we know that
If line b is perpendicular to line a, and line c is perpendicular to line a,
then
line b and line c are parallel
and two lines parallel have the same slope
so
<u>Find the slope of the line b</u>
Let

The formula to calculate the slope between two points is equal to


substitute



therefore
<u>the answer is</u>
<u>the slope of the line c is</u>

Answer:
the answer is c
Step-by-step explanation:
Answer:
1) 0.5 or 50%.
2) Order does not matter: 3,003 combinations.
Order matters: 360,360 permutations.
Step-by-step explanation:
1) The probability of drawing either a purple or a blue chip is the sum of both individual probabilities:

the probability that a blue or a purple chip will be drawn is 0.5 or 50%.
2)
a) Choose 5 items from a total of 15 items when order does not matter:

b) Choose 5 items from a total of 15 items when order matters:

Lets take Gregs weight as “x”. This means that Justins weight is x-15, and x/2 = (x-15)-75.
If we take that last equation, lets combine like terms:
x/2 = x - 15 - 75
x/2 = x - 90
Now multiply both sides by 2 to get rid of the fraction
x = 2x - 180
Subtract 2x from both sides
x - 2x = -180
-x = -180
x = 180 — this is Gregs weight
Justins weight is x-15, so 180-15, which is 165 pounds. Hope this helped.
Answer: 448 hours
Step-by-step explanation:
272 divided by 17 = hourly wage
hourly wage= 16$
448 divided by 16 = 28 weeks
28 x 16= 448 hours
