Answer:
12Step-by-step explanation:
So our equation is:
(7x+5)+(5x+3)+(12x-20) = 276
First remove parenthesis:
7x+5+5x+3+12x-20=276
Combine like terms:
24x-12 = 276
Add 12 on both sides:
24x = 288
Divide:
288/24 = 12

Answers
B. The teacher should pulls sticks with the students names on it, or use a random name generator.

It is not a good method because the first person to walk through the door should be rewarded for being on time and it is pretty much that the first person to walk in is always the first to walk in

Geet sells televisions. He earns a fixed amount for each television and an additional $20 if the buyer gets an extended warranty. If Geet sells 18 televisions with extended warranties, he earns $1,530. How much is the fixed amount Geet earns for each television?
Answers
Answer: $65
Step-by-step explanation: first you want to get rid of the amount in extended warranties, to do this you want to multiply 20 and 18. by doing this you get 360, so subtract 360 from 1530 and you get 1170. To find out the fixed amount per you want to divide by the amount of televisions sold which is 18. So 1170 divided by 18 is 65 so that is the fixed amount.

Which of the following numbers is not part of the solution x ≤ -2
A. -2.45
B. -2
C. -8
D. -1.76
Answers
Answer:
D.
Step-by-step explanation:
In order for it to be the solution, it must be less than or equal to -2. D (-1.76) is bigger than -2, which means it is not a part of the solution.
Answer:
D
Step-by-step explanation:
First of all, let's try all of the options available.
We know that x must be LESS THAN or EQUAL to -2
So, let's get on with it!
Option A:
Is -2.45 LESS THAN or EQUAL to -2?
Well, according to the number line, if the number is left of the number that you are comparing, -2 then it is less than.
So this option is alright.
Option B:
-2 is not LESS THAN but ONLY EQUAL to -2.
So this option I THINK is alright, but am not sure. But I think it is alright because if it is less than and equal to, then that means it ALSO INCLUDES -2.
Option C:
Again, -8 is located to the LEFT side of -2, which means -8 IS LESS THAN or Equal to -2.
So this option is alright.
Option D:
-1.76 is to the RIGHT side of -2, which means it is GREATER than -2.
So this option is CUT OFF
Hope this helps.

The difference between the median and the range in the data set shown below is option A. 5.
The calculation is as follows:Median is 7
As two numbers in the middle should be 8 and 6.
Now

It should be divided by 2 so it comes 7.
The range should be

The list below shows the results of a survey of favorite ice-cream flavors among middle-school students.
18 students voted for chocolate.
12 students voted for strawberry.
20 students voted for vanilla.
What percentage of the students chose vanilla as their favorite ice-cream flavor?
A. 20%
B. 30%
C. 40%
D. 50%
Answers
Answer:
C. 40%
Step-by-step explanation:
There are 18 + 12 + 20 = 50 students in total.
20 students voted for vanilla.
So... 20 out of 50 students voted for vanilla.
20/50 = 2/5
2/5 = 40%
Answer:
C. 40%
Step-by-step explanation:
First you add them together:
12+18+20 = 50
Then, you times both sides of the equation by 2
24+36+40 = 100
You can see that 20 changed to 40, and that's the answer!
Madeline found that the experimental probability of her scoring from a
three-point line in a basketball game is 1/10 or 10%. Out of 20 shots from a
three-point line, about how many points could she predict she would make?
pls help
Answers
Answer:
6 points
Step-by-step explanation:
1/10=x/20cross multiply the x with the 10 and the 20 with the 1 so that you are now left with the fraction 10x/2010x divided by 20 will give you x=2to check and make sure this is still equivalent with the 10% of shots Madeline makes divide 2/20Since this is still 10 percent Madeline makes 2 out of every 20 shots Multiply those 2 shots by three points since it was from the three point line and we get 6 pointsHope that helps :)
Using the binomial distribution, it is found that she would be expected to make 6 points.
For each shot, there are only two possible outcomes, either she makes it, or she misses it. The probability of making a shot is independent of any other shot, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability, which has expected value given by:
[tex]E(X) = np[/tex]
In this problem:
She takes 20 shots, hence [tex]n = 20[/tex].She has a 10% probability of making each shot, hence [tex]p = 0.1[/tex]The expected number of shots she makes is given by:
[tex]E(X) = np = 20(0.1) = 2[/tex]
Since each shot from the three-point line is worth 3 points, she is expected to make 2 x 3 = 6 points.

36 is what percentage of 128?
A.
B. 28 %
C. 28.125 %
D. 4,608%
Answers
Answer:
C is the correct answer:
Solution for 36 is what percent of 128:To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 128 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 128, so we can write it down as 100%=128.
4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.
5. Now we have two simple equations:
1) 100%=128
2) x%=36
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=128/36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 36 is what percent of 128
100%/x%=128/36
(100/x)*x=(128/36)*x - we multiply both sides of the equation by x
100=3.55555555556*x - we divide both sides of the equation by (3.55555555556) to get x
100/3.55555555556=x
28.125=x
x=28.125
now we have:36 is 28.125% of 128
