Answer:
1. Mode = 7
2. Range = 8
Step-by-step explanation:
The following set of data were obtained from the question:
4, 6, 5, 9, 3, 2, 7, 7, 1, 8
Mode =?
Range =?
1. Determination of the mode of the data.
Mode is simply defined as the mark (score) with the highest frequency. Thus we can obtain the mode as follow:
Scores >>>>>>> Frequency
4 >>>>>>>>>>>> 1
6 >>>>>>>>>>>> 1
5 >>>>>>>>>>>> 1
9 >>>>>>>>>>>> 1
3 >>>>>>>>>>>> 1
2 >>>>>>>>>>>> 1
7 >>>>>>>>>>>> 2
1 >>>>>>>>>>>> 1
8 >>>>>>>>>>>> 1
From the above illustration, we can see that the mark 7 has the highest frequency. Therefore, 7 is the mode of the data .
2. Determination of the range of the data.
Range of a given data is simply obtained by calculating the difference between the highest and the lowest score. The range can be obtained as follow:
Highest score = 9
Lowest score = 1
Range = Highest – Lowest
Range = 9 – 1
Range = 8
How did segregation become the key issue in the Plessy v. Ferguson case?
Researchers in New Zealand interviewed 907 drivers at age 21. They had data on traffic accidents and they asked their subjects about marijuana use. Here are data on the numbers of accidents caused by these drivers at age 19, broken down by marijuana use at the same age:
Marijuana Use per year
1-10 11-50 51+
Never times times times
Drivers 452 229 70 156
Accidents caused 59 36 15 50
Required:
a. Explain carefully why a useful graph must compare rates (accidents per driver) rather than counts of accidents in the four marijuana use classes.
b. Compute the accident rates in the four marijuana use classes. After you have done this, make a graph that displays the accident rate for each class. What do you conclude? (You can’t conclude that marijuana use causes accidents, because risk takers are more likely both to drive aggressively and to use marijuana.)
Answer:
a)
Therefore to compare this data effectively using the rates per driver is better off like for people who do not smoke their rate will be = 59 / 452 = 13.1% while for smokers of 61+ times = 50 / 156 = 32.1% and this rate will show clearly tat more accidents where caused by people who smoked 51+ times hence it should be used for graphical representation
b) attached below
Step-by-step explanation:
A) A useful graph is must compare rates rather than counts of accidents in the four marijuana use classes
Using the rates on a graph is better for reference like saying; that 50 crashes were caused by those who smoke 51+ times and 59 crashes is caused by those who never smoke this statistics makes it seem like smoking has no effect on the amount of accidents
Therefore to compare this data effectively using the rates per driver is better off like for people who do not smoke their rate will be = 59 / 452 = 13.1% while for smokers of 61+ times = 50 / 156 = 32.1% and this rate will show clearly tat more accidents where caused by people who smoked 51+ times hence it should be used for graphical representation
B) accident rate for Non-smokers
= (59/452) * 100 = 13.05
accident rate for smokers between 1-10 times
= ( 36/ 229 ) * 100 = 15.72
accidents rate for smokers between 11 - 50 times
= ( 15/50 ) * 100 = 21.42
accidents rate for smokers 51+
= ( 50 / 156 ) * 100 = 32.05
attached below is the required graph
3 Leah surveyed the 35 members of her class to find out their favorite color. She listed this information in the form of a table, as shown here. Favorite Colors Colors Number of Students Choosing Colors Blue 14 Green 5 Yellow 7 Red 3 Orange 1 Maroon 5 Based on this information which is the best estimate of the number of people choosing red as a favorite color from a group of 175 people? (whoever shows work gets brainliest)
Answer:
15.
Step-by-step explanation:
If you add all of the marbles you will get 35 as the total.
Since there are 175 students, we can divided 35 by 175 and safely assume that for every marble, 5 people have chosen it.
This means that there are 3 red marbles, or that 15 people have chosen that marble.

A bakery makes 1,650 cookies in one day. The cookies are put into boxes. A large box contains 24 cookies, and a small box contains 3 cookies. The bakery fills as many large boxes as possible, and then fills as many small boxes as possible.How many small boxes does the bakery fill in one day?
Answer:I think ia 18
Step-by-step explanation:
The number of small boxes the bakery fills in a day = 183 cookies.
Calculation of total number of boxesThe total number of cookies the bakery makes in a day =
1,650 cookies.
The number of cookies found in big box = 24 cookies
The number of cookies found in small box = 3 cookies
To find the number of small boxes that was fill would be to share 1,650 cookies in the ratio of 24 : 3
The total amount of cookies each box can hold = 24+3=27
Divide the amount by the total quantity of cookies=
1,650/27 = 61 cookies
Each number of the boxes should be multiplied by one part ; small boxes × 61 cookies
= 3 × 61
= 183 cookies.
Therefore, the number of small boxes the bakery fills in a day = 183 cookies.

A swimming pool is in the shape of a rectangular prism. The pool is 30 feet long, 16 feet wide, and 6 feet deep. James stretched a hose straight from a top corner of the pool to the bottom corner farthest away. What is the length of the hose from the top corner to the bottom corner farthest away?
Answer:
About 34.5 which you can round to 35
Step-by-step explanation:
First you find the hypotenuse of 30 and 16 which is 34
Then the hypotenuse of 34 and 6 which is about 34.5
The length of the hose from the top corner to the bottom corner farthest away will be 34.5 feet
What is a Rectangular Prism?A rectangular prism is a 3-D figure, which has 6 faces, 8 vertices and 12 edges. All of the faces will be in rectangular shape.
Rectangular prism has three dimensions, namely, length, width and height.
Length of the swimming pool = 30 feet
Width of the swimming pool = 16 feet
Height of the swimming pool = 6 feet
We have to find the length of the hose from the top corner to the bottom corner farthest away.
For that first we have to find the length of the hypotenuse of the triangle with base = 30 feet and altitude = 16 feet
= √(30² + 16²)
= 34 feet
Now, we have to find the hypotenuse of the triangle with base = 34 feet and altitude = 6 feet.
= √(34² + 6²)
= 34.5 feet
Hence the length of the hose from the top corner to the bottom corner farthest away is 34.5 feet.

Step-by-step explanation:
Use the table to write a linear function that relates y to x .
x −2 −1 0 1
y 8 5 2 −1
The linear function is y= ?
Answer:
The linear function is [tex]y = -3x + 2[/tex]
Step-by-step explanation:
A linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(the value of y when x = 0).
In the table, we have that when x = 0, y = 2
This means that [tex]b = 2[/tex]. So
[tex]y = mx + 2[/tex]
Finding the slope:
We take two points, and the slope is given by the change in y divided by the change in x.
Points (0,2) and (1,-1)
Change in y: -1 - 2 = -3
Change in x: 1 - 0 = 1
Slope: [tex]m = \frac{-3}{1} = -3[/tex]
So
[tex]y = -3x + 2[/tex]

Given that;
The expression is,
[-1, -2, 4, 8] + x = [-5,- 1, 2, 1]
Now, We can simplify as;
x = [- 5, - 1, 2, 1] - [ - 1, - 2, 4, 8]
x = [- 4, 1, - 2, - 7]
Thus, The value of x in expression is,
