If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed?
Lynna [10]
There are 6, you'd think there would be 8 but the answer is actually 6. A diagonal is a line segment that connects to vertices, the two vertices chosen do not count when forming the triangle, two vertices that are adjacent to that chosen vertex are NOT included when forming the diagonal. It's confusing, but I hope this helps. If you have any follow up questions I'd love to answer them.

The length of a shadow of a tree is 9 ft. The distance from the top of the tree to the tip of the shadow is 16 ft. what is the h
Margarita [4]
So for this, you'll be using the pythagorean theorem to solve for the height.

9^2+b^2=16^2

Solve the exponents to get 81+b^2=256

Subtract 81 on each side to get b^2=175

Square root each side, and your answer should be b= \sqrt{175} or 13.23 ft

PLEASE HELP ME with an explanation. Thanks in advance

Answer:

3) 0.30

The probability a randomly selected<em> student plays a sport</em> given they work part time = 0.30

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given  'A' plays a sport

          B work part time

Given P(A) = 0.48

         P(B)  = 0.40

        P(A∩B) =0.12

       P(A∪B)¹ =0.24

<u><em>Step(ii)</em></u>:-

By using conditional probability

P(B/A) = \frac{P(BnA}{P(A)}

and similarly P(A/B) = \frac{P(AnB}{P(B)}

The probability a randomly selected<em> student plays a sport</em> given they work part time

Now P(A/B) = \frac{P(AnB}{P(B)}

       P(A/B) = \frac{0.12}{0.40}= 0.30

<u>Final answer</u>:-

The probability a randomly selected<em> student plays a sport</em> given they work part time = 0.30
