Does this set of ordered pairs represent a function? Why or why not ?

Answer:

C. Yes, because every x-value corresponds to exactly one y-value

Step-by-step explanation:

We are asked to find whether the given ordered pairs represent a function or not.

\{(-1,5),(0,-3),(2,7)(4,0),(7,5)\}

We know that a relation is a function, when each input of x value gives exactly one output of y-value.

In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.

We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

We need more details to answer.  You did forget to mark ST as 16 but I see no problem with the NQ.  NQ should be self-similar to SU.

Thats about 9:12.  She should have enough information for them to be self-similar because you can find angle S by adding angle T and U together and subtracting 180 by the sum of those numbers.

I am not sure what the question is asking though specifically so can you provide more info

Using the binomial distribution, it is found that there is a 0.7447 = 74.47% probability that fewer than 7 of them show up.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

In this problem, the values of the parameters are given as follows:

p = 0.7, n = 8.

The probability that fewer than 7 of them show up is given by:

[tec]P(X < 7) = 1 - P(X \geq 7)[/tex]

In which:

P(X \geq 7) = P(X = 7) + P(X = 8)

Then:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 7) = C_{8,7}.(0.7)^{7}.(0.3)^{1} = 0.1977

P(X = 8) = C_{8,8}.(0.7)^{8}.(0.3)^{0} = 0.0576

Then:

P(X \geq 7) = P(X = 7) + P(X = 8) = 0.1977 + 0.0576 = 0.2553

[tec]P(X < 7) = 1 - P(X \geq 7) = 1 - 0.2553 = 0.7447[/tex]

0.7447 = 74.47% probability that fewer than 7 of them show up.
