Step 2 shows Emily's first mistake.
Step-by-step explanation:
3(2) = 6
But instead of this Emily wrote 3(2) = 9.

Answer:
8
Step-by-step explanation:
You can first simplify each fraction, so the it would be (24/10 + 44/5) - 16/5. And then add what is in the parenthesis, 556/5, and then subtract 16/5 to get 8.
Answer:
z = -3.73
Probability = P(z<-3.73) = 9.48761E.05
Step-by-step explanation:
Detailed explanation is given in the attached document.
The probability that the project will take more than 30 days to complete can be found using the NORMSDIST() function in Excel, and it depends on the z-score associated with the project's completion time distribution.
To find the probability that a project will take more than 30 days to complete using the normal distribution, you'll need to follow these steps:
1. Calculate the z-score for 30 days using the formula:
Z = (X - μ) / σ
Where:
- X is the value you're interested in (30 days in this case).
- μ is the mean completion time (expected completion time).
- σ is the standard deviation of completion times.
2. Once you have the z-score, use Excel's NORMSDIST() function to find the probability associated with that z-score.
Here's a hypothetical example of how to do this:
Let's say the expected completion time (mean) for the project is 25 days, and you have a standard deviation (σ) of 5 days. Now, calculate the z-score:
Z = (30 - 25) / 5
Z = 1
Now, use Excel's NORMSDIST() function to find the probability associated with a z-score of 1:
`=1 - NORMSDIST(1)`
This formula will give you the probability that the project will take more than 30 days to complete.
Make sure to replace the mean (25) and standard deviation (5) in the formula with the actual values from your project data. Additionally, round the z-score to two decimal places and the final answer to four decimal places, as requested in your question.

Complete Question
Let x be a continuous random variable that follows a normal distribution with a mean of 550 and a standard deviation of 75.
a
Find the value of x so that the area under the normal curve to the left of x is .0250.
b
Find the value of x so that the area under the normal curve to the right ot x is .9345.
Answer:
a
b
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
Generally the value of x so that the area under the normal curve to the left of x is 0.0250 is mathematically represented as
Generally the critical value of 0.0250 to the left is
