If line b is perpendicular to line a, and linec

1 answer:

4 0

Since both lines c and b are perpendicular to line a, line c and b are parallel.

Using the two points on line b, we can count “up 5, right 5” to find the slope of line b to be 5/5 or 1.

Since line b has a slope of 1 and line c is parallel, it must also have a slope of 1.

Given that 7 x − 2 y = 35 Find y when x = − 9

Sergio [31]

so x = minus 9

then

7 × (-9) - 2y = 35

-63 - 2y = 35

-2y = 35 plus 63

-2y = 98

- y = 49

y = -49

arsen [322]

Answer: $P(B|A)=\dfrac{4}{9}$

Step-by-step explanation:

Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.

Event A is defined as drawing a white ball on the first draw.

Event B is defined as drawing a black ball on the second draw.

P(B|A) is expressed as the conditional probability of occurring B given that A.

i.e. it is the probability of happening B where A is already happended.

If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.

$Probability=\dfrac{Number\ of \ favorable \ outcomes}{Total\ outcomes}$

Then, $P(B|A)=\dfrac{4}{9}$
