Answer:
13/145
Step-by-step explanation:
The average rate of change of f(x) on the interval [a,b] is f(b)−f(a) / b−a.
We have that a=0, b=8, f(x)=2x−1 / 3x+5.
Thus, f(b)−f(a) / b−a =
[{(2(8)−1)/(3(8)+5)} − {(2(0)−1)/(3(0)+5)}] / {8−(0)} =
13/145
Answer: (13) 128 (14) 3 (15) 38 (16) 21
Step-by-step explanation:
13) (x+3)+49=180
14) 66+8x=90
15) (x+3)+49=90
16) 3x+117=180

Answer:
C) Sample: the 120 students surveyed. Population: the 1200 students at the high school. Parameter of interest: the average number of hours a student at this high school sleeps per night.
Step-by-step explanation:
- Population is the total units of study for the research.
- Sample is the selected units, chosen for conducting the research study.
- Parameter of interest is the characteristic or variable, that is studied related to the population or sample
Research of average hours of sleep in a school; on the basis of 120 students selected for the study; are :-
- Population is the total number of students in the school, i.e = 1200 students
- Sample is the selected number of students, chosen (enquired) for the study, i.e = 120 students
- The parameter of interest is the variable of students, that needs to be studied, i.e average sleep hours.
Answer: y = 3/5x -5, y=3/5x + - 5
Step-by-step explanation:
Slope = Rise/run
intersect is at -5
