Answer:
QS = 15
Step-by-step explanation:
Thales
QS/QT = RS/PT
QS = QT·RS/PT
= 20×12/16
= 240/16
= 15
Answer:
Population is 34000 students
Sample is 770 students
Step-by-step explanation:
Population :In statistics, a population is the entire pool from which a statistical sample is drawn.
Sample: A sample refers to a set of observations drawn from a population.
We are given that 34,000 students attended the university.
Out of which a random sample of 370 male students and 400 female students was selected
So, Total students selected = 370+400=770
So, Population is 34000 students
Sample is 770 students
So, Option C is true.
The answer is the last option: The associative property of multiplication
Let's assume
x is number of hours worked
y is amount paid
Since, this is linear relationship
We can select any two points
(2,36.50) and (4,73)
so, we can also write as
x1=2 , y1 =36.50
x2=4 , y2=73
Firstly, we can find slope

we can plug values


now, we can use point slope form of line

we can plug values

now, we can solve for y
