Answer:

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

Gnoma [55]

Answer:

Equation: $20=4x$ or $x=\frac{20}{4}$

Solution: $x=5$

Step-by-step explanation:

The formula that is used to calculate the perimeter of a square is:

$P=4s$

Where "s" is the side lenght the square.

Knowing that Xin used 20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

$P=20\\\\s=x$
