Answer:
Step-by-step explanation:
2(x+2) = 10
divide by 2 each side
x+2 = 5
subtract 2 on each side
x = 3
The above figure depicts :
Answer:
They are equivalent
Step-by-step explanation:
We can do cross products for this one
17/3 = 68/12
17 times 12 = 68 times 3
204 = 204
Using the combination formula, it is found that:
There are 364 different orders of top-three finishers that include all seniors.
The probability that the top-three finishers will all be seniors is 15.38%.
The order in which the players are taken is not important, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In total, three students are taken from a set of 14, hence:
Including only seniors, it would be three students from a set of 8, hence:
Hence the probability is given by:
p = 56/364 = 0.1538 = 15.38%.
