I'll do the first four problems to get you started
====================================================
Problem 15
Answer: 40%-----------------
Explanation:
The price dropped by $60, since 150-90 = 60. This is the discount, which is the amount you save. Divide this over the original price ($150) and we get 60/150 = 0.40 = 40%
Therefore, the price has been reduced by 40%. If we take 40% of 150, then 0.40*150 = 60 showing that 40% of $150 is 60 dollars. This matches up with the discount value mentioned earlier. So it helps verify the answer.
====================================================
Problem 16
Answer: 20%-----------------
Explanation:
The pay raised by 12-10 = 2 dollars. So the percent increase is 2/10 = 0.20 = 20%
Note how 20% of 10 = 0.20*10 = 2 is the pay raise amount; meaning that 2 is 20% of 10.
====================================================
Problem 17
Answer: 50%-----------------
Explanation:
I'll use a formula this time, but we could follow the same idea as the previous problems. This is to give another approach.
A = old value = 8
B = new value = 12
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (12-8)/8 ] * 100%
C = (4/8)*100%
C = 0.50*100%
C = 50%
50% is the same as half of the value. Note how half of 8 is 4, ie 50% of 8 = 0.50*8 = 4. So this is the amount of increase when going from 8 to 12.
Side note: The "B-A" portion in the numerator represents the change in value. We divide this change over the original amount "A" and then multiply by 100% to get the percent change we're after.
====================================================
Problem 18
Answer: 24%-----------------
Explanation:
I'll use the formula again
A = old value = 3.00
B = new value = 2.28
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (2.28-3.00)/3.00 ] * 100%
C = (-0.72/3.00)*100%
C = -0.24*100
C = -24%
The negative percent change means we have a percent decrease. So we have a 24% decrease. Since your teacher is asking about how much the percent reduction is, we'll write the positive version of this percentage.
Problems 19 through 22 will follow the same ideas as shown in the previous problems.
Three methods for teaching mathematics to first graders are to be compared. Ten students are
randomly assigned to each of the methods, and the score on a quiz is recorded. What are the
response and treatment for this experiment?
Answers
Answer: The three methods are the treatments and the response is the score achieved on the quiz.
Step-by-step explanation:
The three techniques are the treatments, and the results are the final score.
what is response variable in the experiment?
The researcher predicts that a variable will change if the controlled variable changes; this variable is known as a responsive variable. A dependent variable is another name for a responsive variable.
Solution:
Three methods are assigned for teaching mathematics.
Randomly ten students are assigned to each of the method.
There scores are then recorded on a quiz.
It is clear that the response will be the score card of the students either scoring high marks or not being able to clear it.
And the treatments are three for if the student is not able to understand any of the method.
Hence the three methods serve as treatments, and the outcomes determine the final grade.

A professional pool player claims that she sinks at least one ball in a pocket on 80% of her opening break shots. In a recent set of 20 games, she sunk at least one ball on her break shot in only 14 of the games. A simulation of 100 trials was conducted to see how unusual these most recent games are.
Based on the dotplot of the simulation results and the pool player’s last 20 games, which conclusion can be drawn?
The player’s true probability of sinking at least one ball on her break is 27%.
Another 100 simulated trials would show a much different outcome; therefore, we cannot draw any conclusions.
It is most likely that she would sink at least one ball during her break exactly 16 times.
There is about a 27% chance of her sinking at least one ball on her break 14 or fewer times in 20 games. This result is not unusual and there is no convincing evidence that her average is less than 80%.

(i) Rayan scored 30 marks. If she has got 10 correct answers, how many questions has she attempted incorrectly?
(ii) Riya scores 44 marks by attempting 13 questions. How many questions has he attempted correctly and how many has he attempted incorrectly?
Answers
OK ITS OK IM GOD CALM DOWN
Answer:
Step-by-step explanation:
(1)
If she got 10 answers right, she got 5 * 10 = 50 marks before anything was deducted.
Since she wound up with 30 marks, she lost 50 - 30 = 20 marks. If you don't feel comfortable with this, call it -20
Each incorrect answer cost her -2 marks.
Divide -20 /-2 = 10
She has answered 10 questions incorrectly.
(ii)
5x - 2y = 44
x + y = 13 Multiply this equation by 2
2x + 2y = 26
Rewrite the first and third equations
5x - 2y = 44
2x + 2y = 26 Add
7x = 70 Divide by 7
x = 70/7
x = 10
So 10 questions were answered correctly
x + y = 13
10 + y = 13
y = 3
Answer
10 were answered correctly
3 were answered incorrectly

The table shows Kayden's quiz scores for a semester. What are the mean and the standard deviation, rounded to the nearest hundredth, for the quiz data?
45 48 42 47 43
Mean =
Standard deviation =
Answers
Answer:
The mean is of 45.
The standard deviation is 2.28.
Step-by-step explanation:
The mean is the sum of all values divided by the number of values.
The standard deviation is the square root of the sum of the difference squared between each value and the mean, and divided by the number of values.
Mean:
[tex]M = \frac{45 + 48 + 42 + 47 + 43}{5} = 45[/tex]
The mean is of 45.
Standard deviation:
[tex]M = \sqrt{\frac{(45-45)^2 + (48-45)^2 + (42-45)^2 + (47-45)^2 + (43-45)^2}{5}} = 2.28[/tex]
The standard deviation is 2.28.
If 21 is added to a number, the result is 41 less than twice the number. Find the number.
Answers
Answer: 62
Step-by-step explanation: Set up your equation
21+x=2x-41 because the number (x) that 21 is added to is 41 less than (so subtraction) twice (so multiply the number x by 2) the number (x).Get the x's on one side by subtracting the single x21=x-41Now add 41 to both sides to completely isolate x62=xSo, your answer is x=62. The number is 62.Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.
