The probability that exactly 1 doesn't grow will be 0.07
<h3> What is Probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15
Using the Bernoulli approximation:
P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵
P(n=1)=9x0.15¹.⁵x0.8⁸.⁵
P(n=1)=0.07
Hence the probability that exactly 1 doesn't grow will be 0.07

Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is 
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
Answer:
The answer would be 7.5
Step-by-step explanation:
This is due to if there were to be a chart it would start at 15 then continue by 7.5 which would then lead to 1 hour which is 22.5 min additionally other people are not answering this because you did not give all the information such as the chart etc and the answers unlike me i have the toolds and the questions.
Answer:
Step-by-step explanation:
575 ÷ 100 x 28
= 161
= 28%
2/3. 5/6 1/2 any work I don't k ow of this is right but it's how I learned it
