Chenoa starts with $250 in her saving account and each month she adds $15 in her saving account.
Therefore, we obtain a sequence as:
250, (250+15), (250+15+15),...
250, 265, 280,....
So, we get the first term (
) as 250.
Now , we can clearly observe that the first term is 250 and second term is obtained by adding 15 to the first term that is 265 and so on.
Similarly in an arithmetic progression, last term is 
and its previous term is 
.
Similarly, will be obtained by adding 15 to its previous term .
So, 
and =250.
Therefore, Option C is correct.
Answer:
B
Step-by-step explanation:
12.25 times 11 is 134.75
488 times 0.21 is 102.48
134.75 plus 102.48 equals 237.23
237.23 is closest to 232 which is B.
Answer:
d. negative correlation
Step-by-step explanation:
Two variables are positive correlated when one goes up or down the other goes in the same direction and they are negative correlated when one goes up or down the other variable goes in the other direction.
In this case, the higher the temperature rises, the less snow. Therefore we have a negative correlation
Answer:
if you want in terms of π, then 3π
if you want it without π, then 9.42
Step-by-step explanation:
plug into formula
3= diameter
c=πd
c=π*3
3π or
π=3.14
so 3.14*3, which is 9.42
