hours?

Answer:

There are 6

Step-by-step explanation:

There are two within each circle.

Answer: 18.84 radians

Step-by-step explanation:

Because the first equation is already solved for y we can substitute 3x−5 for y in the second equation and solve for x:

y=x−3 becomes:

3x−5=x−3

3x−5+5−x=x−3+5−x

3x−x−5+5=x−x−3+5

3x−1x−0=0+2

2x=2

2x/2=2/2

2x/2=1

x=1

Substitute

1 for x in the first equation and calculate y:

y=3x−5 becomes:

y=(3×1)−5

y=3−5

y=−2

The solution is x=1 and y=−2 or (1, -2)

Yes, one meter of ribbon will be enough to make the bow because one meter is equal to  1.094 yards.

One meter is equal to  1.094 yards. So, one meter is longer than one yard.

Since Amelia needs one yard of ribbon to make the bow, and she can only find ribbon sold by the meter, which is longer than a yard, one meter of ribbon will be enough to make the bow.

Thus, She can purchase one meter of ribbon to make the bow.

There are various properties of subtraction , out of which four of them are ,

Subtraction means to reduce one number or quantity from another.  It is one of the most common mathematical operations which are present as well as it is represented by the symbol , " - " .

The associative property does not apply to subtraction which are performed between  whole-number. The order of subtraction is significant.

The distributive property helps to simplify the difficult algebraic expression. As a result, the distributive property favors multiplication over subtraction. The property states that subtracting any number from the same number results in the number 0.

Increasing or decreasing the size of a figure (referred to as the preimage) to produce a new figure is a type of transformation termed dilation. How much the dilation image will enlarge or reduce in size relative to the preimage is determined by the scale factor, r. Every time, k will have a value larger than 0.

A transformation in geometry is an action that shifts, rotates, or modifies an existing shape to produce a brand-new shape.

Increasing or decreasing the size of a figure (referred to as the preimage) to produce a new figure is a type of transformation termed dilation.

How much the dilation image will enlarge or reduce in size relative to the preimage is determined by the scale factor, r.

A two-scale factor dilation has been applied to Image A in relation to its origin. It is important to note that every coordinate point in the dilation picture is twofold that of the preimage.

The notation shown below can be used to represent a dilation with a scale factor close to the origin:

In statistical or machine learning models, the differences between actual and expected data values are referred to as residuals.

They act as a diagnostic instrument for assessing the caliber of a model. They are also known as errors.

The primary column, Inflation, of the table below provides details on US inflation for each month of 2017. Forecasts from a model that seeks to predict the rate of inflation are shown in the Predicted column.

Following are the calculations for the residuals: Residual is equal to predicted inflation.

The Residual column contains them.

We can identify the base and its exponent as the exponent indicates the number of times the base is used as a factor in an exponential notation.

An exponent is the number of times a number has been multiplied by itself. For instance, the phrase 2 to the third, which is represented as 23, means 2 x 2 x 2 = 8, not 23, and 2 x 3 = 6, respectively. Remember that every number multiplied by one is equal to itself.

Exponents are a technique of expressing extremely large numbers in terms of powers. The number of times a number has been multiplied by itself is the exponent, so to speak. For instance, the result of multiplying the number 6 by itself four times is 6 6 6 6. This can be expressed as 6⁴. Here, the exponent and base are 4 and 6, respectively.

An exponential number takes the shape of a, where an is multiplied by itself n times. The simple example is 8=23=222. In exponential notation, A is referred to as the base, whereas n is referred to as the power, exponent, or index. In scientific notation, 10, which is a specific illustration of exponential numbers, is typically always used as the base number.

Exponential notation make it easy to express powers succinctly. The exponent displays the base's multiplicative power. It can be written as 2 2 2 2=25 for the integer 32 because 2 is the "base" and 5 is the "exponent." The correct translation of this phrase is "two to the fifth power."

The solution to the implicit differentiation problem is dy/dx = -16x/2y.

To solve this problem, we must use implicit differentiation. This means that we must differentiate both sides of the equation with respect to the independent variable, x. We can do this by taking the derivative of both sides of the equation.

The derivative of 8x^2 is 16x and the derivative of y^2 is 2y dy/dx.

Therefore, the equation becomes: 16x + 2y dy/dx = 0

We can then solve for dy/dx by dividing both sides by 2y, which gives us dy/dx = -16x/2y.

Therefore, the solution to the implicit differentiation problem is dy/dx = -16x/2y.

The probability of being a senior citizen and white is: (0.63)(0.3) = 0.189.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty.

Given that the probability of identifying white is 0.63.

Then the probability of not white is:

1 - 0.63 = 0.37

Given that the probability of being a senior citizen is 0.3.

Then the probability of not a senior citizen is:

Compare to last year the population of the Boom town increased by 25%  which is equal to 6000 then population of the last year is 4800.

As given in the question,

Present year population of the Boom town is equal to 6000

Let us consider 'y' be the population of Boom town last year.

Percentage of increase in population = 25%

Equation formed for the given condition is :

y + 25%y = 6000

⇒ y + (25/100)y = 6000

⇒ (100 + 25 / 100 )y = 6000

⇒ y  =  ( 600,000 / 125 )

⇒ y  = 4,800 population of Boom town last.

The measures of the angle are a = 84°,  b = 84°, c = 96°, d = 58°, e = 38° and f = 142°

Angle geometry is a branch of mathematics that deals with the properties and relationships of angles in geometric figures.

Check the attached image for labeling

d = 180 - 122 = 58°    (sum of angles on a straight line)

c = 96°   (vertically opposite angles are equal)

a = 180 - 96 = 84°    (sum of angles on a straight line)

b = a  (vertically opposite angles are equal)

b = 84°

e = 180 - b -d  (sum of angles in a triangle)

e = 180 - 84 - 58 = 38°

f = 180 - e     (sum of angles on a straight line)

f = 180 - 38 = 142°

What is linear equation ?

Linear equation can be defined as equation in which highest degree is one.

In order to determine the equation for this relationship, we need to first find the slope between these two values. There are two ways to do this:

1. Create a graph

*Create a graph with the x-axis representing the years past 2000 (so 2000 would be 0 and 2003 would be 3 and so on)

*Use the fact that slope=rise/run to get slope=2.7/3 (because we rise 87-84.3=2.7 and run 3 (from 2000 to 2003), and 2.7/3=27/30=9/10

*Plug this and the point (0, 84.3) into the formula y=mx+b to find the y-intercept of your equation

--> 84.3=(9/10)(0)+b --> b=84.3

So, your equation can be written now as y=(9/10)x+84.3

[Note: To check, if you plug in 3 you should get 87, and you do, so it works!]

2. Use the slope formula

Alternatively, you could have did slope=(y2-y1)/(x2-x1)=(87-84.3)/(3-0)=2.7/3=9/10

The process here would be the same as above

b) Here, just plug 10 into the equation above (since 10 is the number of years 2010 is after 2000, or 2010-2000=10). Doing this we get:

y=(9/10)(10)+84.3=9+84.3=93.3

A collection of two or more inequalities in one or more variables is known as a system of inequalities.

Two or more inequalities in one or more variables make up a system of inequalities. When a problem calls for a variety of answers and those answers are constrained by multiple factors, systems of inequalities are used.

The intersection region of every solution in the system of inequalities is the system's solution.

Comparable to solving a system of linear equations, solving a system of linear inequalities involves locating the point (or points) of intersection, however this is not the case with inequalities. Instead, the area that fulfils each linear inequality will make up the solution set.

An inequality system's graph shows how the inequalities are resolved.

The system of inequality needs to be fixed by [tex]$y > \frac{2}{3}$ \\ and $x \leq \frac{16}{3}$[/tex]
