Answer:
cubic units
Step-by-step explanation:
Volume of the square pyramid is given as ⅓*area of base*height of pyramid.
Where,
Area of base = 6*6 = 36
Height of pyramid = altitude = units
Plug the values into the formula to find volume.
cubic units
The answer is: There are a total of 16 skits in the video.
<h2>Why?</h2>From the statement, we know that the total length of the video is 101 minutes and it contains a 5-minute introduction, the rest of the minutes are short skits (which are 6 minutes long each one).
So, we need to write the following equations:
First equation:
Second equation:
Where,
So, replacing and substituting the second equation into the first equation we have:
So, there are a total of 16 skits in the video.
Let's prove it substituting "n" into the first equation:
Have a nice day!
We know that our bag has n white tiles and 5 black tiles.
So, the total number of tiles in the bag is n + 5.
We know that a tile is drawn at random and is replaced, then a second tile is drawn.
a) We want to find the probability that the first tile is white.
Because all the tiles have the same probability of being randomly drawn, the probability of drawing a white tile is just the quotient between the number of white tiles and the total number of tiles in the bag.
And for the second draw, we do not have any restrictions, so the probability is the above one.
b) Now we want both tiles to be white.
For the first one we already know the probability, which is:
And because the tile is replaced, the probability of drawing a white tile again is exactly the same:
The joint probability (the probability of both of these outcomes to happen together) is the product of the individual probabilities.
Probability =
