Select The Outlier In The Data Set.thenIf The Outlier Were Removed From The Data Set, Would The Mean

Answers

Answer 1
Answer:  Increase

====================================================

Explanation:

The set of given numbers sorts to this

11, 50, 72, 78, 80, 81, 85, 89, 94, 96, 97, 98

The majority or main cluster of the values are between 50 and 98. The outlier 11 is off on its own pretty far from the main cluster.

Let's find the mean of every value in this set. If you added up all the numbers, then you should get 931. Divide this over the number of values (12) and the mean of this set is roughly 931/12 = 77.5833

Now let's kick out the outlier 11. The 931 will drop to 931-11 = 920. Divide that new smaller sum over the 12-1 = 11 items left to get 920/11 = 83.6364 approximately.

--------------

To summarize so far:

old mean = 77.5833 approximatelynew mean (removed outlier) = 83.6364 approximately

We see that the mean has increased. This is because the outlier was pulling down on the mean to make it smaller than it should be. Once the outlier is out of the picture, the new mean will increase and better represent the center of the main cluster.

make x the subject of the following: k = 2(3x - 5)

Answers

Answer:

x = (k+10)/6

Step-by-step explanation:

k = 2(3x - 5)

Distribute the 2

k = 6x - 10

Add 10 to each side

k+10 = 6x-10+10

k+10 = 6x

Divide each side by 6

(k+10)/6 = 6x/6

(k+10)/6 = x

Answer:

x = (k + 10) / 6

Step-by-step explanation:

k = 2(3x - 5)

k = 6x - 10

k + 10 = 6x

What is the area of a rectangle whose side are x – 3 and x + 5?

Answers

Given :

The sides of a rectangle are (x - 3) and (x -5).

To Find :

The area of the rectangle.

Solution :-

Here we are given two sides of rectangle . We know that the area of rectangle is ,

→ Area = side 1 * side 2

Substituting the respective values ,

→ A = (x-3)(x+5)

→ A = x(x+5) -3(x+5)

→ A = x² + 5x -3x -15

A = +2x - 15

Hence the area of the rectangle is +2x -15.

Lucas is having yogurt and an apple for a snack. There are five containers of yogurt in the refrigerator: three are raspberry, one is vanilla, and one is peach. There are also two green apples and three red apples.

If he reaches into the refrigerator to get a yogurt without looking, what is the probability that Lucas will choose a raspberry yogurt?

What is the probability that he will choose a red apple if it is the first item he selects?

What is the probability that Lucas will eat a raspberry yogurt and a red apple?

Answers

Answer:

If Lucas reaches into the refrigerator to get a yogurt without looking, there is a 3/5 probability that Lucas will choose a raspberry yogurt.

There is a 3/5 probability that he will choose a red apple if it is the first item he selects.

There is a 9/25 probability that Lucas will eat a raspberry yogurt and a red apple.

Step-by-step explanation:

3/5 x 3/5 = 9/25

Answer:

Probability of yogurt being raspberry = 3/5 = 0.6Probability of choosing a red apple = 3/10 = 0.3Probability of raspberry yogurt AND red apple = 9/50 = 0.18

Step-by-step explanation:

Total of 5 yogurts: 3 raspberry + 1 vanilla + 1 peach

Probability of yogurt being raspberry = 3/5 = 0.6

Total of 5 apples: 2 green + 3 red

Total number of snacks = 10

Probability of choosing a red apple = 3/10 = 0.3

Probability of raspberry yogurt AND red apple = 0.6 x 0.3 = 9/50 = 0.18

A-n=1/4

B- n=1

C- n=3.26

D- n=-10.1

Answers

Answer:

B- n = 1

Step-by-step explanation:

"For all the positive integers n" is a qualifying statement. The number used has to be positive and also must be an integer. Integers are whole numbers and their opposites, so basically no fractions and no decimals. Answer A is a fraction and C is a decimal and D is negative and a decimal. So they don't work for this problem.

The value is n to show that the first step in a proof by mathematical induction of for all the positive integers is 1.

Thus, option B is correct.

The conditions can be checked through the options.

The option C and D will be eliminated because the condition is for all the positive integers n but n is decimal here.

For n = 1/4, the solution will be in fractions.

So, it does not hold true for n= 1/4.

For n = 1

[tex]\dfrac{n(n + 1)(2n + 1)}{6}[/tex]

 =[tex]\dfrac{1(1 + 1)(2 \times 1 + 1)}{6}[/tex]

= 1

Thus, the value is n  to show that the first step in a proof by mathematical induction of for all the positive integers n is 1.

So, option B is correct.

6 are boys, 18 are girls.

Answer:

Step-by-step explanation:

let x be the number of children in the class , then

number of boys = [tex]\frac{1}{4}[/tex] x , so

x = [tex]\frac{1}{4}[/tex] x + 18 ( multiply through by 4 to clear the fraction )

4x = x + 72 ( subtract x from both sides )

3x = 72 ( divide both sides by 3 )

x = 24

A girl's age in 12 years' time is the square

Answers

Answer: her present age is 4

Step-by-step explanation:

Proof: 4+12=16

Square root 4 is 16

Answer:

  4

Step-by-step explanation:

Let x represent her present age. The given relation is ...

  x +12 = x^2

Putting this in standard form, we can factor it:

  x^2 -x -12 = 0

  (x -4)(x +3) = 0

Solutions to this quadratic are x = 4, x = -3. The -3 solution is extraneous in this context.

Find the slope.
Find the slope

Answers

Answer:

-x + 1 __________________________

Answer:

-1

Step-by-step explanation:

The slope is the change in y over the change in x. In this graph, the y-value decreases by 1 unit to the right, and the x-value increases by 1 unit. So, this means that the slope is represented as -1/1. This can then be rewritten as -1.

We know that this slope is negative because it decreases to the right. Positive slopes increase to the right.

check the injectivity and subjectivity of the function:

[tex] \sf \large f:N \longmapsto \: N \: given \: by \: f(x) = x {}^{3} .[/tex]​

Answers

Answer:

The function is injective but nor surjective

Step-by-step explanation:

We see that:

f(x) = x³

For any x₁ and x₂ ∈ N,

f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbers

It it confirmed one-to-one, hence it is injective

Check the surjectivity:

f(x) = y ∈ N

x³ = yy = ∛x

Let y = 2, then:

2 = x³x = ∛2 ∉ N

Since x is not natural, the function is not surjective

Answer:

This function is injective only.

Step-by-step explanation:

N = natural numbers = positive whole numbers equal to or greater than 1.

Therefore [tex]N \rightarrow N[/tex] means that both the input and output are natural numbers.

A function is surjective if for every element in the codomain, there is at least one element in the domain.

Therefore, this function is NOT surjective.  For example, there is no natural number for x for which f(x) = 2.

A function is injective if for every element in the codomain, there is at most one element in the domain.  This is also called "One-to-One".

Therefore, this function IS injective as there is either none or only one value of x for each value in the codomain.

The mean number of calls for Sami is 2.25 calls per day and for Marta it is 2.5 calls per day

The person who made more calls per day is Marta.

What is the mean?

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Sami = 27 / 12 = 2.25 calls per day
