First of all we have to arrange the data in ascending order as shown below:
28, 40, 43, 43, 45, 50, 50
Total number of values = 7
Since the number of values is odd, the median will be the middle value i.e. 4th value which is 43. Median divides the data in two halves:
1st Half = 28, 40, 43
2nd Half = 45, 50, 50
Q1 or the First Quartile is the middle value of the lower or 1st half which is 40.
Q3 or the Third Quartile is the middle value of the upper or second half, which is 50.
IQR or the Inter Quartile Range is the difference of Q3 and Q1.
So, IQR= Q3 – Q1 = 50 – 40 = 10
Thus, IQR for the given data is 10
Answer : 4123
Explanation:
Answer:
The polynomial
is in standard form.
Step-by-step explanation:
Writing the polynomial in standard form means we have to write the terms of the polynomial by descending degree.
- First writing the term with the highest or largest exponent or degree first
- Then writing the terms which have lower degrees/exponents in descending order.
- If there is any constant term in the polynomial, it is always written in the end.
so
Given the polynomial

Here:
- The highest exponent is the 4, so that entire term i.e.
is written first. Here it is also written first.
- Then the next term is the constant term, and constant terms is written in the end. Here, the constant terms is also written in the end.
Therefore, the polynomial
is in standard form.
