CD has endpoints C(6,-8) and D(-4,10) on a coordinate plane. What are the coordinates of the midpoint CD

Answers

Final answer:

The midpoint of the line segment with endpoints C(6,-8) and D(-4,10) is calculated to be at (1, 1) by averaging the x and y coordinates of the endpoints.

Explanation:

The midpoint of a line segment with endpoints C(6,-8) and D(-4,10) can be found by averaging the x-coordinates and the y-coordinates of the two endpoints. To do this, add together the x-coordinates, 6 and -4, and divide by 2 to find the x-coordinate of the midpoint. Add together the y-coordinates, -8 and 10, and divide by 2 to find the y-coordinate of the midpoint.

The calculations are as follows:
x-coordinate: (6 + (-4)) / 2 = 1
y-coordinate: (-8 + 10) / 2 = 1

Therefore, the midpoint of CD is (1, 1).

In a Budget Plan, Fixed Expenses were $475. They have gone up 5%. What will the updated Total Fixed Expenses be?
a) $469.25

select all the points that are solutions to the system of linear inequalities that is listed below 10x + 4y < 12
8x - 3y > 20
. (3, -8) (2, 5) (-5, 1) (10, 3) (2, -10)

Answers

Answer:

(3,-8)

(2,-10)

Step-by-step explanation:

we have

[tex]10x + 4y < 12[/tex] ----> inequality A

[tex]8x- 3y > 20[/tex] ----> inequality B

we know that

If a point is a solution of the system of inequalities, then the point must satisfy both inequalities (makes true both inequalities)

Verify  all the points

Substitute the value of x and the value of y of each point in both inequalities  

Case 1) point (3,-8)    

For x=3, y=-8

inequality A

[tex]10(3) + 4(-8) < 12[/tex]

[tex]-2 < 12[/tex] ----> is true

inequality B

[tex]8(3)- 3(-8) > 20[/tex]

[tex]48 > 20[/tex] ---> is true

therefore

The point is a solution of the system of linear inequalities

Case 2) point (2,5)    

For x=2, y=5

inequality A

[tex]10(2) + 4(5) < 12[/tex]

[tex]40 < 12[/tex] ----> is not true

therefore

The point is not a solution of the system of linear inequalities

Case 3) point (-5,1)    

For x=-5, y=1

inequality A

[tex]10(-5) + 4(1) < 12[/tex]

[tex]-46 < 12[/tex] ----> is true

inequality B

[tex]8(-5)- 3(1) > 20[/tex]

[tex]-43 > 20[/tex] ---> is not true

therefore

The point is not a solution of the system of linear inequalities

Case 4) point (10,3)    

For x=10, y=3

inequality A

[tex]10(10) + 4(3) < 12[/tex]

[tex]112 < 12[/tex] ----> is not true

therefore

The point is not a solution of the system of linear inequalities

Case 5) point (2,-10)    

For x=2, y=-10

inequality A

[tex]10(2) + 4(-10) < 12[/tex]

What number is 21% more than 5/11?

Answers

Answer:

Step-by-step explanation:

21% more then 5/11...

5/11 + 21% of 5/11 = 5/11 + 0.21(5/11) = 5/11 + (21/100 * 5/11) =

5/11 + 21/220 = 11/20 <===

Final answer:

Firstly, we converted the fraction 5/11 to its decimal equivalent, which is approximately 0.4545. Then, we calculated a number that is 121% of 0.4545 (because 21% more than the original number means we have to count the original number plus the additional 21%). The calculation gave us approximately 0.5499.

Explanation:

To answer this question, we can firstly calculate the equivalent decimal of 5/11. This can be done either by manual calculation or using a calculator. Dividing 5 by 11, we get approximately 0.4545.

Next, it's important to understand what the question is asking. When it asks what number is 21% more than a given number, it's essentially asking you to calculate a number that is 121% of the given number. Why? Because the original number (100%) plus the additional 21% gives you a total of 121%.

Once you know this, you simply multiply the given number (0.4545) by 1.21 (the decimal equivalent of 121%). And finally, multiplying 0.4545 by 1.21, we get approximately 0.5499. That is your final answer: The number that is 21% more than 5/11 is approximately 0.5499.

Let f(x) be a continuous function such that f(1) = 3 and f '(x) = sqrt( x^3 + 4 ). What is the value of f(5)?

Answers

The value of f(5) is 49.1

Step-by-step explanation:

To find f(x) from f'(x) use the integration

f(x) = ∫ f'(x)

1. Find The integration of f'(x) with the constant term

2. Substitute x by 1 and f(x) by π to find the constant term

3. Write the differential function f(x) and substitute x by 5 to find f(5)

∵ f'(x) =  + 6

- Change the root to fraction power

∵  =

∴ f'(x) =  + 6

∴ f(x) = ∫  + 6

- In integration add the power by 1 and divide the coefficient by the

 new power and insert x with the constant term

∴ f(x) =  + 6x + c

- c is the constant of integration

∴ f(x) =   + 6x + c

- To find c substitute x by 1 and f(x) by π

∴ π =   + 6(1) + c

∴ π =  + 6 + c

∴ π = 6.4 + c

- Subtract 6.4 from both sides

∴ c = - 3.2584

∴ f(x) =   + 6x - 3.2584

To find f(5) Substitute x by 5

∵ x = 5

∴ f(5) =   + 6(5) - 3.2584

∴ f(5) = 49.1

Given that the percentage of physicians who are women is 27.9%. In a survey of physicians employed by a large  university health system,

45 of 120 randomly selected physicians were women.

Sample size n = 120

Sample proportion p = [tex]\frac{45}{120} \\=0.375[/tex]

H0: p = 0.279

The Undergraduate grade point average (UGPA) of students taking the Law School Admissions Test in recent year can be approximated with a normal distribution with mean=3.36 and standard deviation=.18

what is the minimum UGPA that will place a student in the top 10%?

Answers

Answer:

[tex]a=3.36 +0.816*0.18=3.507[/tex]

The value of height that separates the bottom 90% of data from the top 10% is 3.507.  

Step-by-step explanation:

1) Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

2) Solution to the problem

Let X the random variable that represent the grades of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(3.36,0.18)[/tex]  

Where [tex]\mu=3.36[/tex] and [tex]\sigma=0.18[/tex]

And the best way to solve this problem is using the normal standard distribution and the z score given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

For this part we want to find a value a, such that we satisfy this condition:

[tex]P(X>a)=0.10[/tex]   (a)

[tex]P(X<a)=0.90[/tex]   (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.90 of the area on the left and 0.10 of the area on the right it's z=0.816. On this case P(Z<0.816)=0.90 and P(Z>0.816)=0.1

If we use condition (b) from previous we have this:

[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.90[/tex]  

[tex]P(z<\frac{a-\mu}{\sigma})=0.90[/tex]

But we know which value of z satisfy the previous equation so then we can do this:

[tex]z=0.816=\frac{a-3.36}{0.18}[/tex]

And if we solve for a we got

[tex]a=3.36 +0.816*0.18=3.507[/tex]

So the value of height that separates the bottom 90% of data from the top 10% is 3.507.  

Final answer:

To find the minimum Undergraduate grade point average (UGPA) that would place a student in the top 10%, we use the Z-score corresponding to the top 10% (which is about 1.28) and apply it within the normal distribution parameters, mean (3.36) and standard deviation (.18). The result is a UGPA of approximately 3.59.

Explanation:

This question pertains to the concept of normal distribution in statistics. Given a mean of 3.36 and a standard deviation of .18, we're asked to find the minimum Undergraduate grade point average (UGPA) that would place a student in the top 10%. This requires the understanding of Z-scores (standard deviations away from the mean).

The Z-score that corresponds to the top 10% in a standard normal distribution is about 1.28 (this value comes from a standard Z-table or can be calculated using a statistical calculator). Remember that the Z-score formula is Z = (X - μ) / σ, where X is the value we're looking for, μ is the mean, and σ is the standard deviation.

So, rearranging the formula to solve for X gives X = Z*σ + μ. Substituting the known values into the equation gives: X = (1.28*.18) + 3.36, which gives X approximately equal to 3.59. Therefore, the minimum UGPA that will place a student in the top 10% is approximately 3.59.

If there is 1000$ in the lockbox what year will it be worth 64,000$ at 24% interest?

Hey there!

First, set up an exponential equation that represents the rate at which your original amount, 1000, gains interest:

y = 1000(1.24)^x

Y represents the value after X years. 1.24 represents the rate at which the money gains interest, 1 + 0.24 (your 24% interest rate in decimal form). 1000 is your original amount.

Now, set this equation equal to 64000, graph y = 64000 and y = 1000(1.24)^x on a graphing calculator, and see where the two equations intersect in order to solve for x.

They intersect when x is about 19.334, as seen in the graph below (it is very zoomed in so that you can see where the two functions intersect). Therefore, it will be about 19 years after the year in which you deposited the 1000 dollars before the money is worth 64000 dollars.

Answers

Answer:

Cost of each Computer is $225 and Cost of each Printer is $150.

Step-by-step explanation:

Let the cost of the Computers be 'x'.

Let the cost of Printer be 'y'.

Given:

If he buys three computers and one printer, the cost is $825.

framing in equation form we get;

[tex]3x+y =825 \ \ \ \ \ equation\ 1[/tex]

Also Given:

if he buys 4 computers and 2 printers, the cost is $1200.

framing in equation form we get;

[tex]4x+2y =1200 \ \ \ \ \ equation\ 2[/tex]

Now Multiplying equation 1 by 2 we get;

[tex]2(3x+y)=825\times 2\\\\6x+2y=1650 \ \ \ \ \ equation\ 3[/tex]

Now Subtracting equation 2 from equation 3 we get;

[tex](6x+2y)- (4x+2y) = 1650-1200\\\\6x+2y-4x-2y = 450\\\\2x=450\\\\x=\frac{450}{2} =\$225[/tex]

Now Substituting the value of x in equation 1 we get;

[tex]3x+y=825\\\\3\times 225+y=825\\\\675+y =825\\\\y = 825 -675\\\\y = \$150[/tex]

AB = [tex]\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]

<=> AB = [tex]\sqrt{(1-1)^{2} +(4-(-1))^{2} }[/tex]

<=> AB = 5 units

Hope it will find you well.

Final answer:

The question relates to finding the distance between two points in a coordinate system. The length of the line segment connecting vertex A (1,-1) and vertex B (1,4) of the triangle ABC can be calculated using the distance formula, which yields a result of 5 units.

Explanation:

The subject of your question is geometry, specifically the concept of distance between two points in a coordinate system. In finding the length of the line segment that connects vertex A (1,-1) and vertex B (1,4), you can use the distance formula based on Pythagorean theorem.

The distance formula is d = sqrt [(x2 - x1)² + (y2 - y1)²]. In this case, x1 = 1, x2 = 1, y1 = -1 and y2 = 4.

Substituting these values, we have d = sqrt [(1 - 1)² + (4 - (-1))²] = sqrt [0 + 25], hence d = sqrt [25] = 5 units.

Therefore, the length of the line segment connecting vertex A (1, -1) and vertex B (1, 4) is 5 units.

Richard, Henry and Gavin share some sweets in the ratio 5:4:3. Richard gets 70 sweets. How many sweets are there altogether?

Answers

There are 168 sweets altogether

Solution:

Richard, Henry and Gavin share some sweets in the ratio 5 : 4 : 3

Let "5a" be the share of Richard

Let "4a" be the share of Henry

Let "3a" be the share of Gavin

Richard gets 70 sweets

share of Richard = 70

5a = 70

a = 14

To find: number of sweets altogether

number of sweets altogether = share of richard + share of henry + share of gavin

number of sweets altogether = 5a + 4a + 3a

number of sweets altogether = 12a = 12(14) = 168

Thus there are 168 sweets altogether
