Answer:
P(X ≤ 5) = 0.84134
Step-by-step explanation:
This is a normal distribution problem with
μ = mean = 4 years
σ = standard deviation = 1 year
To find the probability that a terminal will last 5 years or less using excel, we follow these steps. P(X ≤ 5)
- Use an empty cell.
- Right click and go to “Insert Formula”.
- In the searchbox, type “Normdist” and click “Go.”
- Pick “NORMDIST” from the list and then click “OK” to open the Function Arguments window.
- Enter the data into the box. Type “5” in the X box, “4” in the Mean box, “1” in the Standard Deviation box and “true” in the cumulative box..
- Click “OK.”. This returns 0.84134474 in the cell you clicked in Step 1, which is the probability that a terminal will last 5 years or less using excel, we follow these steps. P(X ≤ 5).
P(X ≤ 5) = 0.84134
Hi there!
Let's use x for the width because we know the width is only 1. Next, we'll use 5x for the length because the length is 5 times the width. Now, we can set up an equation to solve for x.
WORK:
x * 5x = 1620
5x^2 = 1620
x^2 = 324
x = 18
ANSWER:
The width of the rectangle is 18 centimeters
Hope this helps!! :)

➷ x + 1 = -10
- 1 from both sides to isolate x
x = -10 - 1
Solve:
x = -11
