The answer would be a positive 15.1 or +15.1 because the positive number is greater than the negative which would make your answer positive, thats why you got it wrong :)

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.

Find the equation of the line passing through(1,2) and making an angle of 30 degree with y intercept

olya-2409 [2.1K]

Answer:

Equation of the straight line passing through the point ( 1,2 ) and having the slope

x - √3y -1+2√3 =0

Step-by-step explanation:

Step(i):-

Given that the point (1,2) and an angle = ∝ = 30°

The slope of the line

m = tan 30°

$m = \frac{1}{\sqrt{3} } }$

Step(ii):-

Equation of the straight line passing through the point ( 1,2 ) and having the slope

$m = \frac{1}{\sqrt{3} } }$

y - y₁ = m(x-x₁)

y - 2 = $\frac{1}{\sqrt{3} } }$ ( x -1)

√3(y-2) = (x-1)

⇒ √3y - 2√3 = x -1

x - √3y -1+2√3 =0

How would you convert the repeating, non terminating decimal into a fraction? Explain the process as you solve the problem 0.151

lorasvet [3.4K]

Divide 1515 by 100 and you would get 15.15 the divide the .15 by 3 and and you will get 3.5 so the answer will be 15 3/5

Anton [14]

Answer: 30 students.

Step-by-step explanation: They are saying 50% of the class like the teacher. We know that 50% is half of the 100% so that mean only half of the students like the teacher. Is 15 students like the teacher it means that 15 are half of the students in the class. The other half should be another 15. So 15+15=30 or 15x2=30.

I hope I didn’t make it to confusing.
