The domain of a relation is all the x - values the relation can take, so:

domain = {-8, -6, 5}

The range, in addition, is all the y - values the relation can take, so:

range = {-3, -1, 0, 5}

Please help i will give brainliest!!!

D) (-2,3)

-2 is the x-value
3 is the y-value

If you look at the graph on the x-axis (horizontal line) the numbers are increasing and decreasing by 1.
Since the point of intersection (big blue dot) is on the left side of 0, it falls directly at the -2 mark
As for the y-axis (vertical lines) the numbers also increase and decrease by 1. The point of intersection falls above 0 at +3

Therefore your point of intersection is (-2,3)

An instructor believes the distribution of scores on her final exam will have mean 62 and standard deviation 7. Fred is a studen
OLga [1]

Answer:

a) P(47

And then the probability that Fred will not score between 47 and 77 is

1-0.968 = 0.0321

b) P(45

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Part a

Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:

X \sim N(62,7)  

Where \mu=62 and \sigma=7

We are interested on this probability  on the probability that Fred will not score between 47 and 77. So we can begin finding this probability

P(47

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(47

And we can find this probability on this way:

P(-2.143

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2.143

And then the probability that Fred will not score between 47 and 77 is

1-0.968 = 0.0321

Part b

P(45

And we can find this probability on this way:

P(-2.429

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2.429
