Answer:
<em>P= 0.0606 = 60.6%</em>
Step-by-step explanation:
<u>Binomial Distribution
</u>
The required probability will be calculated by using the Binomial Distribution with n=385 independent events each with a probability of success equal to p=0.0362 with k=8 or fewer successes.
The PMF (Probability Mass Function) for the Binomial Distribution is
Where
We need to compute a range of probabilities from k=8 to k=0. We'll show how to compute for k=8
When the probability is cumulative and a high number of calculations need to be performed, we use automated tools (like Excel, digital calculator, etc) to compute the sum. We used Excel's BINOMDIST(8, 385, 0.0362, 1) function to get the total probability to get
The answer to the image is 41.8%.
Hope this helps.
Answer:
Given the following information, your system of equation is going to be...
x + y = 250
15x + 20y = 4250
Step-by-step explanation:
So, in the problem, we are given important key details that can help us solve it.
- x = number of $15 packages sold
- y = number of $20 packages sold
- The school collected $4250 from sales
- 250 packages were sold in total
Now that we have this information, we can solve the problem. Since 250 packages were sold in total, then you are going to add x and y. Since the school collected $4250 from the sales, then you are going to be adding 15x and 20y together.
So, to conclude, your answer is going to be the first answer choice.
Answer:
52+169
Step-by-step explanation:
First you multiply the 13, on the outside, with the 4.
Then you multiply the 13 with the other 13.
13*4=52
13*13=169
