Suppose that 45% of people have dogs. If two people are randomly chosen, what is the probability that they both have a dog

mylen [45]

Answer:

$P(Dogs) = 0.2025$

Step-by-step explanation:

Given

$Proportion, p = 45\%$

Required

Probability of two people having dog

First, we have to convert the given parameter to decimal

$p = \frac{45}{100}$

$p = 0.45$

Let P(Dogs) represent the required probability;

This is calculated as thus;

P(Dogs) = Probability of first person having a dog * Probability of second person having a dog

$P(Dogs) = p * p$

$P(Dogs) = 0.45 * 0.45$

$P(Dogs) = 0.45^2$

$P(Dogs) = 0.2025$

Hence, the probability of 2 people having a dog is  $P(Dogs) = 0.2025$

If $400 is invested at the rate of 6% for one year, what will be the total value of the investment (the amount)?

viva [34]

Hmm... Let's see..

Alrighty: $400= 100% (the whole amount of money). 1% of that money= 400/100. If $400 invests once in one year, that is... 424 dollars.

Anyone out there who is looking for monthly payment, you invest 400 dollars with interest, the answer is 4934.22

Hope that helps ya!
