Answer:
The probability that no one in a family of five will be hospitalized in a year is 0,2373
Step-by-step explanation:
Let p denote the probability of being hospitalized during a year,
Then p=0.25
And p' the probability of not being hospitalized during a year is 1-p
Thus p' = 1-p = 1-0.25 = 0.75
The probability that no one in a family of five will be hospitalized in a year is equal to . That is
= ≈ 0,2373
Answer:
A
Step-by-step explanation:
given
16x² + 16xy + 4y²
an expression factorised as a perfect square has the form
(ax + by)²
= a²x² + 2abxy + b²y²
16x² + 16xy + 4y² ← is in this form
with a² = 16 , b² = 4
so a = = 4 and b = = 2
then 2ab = 2(4)(2) = 16
Thus
16x² + 16xy + 4y² = (4x + 2y)² ← in factorised form
