Given:
p = 90% = 0.9, the probability that the seed grows into a healthy plant.
Therefore
q = 1 - p = 0.1, the probability that the seed will not grow into a healthy plant.
n = 7, the number of seeds planted.
Let r = 4, expected number of seeds that will grow.
Use the Binomial distribution to determine
P(4 of 7 seeds will grow) = ₇C₄ p⁴q⁽⁷⁻⁴)
= 35*(0.9⁴)*(0.1³)
= 0.023
P(4 of 7 seeds will not grow) = 1 - P(4 of 7 seeds will grow)
= 1 - 0.023
= 0.977 or 97.7%
Answer: 97.7%
<h3>
Answer: (-3, -6)</h3>
Explanation:
The notation tells us to add 6 to the x coordinate and subtract 4 from the y coordinate.
An equivalent notation would be to write
Point P has the x coordinate of -9. Adding on 6 gets us the new x coordinate of -9+6 = -3
It also has the y coordinate of -2. Subtract off 4 to get -2-4 = -6
So,
The given expression is . the option C is correct.

Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level
