A shuttle train at a busy airport completes a circuit between two terminals every seven minutes. What is the probability that a passenger will wait more than 5 minutes for a shuttle train?
y = 3x+4
step-by-step explanation:
to find the slope
slope = (y2-y1)/ (x2-x1)
= (-8-4)/ (-4-0)
= -12/-4
= 3
using the slope intercept form of a line
y= mx+b
we know the slope is 3
we know the y intercept is 4 ( the point where it crosses the y axis or x=0)
y = 3x+4
isocolese triangle
we know that the line connect a and b is the hyptonuse
so first find the hypotonuse length using the distance formula, call the length c
since it is an isocolese triangle, the lengths of the legs are the same
using pythagorean theorem,
in this case, a=b since isocolese triangle so we get
or
we can find c so we can find the distances
we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c
if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where
and
intersect to find where they intersect
i'm not going to put an example because i have to go to class. i hope this explanation is enough
i think you would have to divide the money he had saved, which is $2,000 by the time he plans on exercising which is 40 hours, and the answer you get should tell you the answer to your question.
