The answers are:

[tex]AbsoluteError=20mhz[/tex]

[tex]RelativeError=2.5(Percent)[/tex]

To solve the problem we need to remember that the absolute error is the difference between the expected value and the measured value, also, to calculate the relative error we first need to calculate the absolute error, and then, divide it by the expected measure.

So, calculating we have:

[tex]AbsoluteError=Expected-MeasuredValue\\\\AbsoluteError=800mhz-820mhz=-20mhz[/tex]

We can see that we obtained a negative value, however, when we are working with "absolute" values, the negative symbol is discarded, so, we have that:

[tex]AbsoluteError=20mhz[/tex]

Now, to calculate the relative error, we need to use the following formula:

[tex]RelativeError=\frac{AbsoluteError}{ExpectedValue}*100\\\\RelativeError=\frac{20}{800}*100=0.025*100=2.5(Percent)[/tex]

So, we have that the relative error is equal to 2.5%.

Hence, we have that:

[tex]AbsoluteError=20mhz[/tex]

[tex]RelativeError=2.5(Percent)[/tex]

Have a nice day!

Absolute error is 20 MHz and relative error is 2.5%.

Absolute error: Absolute error is the difference between the measured value and the actual value. In this case, the absolute error is 820 MHz - 800 MHz = 20 MHz.

Relative error: Relative error is the ratio of the absolute error to the actual value. The relative error can be calculated as (820 MHz - 800 MHz) / 800 MHz = 0.025 or 2.5%.

Answer:

the desired result is (p + q) = (3 + 5) = 8

Step-by-step explanation:

Let's solve this system of linear equations in the usual way:  find the values of p and q.  Then find (p + q) as a numerical result.

Solve:

2p+q=11

p+2q=13

Multiply the second equation by -2:

2p + q = 11

-2p - 4q = -26

Combining these two equations results in -3q = -15, and so q must be 5.

Subbing 5 for q in the first equation, we get:

2p + 5 = 11, or 2p = 6.  Then p = 3.

Then the desired result is (p + q) = (3 + 5) = 8

The required answer is  p + q is equal to 8 by  solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.

To find the value of p + q, we can use the given system of equations:

Equation 1: 2p + q = 11

Equation 2: p + 2q = 13

We can solve this system of equations by either the substitution method or the elimination method. Let's use the elimination method:

Multiply Equation 1 by 2:

2(2p + q) = 2(11)

4p + 2q = 22 ...(Equation 3)

Subtract Equation 2 from Equation 3:

(4p + 2q) - (p + 2q) = 22 - 13

4p + 2q - p - 2q = 9

3p = 9

Divide both sides by 3 to solve for p:

p = 9 / 3

p = 3

Now substitute the value of p back into Equation 1:

2(3) + q = 11

6 + q = 11

Subtract 6 from both sides to solve for q:

q = 11 - 6

q = 5

Finally, we can find p + q:

p + q = 3 + 5

p + q = 8

Therefore, p + q is equal to 8 solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.

You must make a [tex]\frac{part}{whole}[/tex] proportion.

92% is part of 100%

540 would need to be the 92% of the plant bought. That means 540 is the part and the whole would be the unknown (let's make this x)

Set up your proportion like so...

[tex]\frac{540}{x} =\frac{92}{100}[/tex]

Cross multiply...

92x = 540 * 100

92x = 54000

Isolate x by dividing 92 to both sides...

92x/92 = 54000/92

x = 586.9565

Since you can't buy a decimal of a plant you will have to round this number up to the next whole number...

Answer:

The inequality would be 4x + 9 ≥ 0

Step-by-step explanation:

You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.

For this case we have a function of the form [tex]y = f (x)[/tex], where:

[tex]f (x) = \sqrt {4x + 9} +2[/tex]

We must look for the domain of the function. By definition, the domain of a function is given by all the values for which the function is defined.

So, for the given function to be defined, the argument of the root must be positive, that is:

Answer:

Step-by-step explanation:

point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.

Answer:

B.

Step-by-step explanation:

The answer is B. The problem says that the slope is 2 and it as the points (3,10) on its line. When looking at the graph, you can see that the line crosses at four on the y-intercept which is why four will be your constant. So, your equation in slope intercept form will become y=2x+4. With this, you can start eliminating the given answers.

You can immediately eliminate c and d because the 2 is negative when it isn't in its slope form. It leaves you with a and b.

When looking at both a and b you now have to look at what your y will become when you sinplify both of them. In choice a, the 2 multiplies with the 3 and gives you 6. Since you have to leave the y by itself you have to subtract 10 from both sides which will leave you with -4. Since your y-intercept isn't negative you know that a isnt the ansewr.

When checking b, you multiply the 2 and -3 to get -6. Since you have to leave the y by itself, you add 10 to each side and end up with 4 which is the same number that crosses the y-axis. and that is how you know it's the right answer.

Your answer is B) -1/2

One way of finding this answer is by using the slope equation (y2 - y1)/(x2 - x1) and substituting in the coordinates on the line. This gets you

(2 - 3)/(4 - 2) = -1/2

Another way is to find the slope by looking at the graph, and seeing that it must be negative because it slopes downwards to the right instead of up, and that it must be 1/2 because for every 1 unit you go down, you go 2 across, which means your y/x is 1/2.

measurement will tell him the minimum amount of wood that he will need to build the frame by the perimeter of the painting

The correct option is (A).

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.

As Arjun need to build the frame for the painting.

For framing  or fencing we generally use the concept of Perimeter.

For example,

Let us consider an example.

David wants to put a fence around his farm so that his sheep will not wander away.

He wants to know how much wire he would need to fence around his farm.

The shape of the field is rectangular.

Now, if we add the distance of all 4 sides of his farm, it will give us the perimeter.

By observation, we can see that the slope of the graph is negative (i.e the graph goes from top left to bottom right) hence the number attached to the x-term must be negative. We can see that E and F have positive x-terms, hence these cannot be correct.

Step-by-step explanation:

d  ≥ 1/2.

The Inequality represents all possible solutions of -12 d ≥ (-6) is d ≤ 1/2.

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

We have the inequality,

-12 d ≥ (-6).

Now, solving the inequality

Divide both side by 12

(-12 d )/ 12 ≥ (-6)/ 12

-d ≥ -1/2

The slope of the airplane's ascent is calculated using the rise over run formula and is 3 / 8 or 0.375.

Explanation:

The slope of the airplane's ascent can be calculated by the ratio of the rise over the run. In this case, the airplane climbs 15 feet up (rise) for every 40 feet it moves forward (run). Therefore, using the formula slope = rise / run, we can determine that the slope of the airplane's ascent is 15 / 40, which simplifies to 3 / 8 or 0.375.
