Answer:

Alisha might have not taken respective input values with the output values and the correct slope is 3.

Step-by-step explanation:

The general form of a linear relationship is given by the equation

y = mx+b

Here m is the rate of change of the linear relationship which is calculated as:

m = \frac{change\ in\ y}{change\ in\ x}

Change in y is given by the difference of two outputs and x is given by difference of two inputs

So taking the set of outputs and inputs

(1,2) and (2,5)

m = \frac{5-2}{2-1}\\m = \frac{3}{1}\\m = 3

Alisha might have not taken respective input values with the output values and the correct slope is 3.

In this line of circles, the ratio of red circles to blue circles is 1:3 How many more circles would need to be added to make th
zaharov [31]

Answer:

The number of red circles to be added would be equal to 8 times the original amount of red circles

Step-by-step explanation:

Let

x ----> the number of red circles

y ----> the number of blue circles

Originally

\frac{x}{y}=\frac{1}{3}

y=3x ----> equation A

How many more circles would need to be added to make the ratio of red to blue 3:1

Let

n ----> the  number of additional red circles

\frac{x+n}{y}=\frac{3}{1} ----> equation B

substitute equation A in equation B

\frac{x+n}{3x}=\frac{3}{1}

solve for n

x+n=9x\\n=9x-x\\n=8x

therefore

The number of red circles to be added would be equal to 8 times the original amount of red circles

Mean: 65

MAD: 6.4

2.

Mean: 60.5

MAD: 6.4

3. The diference of the means are 4.5

I’m sorry, I do not understand the last one.

Step-by-step explanation:

The mean is the average, add all of the values and divide the result by the number of values. The MAD is the mean absolute deviation. You find it by taking the distance between the values and the mean. You then add them together and divide it by the mean. I really hope this helps you!
