Angle ABD and Angle CBD are supplementary angles and Angle CBD and Angle DBE are complementary. If the measure of angle ABD is 1

gizmo_the_mogwai [7]

Answer:

54°

Step-by-step explanation:

ABD = 144°

ABD + CBD = 180°......(i)

CBD + DBE = 90°........(ii)

From (i)

144° + CBD = 180°

CBD = 180° - 144°

= 36°

From (ii)

CBD + DBE = 90°

36° + DBE = 90°

DBE = 90 - 36

= 54°

Find the expected value and the variance of the number of times one must throw a die until the outcome 1 has occurred 5 times.

Kazeer [188]

Answer: E(X) = 30; Var[X] = 180

Step-by-step explanation: This is a Bernoulli Experiment, i.e., the experiment is repeated a fixed number of times, the trials are independents, the only two outcomes are "success" or "failure" and the probability of success remains the same, So, to calculate Expected Value, which is the mean, in these conditions:

$E(X)=\frac{r}{p}$
