Answer:
11+6=17
Step-by-step explanation:
Choice A
Reasoning
26=7(g-9)+12
26=7(11-9)+12
26=7(2)+12
26=14+12
26=26
Given:
The inequalities are:
or
To find:
The solution for the given inequalities and graph the solution.
Solution:
We have,
or
Solve the above inequalities separately.
Divide both sides by -5.
...(i)
And,
Divide both sides by 2.
...(ii)
From (i) and (ii). we get
or
The interval notation of the solution is .
The graph of the solution is shown below.
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%.

Answer:
y= 77° x=103°
Step-by-step explanation:
x=103° Alternate angles are equal
y=77° angles on a straight line sum to 180° (180°-103°=77°)
