The constant that can be added to 
- 3x to form a perfect square trinomial is 
The given expression is
- 3x
To form a perfect square trinomial
The given expression is
- 3x
first we have to add a constant term with it
- 3x + z
By comparing the given expression and the perfect square trinomial
a = x
Similarly
-2ab = 3x
where know a =x
Then,
-2b = 3
b = -3/2
Similarly
= z
9/4 = z
Convert the simple fraction to mixed fraction
9/4 =
Hence, the constant that can be added to - 3x to form a perfect square trinomial is

Answer:
1/5
Step-by-step explanation:
Range as a measure of central tendency is the difference between the highest value and the lowest value in a given set of data.
Given the samples 0,1,3,4,7
Total number of samples is 5
The range is gotten by taking the difference of 2 samplesout of 5samples and this can be done in 5C2 ways.
5C2 = 5!/(5-2)!2!
= 5!/3!2!
= 5×4×3!/3!×2
= 10ways
The total outcome is therefore 10
To get the probability that the range is 4, we need to get the required outcome of getting range of 4 and this can only occur twice
The range can be gotten by taking the difference between 7 and 3, it can also be gotten by taking the difference between 4 and 0. Both differences will give us a total of 4
The expected outcome is therefore 2
the probability that the range of the sample is 4 = expected outcome/total outcome
= 2/10
= 1/5
