Answer:
21.9 mean
22 median
43 range
5, appeared 3 times mode
Step-by-step explanation:
Answer:
mean: 21.9 median: 22 mode: 5 range: 43
Step-by-step explanation:
First you put all the numbers from least to greatest.
5, 5, 5, 16, 16, 28, 29, 32, 35, 48
To calculate mean, you add all of the numbers together and divide by the amount of numbers you have in your data set.
5 + 5 + 5 + 16 + 16 + 28 + 29 + 32 + 35 + 48 = 219
219 ÷ 10 = 21.9
So the mean is 21.9
The median is your middle number in your data set. if your data set has an odd set of numbers (as in the amount of numbers, not the actual numbers in your data set) it would be the number right in the middle; no extra work needed. However, if your data set has an even set of numbers you would have to take to two middle numbers and find the average of those two numbers.
Since your data set has an even amount of numbers that means we have to do it the more tedious way.
Your two middle numbers are 16 and 28, so to find the average of those two numbers we would first have to add them together.
16 + 28 = 44
Then we would have to divide it by 2.
44 ÷ 2 = 22
So, you median will be 22.
To find your mode, you first need to count how many times each number is repeated.
5 - three times
16 - two times
28 - one time
29 - one time
32 - one time
35 - one time
48 - one time
Your mode will be the number(s) who has/have repeated the most.
So, your mode is 5.
To find your range, all you need to do is subtract your lowest number from your highest number. Since your lowest number is 5 and your highest number is 48, all you need is to subtract these two number, and you have your range.
48 - 5 = 43
So, your range is 43.

The Chemistry Club is experimenting with different mixtures of water with a certain chemical (sodium polyacrylate) to make fake snow.
To make each mixture, the students start with some amount of water, and then add of that amount of the chemical, and then 9 more grams of the chemical. The chemical is expensive, so there can’t be more than a certain number of grams of the chemical in any one mixture.

how do you divide a square in half by connecting two vertices?
Answer:
diagonally.
Step-by-step explanation:
the vertices are the corners or angles. square has four angles. if you have to divide it in half by connecting 2 vertices, then you would just need to draw a line from one corner, diagonally to another corner. you have 2 halves that are equilateral triangles. think about a grilled cheese sandwich cut in half. make sense?

Members of a bowling league play thousands of combined games over the course of a season. Suppose that the scores of individual games have a known standard deviation of σ=30 pins. Isla plans on taking a random sample of n games from this population to make a 95% confidence interval for the mean score. She wants the margin of error to be no more than 10 pins. Which of these is the smallest approximate sample size required to obtain the desired margin of error?

Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 68 inches and the standard deviation is 4 inches, 68% of the population will have a height within which of the following ranges?
Answer:
68% of the population will have a height between 64 and 72 inches
Step-by-step explanation:
According to the Empirical Rule, 68% of the population will have a height within the range of 1 standard deviation of the mean. This means that the range of possible heights for 68% of the population is between 68-4(1)=64 inches and 68+4(1)=72 inches
Which inequality is equivalent to |x-4/<9?
- 9> X-4 < 9
0.9< X - 4 < 9
OX-4<-9 or X-4 < 9
X – 4 >-9 or x 4 < 9
Answer: x-4>-9 or x-4<9
Step-by-step explanation:
The correct option for the given inequality is x-4>-9 or x-4<9
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given an inequality, |x-4| < 9
Using the rule, if |x| < a then, -a < x < a.
Therefore,
|x-4| < 9
-9 < x-4 < 9
x-4 > -9 or x-4 < 9
Hence, The correct option for the given inequality is x-4>-9 or x-4<9

Why should you write everything down instead of doing the math in your head?
Answer and Step-by-step explanation:
It ensures that you don't accidently skip a step or get confused by which numbers are being used. By writing it down, it allows you to look back and see if you answer was correct or incorrect.
For example:
On a test, you need to do a complicated math problem that you know you can do in your head. It would still be a good idea to write down the process, so that you can see in front of you the numbers you get and results. If it is incorrect when checking over you answers, then you can go through the steps you made to see where you made a mistake.

Which pair of triangles can be used to show that the slope of line a is the same anywhere along the line?
Answer:
C
Step-by-step explanation:
The pair of triangles in option C (image attached below) shows that the slope of line a is the same anywhere on the line.
Let's check it out:
Slope = rise/run
✔️For the first lower triangle:
Rise = 3.5
Run = 4.5
Slope = 3.5/4.5 ≈ 0.8
✔️For the second upper traingle:
Rise = 4
Run = 5
Slope = 4/5 = 0.8
Therefore, it shows that the slope of the line is the same anywhere along the line of the graph.

write the slope-intercept form of the equation of each line.
Answer:
[tex]y=2x+3[/tex]
Step-by-step explanation:
1. Approach
Slope intercept form is a way of expressing an equation of a line using the slope of a line, and its y-intercept. The general format for the equation of a line in slope-intercept form is the following,
[tex]y=mx+b[/tex]
Find each of the missing pieces of information and substitute it into the equation to find the equation of the line.
2. Find the slope
The slope of a line is the change in the line is can be found using the following formula,
[tex]\frac{y_2-y_2}{x_2-x_1}[/tex]
As one can see on the given graph, two points on the line are the following,
[tex](-2, -1), (-1, 1)[/tex]
Substitute the points into the formula and solve for the slope,
[tex]\frac{(1)-(-1)}{(-1)-(-2)}[/tex]
[tex]=\frac{2}{1}\\\\=2[/tex]
3. Find the y-intercept
The y-intercept of a line is where the line intersects the y-axis. As one can see this point is the following,
[tex](0,3)[/tex]
Thus the y-intercept is (3).
4. Put the information together
Putting all of this information together, substitute the found information into the general equation for slope-intercept form. One can see that the equation of a line is the following,
[tex]y=2x+3[/tex]
In a children's story, a young girl finds that one bowl of soup is too hot, another is too cold, and a third bowl is just
right. Further study reveals that the temperature of the soup bowl that the young girl declared to be just right was
100°F. A researcher would like to test the hypotheses How=100 versus Hou* 100 where ji = the true mean
temperature of all bowls of soup. A 95% confidence interval based on a random sample of 30 bowls of soup is
(100.9, 102.3). Using this interval, can the researcher reject the null hypothesis?
Yes, the null hypothesis can be rejected at the significance level a = 0.05, because 100 is not contained in the and
95% confidence interval.
Yes, the null hypothesis can be rejected at the significance level a = 0.01, because 100 is not contained in the
95% confidence interval.
No, the null hypothesis cannot be rejected at the significance level a = 0.05, because 100 is not contained in the
95% confidence interval.
No, the null hypothesis cannot be rejected at the significance level a = 0.01, because 100 is not contained in the
95% confidence interval
Answer:
A, Yes, the null hypothesis can be rejected at the significance level α = 0.05, because 100 is not contained in the 95% confidence interval.
