Answer:
c
Step-by-step explanation:
The formula for volume of a cylinder is V = π
h. We replace r with the radius (to find it just divide the diameter by 2), which is 2.5. Hope this helped!! :]
The answer would be (5,-5) I think.
Answer:
y = -0.07x2 + 3.07x
Step-by-step explanation:
For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.
So, for 2 plants, we have (3 - 0.07) * 2
For 3 plants, we have (3 - 2*0.07) * 3
For x plants, we have (3 - (x-1)*0.07) * x
So we can model the final result of the amount of beans 'y' with the equation:
y = (3 - (x-1)*0.07) * x
y = (3 - 0.07x + 0.07) * x
y = (3.07 - 0.07x) * x
y = -0.07x2 + 3.07x
(In this equation we have a = -0.07, b = 3.07 and c = 0)
The answer 81pi is if it asked you to keep the answer in terms of pi.
The second answer is if they wanted pi calculated into the answer.
Using it's concept, it is found that there is a 0.875 = 87.5% probability that the player wins the match.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, these following outcomes result in the player winning the match:
- Wins the third set, with 0.5 probability.
- Loses the third set but wins the fourth, each with 0.5 probability.
- Loses the third and fourth sets but wins the fifth, each with 0.5 probability.
Hence, the probability that he wins the match is given as follows:
p = 0.5 + 0.5² + 0.5³ = 0.875.
