if i put 1500 into my savings account and earned 180.00 of interest at 4% simple interest , how long was my money in the bank

tresset_1 [31]

T = ?

i = 180.00

R = 4% ; 4/100 => 0.04

p = 1500

i = p x R x t

180.00 = 1500 x 0.04 x t

180.00 = 60 x t

t = 180.00 / 60

t = 3 years

hope this helps!

A) what is the probability that the first contestant is a boy?

tamaranim1 [39]

Probabilities are used to determine the chances of an event.

The probability that the first contestant is a boy is 1/2
The probability that the second contestant is a boy, if the first is a boy is 9/19
The probabilities are not independent

The given parameters are:

$\mathbf{Contestants= 20}$

$\mathbf{Girls= 10}$

$\mathbf{Boys = 10}$

<u>(a) Probability that first contestant is a boy</u>

This is calculated as:

$\mathbf{P(Boy) = \frac{Boys}{Contestants}}$

This gives

$\mathbf{P(Boy) = \frac{10}{20}}$

$\mathbf{P(Boy) = \frac{1}{2}}$

<u>(b) Probability that the second contestant is a boy, if the first is a boy</u>

This is calculated as:

$\mathbf{P(Boy) = \frac{Boys - 1}{Contestants - 1}}$

We subtracted 1, because the first contestant (a boy) is no longer part of the selection.

So, we have:

$\mathbf{P(Boy) = \frac{10-1}{20-1}}$

$\mathbf{P(Boy) = \frac{9}{19}}$

<u>(c) Independent probabilities</u>

The probabilities are not independent, because when a contestant is selected, the number of contestant is reduced by 1.

And this will affect the probability of the next selection.

The auto parts department of an automotive dealership sends out a mean of 4.34.3 special orders daily. What is the probability t

Svetlanka [38]

Answer:

$P(X = 5) = 0.166$

Step-by-step explanation:

Given

$Mean = 4.3$

$x = 5$

Required

Determine the probability that the order is 5

This question can be answered using Poisson distribution.

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

Where

$\alpha$ is used to represent the mean

and

$\alpha = 4.3$

$x = 5$

<em /> $e = 2.71828$ <em> ---- Euler's constant</em>

So, we have:

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

$P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{5!}$

$P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{5* 4 * 3 * 2 *1}$

$P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{120}$

$P(X = 5) = \frac{1470.08443 * 0.01356859825}{120}$

$P(X = 5) = \frac{19.9469850243}{120}$

$P(X = 5) = 0.1662248752$

$P(X = 5) = 0.166$ <em>Approximated</em>
