Ratling [72]

Are you saying that $1050 was the initial amount of money in the savings account? If so then you'd find 84% of 1050, which is 1050*.84. (.84 is the decimal version of 84%)

If the population of a country increases at a rate of 1.5% annually, and its current population is 430,000, how many years will

Alchen [17]

For this case we have an equation of the form:
$y = A * (b) ^ t
$
Where,
A: initial amount
b: growth rate
t: time in years.
Substituting values we have:
$y = 430000 * (1,015) ^ t
$
By the time the population is triple we have:
$3 * 430000 = 430000 * (1,015) ^ t
$
Rewriting we have:
$3 = (1,015) ^ t
$
Clearing t we have:
$t = log1.015 (3)

t = 73.78876233

t = 73 years$
Answer:
It will take for the population to triple about:
t = 73 years

The number of typing errors made by a typist has a Poisson distribution with an average of seven errors per page. If more than s

Aleks [24]

Answer:

0.599 is the probability that a randomly selected page does not need to be retyped.

Step-by-step explanation:

We are given the following in the question:

The number of typing errors made by a typist has a Poisson distribution.

$\lambda =7$

The probability is given by:

$P(X =k) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\ \lambda \text{ is the mean of the distribution}$

We have to find the probability that a randomly selected page does not need to be retyped

P(less than or equal to 7 mistakes in a page)

$P( x \leq 7) = P(x =1) + P(x=1) +...+ P(x=6) + P(x = 7)\\\\= \displaystyle\frac{7^0 e^{-7}}{0!} + \displaystyle\frac{7^1 e^{-7}}{1!} +...+ \displaystyle\frac{7^6 e^{-7}}{6!} + \displaystyle\frac{7^7 e^{-7}}{7!} \\\\= 0.59871\approx 0.599$

Thus, 0.599 is the probability that a randomly selected page does not need to be retyped.
