Answer: A) Very good on reads and D) Parity on separate disk
Explanation:
RAID-5 uses the disk striping with parity and it is a independent disk arrangement of the redundant array. As, the parity and data are placed in an even manner over the disk, in such a way that the bottleneck frame is not present in any disk.
In case of disk failure, the management of data can still be done with the help of stripping. Combination of parity and data stripping is one of the main advantage of RAID-5 and it is also very good in reading the data.
Answer:
import csv
def ideal_weight( filename ):
with open( "filename", "r" ) as file:
for row in csv.DictReader( file):
print ( "Name of person: ",row["name"] )
person_weight = ( 110 * row["height"] )/ 5
print ( "Ideal weight: ", person_weight )
Explanation:
The python source code above is a function which recieves a csv file argument, opens the file and reads each row an ordered dictionary. The function prints the name of each person in the file and their ideal weight.

Answer:
d. d1− = 10, d1+ = 0
Explanation:
Given
3X1 + 4X2 +d1− − d1+ = 36
X1 = 6
X2 = 2
Required
Possible values of d1- and d1+
We have:
3X1 + 4X2 +d1− − d1+ = 36
Substitute values for X1 and X2
3 *6 + 4 * 2 + d1- - d1+ = 36
18 + 8 + d1- - d1+ = 36
Collect like terms
d1- - d1+ = 36 - 18 - 8
d1- - d1+ = 10
For the above equation to be true, the following inequality must be true
d1- > d1+
Hence,
(d) is correct
Because:
10 > 0
