Your Answers are : a) D b) C
Ответ:
567 students.
Step-by-step explanation:
Here, According to the given information,
The ratio of students who like orange and total number of student participate in the survey =![\frac{34}{120}](/tpl/images/0277/1431/aa0ec.png)
Let x students out of 2,000 students like orange.
Thus, In this case, the ratio of students who like orange and total number of student participate in the survey =![\frac{x}{2000}](/tpl/images/0277/1431/651bd.png)
By the proportional reasoning,
Both ratio must be equal.
That is,![\frac{x}{2000}=\frac{34}{120}](/tpl/images/0277/1431/bf2eb.png)
⇒![x = 2000\times \frac{34}{120}](/tpl/images/0277/1431/c21a4.png)
⇒![x = \frac{68,000}{120}](/tpl/images/0277/1431/e7597.png)
⇒![x = 566.666666667\approx 567](/tpl/images/0277/1431/131c7.png)
Thus, out of 2000 students about 567 students select an orange as their favorite fruit.
