Answer:
7 sides
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
Now, exterior angle of the point with interior angle of 120 is; 180 - 120 = 60 (angle on a straight line)
For the others, it is; 180 - 130 = 50
Thus;
60 + 50n = 360
50n = 360 - 60
50n = 300
n = 300/50
n = 6
Thus,number of sides = 6 +1 = 7 sides
Answer:
A: They are independent because P(X). P(Y) = PIX and Y).
Step-by-step explanation:
A) Two events X and Y are said to be independent if the probability of X occurring does not affect the probability of Y occurring or the probability of Y occurring does not affect the probability of X occurring. An example of independent events is the rolling of a die and flipping of a coin because the probability of getting a face in the die does not influence the probability of getting a head or tail in the coin. The probability of both events occurring is given as:
P(X and Y) = P(X).P(Y)

Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
