Answer: 0.0023
Step-by-step explanation:
Let X be the binomial variable that represents the number of receipts will show that the above three food items were ordered.
probability of success p = 32% = 0.32
Sample size : n= 10
Binomial probability function :
Now, the probability that eight receipts will show that the above three food items were ordered :
hence, the required probability = 0.0023
Minutes. Because you cannot concert minutes to hours.
1 hour= 60 Minutes
2 hours= 120 Minutes
Answer:
Step-by-step explanation:
a) The domain is R- all real numbers.
b) The domain is R- all real numbers.
c) we need
So the domain is R\{-2, 2}
d)
we need
So the domain is R\{-2, 1}
e)
we need: x-1>0 or x> 1
So the domain is (1,+∞)
Step-by-step explanation:
Did you mean:
= (a - b)(a + b)
= a.a + b.a - b.a - b.b
= a² + ba - ba - b²
= a² - b²
Answer:
Step-by-step explanation:
One solution would be (1, -4), and the other would be (4, -7).
