Answer:
599/711
Step-by-step explanation:
Band Sports Debate Total
Male 105 320 7 432
Female 105 160 14 279
Total 210 480 21 711
P(female or plays sports)
We want the probability that they are female or play sports, but we cannot double count the female sports players, so we subtract them
P(female) + P (sports) - (female and sports)
female/total + sports/total - female sports/ total
279/711 + 480/711 - 160/711
599/711
I guess this is the answer.
Answer:
and 
(None of the answer choices fits. See explanation below)
Step-by-step explanation:
In mathematics, the modulus of a number, denoted by enclosing the number within vertical bars is the absolute value of the number. If the number is negative the sign is disregarded and the number is treated as positive
For example,
and
is also 
Solve for
in the equation

Subtracting 4 on both sides yields 
Simplifying 
Multiplying by 2 on both sides yields 
We do not know if |x-3| is negative or positive since 
So we have 2 possibilities
If
is negative, then
==> 
If
is positive, then
==> 
So the possible values are
and 
None of the answer choices fits these values indicating either an error in the answer choices or the original equation
