Answer:
The representative sample contained more girls than boys.
Step-by-step explanation:
Solution:-
- Denote the number of boys going on trip, B = 65
- Denote the number of boys going on trip, G = 95
- The total of T = 160 students are going on the trip.
- We are to randomly select a representative sample from the population of students with T = 160 students in total.
- The proportion of boys population ( p ) among the total population can be determined:
p = B / T
p = 65 / 160
p = 0.40625
- The proportion of girls population ( q ) among the total population can be determined:
q = G / T
q = 95 / 160
q = 0.59375
- For us to select a representative group of sample size ( n ) from the population of 160 student. The possibility of finding a girl on that representative group is q = 59.4 % while the possibility of finding a boy on that representative group is p = 40.6 %.
Answer: We are likely to see more girls as part of the representative group as compared to boys.
The area of a triangle can be found by multiplying the base and the height, and dividing the product by 2.
So, 10*8=80
80/2=40 in^2
Then, the triangle on the left:
10*12=120
120/2=60 in^2
Add up the areas
40 in^2+60 in^2=100 in^2
