Answer: question 1) 12
question 2) 3.3 (repeating)
Step-by-step explanation:
question 1) count x axis (goes from 3 to 5 so 2) the count y axis (36 to 60 so 24) so do y/x or 24/2 which equals 12
question 2) x axis = 6-1.5 aka 4.5 y axis= 20-5 aka 15 y/x aka 15/4.5 which gives you 3.333333333333

The price of a technology stock was $9.79 yesterday. Today, the price fell to $9.66. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answers
Answer: 1.3%
Step-by-step explanation:
The percentage decrease can be found using the formula:
percentage decrease = [(original value - new value) / original value] x 100%
Substituting the given values:
percentage decrease = [(9.79 - 9.66) / 9.79] x 100%
percentage decrease = 1.33%
Rounding to the nearest tenth of a percent, the percentage decrease is 1.3%.
Answer: hope this helps ♡
The percentage decrease is 1.33%.
Step-by-step explanation:
Percentage decrease: dividing the value by the total value and then multiplying it by 100
Total value: $9.79 Value: $9.79 - $9.66 = 0.13
[tex]\frac{0.13*100}{9.79}[/tex] =
(0.13 × 100) ÷ 9.79 =
13 ÷ 9.79 =
1.32788559755 ≈ 1.33%
A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.
If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?
Answers
Answer: 900
Step-by-step explanation:
If 24 out of 80 students are undecided, that is 24/80, or 3/10 (0.3).
To find how many would be undecided out of 3,000 students, multiply 3/10 by 3,000/1, and you get 900, which is your answer
Answer:
900
Step-by-step explanation:
A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.
If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?
we can solve with an equation
80 : 24 = 3000 : x
x = 24 * 3000 : 80
x = 900

Solve the inequality d/4 > 36 for d
A. d < 9
B. d < 144
C. d > 144
D. d > 9
Answers
Answer: D. d > 9
Step-by-step explanation:
We have the inequality:
d/4 > 36
To solve for d, we need to isolate the variable d on one side of the inequality. We can do this by multiplying both sides of the inequality by 4:
d > 36 x 4
d > 144
Therefore, the answer is (D) d > 9, since any value of d greater than 9 would satisfy the inequality. We can also check that the other answer choices are incorrect:
If d < 9, then d/4 < 9/4, which is less than 36. So, (A) d < 9 is not a valid solution.
If d < 144, then d/4 < 144/4 = 36, which is less than 36. So, (B) d < 144 is not a valid solution.
If d > 144, then d/4 > 144/4 = 36, which satisfies the inequality. So, (C) d > 144 is also a valid solution, but not the most inclusive one.
Answer:
the correct answer is option C: d > 144.

Answers
Answer:
Melvin can only visit the gym twice if he cannot spend more than $125.00.
Step-by-step explanation:
$49.95+3.95=$53.9
$53.9x2=$107.8
If he were to visit the gym three times, he would pay $161.7. Therefore, he can only visit the gym twice to stay in his price range.

Haven't done this kinda problem in a while but I got 4/3 cm/s
Step-by-step explanation:
Using the coordinates given i put them into the formula:
y1 - y2
m=_________
x1 - x2
That gave me -16/-12, I simplified & got 4/3.
To find the slope you need at least two points on a line
The formula would be m=y2-y1/x2-x1
16-0/12-0
16/12
Simplified we would divide by 4 since it goes into both numbers

Luke has 1/5 of a package of dried apricots. He divided the dried apricots equally into 3 small bags. Luke gives one of the bags to a friend and keeps the other two bags for himself, what fraction of the original package of dried apricots did Luke keep for himself? (answer in simplest form)
Answers
Answer:
Luke kept 1/3 to himself
Step-by-step explanation:
Therefore, Luke gives 1/15 to his friend.
Second step: 1/5 minus 1/15 equals to 2/15.
So, we can come to a conclusion that Luke kept 2/15 for himself.

What is the most appropriate measure of center for the data set about 7th graders?
A)mean
B)median
C)range
D)IQR
Answers
Answer:
The most appropriate measure of center for the given data set about 7th graders is the median (option B).
Step-by-step explanation:
The median is the middle value in a data set when the values are arranged in ascending or descending order. It is not affected by extreme values or outliers. There is an outlier in this case (180), which could alter the mean and represent the data inaccurately. The range does not give a measure of center but instead represents the spread of the data. The IQR is a valuable measure for understanding the spread of data and identifying potential outliers but is not suitable for describing the central tendency or average of the data.
a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?
Answers
The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.
So, the confidence interval is:
178.6 ± 45.2
To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:
(178.6 + (178.6 - 45.2)) / 2 = 311.6
Therefore, the estimated number of students per grade level in the state is 311.6
