Given: Mean temperature μ = 24 , standard deviation σ =4
The lower and upper bound for temperature within one standard deviation of the mean is given by,
Lower bound = μ - σ = 24 - 4
Lower bound = 20
Upper bound = μ + σ = 24+ 4
Upper bound = 28
The temperature value between (20, 28) is said to be within one standard deviation of the mean.
From given option 27° lies in between (20°, 28°), hence 27° is the temperature value that is within one standard deviation of mean.
Answer:
The answer to your question is Area = 39.15 in²
Step-by-step explanation:
Data
See the picture below
Process
1.- Calculate the area of rectangle 1
Area = base x height
Area = (8.8)(6.55 - 4.3)
Area = (8.8)(2.25)
Area = 19.8 in²
2.- Calculate the area of rectangle 2
Area = (4.3)(2.25)
Area = 9.675 in²
3.- Calculate the area of rectangle 3
Area = (4.3)(2.25)
Area = 9.675 in²
4.- Calculate the total area
Area = 19.8 + 9.675 + 9.675
Area = 39.15 in²
Second way
Area 1 = 2[6.55 x 2.25]
Area 1 = 29.475 in²
Area 2 = (8.8 - 2.25 - 2.25)(6.55 - 4.3)
Area 2 = 4.3 x 2.25
Area 2 = 9.675 in²
Total area = 29.475 + 9.675
= 39.15 in²
Third way
Area 1 = (8.8 - 2.25)(6.55 - 4.3)
= (6.55)(2.25)
= 14.7375 in²
Area 2 = (4.3)(2.25)
= 9.675 in²
Area 3 = (6.55)(2.25)
= 14.7375 in²
Total area = 14.7375 + 9.675 + 14.7375
= 39.15 in²
There are some calculator shortcuts that can be used on a Windows OS and they are:
- Ctrl + R (recall from memory)
- Ctrl + L (erase memory)
<h3>What is a Calculator?</h3>
This refers to the mathematical tool that is used to make scientific calculations to find an expected result and is fully automated.
Hence, we can see that calculator shortcuts in a Windows OS exists and some of them include the combination of keys on a keyboard for quick actions such as clearing and recalling from memory, among many others.
