Answer: the answer is c
Explanation:in general, the merges and splits in hierarchical clustering are determined in a greedy manner
Answer:
Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/ etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.
Explanation:
- As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:
- Evaluate elements in parentheses.
- Evaluate 'ranges' ().
- Evaluate 'intersections' (empty spaces).
- Evaluate 'unions' (,).
- Perform negation (-).
- determine percentages (%).
- Perform exponentiation (^).
- Perform multiplication (*) and division (/), both are of equal precedence.
- Perform addition (+) and subtraction (-), both are of equal precedence.
- Evaluate text operators like (&).
- Perform comparisons like (=, <>, <=, >=).

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment
Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :
EMI
RFI
Explanation:
- EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
- During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
- EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
- Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
- The internal circuits of personal computers generate EM fields in the RF range.
Answer:
Is it related to technology and computers?
Answer:
Natural systems are already in place while man made systems were created by humans manipulating things in some way.
Explanation:
man made: human created
natural systems: existed without interference
