Standard Normal Distribution. As discussed in the introductory section, normal distributions do not necessarily have the same means and standard deviations. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution.
Sum of interior angles formula = (n-2) x 180
where n = number of sides
so,
( 19-2 ) x 180
= 17 x 180
= 3060
ans : A
hope it helps :)
Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
Answer:
(2/3) x + 17
Step-by-step explanation:
One way we can solve this is to start at x and to work from there.
Since x represents the number of baseball cards that Barry's brother has, and the closest phrase to it is "two-thirds of the number of cards", we can start by writing that as "2/3 of x", or (2/3) * x.
Next, we have "17 more than two-thirds of ...". We have 17 more than the number we just got, so we have 17 more than (2/3) * x = 17 + (2/3) * x = (2/3)*x + 17 as our answer
Answer:
x = 30.66°
Step-by-step explanation:
The sum of the interior angles of a hexagon is 720°
Each angles are x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100),
we add all these angles together
x^0 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100) = 720
x^0 = 1
1 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100)
1 + 5x - 103 +2x + 60 + 7x -31 + 6x - 6 + 9x - 100 = 720
1 - 103 + 60 - 31 - 6 - 100 + 5x + 2x + 7x + 6x + 9x = 720
1 - 180 + 29x = 720
-179 + 29x = 720
29x = 720 + 179 = 889
x = 889/29 = 30.655 ≅ 30.66°
