Step-by-step explanation:
sum of the arithmetic sequence
a1 = 8
a2 = a1 + 8 = 8+8 = 16
...
an = 8×n
the sum of the first n elements of such a series is
n/2 × (2×a1 + (n - 1)×d]
with d being the difference between 2 consecutive elements (= the added constant).
so,
s30 = 30/2 × (2×8 + 29×8) = 15×(31×8) = 3720
Answer:
No
Step-by-step explanation:
Answer:
Jean paid $2,286 for the snow thrower, with a finance charge of $306.
Step-by-step explanation:
Given that Jean bought a $ 1,980 snow thrower through an initial payment of 10% of the initial value, and 18 monthly payments of $ 116, to determine the final price paid by Jean, the following calculation is required:
(1,980 x 0.1) + (18 x 116) = X
198 + 2,088 = X
2,286 = X
Therefore, the final price paid for Jean was $ 2,286.
In turn, the finance charge arises from the difference between the final price and the list price, that is:
2,286 - 1,980 = X
306 = X
Thus, the finance charge is $ 306.
Sorry but u should write ur expression so i can solve it....
The theorical probability is 1/4, because there are 4 possible outcome, and they are equally likely to be picked (the sectors have the same area)
The experimental probability is 3/20, becuase the red sector was picked 3 times in 20 trials.
