The value 8 is significantly different from the other four values.  Thus, the median would be the most appropr. measure of the center of this data distribution.  Rearranging the data in ascending order:

8, 29, 31, 32, 33

The median is the middle value; it is 31.

Answer:

see explanation. (I did this exact assignment this morning, and this is very similar to what I submitted)

Step-by-step explanation:

The contrapositive of a conditional is the same as the converse of the inverse of the conditional.

The best way to prove/support this statement is to create an example. You should start by creating a conditional; you can then form the conditional's converse, inverse, and contrapositive. Here is an example:

Conditional: If C, then D. (starting statement)

Converse: If D, then C. (conditional reversed)

Inverse: If not C, then not D. (opposite of the conditional)

Contrapositive: If not D, then not C. (reversed opposite of the conditional)

Based on the information from the example you gave, you can conclude:

The converse of the inverse: If not D, then not C. (reversed opposite of the conditional)

Because: The converse is the conditional reversed (If D, then C). The inverse of the converse, in this case, would then make it the opposite (If not D, then not C).

I have not yet received a grade on this assignment, but I know the information is correct; the amount of explanation you need to give really depends on how your teacher grades. Personally, I just submitted an example (similar to the one above) that was color-coded to help show the different parts of each statement.

I hope this helps! :)

Solve the system of equations using the substitution method.
sasho [114]
4x+5(3x+9)=7
4x+15x+45=7
19x=7-45
19x = -38
\frac{19x}{19}  =  \frac{ - 38}{19}
x= -2

y=3(-2)+9
y=-6+9
y= 3

Use the distributive property to solve the equation 28-(3x+4)=2(x+6)+x. Show your work.
Gre4nikov [31]

Answer:

x=2

Step-by-step explanation:

28−(3x+4)=2(x+6)+x

We need to use the distributive property for the right side.

28−3x−4=(2)(x)+(2)(6)+x)

28−3x−4=2x+2+x

−3x+24=3x+12

From here we need to subtract 3x from both side.

−3x+24−3x=3x+12−3x

6x+24=12

Transfer +24 on the right side.

6x=12−24

6x=−12

Finally, divide both sides by −6

6x/-6 = -12/-6

x=2

Solve the system of equations: y=2x-5. y=x^2-5
VikaD [51]

Answer:

(0, -5) and (2, -1)

Step-by-step explanation:

Since both equations have already been solved for y, the substitution method is the easiest approach here.  Set the two equations equal to each other:

y = 2x - 5 = x^2 - 5 = y

Focusing on the variable x only, we get 2x - 5 = x^2 - 5.

Adding 5 to both sides results in 2x = x^2.

Factoring this result, we get x(2 - x)  = 0, whose solutions are

x = 0 and x = 2.

Now find the corresponding y-values:

If x = 0, then y = 2(0) -5, or y = -5;

If x = 2, then y = 2(2) - 5, or y = -1

Writing the solutions as coordinate pairs:  (0, -5) and (2, -1)
