Answer: 50
Step-by-step explanation:
Triangle LNK equals 180 degrees, we know that angle N is 58 degrees and angle NLK is 72 degrees, so we can just subtract 72 and 58 from 180 to get angle LKN. Hope that helps
Answer:
Is unbiased estimator
Step-by-step explanation:
In statistics, Numerical characteristics derived from population data is referred to as parameter, while those derived from the sample data are called statistic. When a sample is drawn from a particular population, the statistic of such sample could be used as either a point or interval estimate of the population. However, the estimator derived from the sample in most cases isn't equal to the exact parameter value. When this happens, that is, when population parameter equals the estimate of the sample statistic, then we have an unbiased estimator.
Answer:
1 / 30
Step-by-step explanation:
For a six - sided die :
Sample space = (1, 2, 3, 4, 5, 6)
P(rolling a 1) = required outcome / sample space = 1/6
Sample space for spinner = (A, B, C, D, E)
P(spinning A ) = required outcome / sample space = 1/5
P(spinning A) = 1 / 5
P(rolling a 1 and spinning A) = P(rolling a 1) * P(spinning A) = 1/6 * 1/5 = 1 / 30
Line EB is the mid segment of the triangle
EB and DC are parallel if angle EBA is equal to angle DCB
so
4x - 3 = 3x + 9 now solve for x
-3x -3x
x -3 = + 9
-3 -3
x = 12
Now I know x and 3x +9, so sub in for x
3(8) + 9 = 32 + 9 = 41
now we know angle EBA
and angle EBA and angle EBC are a linear pair meaning when I add them together they equal 180
so
angle EBA + angle EBC = 180
41 + 14y - 5 = 180 now solve for y
36 + 14y = 180
-36 -36
14y = 144
/14 /14
y = 10.28
