Answer:
Median = 70
Range = 10
Step-by-step explanation:
The median of a set of data is the middlemost number in the set. The median is also the number that is halfway into the set.
72, 77, 77, 77, 70, 75, 70, 67, 76, 73
There are ten numbers, so you solve the equation:
10 ÷ 2 = 5
The fifth number is 70
The range of a set of data is the difference between the highest and lowest values in the set.
72, 77, 77, 77, 70, 75, 70, 67, 76, 73
The greatest number is: 77
The lowest number is: 67
So you find the difference between them:
77 - 67 = 10

Answer:
The value of n
n = 0.86
n = -0.73
Step-by-step explanation:
Given:
The given equation is
We need to find the value of n when d = -2n.
Solution:
Rewrite the given equation as
Substitute d = -2n in above equation.
Now, we first find the root of the above equation.
Use quadratic formula with .
Put a, b and c value in above equation.
For positive sign
n = 0.86
For negative sign
n = -0.73
Therefore the value of n = 0.86 or n = -0.73
