1. Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.
3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4. Test the residuals of two other points to determine how well the line of best fit models the data.

Rhombus

Step-by-step explanation:

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles. Kites have two pairs of adjacent sides that are equal.

Answer:

A rhombus

Step-by-step explanation:

A rhombus has four congruent sides, and does not necessarily have to have right angles. (A square is considered a rhombus and has four right angles, so that is the only exception). So, your answer would be rhombus!

**The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room are in the ratio 4 :3: 2. The combined area of these three rooms is 189 square feet. What is the area of each room?

Answers

Answer:4 : 3 : 2

x - area unit

area of the kitchen = 4x

area of the playroom = 3x

area of the dinning room = 2x

The combined area of these three rooms is 189 ft².

Therefore we have the equation

4x + 3x + 2x = 189

9x = 189    |:9

x = 21 ft²

area of the kitchen = 4x = 4(21) = 84 ft²

area of the playroom = 3x = 3(21) = 63 ft²

area of the dinning room = 2x = 2(21) = 42 ft²

Step-by-step explanation:

Answer:4 : 3 : 2

x - area unit

area of the kitchen = 4x

area of the playroom = 3x

 

area of the dinning room = 2x

 

The combined area of these three rooms is 189 ft².

Therefore we have the equation

4x + 3x + 2x = 189

9x = 189    |:9

x = 21 ft²

area of the kitchen = 4x = 4(21) = 84 ft²

area of the playroom = 3x = 3(21) = 63 ft²

area of the dinning room = 2x = 2(21) = 42 ft²

At Chewie's Porg Palace, one family meal comes with 3 side dishes and 10 pieces of porg.

Complete the double number line diagram to show the number of side dishes and pieces of porg in 1, 2, 3, and 4 family meals.

Answers

Answer:

Side Dishes: 3, 6, 9, 12

Porg: 10, 20, 30, 40

Step-by-step explanation:

For the Side Dishes number line, multiply 3 x 1 family meal = 3, 3 x 2 family meals = 6, 3 x 3 family meals = 9, and 3 x 4 family meals = 12

For the Pieces of Porg, multiply 10 x 1 family meal = 10, 10 x 2 family meals = 20, 10 x 3 family meals = 30, 10 x 4 family meals = 40

2. If you know the value of t, would the evaluated expression be different if you added the known value of t and 5 and then multiplied by 3.6? Explain.

Answers

Answer:

Step-by-step explanation:

1) The expanded form of 3.6(t + 5) is 3.6t + 18.

The expression 3.6(t + 5) is equivalent to 3.6t + 18 and yes, the given value will be different for different values of [t].

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the expression as -

3.6(t + 5)

We have the following expression -

3.6(t + 5)

3.6t + (3.6 x 5)

3.6t + 18

YES, the given value will be different for different values of [t].

Therefore, the expression 3.6(t + 5) is equivalent to 3.6t + 18 and yes, the given value will be different for different values of [t].

convert 2 1/2 hours into minutes to be easier to work with

15 / 150 = 10 minutes

every 10 minutes he pots a plan.

there are 210 minutes in 3 1/2 hours

210 / 10 = 21

Given the equation y = 2 x - 8, what is the slope and the y -intercept?

Answers

Answer:

m=2 and b=-8

Step-by-step explanation:

This equation is organized in slope-intercept form, y=mx+b. In this form, m is the slope and b is the y-intercept.

When given the equation, y=2x-8, we can see that 2 is in the place of m and -8 is in the place of b. The reason the y-intercept isn't 8 is that y=2x-8 can be written as y=2x+(-8) since y=mx+b involves addition. Therefore, the slope is 2 and the y-intercept is -8.

m=2 and b=-8
