Answer:
Mean = 7
Median = 7.65
Mode = 4.4
Range = 9.9
Step-by-step explanation:
The question is incomplete as it doesn't state what to find. Lets complete the question first. The complete question states that:
Calculate the following for the data set
Mean
Median
Mode
Range
<h3>A) Mean</h3>
Mean = sum of values/ total number of values
Mean = 84/12
Mean = 7
<h3>B) Median</h3>
Arrange the data in ascending order
1.8, 2.5, 2.6, 4.4, 4.4, 7.3, 8.0, 9.5, 10.3, 10.4, 11.1, 11.7
Median = Average of middle values
Median = (7.3+8.0) / 2
Median = 7.65
<h3>C) Mode</h3>
Mode = number which appears most = 4.4
<h3>D) Range</h3>
Range = Max value - Min value
Range = 11.7 - 1.8
Range = 9.9

C
given 1 /( 3 + √2 )
then rationalise the denominator by multiplying the numerator/ denominator by the conjugate of the denominator
the conjugate of 3 + √2 is 3 - √2
1 / (3 + √2 ) × (3 - √2 ) / (3 - √2 )
= (3 - √2 ) /( 9 - 2 ) = (3 - √2 ) / 7
