Step-by-step explanation:
Percent error = |actual − theoretical| / actual × 100%
|42 − 30| / 42 × 100% = 28.6%
They bought 5 trophies total
1st trophy cost $37.50
($18.50+$12.50+$4+$2.50=$37.50)
Each additional trophy cost $15
($12.50+$2.50=$15)
They spent $97.50 total
$97.50-$37.50=$60
Additional trophies $15
$15*X=$60
4 trophies=$60+$37.50 for 1st trophy
$60+$37.50=$97.50
Answer:
60
Step-by-step explanation:
(This is not how teachers usually teach you)
First i divided 36 by 2 to get 30% = 18 then i multiplied 30% by 3.3333etc. to get 100% and i multiplied 18 by the same number (18*3.3333 = 60) and i got 60.
Answer:
f(1)=17
f(-2)=-7
Step-by-step explanation:
We are given that a function 
We have to evaluate f(1),f(-2) and 
Substitute x=1 in the given function then we get
f(1)=17
Substitute x=-2 in the given function then we get
f(-2)=-7
Substitute 
Then we get
