Answer:
3
Step-by-step explanation:
Standard derivation is how much the data varies from the mean
class 2 has a lower derivation, the scores vary less from the mean, being closer
Answer:
100 - 75 = 25%
25%=119.60
need to find 1%
25/25=1%
119.60/25=1%
1%=4.784
now multiply by 100 to find original price
100% = 478.40
original price £478.40
It is 84.
x=100%
63=75%
(63*100)/75=84
Domain refers to all of the x-values that satisfy the line, and the range refers to all of the y-values that satisfy the line.
Since t corresponds to the x-ordinates, then the domain becomes:
0 ≤ t ≤ 6
and the range becomes:
0 ≤ v ≤ 150
In short, the answer is (A)
