Answer:
A
Step-by-step explanation:
This is a Bernoulli trial problem.
Since the probability that the seed will germinate is 80% or 0.8, the probability that they won’t germinate is 0.2
Now let’s say the probability to germinate is p and the probability not to is a, we can now set up the Bernoulli equation in this regard. Since we are proposing that exactly 14 will germinate, it means 6 are not expected to germinate
P(14) = 20C14 (0.8)^14 (0.2)^6 = 0.109099700973
Option A is the right answer
(4-4x)(x-3)
4x-12-(4x^2)+12x
(-4x^2)+16x-12=(pxq)(x)
Answer:
8 gallons
Step-by-step explanation:
#1: Set up a ratio from the recipe: gallons of punch to the number of people.
2 gallons 15 people
#2: Set up a ratio of gallons to the people coming to the party.
(Place the gallons on top) x gallons 60 people
#3: Set up a proportion 2 gallons x gallons
15 people = 60 people
* Like units should be across from each other
4) Solve using the "lonely mate" formula
2 gallons x gallons
15 people = 60 people
2 x 60 = 120
120/15 = 8
This means she should make 8 gallons.
The answer is 14. You would get x to the second power and 196. Then you have to square root both sides and you would get x=14.
Subtract them, just like you added:
4x + 10 - (-5x +20)
The minus turns (-5x + 20) into the opposite, or 5x - 20
4x + 10 + 5x - 20
9x - 10
I really hope this helps.
