According to the Mortgage Bankers Association, 8% of U.S. mortgages were delinquent in 2011. A delinquent mortgage is one that h

shepuryov [24]

Answer:

The probability that exactly one of these mortgages is delinquent is 0.357.

Step-by-step explanation:

We are given that according to the Mortgage Bankers Association, 8% of U.S. mortgages were delinquent in 2011. A delinquent mortgage is one that has missed at least one payment but has not yet gone to foreclosure.

A random sample of eight mortgages was selected.

The above situation can be represented through Binomial distribution;

$P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....$

where, n = number of trials (samples) taken = 8 mortgages

r = number of success = exactly one

p = probability of success which in our question is % of U.S.

mortgages those were delinquent in 2011, i.e; 8%

LET X = Number of U.S. mortgages those were delinquent in 2011

So, it means X ~ $Binom(n=8, p=0.08)$

Now, Probability that exactly one of these mortgages is delinquent is given by = P(X = 1)

P(X = 1) = $\binom{8}{1}\times 0.08^{1} \times (1-0.08)^{8-1}$

= $8 \times 0.08 \times 0.92^{7}$

= 0.357

Hence, the probability that exactly one of these mortgages is delinquent is 0.357.

A woman made $45,000 during the first year of her new job at city hall. Each year she received a 10% raise. Find her total earni

kati45 [8]

Equation: 45000(1+.1)^6

Answer: 79720.25

Explanation:

This is a prime example of a Compound Interest Formula based question. Due to the fact the question states that the woman is getting a raise every year, we add one rather than subtracting one. Next we convert the 10% into a decimal form into 0.1 and from there since the time is all the same we wouldn’t need to divide anything out so we raise the equation to the sixth power and our final answer is $79720.25

Answer:

1 and 5

Step-by-step explanation:
