The key features of polynomials are the vertex, axis of symmetry, x and y intercepts.

<span>1. </span>The degree will help you find the end behavior.

<span>2. </span>The vertex shows you where it changes concavity.

<span>3. </span>X and y intercepts give you a couple of points of reference.

<span>4. </span>Axis of symmetry is only applicable to even degree polynomials.

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

Write 7:30 in two ways

Aloiza [94]

Three ways are:

<u>In Fraction Form:</u> $\frac{7}{30}$
<u>In Ratio its</u>: What you said 7:30

And

In a Percent Form Its: 0.23- %
(I got that from dividing 7 by 30.)

Hope IT helped You. :D

The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.

<u>Interquartile Range: </u>

Given the Data -> First Quartile = 2, Third Quartile = 5

Interquartile Range = 5 - 2 = 3

<u>Range:</u> 8 - 1 = 7

<u>Variance: </u>

We start by determining the mean,

$\:1+\:2+\:3+\:3+\:3+\:5+\:8 / 7 = 3.57$

n = number of numbers in the set

Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.

$\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n-1},\\\\=> SS/n - 1\\\\=> 31.714/7 - 1\\=> 5.28571$

5.3

<u>Standard Deviation</u>

We take the square root of the variance,

$\sqrt{5.28571} = 2.29906$

2.3

If you are not familiar with variance and standard deviation, just leave it.

Janice needs at least $125 to buy a new bike. She already has $35 and plans to save $10 every week. If w represents the number o

Vilka [71]

Answer:

10w + 35 >= 125

Step-by-step explanation:

She saves $10m per week. That is 10w.

She already has $35, so add 35 to 10w.

10w + 35 >= 125
