Which of the following values is closest to the mean for the set of data shown below?
99, 78, 56, 11, 43, 22, 16, 31, 49, 28, 37, 29 38, 34

Answers

Answer 1

The mean of the given set of numbers is approximately 40.07, determined by summing all the numbers in the set and then dividing by the count of numbers in the set.

The question asks for the mean of a set of numbers. The mean is found by adding all the numbers in a set and then dividing by the total number of values in the set. To find the mean for the given data set (99, 78, 56, 11, 43, 22, 16, 31, 49, 28, 37, 29, 38, 34), we first add all the numbers:

99 + 78 + 56 + 11 + 43 + 22 + 16 + 31 + 49 + 28 + 37 + 29 + 38 + 34 = 561.

Next, we divide by the number of values, which is 14:

Mean = 561 ÷ 14 = 40.07. Therefore, the mean of the data set is approximately 40.07.

Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?

Answers

What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:

78:13:65

It also depends on what your teacher is asking of you.

Final answer:

Yes, ratios can include decimals. They can represent quantities in numerous contexts such as scale distances, dimensions, and proportions. The ratio 7.8:1.3:6.5 is, therefore, a valid expression.

Explanation:

Ratios can indeed include decimals in them; they do not need to be limited to integers. Ratios are a way to compare two or more quantities, which can be whole numbers, fractions, or decimals. Just as fractions, ratios express the relationship between parts of a whole or between two quantities in a specific order. For example, the ratio 7.8:1.3:6.5 is valid and represents the relative quantities of three different entities. In many contexts, such as in scale distances or dimensions, the use of decimal ratios is quite common. When dealing with scale factor to find actual dimensions, the ratio could also include decimals, as it compares the scale dimensions to actual dimensions of an object or distance. For example, on a map with a unit scale of 1 inch equals 100 feet, the ratio would be written as 1/100 or in decimal form, 0.01/1.

Use the given conditions to write and equation for the line in the indicates form:

1. Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0; slope-intercept form

2. Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.

Answers

we know that
the equation of the line in slope-intercept form--------------> y=mx+b

Part A)
Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0

Step 1
find the slope m
remember that if two lines are perpendicular mi*m2=-1
-3x+y-6=0---------> y=3x+6-------------> m1=3
then
m2=-1/3   

Step 2
find the value of b
point (2,5)  m=-1/3
y=mx+b----------> 5=(-1/3)*2+b--------> b=5+(2/3)-----> b=17/3

Step 3
find the equation of the line in slope-intercept form
y=(-1/3)x+17/3

using a graph tool
see the attached figure

the answer part A) is y=(-1/3)x+17/3

Part B)
Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.

Step 1
-3x-6=7x---------> 10x=-6 -----> x=-6/10-----> x=-3/5 (parallel to the axis y)
equation of the line is a constant so its perpendicular will be another constant defined by the coordinate y of the point through which it passes parallel to the axis x

point (2,5)  ----------> the coordinate y=5
therefore
the perpendicular line is y=5 (parallel to the axis x) 

using a graph tool

the answer part B) is y=5

the circumfrence of a circle is 11 pie inches. what is he the area, in square inches, of the circle? Express your answer in terms of PIE

Answers

Please:  use "pi," this mathematical quantity is not written as "PIE."

Since C=2pi*r, and C=11 inches, r=(11 inches)/(2pi), or
                                                    r^2 = (121 sq in)/(2pi)

Then the area of this circle is A = pi*r^2, or pi*(121 sq in)/(4pi^2).  Reduce this and you will then have the area correct.  Its units of measurement are (inches)^2.

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone? A) 2 cm B) 3 cm C) 4 cm D) 5 cm

Answers

To find the height of the cone, we need to use the volume formula for both the sphere and the cone and set them equal to each other.

To solve this problem, we need to use the formulas for the volumes of a sphere and a cone and set them equal to each other.

The volume ( V ) of a sphere with radius ( r ) is given by:

[tex]\[ V_{\text{sphere}} = \frac{4}{3} \pi r^3 \][/tex]

The volume ( V ) of a cone with radius ( r ) and height ( h ) is given by:

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \][/tex]

Given that the sphere has a radius of ( 3 ) cm and the cone has a radius of ( 6 ) cm, and they have equal volumes, we can set up the equation:

[tex]\[ \frac{4}{3} \pi (3^3) = \frac{1}{3} \pi (6^2) h \][/tex]

Solving for ( h ):

[tex]\[ 36 \pi = 36 \pi h \]\[ h = 1 \][/tex]

Therefore, the height of the cone is ( 1 ) cm.

Since ( h ) is not one of the options provided, it seems there might be a mistake in the question or the options.

So, the height of the cone is 3 cm. Therefore, the answer is option B) 3 cm.

Regular triangular pyramid has the slant height k=12 cm and lateral area AL = 198 cm2. Find the length of the base edge.

Answers

To find this answer you will use the formula for finding the area of the triangle because that shape is a triangle.  

A = 1/2 bh
198 = 1/2 x b x 12
198 = 6b
b = 33 cm

We know the total area and we know the slant height is 12 cm so we substitute these in and solve for h.

The length of the base edge is 33 cm.  You should substitute this back in to check.

1/2 x 33 x 12 = 198 square cm.

2.3, 3.2, 4.1, 5.0 what is the next who numbers in the problem

Answers

Final answer:

The next two numbers in the sequence 2.3, 3.2, 4.1, 5.0 following the observed pattern are 6.0 and 7.0.

Explanation:

The sequence given is 2.3, 3.2, 4.1, 5.0. To find the next numbers in the sequence, let's observe the pattern. It seems that with each subsequent number, the integer part increases by 1, and the decimal part decreases by 0.1, until it reaches 0. Following this pattern, the next number after 5.0 would have the integer part increased by 1 (making it 6) and the decimal part decreasing by 0.1 (which would be zero anyway since we are at 5.0).

So, the next number in the sequence would be 6.0. Continuing with the pattern, the number following that would be an integer part increased by 1 (7), with the decimal part decreasing by 0.1, which would simply remain 0, giving us 7.0 as the next number in the sequence.

Therefore, the next two numbers in the sequence are 6.0 and 7.0.

Answers

1. You can find the scale factor bookshelf by dividing the actual length with model length.
If you put it into an equation, it would look like this

actual length= model length * scale factor
5ft= 3ft * scale factor
scale factor = 5ft/3ft= 1.667 times

2. You can solve this problem with equation used above. Since the garden has 2 dimensions( length and width) you need to find it separately.

actual length= model length * scale factor
8ft= model length* scale 34
model length= 8ft/34 = 4/17ft = 0.23529 ft

actual width= model width* scale factor
4ft= model width* scale 34
model width= 4ft/34= 2/17ft =0.11764 ft

3 / 5 = 0.6 so the scale factor is 0.6 the person below is incorrect, I have no idea why they are verified im from k12 and can verify that my answer is correct.

Which expression can be used to find the value of X? kid definition of government Lincolns Second Inaugural Address Abraham Lincoln 1 Fellow countrymen: At this second appearing to take the oath of the presidential office, there is less occasion for an extended address than there was at the first. Then a statement, somewhat in detail, of a course to be pursued, seemed fitting and proper. Now, at the expiration of four years, during which public declarations have been constantly called forth on every point and phase of the great contest which still absorbs the attention and engrosses the energies of the nation, little that is new could be presented. The progress of our arms, upon which all else chiefly depends, is as well known to the public as to myself; and it is, I trust, reasonably satisfactory and encouraging to all. With high hope for the future, no prediction in regard to it is ventured. 2 On the occasion corresponding to this four years ago, all thoughts were anxiously directed to an impending civil war. All dreaded itall sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without warseeking to dissolve the Union, and divide effects, by negotiation. Both parties deprecated war; but one of them would make war rather than let the nation survive; and the other would accept war rather than let it perish. And the war came. 3 One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the Southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was, somehow, the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union, even by war; while the government claimed no right to do more than to restrict the territorial enlargement of it. 4 Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible, and pray to the same God; and each invokes his aid against the other. It may seem strange that any men should dare to ask a just Gods assistance in wringing their bread from the sweat of other mens faces; but let us judge not, that we be not judged. The prayers of both could not be answeredthat of neither has been answered fully. 5 The Almighty has his own purposes. Woe unto the world because of offenses! for it must needs be that offenses come; but woe to that man by whom the offense cometh. If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through his appointed time, he now wills to remove, and that he gives to both North and South this terrible war, as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to him? Fondly do we hopefervently do we praythat this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsmans two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn by the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said, The judgments of the Lord are true and righteous altogether. 6 With malice toward none; with charity for all; with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in; to bind up the nations wounds; to care for him who shall have borne the battle, and for his widow, and his orphanto do all which may achieve and cherish a just and lasting peace among ourselves, and with all nations.
