Evaluando una ecuación exponencial, veremos que luego de 5 años el capital se convierte en $12,884.08
<h3>¿En cuánto se convierte el capital?</h3>
Esta situación se podra modelar con la ecuación exponencial:
f(n) = $8,000*(1 + 10%/100%)ⁿ
Donde n es el número de años.
Podemos simplificar la ecuación para obtener:
f(n) = $8,000*(1.1)ⁿ
Ahora queremos ver el valor que toma esto cuando n = 5, asi obtenemos:
f(n) = $8,000*(1.1)⁵ = $12,884.08
Así que luego de 5 años, el capital se convierte en $12,884.08.

You can clearly eliminate 0.79d as an answer, because that is less than the amount that Ron's class donated. The last answer is also incorrect, because it states that Danny's class donated 21 more cents than Ron's class. The problem says that Danny's class donated 21% more than Ron's. The only way that d + 0.21 would be correct is if Ron's class donated $1. The problem does not say that. Therefore, we are left with two possibilities. The first choice is the correct one. Why?
21% more than Ron's class' donation would be the amount that Ron's class donated + an additional 21%. If Ron's class donated d dollars, then an additional 21% would be 0.21 * d = 0.21d. Hence, Danny's class donated a total of:
d + 0.21d = d(1 + 0.21) = 1.21d
Answer:
part a) The rate per unit is decreasing by -0.00001.
Step-by-step explanation:
y2-y1
-------- = slope
x2-x1
So if you plug it into the calculator, you should get -0.00001.
pretty small number :D ...but remember it's out of thousands of units.
<em>Answer:264 students</em>
Step-by-step explanation:You have to add to get you answer.I'll show you how I got 264:
12+12=24
24+36=60
60+36=96
96+21=117
117+21=138
138+63=201
201+63=264
Your answer is: 264 students
Answer:
We should expect 25 generated digits in order to get a fifth "4"
Step-by-step explanation:
For each generated digit, there are only two possible outcomes. Either it is a four, or it is not. The probability of a digit being a 4 is independent of other digits. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
The expetcted number of trials to get r sucesses, with p probability, is given by:

Assume that the calculator will generate a "4" on any given attempt with probability 0.20.
This means that 
How many total generated digits should we expect in order to get a fifth "4"
This is E when r = 5. So

We should expect 25 generated digits in order to get a fifth "4"
