Answer:
Highlight the important information in the problem that will help write two equations.
Define your variables.
Write two equations.
Use one of the methods for solving systems of equations to solve.
Check your answers by substituting your ordered pair into the original equations.
Step-by-step explanation:
Answer:
B. Parameter
Step-by-step explanation:
When something is taken from a sample and estimated to the entire population, it is a statistic. For example, if you survey 200 Central New York residents, an 60% of them say they are Buffalo Bills fans, the 60% is a statistic.
When something is true to the entire population, it is a parameter. If i study the voting preference of all 53 players on the Buffalo Bills active roster, and 83% are Democrats, the 83% is an parameter.
In this problem, we have that:
Of all DeVry students, a study found that 43% of them are business majors.
The keyword is all, meaning that the 43% is true for the entire population.
So the correct answer is:
B. Parameter
Segment addition postulate says
AB+BC=AC
assuming that A, B, C are in order, and assuming that those are the points,
legnth of AC=|A-C|=39 (|x| means absolute value of x)
A=2x-8
b=17x
AB=|A-B|=|2x-8-17x|=|-8-15x|
we are only given AB but not BC so this is not solvable unless you know BC
AB+BC=AC
BC=AC-AB
BC=39-|-8-15x|
that's as far as I can go since we don't know any more
