A gold, a silver, and a bronze medal are awarded in an Olympic event. In how many possible ways can the medals be awarded for a 200-meter sprint in which there are 10 runner?

Answers

Answer 1

Answer:

720 possible ways

Step-by-step explanation:

The gold is awarded to the first position, the silver is awarded to the second position while the bronze is awarded to the third position.

The first position can be taken by any of the 10 runners

Now, the second position can be taken by remaining 9 runners

while the third position can be taken by the renaming 8 runners.

Thus, the number of ways in which these medals can be awarded = 10 * 9 * 8 = 720 ways

Converse of the corresponding angles postulate

============================================

Explanation:

The corresponding angles postulate says that if we have two parallel lines, then the corresponding angles are congruent.

The converse of this is where we go in reverse: if we know the corresponding angles are congruent, then the lines are parallel.

Corresponding angles are ones where they are on the same side of the transversal line, and also on the same side of each adjacent parallel line. In this case, the angles 52 are to the right of the tranversal, and each are above their neighboring parallel line. We could say the two corresponding angles are both in the upper right hand corner (think of the two lines crossing to form 4 corners or regions)

What is the sum of the first 14 terms of the sequence -11+(-18)+(-25)+(-32)...-791
-483
-102
-714

Answers

the difference between -11 and -18 is -7
the difference between -18 and -25 is -7
the difference between -25 and -32 is -7

therefore we can say that the difference between all of the terms will be -7.

the first term is -11 -> call this a
the difference is -7 -> call this d
the number of terms is 14 -> call this n

use the equation (sum of) $_(n)$ = $(n)/(2)$ (2a + (n-1)d)

(sum of) $_(n)$ = $(14)/(2)$ (2 x -11 + (14-1)-7)

= -7(-22 + (13 x -7))
= -7(-22 + -91)
= -7(-111)
= 777
