, and c are constants, what is the value of b?
Answer:
value of (b) will be: 9
Step-by-step explanation:
Answer:
b = 9
Step-by-step explanation:
(-3x² + 5x - 2) - 2(x² - 2x - 1) =
= -3x² + 5x - 2 - 2x² + 4x + 2
= -5x² + 9x
= ax² + bx + c
a = -5; b = 9; c = 0
Answer: b = 9

The histogram shows the scores on a recent science test.
Using the histogram, select all of the true statements that describe the data.
(Pls help the correct answer gets brainiest)
Also, remember to look at all the pages.
And their is more than one answer
Answer:
Answer In Explanation
Step-by-step explanation:
O More Than Half Of The Students Scored 81 Or Better
O The Same Number Of Students Scored Between 81 And 90 On The Test As Scored Between 61 And 80
-The Last One Is Confusing Because It Doesn't Say 71-80
Options (B) and (D) are true statements that describe the data in the histogram are the correct answers.
What is a histogram?A histogram is a visual way to display frequency data using bars. It is a chart that shows frequencies for intervals of values of a metric variable. It is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
For the given situation,
The histogram shows the scores on a recent science test.
We need to check the options, which statements describe the data.
Option A: Only two students scored less than 71 on the test.
There are four students scored less than 71.
So option A is false.
Option B: More than half of the students scored 81 or better on the test.
Students scored more than 81 = \(16+8\)
⇒ \(24\)
Total number of students = \(40\)
Half of the students = \(\frac{40}{2}\)
⇒ \(20\)
Thus, \(24 > 20\)
So option B is true.
Option C: More students scored between 91 and 100 on the test than scored between 71 and 80.
Students scored between 91 and 100 = \(8\)
Students scored between 71 and 80 = 12
⇒ \(8 < 12\)
So option C is false.
Option D: The same number of students scored between 81 and 90 on the test as scored between 61 and 80.
Students scored between 81 and 90 = \(16\)
Students scored between 61 and 80 = \(4+12\)
⇒ \(16\)
Thus, \(16=16\)
So, option D is true.
Option E: There were 12 students who scored 80 on the test.
The score range is between 71 to 80. So we could not predict the number of students who score 81.
So option E is false.
Hence we can conclude that options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

Tom wants to save $846, he already has $87, and he deposits $23 each month, M. C. Tom wants to save $87, he already has $846, and he deposits $23 each month, M. D. Tom wants to save $846, he already has $23, and he deposits $87 each month, M.
Answer:
The answer is C.
Answer:
B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.
Step-by-step explanation:
$846 = $87 + $23M
The $846 represents the amount that he wants to save. $23M represents how much money he wants to deposit every M months. $87 represents the amount that he has already deposited (the constant).
And so, the correct answer will be B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

Step-by-step explanation:
probability of an event = # times event has happened / total number of events
probability of someone liking potato chips or pretzels = # of people who like potato chips or pretzels / # total number of people
# of people who like potato chips or pretzels = # people who like potato chips + # people who like pretzels (this works because the two groups don't overlap)
(12+14)/50 = 26/50 = 13/25 = B
Please help and you get a cake
Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values
( has a photo ) Mary is planning a costume party. She spent $375.00 as shown on the graph. How much of the money was spent, to the nearest dollar, on the following items?
1) On decorations?
2) On food?
3) On party hall rental?
4) On prizes?
5) On invitations?
Use the graph below to answer problems 6-10.
( thank you for the help<3 )
Answer: $30 on decorations, $65 on food, $80 on party hall rental, $30 on prizes, and $45 on invitations.
Step-by-step explanation:
Hello! You are told that she has spent $375.00. You know she spent $40 on costumes, $30 on prizes, $65 on food, $45 on candy, $80 on party hall rental, $40 on music, and $45 on invitations. You can fill what you know in for food, party hall rental, prizes, and invitations. You still don't know how much Mary spent on decorations though. To find this information out. Add all of the amounts that you already know and subtract the total from 375 to find the remaining amount Mary spent for decorations. 30 + 65 + 45 + 80 + 40 + 40 + 45 = $345. Subtract 345 from 375. 375 - 345 = 30. Your final answer is she spent $30 on decorations. Hope this helps you out! :)
The Taft Public Library is a library built in the shape of a square. The checkout desk is located in the center of the building. You have been asked to help make a map of the library, using a coordinate plane. Since the library is 100 feet on each edge, you have decided to use a coordinate plane from -10 to 10 on each axis. Each unit represents 5 feet. The y-axis runs north-south, and the x-axis runs east-west.
The children's section is rectangular and has three of its corners at (-10,10), (-10,4), and (-3,10). What are the coordinates of the remaining corner?
The answer is (-3,4)

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
