Answer:
x= 16.53
Step-by-step explanation:
Since this is a right triangle we can use the law of cosine (adjacent/hypotenuse) to solve. You get the equation cos(49)=x/55. You then wanna multiply 55 to both sides so you can isolate x. You get 55*cos(49)=x. Then, you put 55*cos(49) into a calculator and multiply to get 16.5325899059.... Then round to the nearest hundredth to get 16.53 as your answer.
Hope this helps :) (its been a while since I've done trig ratios so thanks for the refresher)
<u><em>A</em></u> would be correct hope I helped.
The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19). The total number of people who took less than 7.63 electives is 10. Therefore, the required sample proportion is 10 / 19.
