Answer: 9

Step-by-step explanation:

Based on the information given in the question, the expected number of people who pass will be calculated as:

= Probability of passing the driving test × Number of people tested

= 65% × 15

= 0.65 × 15

= 9.75

Therefore, expected number of people who pass is 9.

Arithmetic of functions
Rzqust [24]

Its B.

If f(x)=4x+1 and g(x)=x^2-5 then, (\frac{g}{f})(x)=\frac{x^2-5}{4x+1} and x\neq-\frac{1}{4} because if x were -\frac{1}{4} then you would have division by 0.

Hope this helps.
