Principle: $6500 Rate: 3%

Nikitich [7]

Answer:

Step-by-step explanation:

A)Initial amount deposited into the account is $6500 This means that the principal is P, so

P = 500

It was compounded daily. This means that it was compounded 360 times in a year. So

n = 360

The rate at which the principal was compounded is 3%. So

r = 3/100 = 0.03

It was compounded for 5 years. So

t = 5

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 6500 (1+0.03/360)^360×5

A = 6500 (1+0.00008333333)^360×5

A = 6500 (1.00008333333)^1800

A = $7551.70

B) The interest earned is Total amount earned - principal. It becomes

7551.7 - 6500 = $1051.7

sveta [45]

Answer:

13.53% probability that no earthquakes with a magnitude of 6.5 or greater strike the San Francisco Bay Area in the next 40 years

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

$e = 2.71828$ is the Euler number

$\mu$ is the mean in the given time interval.

According to geologists, the San Francisco Bay Area experiences five earthquakes with a magnitude of 6.5 or greater every 100 years.

One earthquake each 100/5 = 20 years.

What is the probability that no earthquakes with a magnitude of 6.5 or greater strike the San Francisco Bay Area in the next 40 years?

40 years, so $\mu = 40/20 = 2$

This probability is P(X = 0).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-2}*2^{0}}{(0)!} = 0.1353$

13.53% probability that no earthquakes with a magnitude of 6.5 or greater strike the San Francisco Bay Area in the next 40 years
