Answer:
x = 9, ∠ 1 = ∠ 2 = 66°
Step-by-step explanation:
If r and s are parallel then
∠ 1 = ∠ 2 ( corresponding angles ) , then
84 - 2x = 93 - 3x ( add 3x to both sides )
84 + x = 93 ( subtract 84 from both sides )
x = 9
Then
∠ 1 = 84 - 2x = 84 - 2(9) = 84 - 18 = 66°
∠ 2 = 93 - 3x = 93 - 3(9) = 93 - 27 = 66°
Answer:
B. 45/8
Step-by-step explanation:



A + b
= -10 + 4
= 4 - 10
= -6
$ 10
250 * 2 =300
5*2=10
So the answer is $ 10
Answer:
The expected value is an expression of the weighted average and can be taken as the (arithmetic) mean
As the number of trials is increased in a binomial experiment, the expected values obtained, in each of the set of trials continuously tend to the theoretical expected value
