Given the set of test scores: 71, 75, 80, 81, 81, 84, 89, 93. If a score of 50 is added to the data set, which statement is true? Select all that apply. Choose all that apply:
The mean decreases.

The median decreases.

The standard deviation increases.

The range increases.​

Answers

Answer:

The standard deviation increases, it's mean, medium and mode, if you put them in order and then go through and get your middle number it'll be 81.

If a score of 50 is added to the data set,

The standard deviation increases.

The range increases.​

What is mean?

"It is the average of all elements of the data set."

What is median?

"It is the middle number in a sorted list of numbers."

Formula to calculate the standard deviation:

[tex]SD=\sqrt{\frac{\sum{(x-M)^{2}} }{N} }[/tex]

where, SD is the population standard deviation

N : the size of the population

x : each value from the data

M : the mean of the data

Formula to calculate the range of the data:

range = maximum value - minimum value

For given situation,

Consider the original set of test scores: 71, 75, 80, 81, 81, 84, 89, 93

N = 8

range R = 93 - 71

⇒ R = 22

Mean M = (71 + 75 + 80 + 81 + 81 + 84 + 89 + 93)/8

⇒ M = 654/8

⇒ M = 81.75

Now, we find the median K

First we sort given data set: 71, 75, 80, 81, 81, 84, 89, 93

The middle numbers are 81 and 81

So, the median is the average of 81, 81

So, K = 81

Now, we calculate the standard deviation.

[tex]SD=\sqrt{\frac{[(71-81.75)^{2}+(75-81.75)^{2}+...+(89-81.75)^{2}+(93-81.75)^{2}] }{8} }[/tex]

⇒ SD = 6.61

Consider, the set of test scores with 50 added to the data set.

N = 9

range R = 93 - 50

⇒ R = 43

Mean M =  (71 + 75 + 80 + 81 + 50 + 81 + 84 + 89 + 93)/9

⇒ M = 704/9

⇒ M = 78.22

Now, we find the median K

First we sort given data set: 50, 71, 75, 80, 81, 81, 84, 89, 93

The middle number is 81.

So, the median is K = 81

Now, we calculate the standard deviation.

[tex]SD=\sqrt{\frac{[(71-81.75)^{2}+(75-81.75)^{2}+...+(50-81.75)^{2}+(93-81.75)^{2}] }{9} }[/tex]

⇒ SD = 11.76

So, we can observe that if a score of 50 is added to the data set, the correct statements are:

The standard deviation increases.

The range increases.​

Is 3(x + 1)2 = (3x + 3)2 an identity? Explain and show your reasoning.

Answers

Answer:

YES

Step-by-step explanation:

The equation, [tex] 3(x + 1)2 = (3x + 3)2 [/tex], would be an identity if the equation remains true regardless of the value of x we choose to plug in into the equation.

Let's find out if we would always get a true statement using different value of x.

✍️Substituting x = 1 into the equation:

[tex] 3(x + 1)2 = (3x + 3)2 [/tex]

[tex] 3(1 + 1)2 = (3(1) + 3)2 [/tex]

[tex] 3(2)2 = (3 + 3)2 [/tex]

[tex] 12 = 12 [/tex] (TRUE)

✍️Substituting x = 2 into the equation:

[tex] 3(x + 1)2 = (3x + 3)2 [/tex]

[tex] 3(2 + 1)2 = (3(2) + 3)2 [/tex]

[tex] 3(3)2 = (6 + 3)2 [/tex]

[tex] 18 = 18 [/tex] (TRUE)

✍️Substituting x = 3 into the equation:

[tex] 3(x + 1)2 = (3x + 3)2 [/tex]

[tex] 3(3 + 1)2 = (3(3) + 3)2 [/tex]

[tex] 3(4)2 = (9 + 3)2 [/tex]

[tex] 24 = 24 [/tex] (TRUE)

Therefore, we can conclude that the equation, [tex] 3(x + 1)2 = (3x + 3)2 [/tex], is an identity.

The New Population corresponds to 115%

(That is 100+15)

We want to find the population that corresponds to 100% that is the original population.

Which function describes the arithmetic sequence shown?
The sequence is : -1, 1, 3, 5, 7, 9, 11, 13

Answers

Answer:

The function [tex]a_n=2n-3[/tex] describes the arithmetic sequence.

Step-by-step explanation:

Given the sequence

-1, 1, 3, 5, 7, 9, 11, 13

An arithmetic sequence has a constant difference 'd' is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

Compute the differences between all the adjacent terms:

[tex]1-\left(-1\right)=2,\:\quad \:3-1=2,\:\quad \:5-3=2,\:\quad \:7-5=2,\:\quad \:9-7=2,\:\quad \:11-9=2,\:\quad \:13-11=2[/tex]

As the difference between all of the adjacent terms is the same and equal to

[tex]d=2[/tex]

As the first element is

[tex]a_1=-1[/tex]

so the term will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=2\left(n-1\right)-1[/tex]

[tex]a_n=2n-3[/tex]

So, the function [tex]a_n=2n-3[/tex] describes the arithmetic sequence.
