Answer:
Step-by-step explanation:
Means=15
Median=15
5,8,12,14,15,15,15,17
cross them out until you get to the middle and the middle will be median when there's add them together then divide by 2
14+15=29
29÷2=14.5
Answer:
1st picture: (0,4)
The lines intersect at point (0,4).
2nd picture: Graph D
2x ≥ y - 1
2x - 5y ≤ 10
Set these inequalities up in standard form.
y ≤ 2x + 1
-5y ≤ 10 - 2x → y ≥ -2 + 2/5x → y ≥ 2/5x - 2
When you divide by a negative number, you switch the inequality sign.
Now you have:
y ≤ 2x + 1
y ≥ 2/5x - 2
Looking at the graphs, you first want to find the lines that intersect the y-axis at (0, 1) and (0, -2).
In this case, it is all of them.
Next, you would look at the shaded regions.
The first inequality says the values are less than or equal to. So you look for a shaded region below a line. The second inequality says the values are greater than or equal to. So you look for a shaded region above a line.
That would mean Graph B or D.
Then you look at the specific lines. You can see that the lower line is y ≥ 2/5x - 2. You need a shaded region above this line. You can see the above line is y ≤ 2x + 1. You need a shaded region below this line. That is Graph D.
To solve this problem, you need to do it in this order: PEMDAS
(Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
2 × 4 ÷ 6(8 × 3) - 6 = Y First simplify inside the ( ), and multiply 8 by 3
2 × 4 ÷ 6(24) - 6 = Y Now multiply 6 and 24
2 × 4 ÷ 144 - 6 = Y Multiply 2 and 4
8 ÷ 144 - 6 = Y Divide 8 and 144
18 - 6 = Y Subtract 18 and 6
12 = Y
About less than 3 inches :)
