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:
16w+40
Step-by-step explanation:
To simplify this equation you have to use the distributive property first. This means you multiply 4 by everything in the first set of parentheses and you multiply 6 by everything in the second set of parentheses. This leaves you with 4w+16+24+12w.
Next, you combine like terms by adding 4w and 12w to get 16w, and 16 and 24 to get 40.
So, your final answer is 16w+40.
I think the answer is A because the balance after 4 years is not on their and so we are trying to find the balance after three years. And after 3 years the balance is 805
2 consecutive numbers....x and x + 1
x(x + 1) = 182
x^2 + x = 182
x^2 + x - 182 = 0
(x - 13)(x + 14) = 0
x - 13 = 0
x = 13
x + 14 = 0
x = -14....not this one because it is negative
x + 1 = 13 + 1 = 14
ur 2 numbers are : 13 and 14
