The median of the data set is 81 what number is missing in data set 82, 87, 77, 70, 80, 88
Answers
The missing dataset is 81 at the 4th position.
We have the following data set -
82, 87, 77, 70, 80, 88
whose Median is - 81
We have to find out the missing data in this dataset.
What is the formula to find the Median of a set of odd number of elements (say N) ?
If a set consist of odd number of elements, then the median of that set of numbers is the is the element at the position .
Let the missing element be x. Now, the data set becomes -
82, 87, 77, 70, 80, 88, x
To total number of elements in the dataset = 7, which is a odd number.
The element at the position for odd number of elements equals to Median which is equal to 81.
Hence, the missing dataset is 81 at the position - = 4th position.

Answer as decimal form: 1.9.
The simplification of the given mixed number expression is equal to 1 9/10.
To perform the division of mixed numbers 2 3/8 ÷ 1 1/4, follow these steps:
Convert the mixed numbers to improper fractions.
2 3/8 = (2 × 8 + 3) / 8 = 19 / 8
1 1/4 = (1 ×4 + 1) / 4 = 5 / 4
Take the reciprocal of the divisor (the second fraction) to turn the division into multiplication.
Reciprocal of 5 / 4 is 4 / 5.
Multiply the dividend (the first fraction) by the reciprocal of the divisor.
(19 / 8) × (4 / 5) = (19 × 4) / (8 × 5) = 76 / 40
Simplify the result if possible.
To simplify the fraction 76 / 40, divide both the numerator and denominator by their greatest common factor (GCF), which is 4.
76 ÷ 4 = 19
40 ÷ 4 = 10
The simplified fraction is 19/10.
Convert the improper fraction back to a mixed number (if needed).
19/10 can be written as 1 9/10.
Therefore , the answer of the simplification to 2 3/8 ÷ 1 1/4 is 1 9/10.
