If order matters, then there are 12 ways to do this

If order does not matter, then there are 6 ways to do this

===========================================

We have 4 choices for the first slot and 3 choices for the next (we can't reuse a letter) so that's where 4*3 = 12 comes from

If order doesn't matter, then something like AB is the same as BA. So we are doubly counting each possible combo. To fix this, we divide by 2: 12/2 = 6

To be more formal, you can use nPr and nCr to get 12 and 6 respectively (use n = 4 and r = 2)

What is the rate of change and initial value for the linear relation that includes the points shown in the table? x; 1,3,5,7
BARSIC [14]

Answer:

The rate of change is -5

The initial value is 25

Step-by-step explanation:

Since, this is a linear relation

so, we can select any two points and find equation of line

points are (1,20) and (3,10)

so,

x_1=1,y_1=20

x_2=3,y_2=10

now, we can find slope

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{10-20}{3-1}

m=-5

now, we can use point slope form of line

y-y_1=m(x-x_1)

now, we can plug values

y-20=-5(x-1)

now, we can solve for y

y=-5x+25

we know that

slope is the rate of change

So, the rate of change is -5

For finding initial value , we can plug x=0 and find y

y=-5\times 0+25

y=25

So, initial value is 25

Some teachers compared how many years they have been teaching.
Alex_Xolod [135]

Answer:

6

Step-by-step explanation:

The range of a data set is the numbers covered by the data. This means that the range is the difference between the minimum and maximum. The minimum is the smallest point, 2, and the maximum is the largest point, 8. Therefore, since 8-2=6, 6 must be the range.
