Answer:
<u>True </u>Postulates are used to prove theorems.
<u>True</u> Two points determine a line
Step-by-step explanation:
A postulate, in mathematics, is a numerical property that cannot be directly proven, but it is still present, and no has exceptions. Postulates are often used to prove theorems, particularly in geometry. An example of this can be found in the midsegment theorem which states that the average of the two bases in a trapezoid gives the length of the midsegment. Depending on how one chooses to prove this, one could potenitally need the Parts-whole Postulate theorem. Thus, one can state that Postulates are used to prove theorems.
A line can be drawn to connect any two given points. Therefore, one can states that two points determine a line, as only two points are needed for one to draw a line between them.

48 x 0.06 = 2.88 and thats how much tax you will pay!!
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.
