Let x = discount rate
Equate:
$80(1-x) = $60
Solve for x:
1-x = 60/80
1-x = 3/4
x = 1 - 3/4
x = 1/4 or 0.25
x = 25%
Answer: is this high school
Step-by-step explanation:
Answer:
Mean = Sum of Values ÷ Total number of Values
Step-by-step explanation:
= 15+5+16+9+14+3+4+18+10+4 ÷ 10
= 98 ÷ 10
= 9.8 (Decimal point moves 1 place to the left when divided by 10)
divide by three on both.7/9
In all cases, if 
has real coefficients, then any complex roots occur in conjugate pairs, so if 
is a root, then so is 
. Also, by the fundamental theorem of algebra, if 
are roots to , then for some constant 
,
1. If 
and 
, then
Given that 
, we have
2.
With 
, we have
The rest are done in the same exact way.
