2. A(10;9), B(4;0), slope of 1.5

3. A(-35/4;6), B(9;-35/6), slope of -2/3

4. A(5;18), B(25,22), slope of 0.2

5. A(2/9;1/3), B(2/3,-1/3), slope of -1.5

Step-by-step explanation:

Substitute values with correct variable and slopemis coefficient of x when x and y-int. are on 1 side, y is on other side and has coefficient of 1. Hope it works!

Let's start with the given arc and its angle.

The angle YWX is going to be half the arc length.

YWX = 1/2 (226) = 113

Angles VWX and YWX form a linear pair (or are supplementary angles), which means that their sum is 180 degrees.

(15x - 8) + 113 = 180

15x + 105 = 180

15x = 75

x = 5

Hope this helps!

At an art exhibition there are 12 paintings of which 10 are original. A visitor selects a painting at random and before decides

Reika [66]

Answer:

a) 0.8333

b) 0.75

c) 0.8181 or 0.9090

Step-by-step explanation:

The probability the visitor selects an authentic painting is

10/12 = 0.8333

Since the opinion of the expert does not depend on your choice, the events are independent, so the probability that the expert says is authentic and it really is, is

0.8333*0.9 = 0.75

If the expert decides the painting is a copy and it is not, then there are 11 paintings of which 9 are authentic, so the probability the visitor selects a new original painting is

9/11= 0.8181

If the expert decides the painting is a copy and it is, then there are 11 paintings of which 10 are authentic, so the probability the visitor selects a new original painting is

10/11= 0.9090

✡ Answer: 200 ✡

- - Solve:

✡ First we need to find the formula to solve:
$\frac{3}{100} * x=6$

✡ Now:
x is equal to: $\frac{100*6}{3}$


✡Now we are going to multiply $100*2$ to get our answer.

- - 100*2=200
