Knowing that a year later, the car is only worth 0.80 x, you can simplify that by stating that one year after purchase, the car is only worth 80% of its original purchase price.
Another way of stating that is that the car lost 20% of its value of the course of one year.
Answer:
RS: 26
ST: 40
Step-by-step explanation:
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 + 24 = 60 + 24
7x = 84
7x / 7 = 84 / 7
x = 12
---------------------------------------
RS
3x - 16
3 (12) - 16
36 - 16
20
---------------------------------------
ST
4x - 8
4 (12) - 8
48 - 8
40
----------------------------------------
RS + ST = RT
20 + 40 = RT
60 = RT
Answer:
Step-by-step explanation:
Solution:
AM =( X_1 + X_2 )/2
=( 18 + 2 )/2
=20/2
=10
Find Geometric mean for data 18,2
Solution:
GM =sqrt( X_1 × X_2 )
=sqrt( 18 × 2 )
=sqrt(36)
=6
Option a: 
is the right answer
Step-by-step explanation:
