FALSE. The number of degrees of freedom in cross-tabulation data is calculated by subtracting 1 from the product of the number of rows and columns.

Therefore, in this case, the number of degrees of freedom would be (3-1) x (4-1) = 6.

Degrees of freedom refer to the number of independent pieces of information in a data set, which can be used to calculate statistical significance and test hypotheses.

In cross-tabulation, degrees of freedom indicate the number of cells in the contingency table that are not predetermined by the row and column totals.

Answer: 192 cubic inches

Step-by-step explanation:

Answer:

x = 3

y = 0

Step-by-step explanation:

2x - 4y = 6

-2x - 3y= -6, multiply both sides of the equation by -1:

2x + 3y = 6, then 2x = 6 - 3y

substitute for 2x in first equation:

(6 - 3y) -4y = 6

6 - 3y - 4y = 6

combine like terms:

-7y = 0

y = 0

2x - 0 = 6

divide both sides by 2:

x = 3

Answer:

See below

Step-by-step explanation:

For seg FG to be tangent to the circle with center E, the side lengths 6, 10, 12 must follow the rule of Pythagorean triplets.

So,

\( {10}^{2} + {6}^{2} = 100 + 36 = 136 \\ \\ {12}^{2} = 144 \\ \\ \because \: {10}^{2} + {6}^{2} \neq \: {12}^{2} \\ \)

From above it is obvious that given segment lengths doesn't follow the Pythagorean triplet rule. Therefore, seg FG is not tangent to the circle with center E.

1. Surveys are used to obtain specific information from a group of people. It is administered by politicians, professionals, sociologists, and other groups to obtain data from their subjects of interest.

2. Experiments are used to establish cause-and-effect relationships. Scientists use them for highly-controlled tests to give/withdraw credence to some hypotheses.

Step-by-step explanation:

Surveys, when applied to human subjects, are used to obtain data from a selected sample of subjects. Surveys, which can be applied through mails, telephones, the internet, in-person, and through other means are aimed at getting the opinions, thoughts, and beliefs of the participants. It is administered by politicians, professionals, sociologists, and other groups to obtain data from their subjects of interest. This data can be qualitative or quantitative.

Experiments are administered to provide support or refute a given hypothesis. They establish cause and effect relationships. Scientists use them for highly-controlled tests to give/deny credence to some hypotheses. Positive controls establish the hypothesis as true. They could be conducted in the laboratory, in the field, or through observations.

Answer:

1. The x-axis represents the time duration Arthur spends on the different activities

2. The y-axis represents Arthur's distance from a reference location (home)

3.  During parts 2 and 4 Arthur's distance from home decreases

4. Arthur is waiting for bagels in part 3

5. i) The part of the graph that would change if Arthur's pace had not been constant after leaving the bagel shop is part 4

ii) Where by the Arthur's pace is not constant in part 4, there would be more than one different slopes along part 4 and part 4 will not be straight

6) i) If Arthur had spent less time reading his newspaper, the part that would change is part 1

ii) The horizontal length of each part is related directly to the duration of time spent in that part

For a reduction of time in part 1, the length of part 1 will be reduced proportionately to allow for the reduction of time spent in the part

Step-by-step explanation:

Answer:

1. What does the x-axis represent in this situation?

The x-axis represents time.

2. What does the y-axis represent?

The y-axis represents distance.

3. During which parts of the graph does Arthur's distance from home decrease?

Sections 2 and 4.

4. When is Arthur waiting for bagels? Explain how you know.

Section 3. The flat areas represent times when Arthur is not moving. We know that the first flat area shows Arthur reading his newspaper, and the third is when he reaches home; so the second flat area represents the time in which Arthur is waiting for bagels.

5. If Arthur's pace had not been constant after leaving the bagel shop, which part of the graph

would change? Explain how that part of the graph would change.

The part of the graph that would change is part 4. If his pace was not constant, section 4 would not be uniform, and would have many abnormalities. Essentially, Arthur would be randomly speeding up and slowing down.

6. If Arthur had spent less time reading his newspaper, which part of the graph would change? How would that part change?

If Arthur had spent less time reading his newspaper, the whole graph would change. Section one would be shorter, and the entire line would also be shorter. The distance on the graph from the beginning of section 1 to the end of section 5 would be reduced.

Answer:

QSR equal 82

QPR equal 41.

Step-by-step explanation:

Arc QR equal 82. Arc QSR is part of Arc QR, so that means the arc measure equal the angle measure in between the arc. So that means ARC QSR equal 82.

Angle QRS is a inscribed angle of angle QPR so that means

Angle QPR is half of Angle QSR.

\( \frac{82}{2} = 41\)

Angle QPR equal 41.

The solution is: the value of the angles are,

QSR equal 82

QPR equal 41.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

Here, we have,

Arc QR equal 82. Arc QSR is part of Arc QR,

so that means the arc measure equal the angle measure in between the arc.

So that means ARC QSR equal 82.

Angle QRS is a inscribed angle of angle QPR so that means

Angle QPR is half of Angle QSR.

82/2

=41

Angle QPR equal 41.

Hence, The solution is: the value of the angles are,

Any smooth curve connecting two points is called an arc. The correct option is c.

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

\(\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}\)

where

θ is the angle, that arc creates at the centre of the circle in degree.

If the central angle has a measure of π/2(90°), then the length of the arc will be one-fourth of the total, while if the measure of the angle is π(180°), then the length of the arc will be half of the total.

Similarly, if the measure of the angle is 3π/4, then the length of the arc will be three-fourth of the total, while if the measure of the angle is 2π(360°), then the length of the arc will be 2πr.

Hence, the correct option is c.

Step-by-step explanation:

Answer:

The parts of the number are 200 and 320

Step-by-step explanation:

System of Equations

Suppose a and b are the two parts. They must meet two conditions:

\(a+b=520\qquad\qquad [1]\)

\(\displaystyle \frac{a}{b}=\frac{5}{8}\qquad\qquad [2]\)

From [1], we have:

\(b=520-a\)

Replacing in [2]:

\(\displaystyle \frac{a}{520-a}=\frac{5}{8}\)

Cross-multiplying:

\(8a=5*(520-a)\)

Operating:

\(8a=2600-5a\)

Joining like terms:

\(13a=2600\)

Solving:

\(a=2600/13=200\)

a=200

Since:

\(b=520-a\Rightarrow b=520-200\)

b=320

The parts of the number are 200 and 320

The simplification of the expression 6 + (5 + x) is 11 + x

6 + (5 + x)

Based on the associative property

= (6 + 5) + x

Add 6 and 5

= 11 + x

Associative property states that the rearranging of parenthesis in an expression will not change the result.

Commutative property on the other hand states that the numbers on which we operate can be interchanged or moved from their position without making any difference to the result.

The problem asks to find the value of (F•G) (-9) where F(x) = x^2 - 13 and G(x) = 6 - x.

To solve this, we first find the product of function F(x) and G(x) by substituting G(x) in place of x in F(x), which gives us (F•G) (x) = (x^2 - 13) (6 - x).

Then we evaluate this expression at x = -9 to get (F•G) (-9) = (-9^2 - 13) (6 - (-9)) = 0.

We have:

(FG)(x) = F(x) · G(x)

So, (FG) (-9) = F (-9) · G (-9):

F (-9) = (-9) ^2 - 13 = 64

G (-9) = 6 - (-9) = 15

Therefore, (FG) (-9) = F (-9) · G (-9) = 64 · 15 = 960.

If an employee has already measured out 59 pounds of wild rice. The  number of pounds of long grain brown rice should she add to make the blend is: 88.5 pounds of long grain.

Let x represent number of pounds of long grain

6.45×59+3.95x=(59+x)×4.95

380.55+3.95x =292.05+4.95x

380.55–x =292.05

-x=292.05-380.55

-x = -88.5

x = 88.5 pounds of long grain

OR

6.45×59+3.95x=(59+x)×4.95

x=(6.45-4.95)×59

x=1.5×59
