Answer:
Properties of a normal distribution
The mean, mode and median are all equal.
The curve is symmetric at the center (i.e. around the mean, μ).
Exactly half of the values are to the left of center and exactly half the values are to the right.
The total area under the curve is 1.
Step-by-step explanation:
If QR is a median, then:
We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:
<h3>Answer: A. 6</h3>
<span>39 & 16.5 = -22.5
30 & 12.4 = -17.6
28 & 10.4 = -17.6
19 & 10.3 = -8.7
23 & 11.2 = -11.8
if the values are y values you will subtract them from each other to get the numerical value and because they all go from a larger number to a smaller number the rate is a negative. if they were from a smaller value to a larger value teh rates of change would be positive.

Answer:
5.5 yards.
Step-by-step explanation:
We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.
First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:
We know that 1 yard equal to 36 inches. To convert 198 inches into yards, we will divide 198 by 36 as:
Therefore, the total amount of ribbon that Mimi needs is 5.5 yards.
