9 sides
Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.

Artist 52 [7]
We have 4 apples, 3 peaches, and  4 pears.
The sample size is 11.

1st selection: apple
The probability of selecting an apple is 4/11.

2nd selection: peach
We now have a sample size of 10, which consists of 3 apples, 3 peaches, and 4 pears.
The probability of selecting a peach is 3/10.

3rd selection: peach
We now have a sample size of 9, which consists of 3 apples, 2 peaches, and 4 pears.
The probability of selecting a peach is 2/9.

Each selection was an independent event. Therefore the overall probability is
(4/11)*(3/10)*(2/9) = 4/165

Answer:
The probability of selecting an apple followed by 2 peaches is 4/165.
 This probability is equivalent to 0.024 or 2.4%.

Slope of -5 2). (3,9)
podryga [215]

Answer:

The slope of the given two points is m=\frac{7}{8}

Step-by-step explanation:

Given two points are (-5,2) and (3,9)

To find the slope with these two points

Let (x_{1},y_{1}) and (x_{2},y_{2}) be the given points

By using Slope Formula:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{9-2}{3-(-5)}

m=\frac{9-2}{3+5} ( subtracting and adding the corresponding terms)

m=\frac{7}{8}

Therefore slope is m=\frac{7}{8}

The slope of the given two points is m=\frac{7}{8}
