Answer:
x = - , x = - 1
Step-by-step explanation:
Given
(x + 1)(3x + 4) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = -
Solutions from least to greatest are
x = - , x = - 1
Answer:
So, the probability is P=0.3087.
Step-by-step explanation:
We know that Priya's cat is pregnant with a litter of 5 kittens, so n=5.
Each kitten had a 30% chance of being chocolate brown.
We get that p=0.3 and q=1-0.3=0.7.
We calculate the probability that exactly 2 kittens will be chocolate brown, so k=2.
We use the formula:
we get
So, the probability is P=0.3087.
