Answer:
-5
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
= ( -12.5 - -2.5)/( 7.3 - 5.3)
= ( -12.5 +2.5)/( 7.3 - 5.3)
= -10 /2
= -5
Answer:
A and F
Step-by-step explanation:
first figure out the slope.
4-(-5)/2-(-3)= 9/5
slope: 9/5
y-y1=m(x-x1)
you substitute either coordinate for the second variables. we automatically take out any slopes that have a negative because the slope is positive.
C, D, E all have negative slopes so it is wrong.
B does not work because a negative times a negative is a positive. the equation shows it to be negative so it is wrong.
A & F fit the solution.
Answer:
b) .474
Step-by-step explanation:
If 62% go to a four-year college, that means that those who don't represent 38% of the high-school graduates.
You pick up someone who is NOT going to a four-year college (so, he's among the 38%)... what's the chance he's in the 18% of the whole high-school graduates population that found a job?
To calculate that probability, we have to divide 18% by 38%.
P = 18% / 38% = 0.4736, so 0.474
Since we are sure he doesn't go to a four-year college, there's 47.4% of chances he finds a job.
