Answer:
139
Step-by-step explanation:
Just took the quiz on K-12
Hope its not to late
The prediction for the number of passwords in which the first character is a number is 139. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
The answer is 192 passwords. This is because there is an equal probability of each character (0-9 and uppercase letters) being chosen as the first character of a password.
Since there are 10 different numbers (0-9) and 26 uppercase letters, the probability of the first character being a number is 10/36
If 500 passwords are generated, the expected number of passwords in which the first character is a number is 500 ×10/36
= 5000/36
= 138.88
≈ 139
Therefore, option B is the correct answer.

10 | 30 | 50 | 70 | 90
1 1 3 2 1
10 | 30 | 50 | 70 | 90
Answer: Answer:
There is moderate level of overlap between the two data sets.
Step-by-step explanation:
Overlap of data sets.
Overlap measures the degree of duplication that exists within data sets.
It is an indicator of the degree to which data are identical.
We are given two data sets in the question.
We have to find the amount of overlap in data set 1 and in data set 2.
There are 8 data points in data set 1 as shown in the image.
There are 8 data points in the data set 2 as shown in the image.
Out of the 8 data points for both data set 1 and data set 2, 5 data points overlap each other on 6, 7, 8 and 9.
Thus, we could say there is moderate level of overlap between the two data sets.

Answer:
7.2 | 6.2 | 2.2 | -2.8 | -3.8 | -8.8
0.2
Step-by-step explanation:
Step 1) Find the mean
How to find it?
Add all the numbers listed above and divide by the number of numbers in the set (6)
This mean you should get 67/6=11.2
Step 2) Find the distance from the mean.
How do I do this?
Since you are trying to find the difference you will use the equation 11.2-(number)
Example) 11.2-4=7.2
This will give you the answers for the second half of the table.
Step 3) Find the mean of those distances to find the mean absolute deviation
How do I do this?
Add all the numbers on the second half of the table and then divide by 6. This will give you your mean absolute deviation.
I hope this helps! :D

Answer the QUESTIONS below.
Find the area of the composite figure.
602 square centimeters
374 square centimeters
488 square centimeters
469 square centimeters
Answer:
Option C, 488 square centimeters
Step-by-step explanation:
Step 1: Determine the area of the rectangle
[tex]A = l * w[/tex]
[tex]A = 22\ cm * 17\ cm[/tex]
[tex]A = 374\ cm^2[/tex]
Step 2: Determine the area of the triangle
[tex]A=\frac{h*b}{2}[/tex]
[tex]A=\frac{19\ cm * (22\ cm-10\ cm)}{2}[/tex]
[tex]A=\frac{19\ cm * (12\ cm)}{2}[/tex]
[tex]A=\frac{228\ cm^2}{2}[/tex]
[tex]A=114\ cm^2[/tex]
Step 3: Determine the total area
[tex]A_{total} = 374\ cm^2 + 114\ cm^2[/tex]
[tex]A_{total} =488\ cm^2[/tex]
Answer: Option C, 488 square centimeters

Which two expressions are equivalent?
F
Step-by-step explanation:Each of these answer choices represents a different property of equality; however, only answer choice F uses the properties of equality (PoEs) correctly.
Answer Choice F
The first answer choice shows the distributive property. This property states that multiplying a number by a factor in parentheses is the same as multiplying the number outside the parentheses by each of the terms within the parentheses.
For example, [tex]5(x-y)=5x-5y[/tex].Answer Choice G
This answer choice attempts to show the associative property. The associative property states that when doing addition, the placement of the parentheses does not matter. However, this answer uses addition and multiplication, so the associative property does not apply.
Answer Choice H
This answer choice tries to show the commutative property. The commutative property states that addition and multiplication can be done in andy order. However, this only applies to addition and multiplication. So, it cannot be used for division.
Answer Choice J
This answer choice tries to use the associative property similar to the second answer. However, as I stated earlier, this property only works for addition. So, the use of multiplication in the expression makes it so they are not equal.
Answer:
F is your answer
Step-by-step explanation:
Answer Choice F
The first answer choice shows the distributive property. This property states that multiplying a number by a factor in parentheses is the same as multiplying the number outside the parentheses by each of the terms within the parentheses.

The profit (p) a baker earned, in dollars, is proportional to the number of muffins (m) sold. this equation represents this relationship.
P = 0.75m
enter the profit earned for each muffin sold.
Answer:
The profit is $0.75 per muffin.
Step-by-step explanation:
If P = .75m, then if m is 0, then P is zero (if the baker sells no muffins, they make no money)
If m = 1 (sold 1 muffin)
then P = .75, they made 75cents.
"for each muffin sold" means for 1 muffin.
