Answer: in explination
Step-by-step explanation:
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
it will take 20 years
to check if you are right you would...
Check:
simple interest on $4000 for 20 years at 5%
= .05(20)(4000) = 4000
the amount = what we had + new amount
= 4000 + 4000 = 8000 which is double what we started with
So the answer would be it took 20 years.

Answer:
1/13
Step-by-step explanation:
I'm assuming you need the probability of choosing a 7 when pulling one card from a standard deck of playing cards.
There are four 7's in a deck of 52 cards.
Probability = (number of desired outcomes)/(number of possible outcomes)
The number of desired outcomes is 4 because there are 4 chances of pulling a 7 from a deck when choosing one card.
The total number of possible outcomes is 52 because there are 52 different cards to choose from when choosing one card.
So the probability is
P(7) = 4/52
P(7) = 1/13
