In the adjoining figure prove that&lt;A+&lt;B+&lt;C+&lt;D+&lt;E is equal 180​
Naya [18.7K]

It has been proved that the 5 star vertices have their sum of angles as A + B + C + D + E = 180°

<h3>How to find the sum of angles of a polygon?</h3>

The adjoining star contains a regular pentagon. Thus;

Sum of interior angles of the pentagon = (5 - 2) * 180 = 540°

Thus;

Each interior angle of the pentagon = 540/5 = 108°

Thus, each exterior angle = 180 - 108 = 72°

Then measure of the angle at the vertex = 180 - 72 - 72 = 36°

Thus, each angle at the vertices of the star have an angle of 36°.

There are 5 star vertices and so;

Sum of angles of 5 star vertices = 5 * 36 = 180°

The probability that a certain hockey team will win any given game is 0.3773 based on their 13 year win history of 389 wins out
notsponge [240]

Answer:

0.8895 = 88.95% probability that the hockey team wins at least 3 games in November.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the teams wins, or they do not win. The probability of the team winning a game is independent of any other game, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

The probability that a certain hockey team will win any given game is 0.3773.

This means that p = 0.3773

Their schedule for November contains 12 games.

This means that n = 12

Find the probability that the hockey team wins at least 3 games in November.

This is:

P(X \geq 3) = 1 - P(X < 3)

In which:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{12,0}.(0.3773)^{0}.(0.6227)^{12} = 0.0034

P(X = 1) = C_{12,1}.(0.3773)^{1}.(0.6227)^{11} = 0.0247

P(X = 2) = C_{12,2}.(0.3773)^{2}.(0.6227)^{10} = 0.0824

Then

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0034 + 0.0247 + 0.0824 = 0.1105

P(X \geq 3) = 1 - P(X < 3) = 1 - 0.1105 = 0.8895

0.8895 = 88.95% probability that the hockey team wins at least 3 games in November.

Evaluate the expression when: A=2, B=1, C=4<br> A+6/CB
vovikov84 [41]

Answer:

Imma rewrite the question as: 2+6/41

2+6=8

i think since the letters were next to each other u multiply?? Is so...:

4x1=4

8+4=12

=12

but if u add the letters next to eachother....

2+6=8

4+1=5

8+5=13

=13

or if u use “41” as a whole number and add it in..:

2+6=8

8+41=49

=49
