Answer:
2X^2+5/2X-3/2=0
Step-by-step explanation:
To identify the equation use the following method
(X-a)(X-b)=0
Put values
a=-4
b=3/2
(X+4)(X-3/2)=0
X^2+4X-3/2X-3/2=0
X^2+(8X-3X)/2-3/2=0
X^2+5/2X-3/2=0
Here you would factor out a 1.7 because that is the coefficient in front of the j. When you factor, you are essentially dividing each term by the value you are factoring out
1.7j/1.7=j
-3.4/1.7=-2
So the final answer is 1/7(j-2)

Answer:
The mean is 39
The median is 42
Step-by-step explanation:
The median is the best measure of center for the above data because half of the values are less than the median and half of the values are more than the median. It's probably the best measure of center to use in a skewed distribution.
The measure of variability is the range because is the simplest measure of variability to calculate but can be misleading if the dataset contains extreme values.
The variability is 67.25
