You have the following equation:

x - 3 = x²

In order to determine if the given equation is linear in x, you consider that a linerar equation is an equation in which the maximum exponet of the variable is 1. In this case you have that the higher exponent of the variable, which is x, is 2. 2 is the higher exponent, Becuase of that, the given equation is not linear, instead of that, the equation is quadratic.

The number of groups of 1/9 in 2 are 18.

The value of 2 ÷ (4/9) = 9/2.

We can see a number line with equal intervals of 1/9.

We have to find the number of groups of 1/9 in 2 and the value of 2 ÷ (4/9) .

As we can see in the number line,

2 is two intervals after 16/9 , hence,

2 = 16/9 + 1/9 + 1/9 = 16/9 + 2/9 = 18/9

We can write it as,

(1/9)*18

Hence, there are 18 groups of 1/9 in 2.

The value of  2 ÷ (4/9) = 2*(9/4) = 18/4 = 9/2.

The correct interpretation of the 95% confidence interval is that:

We are 95% sure that the true population mean widget width is between 11.5 and 27.3 units.

The x% confidence interval means that it is x% likely that the population parameter(mean/proportion/standard deviation) is between the bounds of the confidence interval, given by a and b.

The bounds of the confidence interval are given by the estimate of the population parameter plus/minus the margin of error found from the sample size/standard deviation.

In the context of this problem, the bounds of the interval are already given as follows:

11.5 < μ < 27.3

The parameter being estimated is the mean widget width, hence the interpretation is that we are are 95% sure that the true population mean widget width is between 11.5 and 27.3 units.

Given:

KP = PL

GH = 36 ft

Let's find the measure of arc GM.

Apply the angle arc relationship to find the measure of angle KGL:

GKP + GLP + KGL + KGP = 360 degrees

90 + 90 + 26 + KPL = 360

206 + KPL = 360

Subtract 206 from both sides:

206 - 206 + KPL = 360 - 206

KPL = 154 degrees

To find the measure of arc GM, we have:

Therefore, the length of arc GM is 77 degrees

The value of the base number, r is 75 and the corresponding algebraic expression is 0.2r = 15.

What is an algebraic expression and how is it formed?
Variables and constants are used to create algebraic expressions using a variety of techniques. It is a mathematical expression made up of terms and includes variables, constants, and algebraic operations like addition, subtraction, etc. When operations like addition, subtraction, multiplication, division, etc. are performed on any variable, the resulting equations are called algebraic expressions. An algebraic expression (or variable expression) is a grouping of terms that have undergone operations like addition, subtraction, multiplication, division, etc.

Given, the base number is = r
One fifth of the base number will be = (1/5)r = 0.2r
Also, one fifth of r is 15, thus 0.2r = 15 ⇒ r = 15/0.2 = 75
Thus, the value of the base number, r is 75 and the corresponding algebraic expression is 0.2r = 15.

The algebraic expression "One fifth of r is 15" is represented as r/5 = 15. Solving for r, r = 75.

Let's break this down step-by-step:

1. "One fifth of r" means you are dividing r by 5, which in algebraic terms would be represented as r/5.

2. The phrase "is" in algebra typically signifies the equals sign (=).

3. Finally, "15" is just the number 15.

Putting these together, the algebraic expression for "One fifth of r is 15" is r/5 = 15.

To clarify this further, this equation is saying that if you take the value of r, divide it by 5, the result should be 15. This is an equation you can solve to find the value of r.

If you're curious, solving this equation for r would look like this:

Step 1: Start with the equation r/5 = 15.
Step 2: To isolate r, you need to get rid of the division by 5. You can do this by multiplying both sides of the equation by 5.
Step 3: This gives you r = 15 * 5.
Step 4: Calculate 15 * 5 to get 75. So r = 75.

So, if one fifth of r is 15, then r would be 75.

In this question, we have been given the number of people employed in some country as medical assistant.

We need to write an equation that models the number of people employed in some country as medical assistant in the last year x.

the number of people employed in some country as medical assistant:

in 2004 = 359 thousand

and by 2014 this number is expected to be  560 thousand.

We find the rate of employment.

Consider (x1, y1) = (0, 359) and (x2, y2) = (14, 560)

m = (560 - 359)/(14 - 0)

m = 201/14

m = 14.35

We have been given the line must pass through points (0, 359) and (14, 560)

And, we get the y-intercept c = 359

with slope m = 14.35 and y-intercept c = 359, the equation of the line would be,

y = 14.35x + 359

y = 24x + 80

Where x is the number of weeks of saving and y is the dollar amount in her savings

Explanation:

We need to find the equation of the line. If x is the number of weeks of saving and y is the amount in her savings, the equation has the following form

y = mx + b

Where m is the slope and b is the y-intercept.

The slope can be calculated using two points in the line (x1, y1) and (x2, y2) as follows

Then, replacing (x1, y1) = (0, 80) and (x2, y2) = (5, 200), we get:

Additionally, the y-intercept is the point where the graph crosses the y-axis. In this case, the point is (0, 80), so the value of b is 80.

Therefore, the equation of the line is

y = 24x + 80

Where x is the number of weeks of saving and y is the dollar amount in her savings
