The amount of Jen’s monthly phone bill is normally

Mathematics
1 answer:
vredina [299]4 years ago
7 0

Answer:

P(19

And we can find this probability with this difference and using the normal standard distribution

P(-3

Step-by-step explanation:

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

X \sim N(55,12)  

Where \mu=55 and \sigma=12

We are interested on this probability

P(19

And we can use the z score formula given by:

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

Replacing the info we got:

P(19

And we can find this probability with this difference and using the normal standard distribution

P(-3

I need to graph -0.2x- 0.6y = 0.12
olga2289 [7]
This is under point slope intercept. so Ax+Bx=Cx. you can always change this to slope intercept which will be -.6y=.2x+.12 then give 1 a variable like 1 or 2 or something. then solve it, -.6y=.2+.12, -.6y=.32, y=-.53 so when x is 1, y is -.53. then make x 2 so -.6y=.52 so then when x is 2 y is -.86

What is the importance of polynomial functions and how this real life applications improve or contribute to the value of life
-Dominant- [34]

Answer:

<u><em>What is the importance of polynomial functions?</em></u>

<u><em> </em></u>Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.

<u><em>How these real-life applications improve or contribute to the value of life?</em></u>

Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
