The number of electoral votes each state is assigned is determined by the size of its population every ten years. The chart show

sattari [20]

Answer:

D. $Q_3=47$

Step-by-step explanation:

We have been given a table that represents the the number of electoral votes California was assigned each decade of the past century. We are asked to find the 3rd quartile of our given data.

The number of votes are: 9, 13, 13, 22, 25, 32, 40, 45, 47, 54, 55.

We will use upper quartile formula to solve our given problem.

$Q_3=\frac{3}{4}*(n+1)^{\text{th term}}$ , where, n represents the number of elements in the data set.

We can see that our data set has 11 data points, so upon substituting n=11 in above formula we will get,

$Q_3=\frac{3}{4}*(11+1)^{\text{th term}}$

$Q_3=\frac{3}{4}*(12)^{\text{th term}}$

$Q_3=3*3^{\text{th term}}$

$Q_3=9^{\text{th term}}$

Now let us count 9th term of our data set. Upon counting our data set from left to right we can see that 9th term of our data set is 47, therefore, 3rd quartile of our given data is 47 and option D is the correct choice.

What is the solution to the following equation?

nexus9112 [7]

Answer:

The answer to your question is the letter B. x = 6

Step-by-step explanation:

Data

4x² - 48x = -144

Process

1.- Equal to zero

4x² - 48x + 144 = 0

2.- Multiply 4 by 144

4 x 144 = 576

3.- Find the prime factors of 576

576 2

288 2

144 2

72 2

36 2

18 2

9 3

3 3

4.- Find two numbers that added gives -48,

these numbers are -24 and -24

5.- Write the equation using these numbers

4x² -24x - 24x + 144 = 0

6.- Factor by grouping

4x(x - 6) - 24(x - 6)

7.- Factor by like terms

(x - 6)(4x - 24)

8.- Find the solutions

x - 6 = 0 4x - 24 = 0

x = 6 4x = 24

x = 24/4

x = 6

What is an outlier mmkay

weeeeeb [17]

In statistics, an outlier is an observation point that is distant from other observations. These extreme values need not necessarily impact the model performance or accuracy, but when they do they are called “Influential” points. Note: An outlier is a data point that diverges from an overall pattern in a sample.
