Answer:
Hi!
The answer to:
a. 6 bits.
b. 9 bits.
c. 26 bits.
Explanation:
a. For the states of the U.S.A, you need 50 or more combinations to represents each element.
<u>If you use 6 bits, the possible combinations are 2⁶ = 64. </u>
b. For days in a year, you need 365 or more combinations to represents each element.
<u>If you use 9 bits, the possible combinations are 2⁹ = 512.
</u>
c. For inhabitants of California, you need 36,457,549 or more combinations to represents each element.
<u>If you use 26 bits, the possible combinations are 2²⁶ = 67,108,864.</u> If you use 25 bits instead of 26, then you have 2²⁵ = 33,554,432 combinations. These possible combinations are not enough to represent each inhabitant.
Answer:
Data modeling occurs at three levels—physical, logical, and conceptual.
- A physical model is a schema or framework for how data is physically stored in a database.
- A conceptual model identifies the high-level, user view of data.
- A logical data model sits between the physical and conceptual levels and allows for the logical representation of data to be separate from its physical storage.
Answer:
weightPound = float(input("Enter your weight in pounds "))
heightInches = float(input("Enter your height in inches "))
weightKg = weightPound*0.453592
heightMeter = heightInches*0.0254
BodyMassIndex = weightKg/(heightMeter*heightMeter)
print("")
print("Your Weight in kilograms is: ")
print(weightKg)
print("Your Height in meters is: ")
print(heightMeter)
print("Your Body Mass Index is: ")
print(BodyMassIndex)
Explanation:
- Above is a Python Script to accomplish the task
- See attached image for the program output.
- Observe that we used the formula weight/height*height to calculate the Body Mass Index
- Observe also the conversion from pounds to Kilogram and inches to meters
Distance from the router, as well as floors, walls, and large metal objects between a device and the router can interfere with wireless connectivity. Piggybacking, if you fail to secure your wireless network, anyone with a wireless-enabled computer in range of your access point can use your connection. Network congestion, Routers or other network equipment are overloaded with too much traffic. Speed Mismatch. This occurs when multiple users try to make use of the same server. I could go on and on.
Hope this helps!
