9 27
cross multiply (7*27=189) and divide (189/9=21)
M = 21
-10x+8 and 5x-4 is a possible combination. Those are both linear equations when added together will give you -5x+4
Answer:
There are
kilobytes in a Terabyte
Step-by-step explanation:
If one Terabyte is
bytes and one kilobyte is
bytes, then, by simple quotient we can find how many kilobytes are in one Terabyte:

Notice that in the numerator we have 40 factors of "2", while in the denominator we have 10 factors of "2". So we can cancel just 10 common in denominator and numerator and end up with 30 factors of "2" left in the numerator.
On can also use the "properties of exponents" to simplify exponents with the same base.
The value of

, and

of each data is shown in the diagram below
Group A
Mean =

Median = 49.5
Range =

Interquartile Range =

Group B
Mean =

Median = 50
Range = 62-40=22
Interquartile range = 58.5-42 = 16.5
Correct statement: the time in Group B has a greater interquartile range
Angelica needs to sell 20 TVs.
Steps:
Step 1: You divide 5,000 and 250.
5,000/250 = 20
Check: You multiply 250 and 20.
250 x 20 = 5,000
