Answer:
No, although the random and large counts conditions are met, the 10% condition is not met.
Step-by-step explanation:
The random condition is met because the student selects a random sample of 50 seniors. The large counts condition is met because there are 38 expected successes and 12 expected failures, which are both at least 10. The 10% condition is not met because n = 50 is not less than 10% of the size of the population (N = 274 seniors).
Gg easy
remember
for
ax^2+bx+c=0
first
minus c from both sides
ax^2+bx=-c
divide both sides by a (disregard if a=1)
take 1/2 of b and square it and add that to both sides
factor perfect square
ok so
x^2-3x=-1
-3/2=-1.5
(-1.5)^2=2.25
add that to both sides
x^2-3x+2.25=2.25-1
factor
(x-1.5)^2=1.25
