The standard deviation is 1, I believe...
Answer:
Now, each student contributes= Rs 61 1/2= Rs 123/2 ( mixed fraction ).
Therefore, total no. of students=Rs (1953/2÷123/2) = 15.87
Rounding off 15.87 to 16.
There were 16 students
(i hope it is correct answer. pls mark as brainliest)
They would each be about 0.6875 pounds or 11 ounces.
As soon as you see "How many times . . .", that usually tells you that finding the answer involves <em>division</em>. (It certainly does in this one.)
(1.2 x 10⁵) / (4.9 x 10³) =
(1.2/4.9) x (10⁵⁻³) =
0.245 x 10² = <em>24.5 times</em>
It looks like <em>B</em> is the closest choice.
