If 11 like basketball and 16 like hockey, you get a total of 27, but if 2 said both then you don't want to double count them, so a total of 25 students answered. If 25 total students answered but 2 liked both, then 23 only liked one.
The answer to (a) is 5 students did not like either sport
The answer to (b) is 23 students liked exactly one sport.
31 times 2 is the answer you seek

Answer:
A
Step-by-step explanation:
In a list of ordered pairs, a relation that is a function will not have any repeated x-values.
A -- a function (x-values are {-1, 0, 2, 5} with no repeats)
B -- irrelevant
C -- not a function (x-values are {0, 0, -3, 3} with 0 being repeated)
D -- not a function (x-values are {-2, -1, -2, 2} with -2 being repeated)
Answer:
The Answer is 27.78
Step-by-step explanation:
<em>First,</em><em> we need to find the total amount of students,</em>
<em>12 + 10 + 14 =36</em>
<em>Secondly,</em><em> we need to find the percentage of fanta.</em>
<em>10 ÷ 36 = 0.2778</em>
<em>0.2778 × 100 = </em>
<em>27.78</em>
<em>Therefore, </em><em>the answer is </em><em>27.78%</em>

Answer:
The answer is 1/x-3
Step-by-step explanation:
2/x−3+3/x+2−(4x−7/x2−x−6)
