The smallest possible value of z is the denominator of the reduced fraction x/y. We note the prime factors of the members of set y are
... 2², 7, 2³, 3²
so if there are any even members of set x, the fraction can be reduced to something divided by 2. The number 6 in set x is even, so we have
... 6z/4 = 6·2/4 = 3 (an integer) when z=2
The lowest possible value of z is ...
... B) 2
X= number of student tickets soldx+75= number of adult tickets sold
Add the number of student and adult tickets together to total 725 tickets
x + (x + 75)= 725
combine like terms
2x + 75= 725subtract 75 from both sides
2x= 650divide both sides by 2
x= 325 adult tickets
x + 75= 400 student tickets
ANSWER: There were 325 adult tickets sold

Answer:
a.) .0469
b.) .9961
c.) .9492
Rounded these check below for full answers
Step-by-step explanation:
a.)

b.)
Porbability of at most 3 successes is equal to 1-p(4)
p(4)=

1-.003690625=.99609375
c.)
two or more failures is equa lto
p(0)+p(1)+p(2)=

So you just have to subtract 15 - 7.5 = 7.5
because 7 x 2=14
and .5 +.5 = 1
and 14 + 1= 15
The answer to 7 3/4 divided by 4 is 1.9375
