Answer:

yes a function is being represented

Step-by-step explanation:

in order for a graph to represent a function, the graph of a function f is the set of ordered pairs, where f(x) = y. In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

The amount of Jen's monthly phone bill is normally distributed with a mean of $59 and a standard deviation of $10. What percenta
blsea [12.9K]

Answer:

P(29

And we can find this probability with this difference:

P(-3

And in order to find these probabilities using the normal standard distribution or excel and we got.  

P(-3

So we expect about 99.735% of values between $29 and $89

Step-by-step explanation:

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

X \sim N(59,10)  

Where \mu=59 and \sigma=10

We are interested on this probability first in order to find a %

P(29

The z score is given by:

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

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

P(29

And we can find this probability with this difference:

P(-3

And in order to find these probabilities using the normal standard distribution or excel and we got.  

P(-3

So we expect about 99.735% of values between $29 and $89

Herky found that 8 out of every 100 beans in his garden were nibbled by rabbits. How many beans can he expect to be damaged if t
jek_recluse [69]

Answer: 36 beans

Step-by-step explanation:

Make a proportion

For every 100 beans, 8 are damaged

8/100

For every 450 brand, x are damaged

x/450

Set the expressions equal to each other

8/100=x/450

100x=3600

Divide by 100 on both sides

x=36

So, out of 450 beans, 36 should be damaged

Hope this helped! :)

The difference of a positive integer and an integer that is greater than it
Kobotan [32]

Answer: Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, …. ... If an integer is greater than zero, we say that its sign is positive. If an integer is less than zero, we say that its sign is negative

so 8 9 10 is positive and -8 -9 -10 is negative

they cancel each other out like 8+-8 = 0 and -8+4=-4
