The equation most closely models the line of best fit for the scatter plot is y = 2.5x

A line is the defines as the minimum distance between two points. The equation of a line is given in the form y =mx + b

where:

In order to determine the required equation, we can use the coordinate  (3, 5000) and (9, 20000)

Determine the slope

Slope = 20000-5000/9-3
Slope = 15000/6 = 2500

Determine the y-intercept

5000 = 2500(3) + b

b = 5000 - 7500
b = -2500

Determine the equation

y = 2.5x - 2.5

Therefore the equation most closely models the line of best fit for the scatter plot is y = 2.5x

Using the Mean Absolute Deviation(MAD) concept, it is found that:

a) The Jumping Jackrabbits have a MAD of 3.6 and the Leaping Lizards of 6.8.

b) The MAD is lower for the Jumping Jackrabbits then for the Leaping Lizards, hence their scores are more consistent.

Item a:

For the Jumping Jackrabbits, the mean and MAD are given by:

M = (70 + 65 + 72 + 80 + 73)/5 = 72

MAD = (|70 - 72| + |65 - 72| + |72 - 72| + |80 - 72| + |73 - 72|)/5 = 3.6.

For the Leaping Lizards, the mean and the MAD are given by:

M = (61 + 47 + 70 + 63 + 54)/5 = 59

MAD = (|61 - 59| + |47 - 59| + |70 - 59| + |63 - 59| + |54 - 59|)/5 = 6.8.

The Jumping Jackrabbits have a MAD of 3.6 and the Leaping Lizards of 6.8.

Item b:

The MAD is lower for the Jumping Jackrabbits then for the Leaping Lizards, hence their scores are more consistent.

The equation that the given graph of the system of equations solves is: 1/3x + 1 = 2x - 4.

Where m is the slope and b is the y-intercept, the equation of a line in slope-intercept form is expressed as y = mx + b.

Equation of the Blue Line:

Slope (m) = change in y / change in x = 2/1 = 2

y-intercept (b) = -4.

Equation: y = 2x - 4

Equation of the Red Line:

Slope (m) = change in y / change in x = 1/3

y-intercept (b) = 1

Equation: y = 1/3x + 1

The equation that the graph of the systems of equations solve would be: 1/3x + 1 = 2x - 4.

Answer:

( - 1, - 5)

Step-by-step explanation:

Elimination Method:

Multiply the second equation by -1, then add the equations together.

(3x−4y=17)

−1(7x−4y=13)

Becomes:

3x−4y=17

−7x+4y=−13

Add these equations to eliminate y:

−4x=4

Then solve−4x=4for x:

−4x=4

-4x / -4 = 4/-4 (Divide both sides by -4)

x= −1

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

3x−4y=17

Substitute−1forxin3x−4y=17:

(3)(−1)−4y=17

−4y−3=17(Simplify both sides of the equation)

−4y−3+3=17+3(Add 3 to both sides)

−4y=20

-4y/ -4 = 20/ -4 (Divide both sides by -4)

y=−5

The estimate that 2.8 million square feet of the building is used for office space is not reasonable

From the plan, the width of the building is:

Width = 230 feet

The building has a circular area, and it has four floors

So, the estimate of the building area is:

Area= 4πR²

So, we have:

Area= 4 * 3.14 * 230²

Evaluate

Area= 664424

The above value cannot be approximated to 2.8 million

Hence, the estimate used for office space is not reasonable

The probability of choosing a boy from both classrooms is 19/20, the probability of choosing a girl from Classroom 101 and a boy from Classroom 103 is 39/100, and the probability of choosing a boy from Classroom 101 and a girl from Classroom 103 is 7/50

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total number of students in classroom 101 = 13+7 = 20

Total number of students in classroom 103 = 8+12 = 20

The probability of choosing a boy from both classrooms:

= 19/20

Choosing a girl from Classroom 101 and a boy from Classroom 103:

Since both are independent event.

Probability of choosing a girl from Classroom 101 = 13/20

Probability of choosing a boy from Classroom 103 = 12/20

The probability of choosing a girl from Classroom 101 and a boy from Classroom 103:

= (13/20)(12/20)

= 156/400

= 39/100

Similarly, the probability of Choosing a boy from Classroom 101 and a girl from Classroom 103:

= (7/20)(8/20)

= 56/400

= 7/50

Similarly, we can find remaining probability.

Thus, the probability of choosing a boy from both classrooms is 19/20, the probability of choosing a girl from Classroom 101 and a boy from Classroom 103 is 39/100, and the probability of choosing a boy from Classroom 101 and a girl from Classroom 103 is 7/50

Hope this helps. :-)

The age of Marissa and her younger brother.

We know that the older brother's age is 18 and he is twice older than the younger brother.

Let the unknown be "x"

[tex] x=\frac{18}{2} [/tex]

[tex]\large\boxed{\sf{x=9 \: years}}[/tex]

Now, we know that the younger brother's age is 9 and Marissa is 3 years older than him.

Let the unknown be "x"

[tex]x=9 + 3[/tex]

[tex]\large\boxed{\sf{x=12 \: years}}[/tex]

Therefore, Marissa is 12 and her younger brother is 9

Answer:

Marissa's age = 12

Younger brother's age = 9

Step-by-step explanation:

Let age of Marissa be x, and her younger brother's y.

Equations formed :

Finding age of younger brother using Equation 2 :

⇒ 2y = 18

⇒ 2y/2 = 18/2

⇒ y = 9 years old

Substituting y in Equation 1 :

⇒ x = y + 3

⇒ x = 9 + 3

⇒ x = 12 years old

Marissa's age = 12

Younger brother's age = 9
