Answer:
√55 ≈ 7.4
Step-by-step explanation:
The easiest way to find the square root of 55 is to use a calculator.
√55 ≈ 7.4161984871
Rounded to the nearest tenth, this is ...
√55 ≈ 7.4
__
You can make a first approximation of the root by linearly interpolating between the roots of the perfect squares* on either side of 55.
√49 = 7
√64 = 8
√55 ≈ 7 +(55 -49)/(64 -49) = 7 6/15 = 7 2/5
√55 ≈ 7.4
_____
* For numbers greater than 3.3, this sort of approximation will give the value of the root accurate to the nearest tenth. The approximation is better for larger numbers.
Answer:
Answer is A
Step-by-step explanation:
Answer:
Step-by-step explanation:
percentage of graduates with loan = 62%
total sample = 50
Number of student in the sample with student loan
= (percentage of graduates with loan) x (total sample)
= 62% x 50
= 31
Proportion of student in the sample with student loan =
