Answer:
The probability that the card selected bears a number less than 34 is 0.3333.
Step-by-step explanation:
Let random variable <em>X</em> be defined as the number on the selected card.
There are <em>N</em> = 15 total cards.
The number on the cards are as follows:
S = {25, 26, 27,..., 38, 39}
The probability of an event, <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.
In this case we need to compute the probability that the card selected bears a number less than 34.
The favorable outcomes are:
<em>s</em> = {25, 36, 37, 38, 39}
<em>n</em> (X < 34) = 5
Compute the probability that the card selected bears a number less than 34 as follows:
Thus, the probability that the card selected bears a number less than 34 is 0.3333.
Answer:
Length = 30
Height = 10
Step-by-step explanation:
Formula for the area = height * length. We know that the height of the wall is 1/3 of its length. This gives us another formula which is
Now substitute this into the formula, while knowing that the area is 300.
So we have 300 =
Solving for l gives us 30 and then substituting it back into the equation
, will give us that the height is 10.
Hope this helps
