If two points on a line are A(10, −3) and B(12, 9), the rise is __________, and the run is __________, so the slope of the line
kherson [118]

The <u>rise</u> is the difference in y-coordinates:

  • y₂ - y₁ = 9 - (-3) = 12

The <u>run</u> is the difference in x-coordinates:

  • x₂ - x₁ = 12 - 10 = 2

The <u>slope</u> is the quotient of rise over run:

  • m = 12/2 = 6

========================

If two points on a line are A(10, −3) and B(12, 9), the rise is <u>12</u>, and the run is <u>2</u>, so the slope of the line is <u>6</u>.

A bag contains n white tiles and five black tiles. The tiles are all equal in shape and sizes. A tile is drawn at random and is
pochemuha

We know that our bag has n white tiles and 5 black tiles.

So, the total number of tiles in the bag is n + 5.

We know that a tile is drawn at random and is replaced, then a second tile is drawn.

a) We want to find the probability that the first tile is white.

Because all the tiles have the same probability of being randomly drawn, the probability of drawing a white tile is just the quotient between the number of white tiles and the total number of tiles in the bag.

P = n/(n + 5)

And for the second draw, we do not have any restrictions, so the probability is the above one.

P = n/(n + 5)

b) Now we want both tiles to be white.

For the first one we already know the probability, which is:

P = n/(n + 5)

And because the tile is replaced, the probability of drawing a white tile again is exactly the same:

Q =n/(n + 5)

The joint probability (the probability of both of these outcomes to happen together) is the product of the individual probabilities.

Probability = P*Q = (n/(n + 5))^2

Solve for x. Round to the nearest tenth of a degree, if necessary.​
MissTica

Answer:

x ≈ 54.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{PQ}{QR} = \frac{7.1}{5} , then

x = tan^{-1} (\frac{7.1}{5} ) ≈ 54.8° ( to the nearest tenth )
