Answer:

(B) a = 41%, b = 3%

Step-by-step explanation:

The result from the survey is given below:

\left|\begin{array}{c|c|c|c}&Enjoy&$Did not Enjoy&$Total\\--&--&--&--\\Male&47&13&60\\Female&53&3&56\\Total&100&16&116\end{array}\right|

The second table is given as:

\left|\begin{array}{c|c|c|c}&Enjoy&$Did not Enjoy&$Total\\--&--&--&--\\Male&a&11\%&\\Female&46\%&b&\\Total&&&100\end{array}\right|

Now, from the first table

Total Number of Respondents =116

Therefore:

\dfrac{47}{116}*100 \approx 41\%\\\dfrac{13}{116}*100 \approx 11\%\\\dfrac{53}{116}*100 \approx 46\%\\\dfrac{3}{116}*100 \approx 3\%

Therefore:

a=41%

b=3%

The correct option is B.

Mathematics help please!!!!!!!!!<br><br> what is -0.0833333333333 converted into a fraction?
VladimirAG [237]

Answer:

- 1/12

Step-by-step explanation:

Let -0.0833333 = x  ---  (1)

Multiply both sides by 10.

-0.833333 = 10x   --- (2)

Subtract (2) from (1),

0.75 = -9x

-9x = \frac{75}{100}

= \frac{3}{4}

x=-\frac{3}{36}

x=-\frac{1}{12}
