Answer:

The probability is 16%

Step-by-step explanation:

Let's call A the event in which there is rain tomorrow and B the event in which the football game is postponed.

So, Taking into account that the event A and B are independent, the probability that happens A and B is calculated as:

P(A∩B) = P(A)*P(B)

From the question, we know that P(A) is 80% and P(B) is 20%, so P(A∩B) is:

P(A∩B) = 0.8*0.2=0.16

Then, the probability that it will rain tomorrow and the football game will be postponed is 0.16 or 16%

A meter stick casts a shadow 2.4 m long at the same time a flagpole casts a shadow 9.7 m long. How tall is the flagpole

Luda [366]

The first thing we are going to do is draw a diagram of the situation to help us to solve the situation.
We an draw tow similar triangle between the length of the shadows and the height of the stick and the pole.
Since <span>meter stick has a length of 1 meter, the height of our smaller triangle is 1 meter. Let </span> $h$ be height of of the pole. Since both triangles are similiar we can establish a proportion between their corresponding sides and solve for $h$ :
$\frac{h}{1} = \frac{9.7}{2.4}$
$h=\frac{9.7}{2.4}$
$h=4.04$

We can conclude that the pole is 4.04 meters tall.
