Order Data (least to greatest): 35,40,42,46,47,52

Mean: 43.66

MAD:4.66

Could not figure out Mean of Differences sorry!

Step-by-step explanation:

To find the mean you add all of the numbers and divide by the amount.

To find MAD find the sum of the data values, and divide the sum by the number of data values.

≥≤ are used when the number is less/greater or equal than some thing.

>< are used when a number is strictly less/greater than some thing.

1) a number x is less than 0 or at least 3

A number x is less than 0 is written as: x < 0.

x is at least 3 is written as: x ≥ 3.

Then we can write the statement as:

x < 0  ∨ x ≥ 3.

where ∨ means "or"

2) a number x is less than or equal to 4 and greater than -1

x less than or equal to 4 is written as: x ≤ 4

x is greater than -1 is written as: x > - 1.

We can write the statement as:

-1 < x ≤ 4

3) a number x is less than 8 and greater than or equal to 5

x is less than 8 is written as: x < 8

x is greater than or equal to 5 is written as: x ≥ 5.

Then the statement can be written as:

5 ≤ x < 8,

The answer is D
The first thing you have to do is substitute so
It would be
-3|-12-8|+1.5
-12-8=-20
-20•-3=-60
-60+1.5=-58.5

The line of symmetry is like vertex but without k value.

From (h, k) which is vertex. h is basically a line of symmetry.

Therefore if vertex for the graph is (-2,-5)

The line of symmetry would be x=-2

So the answer is B.

B

Step-by-step explanation:

We have the compound inequality:

5x+7\leq-3 \text{ or } 3x-4\geq 11

Since this is an “OR” inequality, we can solve each inequality individually. So:

1)

We have:

5x+7\leq-3

Subtract 7 from both sides:

5x\leq -10

Divide both sides by 5:

x\leq-2

So, the first solution is above.

2)

We have:

3x-4\geq 11

Add 4 to both sides:

3x\geq15

Divide both side by 3:

x\geq5

Our second solution is above.

Therefore, our solution is:

x\leq -2 \text{ or } x\geq5

Since our original inequality is “OR,” our solution set remains an “OR.”

Hence, our answer is B.
