Use the frequency histogram to complete the following parts. (a) Determine the number of classes. (b) Estimate the greatest and least frequencies. (c) Determine the class width. (d) Describe any patterns with the data.
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question in the attachment file.
In choice (a):
7 classes are available because there are 7 bars of the histogram.
In choice (b):
Its lowest frequency is $32,000 for employee wages
There are around 20 of them.
It is around 20 the least frequency
$ 47,000 was its largest frequency for employees.
There are another 300
The highest frequency is about 300
In choice (c):
Its width of the class is 5, its difference between all the centers, that can also be seen.
In choice (d):
They get below in when we see frequencies per each class.
[tex]\text{Class Midpoint} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Frequency}\\\\32 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 20\\\\37 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 180\\\\42 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 270\\\\47 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 300\\\\52 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 250\\\\57 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 70\\\\62 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 60\\\\[/tex]
They can see in this certain half of workers' wages are between 40,000 and 49,000 dollars.

Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. What does the ratio 5 : 13 represent in this situation? Use a model to show your work. Explain your reasoning.
Answer:
m
Step-by-step explanation:
The ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias in Myra's flower bed.
A ratio shows us the number of times a number contains another number.
Given that Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. Therefore, the ratio of number of Lilies to the number of tulips and zinnias are,
Ratio = Number of Lilies : Number of tulips and zinnias
Ratio = 5 : (7+6)
Ratio = 5 : 13
Hence, the ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias.

Which equation represents the graphed function?
O y = 4x - 2
O y = -4x - 2
Oy = -x-2
O y=-x-2
9514 1404 393
Answer:
y = 1/4x -2
Step-by-step explanation:
The line rises one unit from -2 to -1 as x changes from 0 to 4. The slope is ...
m = rise/run = 1/4
The y-intercept (b) is where the line crosses the y-axis, at y = -2.
The equation in slope-intercept form is ...
y = mx + b
y = 1/4x -2
The equation for the linear function is
y= BLANK1 x + BLANK 2
What are the blanks?
Answer:
Answer:y=x divided by 3 times 5.
Step-by-step explanation:
if you divide x for example 6 by 3, you will get 2 then multiply it by 5, you will get 10, which is y.
Given the ordered pair (12,5), find cot θ
Answer:
12 left and 5 down
Step-by-step
On the X Axis, you need to move 12 points left.
On the Y Axis, you need to move 5 points down.
This will bring you to (0, 0)
Kelly uses point p to represent the sum of 3.6 +(-2.4) on the number line.
3.6 + (-2.4) = p
Kelly says that point pis plotted to the right of both 3.6 and -2.4 on the number line because addition means you should move right on the
number line.
• Explain why Kelly's reasoning is incorrect.
• Explain how the location of p on the number line is related to the locations of 3.6 and -2,4 on the number line.
Determine the value of point p.
Enter your explanations and your answer in the box provided.
Answer:
Kelly is incorrect because she added the two numbers on the number line that made no since.
If Kelly had worked through the problem
P would have equaled 1.2
3.6+(-2.4) = 1.2 which is what p equals
The value of P is 1.2
The value of p is 1.2.
What is an absolute value?Absolute value of a number is the distance value from zero without considering sign of a number. It is also represented as |x|, where x is any number.
Given that the expression, 3.6 + (-2.4) = p
To find the value of p,
3.6 + (-2.4) = p
p = 1.2
Relation of p in number line with -2.4 and 3.6 ;
p = 1.2 in the number line is right side of -2.4 and left side of 3.6.
Whenever we add the positive numbers we get the sum of the number in the right side of both the positive number.
And whenever we add the negative numbers we get the sum of the number in left side of both of the negative number.
And when we add the positive and negative number then if
1) positive number > absolute value of negative number then sum of the numbers will be in the middle of the both number.
And 2) if positive number < absolute value of negative number then the sum of the numbers will be in the middle of both of the number.
Therefore the value of p is 1.2.

Answer:
-1 and 2Step-by-step explanation:
Let the numbers be x and y
Three times the first number minus two times the second number equals -7:
3x - 2y = -7The second number equals one less than negative three times the first number:
y = -3x - 1Substitute y in the first equation and solve for x:
3x - 2(-3x - 1) = -73x + 6x + 2 = -79x = -9x = -1Find the value of y:
y = -3(-1) - 1 y = 3 - 1y = 2The numbers are -1 and 2

Identify which of the following is most appropriate: discrete random variable, continuous random variable, or not a random variable.
a. Exact weights of the next 100 babies born in the United States
b. Responses to the survey question "Which political party do you prefer?"
c. Numbers of spins of roulette wheels required to get the number 7
d. Exact foot lengths of humans
e. Shoe sizes (such as 8 or 8½) of humans.
Answer:
A.) Continuous random variable ;Not a random variable ; Discrete random Variable ; Continuous random variable ; discrete random variable
Step-by-step explanation:
Identify which is most appropriate category for the sample data given below :
a. Exact weights of the next 100 babies born in the United States
This is a continuous random varibake as it could take up any value including decimals in other to specify the exact weight of an individual.
b. Responses to the survey question "Which political party do you prefer?"
Not a random variable as the outcome to this question isn't numerical.
c. Numbers of spins of roulette wheels required to get the number 7
This is a discrete random variable as the number of roulette spins would be a whole number within a specified fic range.
d. Exact foot lengths of humans
Continuous random variable
The exact foot length of human would vary greatly and in a bid to give an exact value, foot length will most definitely take up decimal values
e. Shoe sizes (such as 8 or 8½) of humans.
This is also a discrete random variable as shoe sizes are restricted to a specific range. Even with the inclusion of 1/2 in the measurement, there are no values inbetween (8 and 8 1/2) which will be the same for the remaining value range.

Answer:
C

Tina ate 21 starbursts. If she ate 35% of the package of Starbursts, how many Starbursts are in the package?
Show your work
Answer:
60 starbursts
Step-by-step explanation:
We can set up an equation to find the answer. 21/x=0.35/1 because we're trying to find how many starbursts make up 100% of the package. So then to solve, we take 21x1 and then divide that by 0.35. From this we find that x=60.
