Answer:
Population: The entire number of students present in town’s high school.
Sample: Identical number of students across various categories of freshers, senior students and juniors.
Step-by-step explanation:
Population is the large set of the people who are present during the experiment. Sample is a smaller subset from the population who become a part of the experiment. In this question, samples are the students who are either new joiners to the college, the senior students or the juniors. It will help Alan to come to a possible conclusion using the survey
Answer:
is there a link?
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
D
An equation in point-slope form that passes through point P(a,b) is as follows:
y-b=m(x-a) where m=slope, a,b are coordinates of point P.
For a line to pass through P(4,-8)
the equation will look like:
y-(-8) = m(x-4)
simplify left side
y+8=m(x-4)
The given equation has a slope of m=-1/2, so the slope of a line perpendicular to it has a slope of -1/m = -1/(-1/2)=+2
Now go through the answer choices:
a. y+8=2(x-4) => passes through P(4,-8) and has a slope of 2. so TRUE
b. y-4=2(x+8) => has a slope of 2, but passes through (-8,4), which is not P so FALSE
c. y+8=(1/2)(x-4) => passes through P(4,-8), but has the wrong slope (a reflection, not perpendicular) so FALSE
d. y-8=(1/2)(x+4) => passes through a wrong point (-4,8) and has the reflected slope (not perpendicular) so FALSE
