Answer:
612 students and 325 adults.
Step-by-step explanation:
To determine the number of adults and students who attended the event, knowing that in total there were 937 people who spent a total of $ 1,109 and that each student ticket is worth $ 0.75 while each adult ticket is worth $ 2, the following logical reasoning must be performed:
2 - 0.75 = 1.25
Therefore, the minimum that each ticket will be worth is $ 0.75, while there will be a surplus of money that will be divisible by 1.25, which is the amount of more that each adult paid on their ticket.
Therefore, since 0.75 x 937 equals 702.75, the total price surplus is 406.25 (1,109 - 702.75). Now, this number divided by 1.25 gives a total of 325, with which 325 adults attended the event. In turn, given that the total number of attendees was 937, the total number of students who attended the event is 612 (937 - 325).
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.
Yes, because only equal groups can be multiplied
Answer:
When there is no width, the area is 0m²
Step-by-step explanation:
Expressing the area of a rectangle as a function of its width:
Area of a rectangle = Length * width
Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0
When x :
Area = Length * width
Area = Length * 0
Area = 0
Area = Length * 0
Aea = 0
Answer:
the slope is 0
Step-by-step explanation:
because it passes right through the middle
