An outlier is a mathematical value in a set of data which is quite distinguishing from the other values.

Its more like outliers are values uncommonly far from the middle. Mostly, outliers have a significant impact on mean, but not on the median, or mode.

Hence making the outliers are crucial in their influence on the mean.

we can say that the outlier is a data point that lies outside the entire pattern in a distribution.

They are mostly shown as dots and its known that the whiskers are required to change. Whiskers stretch out to the farthest point in the data set that isn't an outlier.

{Question in English -

What is 2 + 2 +2 +3 +2+ +++2++ +2?}

Mean 4.9 letters and standard deviation 1.5 letters are best estimates of the population parameters . So, the correct option is (C)

The estimated mean of the sampling distribution is 4.9 letters, which is a good estimate of the population mean word length. The estimated standard deviation of the sampling distribution is 0.15 letter, which is the standard error of the mean.

The standard error of the mean is calculated by dividing the population standard deviation by the square root of the sample size. Since the sample size is 100 and the standard error is 0.15 letter, we can estimate the population standard deviation as follows:

population standard deviation = standard error x sqrt(sample size)

= 0.15 x sqrt(100)

= 1.5 letters

Therefore, the best estimates of the population parameters are:

Mean = 4.9 letters (same as the estimated mean of the sampling distribution)

Standard deviation = 1.5 letters

So, the correct option is (C) Mean 4.9 letters and standard deviation 1.5 letters.

In maths, A∩B refers to the intersection of two sets, A and B. This means that it includes all the elements that are in both sets A and B. For example, if A = {1, 2, 3, 4} and B = {3, 4, 5, 6}, then A∩B = {3, 4}, as these are the elements that are in both sets.

To find the intersection of two sets, you can list out all the elements in each set and then look for the ones that are in both. Alternatively, you can use a Venn diagram to visually represent the two sets and their intersection.

Here is an example using a Venn diagram:

A = {1, 2, 3, 4}
B = {3, 4, 5, 6}



As you can see, the intersection of A and B is the area where the two circles overlap, which includes the elements 3 and 4. Therefore, A∩B = {3, 4}.

Answer:

10 and 14

Step-by-step explanation:

let the 2 numbers be x and y , then

[tex]\frac{1}{2}[/tex] (x + y) = 12 ( multiply both sides by 2 to clear the fraction )

x + y = 24 ( subtract x from both sides )

y = 24 - x → (1)

and

[tex]\frac{1}{4}[/tex] xy = 35 ( multiply both sides by 4 )

xy = 140 → (2)

substitute y = 24 - x into (2)

x(24 - x) = 140

24x - x² = 140 ( subtract 140 from both sides )

24x - x² - 140 = 0 ( multiply through by - 1 and arrange in standard form )

x² - 24x + 140 = 0 ← in standard form

(x - 10)(x - 14) = 0 ← in factored form

equate each factor to zero and solve for x

x - 10 = 0 ⇒ x = 10

x - 14 = 0 ⇒ x = 14

corresponding values of y are by substituting values of x into (1)

x = 10 → y = 24 - 10 = 14

x = 14 → y = 24 - 14 = 10

then the numbers are 10 and 14

Answer:

(1, - 2 )

Step-by-step explanation:

9x - 3y = 15 → (1)

3x + 3y = - 3 → (2)

add (1) and (2) term by term to eliminate y

(9x + 3x) + (- 3y + 3y) = 15 - 3

12x + 0 = 12

12x = 12 ( divide both sides by 12 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (2)

3(1) + 3y = - 3

3 + 3y = - 3 ( subtract 3 from both sides )

3y = - 6 ( divide both sides by 3 )

y = - 2

solution is (1, - 2 )

we can conclude that 2.2 is less than 14/4.

what is fraction ?

A fraction is a mathematical representation of a part of a whole or a ratio between two quantities. It is typically represented as a top number (numerator) divided by a bottom number (denominator), separated by a horizontal line.

For example, the fraction 3/4 represents three parts out of four equal parts of a whole. The numerator (3) represents the number of parts, while the denominator (4) represents the total number of parts that make up the whole.

According to the question:
To compare 2.2 and 14/4, we can convert 14/4 to a decimal:

14/4 = 3.5

Now we can see that 2.2 is less than 3.5. Therefore, we can say that:

2.2 < 14/4

Another way to compare them is to convert both numbers to a common denominator. In this case, the common denominator of 2.2 and 14/4 is 10:

2.2 = 22/10

14/4 = 35/10

Now we can see that:

22/10 < 35/10

Therefore, we can conclude that 2.2 is less than 14/4.

Amy Folsom will need to make 64 trips to deliver 40 cords of wood with her small pickup truck.

To find the number of trips needed to deliver 40 cords of wood, we can use the following formula:

Number of trips = Total amount of wood / Amount of wood per trip

In this case, the total amount of wood is 40 cords and the amount of wood per trip is 5/8 cord.

Plugging these values into the formula, we get:

Number of trips = 40 / (5/8)

Number of trips = 40 * (8/5)

Number of trips = 64

The equation of the nth term is a(n) = 2-8n

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression.

The common difference = -14-(-6) = -14 +6 = -8

The first term is a1

The nth term of an arithmetic sequence =

a(n )= a1+(n-1)d

a(n) = a1+(n-1)-8

a(n )= a1-8n+8

if a1 = -6

a(n) = -6-8n +8

a(n) = 2-8n

Step-by-step explanation:

Mrs. Cook was able to make 60 sandwiches using 6 jars of jelly.

Mrs. Cook was able to make 60 sandwiches. To find the answer, we can use the following equation:

Total number of sandwiches = (Total amount of jelly) / (Amount of jelly used per sandwich)

In this case, the total amount of jelly is 6 jars, and the amount of jelly used per sandwich is 1/10 jar.

Plugging these values into the equation gives us: Total number of sandwiches = (6 jars) / (1/10 jar)

To solve this equation, we can multiply the numerator and denominator by 10 to get rid of the fraction:

Total number of sandwiches = (6 jars × 10) / (1/10 jar × 10)

Simplifying gives us: Total number of sandwiches = 60 jars / 1 jar

Finally, we can cancel out the "jars" units to get:

Total number of sandwiches = 60

Therefore, Mrs. Cook was able to make 60 sandwiches using 6 jars of jelly.
