Logan wants to move to a new city. He gathered graphs of temperatures for two different cities. Which statements about the data

sets shown are true?
City A

A box-and-whisker plot. The whiskers have a range of 10 and the box has a range of 3.

City B

A box-and-whisker plot. The whiskers have a range of 18.5 and the box has a range of 9.5.
City A is likely to have a colder temperatures because the interquartile range is smaller than that of City B.
City A is likely to have temperatures that remain fairly constant year round because it has a compact interquartile range compared to that of City B.
City A is likely to have very hot days and extreme temperatures because the mean is larger than that of City B.
City B is likely to have more warm days than City A because the maximum value is greater.
City B is likely to have more extreme temperatures with colder days in winter and hotter days in summer because the range is greater than that of A.
City B is likely to have more lower temperatures than City A because the median for City B is lower.

3x- 11 +59 = 90
3x + 48 = 90
3x +48-48 =90-48
3x = 42
3x/3 = 42/3
x= 14

<MNQ = 3x -11
<MNQ = 3(14)-11
<MNQ = 42-11

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%

<em>LET X = Number of U.S. mortgages those were delinquent in 2011</em>

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

<u><em>Hence, the probability that exactly one of these mortgages is delinquent is 0.357.</em></u>
