If the outliers were included in the data, the box plot would be significantly skewed.

Step-by-step explanation:

Outliers are the extreme values of the data.
mean is averaging it tries to balance between extreme values.
Median is mid-point of data.
Skewness it the distribution of data Symmetric mean=median=mean.
Asymmetric is extreme values distribute the data either right or left.
If mean is less then median it is left skewed, if mean is greater then median it is right skewed.
Whiskers show the range of the data.

The value of a collectible toy is increasing exponentially. The two points on the graph

shtirl [24]

The question is incomplete. Here is the complete question.

Part A

The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.

Express the toy's value t, in dollars, as a function of time w in weeks after purchase.

Part B

Write an expression to represent the toy's value 10 days after purchase

Answer and Step-by-step explanation: An exponential function is of the form: $y=ab^{x}$

<u>Part</u> <u>A</u>

Translating to the question, the toy's value as a function of time is

$t=ab^{w}$

To determine constants a and b, we use points given by graph.

First, (0,5) to find a:

$5=a.b^{0}$

a = 5

Now, (3,10) to determine b:

$10=5b^{3}$

$b=\sqrt[3]{2}$

b = 1.26

The toy's value as a function of time in weeks is $t=5.(1.26)^{w}$

<u>Part</u> <u>B</u>

Since, the function is in weeks:

1 week = 7 days

w weeks = 10 days

$w = \frac{10}{7}$

Replacing w:

$t=5.(1.26)^{w}$

$t=5.(1.26)^{10/7}$

Expression that represents toy's value after 10 days is $t=5.(1.26)^{10/7}$ .

Can someone help me with this, It's a bit confusing for me?

daser333 [38]

Step-by-step explanation:

use the Pythagoras theorem

a^2 + b^2 = c^2

35^2 + 12^2 = c^2

1369 = c^2

c = 37

Which no. is greater and by how much 3^3+9 or 2×10^2

motikmotik

2x10^2 is greater because it’s going to equal 200 and 3^3 +9 only equals 36 and by how much it would be 164!

Uhhh I am struggling with this question algebra 1

Olin [163]

Answer:

-2x^2 +16x -8

Step-by-step explanation:

Oh s-

Like terms i guess Same variable you can substract. Remember you only substract from 1 number not from all.

-2x^2 stays the same as there is no like term

9x - (-7x)

-2 - (6)

-2x^2 + 9x+ 7x -2-6

-2x^2 +16x -8
