The mean and the median value of the given data set is 12.62 and 6.

According to the statement

We have to find that the mean and the median of the following data.

So, For this purpose, we know that the

The mean is found by adding all of the numbers together and dividing by the number of items in the set.

And

The median is the middle number in a sorted, ascending or descending list of numbers

From the given information:

The data set are:

1,20,1, 49, 16, 5, 3, 6

Then

According mean definition,

Mean = 1+20+1+ 49+ 16+ 5+ 3+6/8

Mean = 101/8

Mean = 12.625

Then

The data set is 1,3,5,6,16,20,49.

Median = 8 terms /2

Median = 4th term

Median = 6.

So, The mean and the median value of the given data set is 12.62 and 6.

Answer:

y = -5/4x + 1

Step-by-step explanation:

DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.

∠TAC = ∠ABC  (The angle between the chord and the tangent is equal to the angle in the alternate segment)

Since, EDCB is a cyclic quadrilateral,

     ∠CBD + ∠CED = 180  ----- I

-      ∠CED + ∠AED = 180   -----II

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

   ∠ CBD =  ∠AED

Also, ∠ CBD = ∠ EAT( A is tangent to the circle)

So, ∠ EAT = ∠ AED ( Alternate interior angle)

So, DE || ST

Therefore, DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.

We get the expression for the statement "The sum of eight and half of a number" as (16 + x) / 2.

We are given a statement:

The sum of eight and half of a number.

We have to form an expression for the same.

An expression means a combination of numbers and variables.

Let the number be a variable say x.

Now we need the half of a number.

1 / 2 of x = x / 2

Now we need the sum of 8 and x / 2.

So, it will be:

8 + x / 2

= (16 + x) / 2

Therefore, we get the expression for the statement "The sum of eight and half of a number" as (16 + x) / 2.

Answer:

∠ N = 10° , arc RS = 134°

Step-by-step explanation:

the measure of an inscribed angle is half the measure of its intercepted arc.

(5)

∠ N is an inscribed angle and we require arc LM

the measure of the arcs in a circle = 360°

note LN is the diameter so arc LN = 180°

Then

LM + MN + LN = 360°

LM + 160° + 180° = 360°

LM + 340° = 360° ( subtract 340° from both sides )

LM = 20°

then

∠ N = [tex]\frac{1}{2}[/tex] LM = [tex]\frac{1}{2}[/tex] × 20° = 10°

(6)

∠ Q is an inscribed angle so its intercepted arc is twice its measure

arc RS = 2 × 67° = 134°

Equation of the book on how many pound the books weigh is T = w*n and the weight of the books is 175/3 pounds.

It is given in the question that the book weighs 4 and 3/8 pounds and the number of copies that are needed to mail are 5.

We have to find the equation to find the weight of 5 copies of the book.

The equation will be:-

Total weight of books = Weight of 1 book * Number of copies of book

Let total weight be T

Let weight of 1 book = w

Let number of copies of a book = n

Hence, equation becomes:-

T = w*n

We can find the total weight of the books.

T = (4 and 3/8 )*5

T = (35/3)*5

T = 175/3 pounds

Osvoldo did not meet his goal of getting at least 30% carbohydrates

Although a part of your question is missing, you might refer to this full question: Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains. Did Osvoldo meet his goal?

Total carbohydrates he ate = 220 grams

Carbohydrates intake from whole grains = 55 grams

Percentage of carbohydrates in whole grains = (Carbohydrates from whole grain/Total carbohydrate intake)*100

=(55/220)*100

=0.25*100

=25%

Osvoldo got 25% carbohydrates as against his goal of at least 30% carbohydrates

Hence, he did not meet his goal of getting at least 30% carbohydrates

If a bottle weighs 300g and can hold 630ml, then it will weigh approximately 930g when filled with water.

As per the question statement, a bottle weighs 300g and can hold 630ml.

We are required to find out the weight of the bottle when it is filled up with water.

To solve this question, we need to know about the concept of density of a substance, i.e.,

[tex]Density=\frac{Mass}{Volume}\\ or, Mass=[Density*Volume][/tex].

And density of water is 1gm/ml, i.e., 1gm of water has a mass of 1ml.

Using the above info, we will calculate the mass of 630ml of water and then we will have to add up the mass of water and the mas of the bottle to obtain our desired answer.

Using the unitary method, if 1ml of water has a mass of 1gm, then,

630 ml of water has a mass of [tex](630*1)=630\\[/tex] gms.

Hence, total weight of the bottle filled with water will be

[tex](630+300)=930[/tex] gms.

I am not sure myself but I think the answer is 2.3 hours per week.

After simplifying the equation we acquire the value of x as:

x = 1.225 or x = ₋12.225

Given the equation is x² ₊ 11x ₊ 15 = 30

arrange the constants on one side.

x² ₊ 11x = 30 ₋ 15

x² ₊ 11x = 15

x² ₊ 11x ₋ 15 = 0

now simplify the equation using the formula: -b±√b²₋4ac / 2a

in the equation we have the values for a = 1 , b = 11 and c = ₋15

substitute the values and get the value of x.

= ₋11 ± √(11)² ₋ 4(1)(₋15) / 2(1)

= ₋11 ± √121 ₊ 60 / 2

= ₋11 ± √181 / 2

= ₋11 ± 13.45 / 2

= ₋11 ₊ 13.45 / 2 or ₋11 ₋ 13.45 / 2

= 2.45/2 or ₋24.45/2

= 1.225 or ₋12.225

Therefore x value is 1.225 or ₋12.225

If the samples are large and the standard deviations are small, the differences between the two samples are least likely to be statistically significant.

The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

"Statistical significance precision" tells us, in Redman's words, "whether a result is probably caused by chance via some factor of interest." A significant finding simply means that you should consider it. can be sure that it is true and not that you were just lucky (or unlucky) in the sample you chose.
