I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo,
<em>A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2. </em>
<em>What is the volume of the pyramid?</em>
My answer:
As we know, The volume of a pyramid = base area × its height
Given:
- Side lenght of the base is;
=> The area of the base is
- In Δ ACB measure of angle ACB is 90° and m∠ CAB is 30°
We use:
<=> BC =
= 4 cm
And BC is the height of the the pyramid
=> The volume of a pyramid =
* 4 cm
=
Answer:
Step-by-step explanation:
Given that you and a friend play a game where you each toss a balanced coin.
If the upper faces on the coins are both tails, you win $1;
if the faces are both heads, you win $2;
if the coins do not match (one shows a head, the other a tail), you lose $1 (win (−$1)).
Let Y be the amount won
Then Y can take values as 1,2 and -1
The above is the probability distribution for Y.
