Answer:

The middle cells are the joint frequency numbers. When analyzing data in a two-way frequency table, you will be looking for joint relative frequency, which is the ratio of the frequency in a particular category and the total number of data values. The purple cells on this table are all joint frequency numbers.

The numbers in the column on the very right and on the row on the very bottom are the marginal frequency numbers. When analyzing data in a two-way frequency table, you will be looking for marginal relative frequency, which is the ratio of the sum of the joint relative frequency in a row or column and the total number of data values.

Conditional relative frequency numbers are the ratio of a joint relative frequency and related marginal relative frequency.

Step-by-step explanation:

Any obtuse triangle will also have two acute angles.

__

The sum of angles in a triangle is 180°. If one of the angles is 90° or more (a right or obtuse angle), the other two (non-zero) angles must be less than 90°.

An obtuse triangle is one that has an obtuse angle, so both of the remaining angles must be less than 90°, that is, they must be acute angles.

Answer:

Yes

Step-by-step explanation:

Example:

A triangle with angles: 100°, 50°, 30°

Answer:

x = 34t

408

Step-by-step explanation:

x = 34t

x: no. of copies

t: minutes

x = 34(12)

x = 408

Answer:

x

34

= 12

x = total number of copies

total number of copies

copies per minute

= number of minutes copier runs

B )  x / 34 = 12  is correct

Lets split this into two parts; a semi circle and triangle. We can solve fro the area of both individually first.

Area of the Semi Circle:

Formula: A = (πr²)/2

The radius is the diameter divided by two (16 / 2 = 8)

A = (π*8²)/2

A = (π64)/2

A = 200.96/2

A = 100.48 meters

The area of the semi circle is 100.48 meters

Area of the Triangle:

Formula: A = bh/2

A = 16*12/2

A = 192/2

A = 96 meters

The area of the triangle is 96 meters.

To find the total area of the shape, we can add.

100.48 + 96 = 196.48 meters.

Best of Luck!

y = 30.85

10.85

Step-by-step explanation:

One complete cycle is between:

x = 4 and x = 44

Period: 44-4 = 40 cm

Range: 41.7 - 20 = 21.7

Amplitude: 21.7/2 = 10.85

Mean line:

y = 20 + 10.85

y = 30.85

The period of the cosine function is 20, its midline equation is y = 32, and its amplitude is [tex]$\boxed{12}$[/tex].

To analyze the given data, we can notice the sinusoidal nature of the relationship between the number of seconds an object has been moving (x) and its velocity (v(x)$. This indicates that a cosine function can model the data.

Now, let's find the period, midline, and amplitude of the cosine function that models this data.

The period of a cosine function is the distance it takes for the function to complete one full cycle. Looking at the data, we can see that the interval between consecutive peaks or troughs (e.g., between 4 and 24, or 24 and 44) is 20 seconds.

Hence, the period of the cosine function is 20.

The midline of a cosine function is the horizontal line that divides the maximum and minimum values of the function. In this case, since the data oscillates around a central value, it suggests that the midline is not at y = 0.

Instead, it's the average of the maximum and minimum values of the data. The maximum value is 44 and the minimum value is 20, so the midline would be the average of these, which is (44 + 20)/2 = 32.

The amplitude of a cosine function is half the difference between the maximum and minimum values.

In this case, the maximum value is 44 and the minimum value is 20, so the amplitude is (44 - 20)/2 = 12.

So, completing the statements:

- The period of the cosine function is 20.

- The equation of the midline of the cosine function is y = 32.

- The amplitude of the cosine function is [tex]$\boxed{12}$[/tex].

Answer:

y – 1= Three-halves(x + 3)

Step-by-step explanation:

line goes through  (-2, -4) and (2, 2)

goes through (-3, 1)

slope =  (-4 - 2) / (-2 -2)  = -6/-4 = 3/2

1 =  (3/2)*-3 + b

1 = -9/2 + b

b = 1 + 9/2 = 11/2 = 5.5

y = (3/2)*x + 11/2

(y - 1) = (3/2)(x + 3)

The line goes through  (-2, -4) and (2, 2)

goes through (-3, 1)

If slope = (-4 - 2) / (-2 -2)  = -6/-4 = 3/

1 =  (3/2)*-3 + b

1 = -9/2 + b

b = 1 + 9/2 = 11/2 = 5.5

y = (3/2)*x + 11/2

(y - 1) = (3/2)(x + 3)

So the correct answer is option d. y – 1= Three-halves(x + 3).

A coordinate plane is a graphing and description system for points and lines. A vertical (y) axis and a horizontal (x) axis make up the coordinate plane. There are four quadrants in the coordinate plane. The point where these lines connect is called the origin (0, 0).

1)  5.006/1

2)  50.06/10

3)  500.6/100

4)  5006/1000

5)  Simplify:    2503/500

Answer:

x+20

Step-by-step explanation:

As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.

So we plug everything in and we have  4x+5x=180 degrees

4x+5x=9x, so 9x=180

We divide by 9 on both sides to get the value of x, which is 20

Hope it helps!

Answer:

D

Step-by-step explanation:

The length of the paintbrush in centimeters is D. 10.1 cm.

Unit conversion is defined as expressing the same quantity by different measurement units.

For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.

Given that,

Length of the paintbrush in millimeters = 101 millimeters

We have to find the length of the same paintbrush in centimeters.

We have the unit conversion,

1 centimeter = 10 millimeters

So,

1 millimeter = 1/10 = 0.1 centimeters

So, we have to multiply the measurement in millimeter with 0.1.

101 millimeters = 101 × 0.1 = 10.1 centimeters

Hence the length is 10.1 centimeters

[tex]\boxed{m\angle U=40^{\circ}}[/tex]

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any diagram, so I'll assume ΔSTU and ΔDEF are similar. Two triangles are similar if and only if their corresponding angles are congruent and their corresponding sides are in proportion.

So:

[tex]\angle S=\angle D \ldots eq1 \\ \\ \angle T=\angle E \ldots eq2 \\ \\ \angle U=\angle F \ldots eq3[/tex]

We also know:

[tex]\angle S+\angle T+\angle U=180^{\circ} \ldots eq4 \\ \\ \angle D+\angle E+\angle F=180^{\circ} \ldots eq5[/tex]

Suppose we know:

[tex]\angle S=30^{\circ} \\ \\ \angle E=110^{\circ}[/tex]

Then, by eq2:

[tex]\angle T=\angle E =110^{\circ}[/tex]

By substituting ∠S and ∠T into eq4:

[tex]\angle S+\angle T+\angle U=180^{\circ} \\ \\ 30^{\circ}+110^{\circ}+\angle U=180^{\circ} \\ \\ \\ Isolating \ \angle U: \\ \\ \angle U=180^{\circ}-(30^{\circ}+110^{\circ}) \\ \\ \angle U=180^{\circ}-140^{\circ} \\ \\ \angle U=40^{\circ}[/tex]

Finally:

[tex]\boxed{m\angle U=40^{\circ}}[/tex]
