Which relation is a function?

sergejj [24]

To determine which relation is a function, we can perform something called the vertical line test. We cover the graph in repeating vertical lines and if one vertical line connects with more than one point of the relation, the relation is not a function.

The relation in the bottom right corner is the only relation that passes the vertical line test.

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.

Evaluate the expression 42+6⋅52−33÷32

mote1985 [20]

The first step to solve this is to multiply the numbers
42 + 312 - 33 ÷ 32
then divide the numbers
42 + 312 - 1.03125
use the addition and subtraction rules to calculate the expression
352.96875
this means that the correct answer to your question will be 352.96875.

guajiro [1.7K]

Answer:

The mass of cocoa in chocolate candy is 3 g.

Step-by-step explanation:

30gr chocolate candy, mark on its packaging that it contains 10% cocoa, how many grams of cocoa does this represent?

mass of chocolate candy = 30 g

cocoa contains = 10 %

Now the mass of cocoa = 10 % of 30 g = 0.1 x 30 = 3 g

Mass of cocoa in the candy is 3 g.
