The answer would be 93% because first we need to do the reverse of how to find the mean... 80 * 4 = 320 and so we just have to subtract the grades from 320... 320 - 79 - 66 - 82 = 93... Thus Jordan's grade was 93
-2(4w-1)=3(4w+2)
-8w+2=12w+6
-20w=4
w=-0.2
Cafeteria ratio of Swiss cheese to cheddar cheese is 15:17.
Perry’s ratio of Swiss chess to cheddar cheese is 5:7.
Wrong ratio because 5 * 3 = 15 but 7 * 3 does not equal 17.
Answer:
d.)
Step-by-step explanation:
Answer:
Explicit form: 
Recursive form: 
with 
.
Step-by-step explanation:
The first term is 3 and we are dividing by 3 each time.
Another way to say we are dividing by 3 each time is to say we are multiplying by factors of 1/3.
If the first term is 
and 
is the common ratio then the geometric sequence in explicit form is:
The recursive form for a geometric sequence is 
with 
where is the common ratio and is the first term.
So the recursive form for our sequence is with .
