Those lines on the sides of x in the equation mean "absolute value". Which is a complicated way of saying "this number will never be negative". So if x = 2 then absolute value x= 2 but if x = -2 then absolute value x still is positive 2. Because of those brackets/lines (whatever they're called). So if you're given x=2 then it's simply saying y=4(2)-1 which is y=7
Answer:
2
Step-by-step explanation:
(12^0) + (((1.25 x 4) + 3) * ((1/2)^3)) = 2

Answer:
0.3333 = 33.33%
Step-by-step explanation:
We have 2 vacancies that will be filled from among 10 people, so the number of combinations we have is a combination of 10 choose 2, which is 10*9/2 = 45 possibilities.
Among these possibilities, the cases where the 2 vacancies are occupied by men is:
We have 6 men for 2 vacancies, so is a combination of 6 choose 2, which is 6*5/2 = 15 cases.
From the 45 cases we have, 15 are cases that no woman was selected, so the probability that no woman is selected is 15/45 = 1/3 = 0.3333 = 33.33%
Answer:
A=lw+l(w
2)2+h2+w(l
2)2+h2
Step-by-step explanation:
Let the width be w, then length = w + 4
Area = length x width = w(w + 4) = w^2 + 4w
f(w) = w^2 + 4w
for w = 8 in
Area = (8)^2 + 4(8) = 64 + 32 = 96 in^2
