The Line Plots Below Show The Number Of Students In Each Of Andres And Mandys Classes At School. Approximately

Answers

Answer 1

Answer:

the answer is 5.0

Step-by-step explanation:

Answer 2

The difference between the means of the Andre's and Mandy's classes are 1.42. [tex]X_{AM}=1.42X_{MM}[/tex]

What is mean?

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

From the data given we will calculate the mean of andres's class students and mandy's class students.

For Andre's

[tex]X_{AM}=\dfrac{20+21+22+23+25}{5}=22.5[/tex]

For Mandy

[tex]X_{MM}=\dfrac{14+15+15+16+19}{5}=15.8[/tex]

So here we will compare the means

[tex]\dfrac{X_{AM}}{X_{MM}}=\dfrac{22.5}{15.8}=1.42[/tex]

[tex]X_{AM}=1.42X_{MM}[/tex]

how is solving inequalities with addition and subtraction similar to and different from solving equations with addition and subtraction?

Answers

That technique for solving equations is: Whatever you do to one side of the equation, you have to do to the other side to preserve the equality The technique for solving inequalities is: Whatever you do to one side of the inequality, you have to do to the other side to preserve the inequality. the techniques are the same. The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!

He’ll need 16 trapezoids for 8 birdhouse
For 3 birdhouses, he’ll need 12 rectangles
If koda uses 4 squares, he’ll need 8 triangles

Answer:

1.) To make 8 birdhouses, Koda will need 16 trapezoids. (16)

2.) For Koda to make 3 birdhouses, he will need 12 rectangles. (3)

3.) If Koda uses 4 squares to make birdhouses, he will use 8 triangles. (8)

Step-by-step explanation:

1.) To make 8 birdhouses, Koda will need 16 trapezoids.

Explanation: The instructions showed how many trapezoids are needed to make ONE birdhouse, so you just multiply 8 by 2 which is 16.

2.) For Koda to make 3 birdhouses, he will need 12 rectangles.

Explantion: Theinstructions showed how many rectangles are needed to make ONE birdhouse, and the question ask for how many birdhouses he can make with 12 rectangles. So you need to divide 12 by 4 (12÷4) which gives you 3. 12÷4=3.

3.) If Koda uses 4 squares to make birdhouses, he will use 8 triangles.

Explantion: The instructions howed that he’ll need TWO triangles to make ONE birdhouse And the question asks for 4 squares to make birdhouse and how many triangles he’ll use. So you multiply 4x2 and got 8.

The third graph is correct

Step-by-step explanation:

Hiiii,

Since the sign is < and doesn't have a line underneath (or equal to), it means we have an open circle. We also know that the line has to go to the left because all the values that go to the left make the inequality true. If they go to the right, it won't be true because the value will be greater than 21 and we need it to be less than 21.
