You'd need to start by finding what 40% of 280 is. To do this, you turn 40% into a decimal which is .40 . Multiply .40 x 280 which is 112. Then subtract that answer from 280 which is 168 baseball cards. Hope this helped :)
Answer:
- Interests charged for 4 years: $80
- Total amount to pay back:$480
Step-by-step explanation:
- To know the future value of an specific amount that is borrowed from a bank we use the following equation:
, where FV is future value, PV present value, n the amount of periods and i the interest rate. - In this particular case, the present value of the loan is $400, n=4 (4 years), i=5%. Then the future value equals:
. Then FV= $480, which is the total amount of money she would have to return in 4 years. - The interest paid can be calculated as the total amount paid ($480) minus the inicial loan ($400), which means that total interests paid= FV- PV= $80.
Answer: x^2+4
Step-by-step explanation:
<span>There are 5 boxes, where we have to put given numbers. Addition of 5 odd numbers always gives an odd number result. 30 is an even number. So there is no combination of given numbers which can give you 30 as a result.

Answer:
0.2709
Step-by-step explanation:
Given that:
Average time between accidents (λ) = 7 weeks
Probability that more than 8weeks pass between accidents
P(x > 8) = 1 - P(x ≤8)
P(x > 8) = 1 - [p(0) + p(1) + p(2) + p(3) + p(4) + p(5) + p(6) + p(7) + p(8)]
To save computation time :
We can use a poisson distribution calculator :
Hence,
P(x > 8) = 1 - P(x ≤8)
P(x ≤8) = 0.72909
P(x > 8) = 1 - 0.72909
P(x > 8) = 0.2709
