In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.
Answer:
19% of households have more cars than the garage can hold
Step-by-step explanation:
We are given the following distribution for the number of cars owned by a family.
Number of cars X: 0 1 2 3 4 5 6
Probability: 0.07 0.31 0.43 0.12 0.04 0.02 0.01
We have to find the percentage of households have more cars than the garage can hold.
A garage can hold two cars. Thus, the household with more than two cars are the households that have more cars than the garage can hold.
The given distribution is a discrete probability distribution.
Thus, we evaluate:
Thus, 19% of households have more cars than the garage can hold.

Good evening!
In this question, we were asked to solve for the sales tax of the laptop that Youlanda bought.
We were given:
- Cost of laptop: $459
- Sales Tax: 7.5%
In order to find the amount Youlanda paid for the sales tax, we would multiply the cost of the laptop ($459) by the sales tax (0.075):
Calculate:
459 × 0.075 = 34.425
Your answer would be: $34.425
Step-by-step explanation:
∑ (4ⁿ⁺¹ / 5ⁿ)
Rewrite 4ⁿ⁺¹ as 4 (4ⁿ).
∑ 4 (4ⁿ / 5ⁿ)
∑ 4 (4/5)ⁿ
This is a geometric series. The sum of an infinite geometric series is:
S = a / (1 −r)
where a is the first term and r is the common ratio.
Here, the first term is 16/5 (because n starts at 1), and the common ratio is 4/5.
S = 16/5 / (1−4/5)
S = 16/5 / (1/5)
S = 16
