A circle is a curve sketched out by a point moving in a plane. The measure of the ∠ACB or θ is 50°.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

In order to solve the problem, we need to draw a line segment AB. Since A is the center of the circle AC and AC both will be the radius of the triangle ΔABC. Since two sides of the triangle are equal, the measure of ∠ABC and ∠ACB will be equal therefore, we can write,

∠ACB + ∠ABC + ∠BAC = 180°

2∠ACB + 80° = 180°

∠ACB = 50°

Hence, the measure of the ∠ACB or θ is 50°.

1. Initial prediction for the data set with smaller Mean Absolute Deviation was Period A. Prediction was wrong.

2. The Mean Absolute Deviation for Period A is 1.8 and Period B, 1.1

This means that period B has a smaller Mean absolute deviation.

We start by finding the mean for each set;

Period A: Mean = (1×92 + 1×94 + 3×95 + 1×96 + 2×97 + 1×99 + 1×100)/10

= 960/10

= 96

Period B: Mean = (1×94 + 3×95 + 1×96 + 4×97 + 1×98)/10

= 961/10

= 96.1

Period A:

Mean Absolute Deviation = ((92-96) + (94-96) + 3(95-96) + (96-96) + 2(97-96) + (99-96) + (100-96))/10

Mean Absolute Deviation = (4 + 2 + 3 + 0 + 2 + 3 + 4)/10

Mean Absolute Deviation = 1.8

Period B:

Mean Absolute Deviation = ((94-96.1) + 3(95-96.1) + (96-96.1) + 4(97-96.1) + (98-96.1))/10

Mean Absolute Deviation = (2.1 + 3.3 + 0.1 + 3.6 + 1.9)/10

Mean Absolute Deviation = 1.1

The logarithm expression can be simplified to:

In(6x^9)-In(x^2) =7·ln(6x)

There are some logarithm properties we can use here.

log(a) - log(b) = log(a/b)

log(a^n) = n*log(a)

(these obviously also apply to the natural logarithm)

Now let's look at our expression, it says that:

In(6x^9)-In(x^2)

Using the first rule, we can rewrite this as.

In(6x^9)-In(x^2) = ln(6x^9/x^2)

Now solving the quotient in the argument:

ln(6x^9/x^2) = ln(6x^7) = 7·ln(6x)

Dependent samples are paired measurements for one set of items while independent samples are measurements made on two different sets of items

If the values in one sample reveal no information about those of the other sample, then the samples are independent. However, if the values in one sample reveal information about those of the other sample, then the samples are dependent.

From the above descriptions, we see that the effectiveness of a headache medicine is measured by the intensity of headaches in patients before and after drug treatment.

Thus, It is a dependent sample because it is a paired measurement of the intensity of headache before and after drug treatment for a set of item (which is the effectiveness of the headache medicine). Also, it is a dependent sample because the value in one sample (before drug treatment) reveals information about the other sample (after drug treatment).

Therefore, it is a dependent sample.

The value of variable x is 19.20.

Let's find the value of variable x in the equation.

A variable is a number represented with letters in an equation.

Therefore,

x / 6 + 4 / 10 = 3 + 6 / 10

Therefore, let's find the variable x.

10x + 24 / 60 =  30 + 6 / 10

10x + 24 / 60 = 36 / 10

60 × 36 = 10(10x + 24)

2160 = 100x + 240

2160 - 240 = 100x

1920 = 100x

divide both sides by 100

x = 1920 / 100

Using the surface area formula of the Right rectangular prism, we know that the surface area is (B) 45 ft² respectively.

The three-dimensional solid shape of a right rectangular prism has six faces, twelve edges, and eight vertices.

It also goes by the name cuboid.

A right rectangular prism has six rectangle-shaped faces.

Books, aquariums, and bricks are some examples of right-rectangular prisms.

The formula for a rectangular prism's surface area is thus stated as Surface Area of a Rectangular Prism = 2 (lh + wh + lw) Square Units.

So, the surface area formula is as follows:

A=2(wl+hl+hw)

Now, insert values as follows:

A=2(wl+hl+hw)

A=2(5+1.33+2.5)

A=44.95

9x+7y=18

Step 1: Add -9x to both sides.

9x+7y+−9x=18+−9x

7y=−9x+18

Step 2: Divide both sides by 7.

7y/7=−9x+18/7

y=−9/7x+18/7

Given :

To Find :

Solution :

\(\qquad { \dashrightarrow \: { \sf{2x + 7y + 7x = 18}}}\)

Adding the like terms :

\(\qquad { \dashrightarrow \: { \sf{ 7y + 9x = 18}}}\)

Transposing 9y to the other side which then becomes negative :

\(\qquad { \dashrightarrow \: { \sf{ 7y = 18 - 9x}}}\)

Dividing both sides by 7 :

\(\qquad { \dashrightarrow \: { \sf{ \dfrac{7y}{7} = \dfrac{18 - 9x}{7} }}}\)

\(\qquad { \dashrightarrow \: { \sf{ y = \dfrac{18 - 9x}{7} }}}\)

The equation of the line that passes through the point (1,-1) and has a slope of -3 is y = -3x + 4.

An equation is a mathematical statement that express the equality of 2 expression using the equal sign. Equation are used to define relationship between depreciation variable and get be used to solve for the unknown's value when the solved an equation are also used to describe the behaviour of the physical system of the represent law of nature.

The equation in slope-intercept form for the line that passes through the point (1,-1) and has a slope of -3 is y = -3x + 4.

To find this equation, we need to use the point-slope form of a line: y - y1 = m(x - x1). In this equation, (x1, y1) is the point given (1,-1) and m is the slope given (-3).

Substituting in the point (1,-1) and the slope (-3) into the point-slope form gives us: y - (-1) = -3(x - 1).

Solving for y, we get: y = -3x + 4.

Therefore, the equation of the line that passes through the point (1,-1) and has a slope of -3 is y = -3x + 4.

Step-by-step explanation:

The x-coordinates where the graphs of the equations intersect are x = -1 and x = 3

From the question, we have the following parameters that can be used in our computation:

y = 2x

y = x² - 3

The x-coordinates where the graphs of the equations intersect is when both equations are equal

So, we have

x² - 3 = 2x

Rewrite the equation as

x² - 2x - 3 = 0

When the equation is factored, we have

(x + 1)(x - 3) = 0

So, we have

x = -1 and x = 3

The length of the rectangle is twice its width. If its perimeter is 7 1/3 cm, its length will be 22/9 cm, and the width is 11/9 cm.

Let's assume the width of the rectangle is "b" cm.

According to the given information, the length of the rectangle is twice its width, so the length would be "2b" cm.

The formula for the perimeter of a rectangle is given by:

Perimeter = 2 * (length + width)

Substituting the given perimeter value, we have:

7 1/3 cm = 2 * (2b + b)

To simplify the calculation, let's convert 7 1/3 to an improper fraction:

7 1/3 = (3*7 + 1)/3 = 22/3

Rewriting the equation:

22/3 = 2 * (3b)

Simplifying further:

22/3 = 6b

To solve for "b," we can divide both sides by 6:

b = (22/3) / 6 = 22/18 = 11/9 cm

Therefore, the width of the rectangle is 11/9 cm.

To find the length, we can substitute the width back into the equation:

Length = 2b = 2 * (11/9) = 22/9 cm

So, the length of the rectangle is 22/9 cm, and the width is 11/9 cm.

The rate of decrease of the weather in degrees per hour is 2 degrees.

The time elapsed is from 5:00 PM to 9:00 PM, which is 4 hours.

The temperature dropped from 20 degrees to 12 degrees, which is a change of -8 degrees.

Therefore, the rate of decrease of the weather in degrees per hour is:

-8 degrees / 4 hours = -2 degrees per hour

A measurement of how quickly the temperature changes over time is the rate of change. Depending on the time frame being considered, it is typically represented in units of degrees per hour, degrees per minute, or degrees per second. Depending on whether the temperature is rising or falling, the rate of temperature change can be either positive or negative. The temperature rises when the rate of change is positive; it falls when the rate of change is negative.

Many variables, including the amount of sunlight, wind speed, humidity, and the time of day, have an impact on the pace of temperature change. Generally speaking, temperature varies more quickly during the day than it does at night, and it varies more quickly in places with less foliage and more exposed ground. Human activity, such as the emission of greenhouse gases into the atmosphere, which can eventually lead to an increase in global temperatures, can also have an impact on the pace of change of temperature.
