A cactus casts a shadow 33 feet long. At the same time of day, Liam who is 6 feet tall, casts a shadow 9 feet long, as shown.
castortr0y [4]

Answer:

here's the solution :-

1.) =》the base of the larger triangle is the length of shadow formed by cactus .

so, length of cactus is : 33 feet.

2.) now, jn the smaller triangle formed by liam and it's shadow : -

=》

since both triangle form 90° the bases of both the larger and smaller triangles are parallel , so the base angles of larger triangle = corresponding base angles of the smaller triangle

hence, the both triangles are similar

( by A.A postulate )

now since the both triangles are similar, the the sides will be proportional ,

=》

\frac{9}{33}  =  \frac{6}{x}

=》

x =  \frac{6}{9}  \times 33

=》

x = 2 \times 11

=》

x = 22

so, length of the cactus = x = 22 feet

Crazy boy [7]

Answer:

In a state lottery, you must correctly select 5 numbers (in any order) out of 40 to win the top prize.

1. How many ways can 5 numbers be chosen from 40 numbers?

40C5 = \frac{40!}{5!\times35!} = 658008 ways.

2. You purchase one lottery ticket. What is the probability that you will win the top prize?

The answer is 5! ways or 120 ways.

Hence, probability of winning top prize =\frac{120}{658008} =0.0001 or 0.01 %

3. The order of the numbers mattered, will the probability of winning increase or decrease? Why?

The probability decreases.

The probability of winning a game when order matters is always less than the probability of winning a game when order does not matter. This is because the permutation is always greater than the combination.
