PLZ HELP. Rima wants to learn more about the heights of the students at Spring Valley Middle School. The school teaches students in grades 6 through 8. Each subject is taught by a different teacher, so students change classrooms every period. Students don’t have a class every period, but every student has a homeroom class. Consider five samples from this population, then answer the questions that follow. Sample A: Survey four random students in each of Rima's classes. Sample B: Survey two random students from each homeroom class. Sample C: Survey three random girls from every third-period class. Sample D: Survey every sixth person in the student directory. Sample E: Survey every third person in the band directory. Part A Is sample A a random sample? Why or why not?

Answers

Answer:

PART A: Sample A is not a random sample. In a random sample, all members of the population have an equal chance of being selected. Sample A has students from Rima’s classes, but no students from other classes. Students from the other two grades in the school won’t be represented.

PART B: Sample B is a random sample. Every student, or every member of the population, has a homeroom class. All of them have an equal chance of being selected in the sample.

PART C: Sample C is not a random sample because the sample excludes boys. The sample should include both girls and boys to represent the entire student population.

PART D:  Sample D is a random sample. All students in all grades are featured in the student directory, so all of them have an equal chance of being picked for the sample.

PART E: Sample E is not a random sample because it consists of only the students in the band and excludes all other students from the sample. Because not every student is in the band, this is not a fair representation of the entire student body.

please give me brainlist thank you and have a good day :)

Answer:

PART A: Sample A is not a random sample.

PART B: Sample B is a random sample.

PART C: Sample C is not a random sample.

PART D:  Sample D is a random sample.

PART E: Sample E is not a random sample.

Answers

Okay so for this you need to find the unit rate.

To find the unit rate:
Divide 5.25 feet by 3 feet, and I got 1.75, so the unit rate would be 1.75 feet(Jorge’s height)/1 foot of shadow. A shorter version of this would be 1.75/1

Then, now that you know the unit rate, or how many feet in height for every one foot of shadow, you multiply 1.75 by the length of the shadow (23 feet). For this I got 40.25.

40.25 is the height of the flag pole :)

Answer:

40.25 feet tall

Step-by-step explanation:

There is a small triangle made by the boy and the three feet of shadow. This triangle when scaled up will be the same as the flag and the full shadow.

To do this you need to find how much to multiply 3 by to get 23.

First you do 23/3 which will give you 7.6 repeating. or 7.6666666666... (same thing)

If you then multiply that number by the boy's height 5.25 you will get the answer 40.25.

This is because the triangle the flag creates is 7.666... times larger than the triangle the boy creates.

3 Choose the two triangles that are similar. Explain how
you identified them.

Module 06: Project Option 1
Instructions:

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.


Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.


Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.


2. Translate the new algebraic expression you created in Question 1 to a verbal expression.


Part 2: Writing Equivalent Expressions
3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.


a. Use either the commutative property or combine like terms to create an equivalent expression.


b. Use the distributive property to create an equivalent expression.


4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.



Part 3: Finish the Story
5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?



6. Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

The answer is subtract two from both sides. Explanation: because it males the equation even and easier to solve.

Answer:

[tex] \underline{ \underline{ \boxed{ \text{Subtract \: 2 \: from \: both \: sides}}}}[/tex]

Step-by-step explanation:

Since we want constants only on the right hand side , we have to remove 2 which is on the left hand side. The opposite of +2 is -2 and whatever we do to one side , we must do to the other side. So, The first step that would be used to solve the equation should be Subtract 2 from both sides.

What inverse operation would you perform on both sides to solve this equation?
4-c=26 and solve it pls

Answers

Answer:

c=-24

Step-by-step explanation:

You should perform the inverse of addition and multiplication

The inverse of addition is subtraction so we subtract 4 on both sides:

4-4-c=26-4

Which will be

-c=24

Divide by -1 since the inverse of multiplication is division

-c/-1=24/-1

So the answer will be:

c=-24

The answer to this equation should be c=-24 I Hope this helps
