Which measure is always the 50th percentile?
mean
median
upper quartile

Answers

Answer 1
Answer:

The measure that always represents the 50th percentile is the median. It is the middle value when data is sorted and is robust to outliers, unlike the mean.

The measure that always represents the 50th percentile in a dataset is the median. The median is the middle value in a dataset when it is ordered from smallest to largest. It divides the data into two equal halves, with half of the values falling below it and half above it.

Unlike the mean, which is the average of all values and can be influenced by extreme outliers, the median is robust to outliers because it solely depends on the middle value. This makes it a better measure of central tendency when dealing with skewed or non-normally distributed data.

On the other hand, the upper quartile, also known as the third quartile, represents the 75th percentile. It divides the data into the upper 25% and lower 75%. The mean is the average of all values in the dataset and does not necessarily correspond to any specific percentile.

In summary, the median always corresponds to the 50th percentile and is a valuable measure for understanding the central tendency of a dataset, especially when dealing with skewed data or outliers, while the mean and upper quartile represent different points in the data distribution.

The resquest of the y'+6y=e^4t, y(0)=2

Answers

This is a linear differential equation of first order. Solve this by integrating the coefficient of the y term and then raising e to the integrated coefficient to find the integrating factor, i.e. the integrating factor for this problem is e^(6x). 
Multiplying both sides of the equation by the integrating factor: 

(y')e^(6x) + 6ye^(6x) = e^(12x) 

The left side is the derivative of ye^(6x), hence 

d/dx[ye^(6x)] = e^(12x) 

Integrating 

ye^(6x) = (1/12)e^(12x) + c where c is a constant 

y = (1/12)e^(6x) + ce^(-6x) 

Use the initial condition y(0)=-8 to find c: 

-8 = (1/12) + c 
c=-97/12 

Hence 

y = (1/12)e^(6x) - (97/12)e^(-6x)

8 1/4 pounds of flour are used to make 4 1/8 papier-mâché pasta recipe how much flour is used in one recipe

Answers

2 pounds of flour are required to make 1 recipe, as of the given condition.

Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.

Thus,  2 pounds of flour are required to make 1 recipe, as of the given condition.

Quadrilateral ABCD is inscribed in a circle. m A is 64°, m B is (6x + 4)°, and m C is (9x - 1)°. What is m D?A. 64°
B. 82°
C. 90°
D. 98°
E. 116°

Answers

Answer: Choice D) 98 degrees

============================================================

Explanation:

The quadrilateral is inscribed in the circle which means every corner point (A,B,C,D) is on the circle. No part of the quadrilateral is outside the circle. 

One property of inscribed quadrilaterals is that the opposite angles add to 180 degrees. So,
A+C = 180
B+D = 180

We know that
A = 64
B = 6x+4
C = 9x-1

Let's use angles A and C to find x
A+C = 180
64+9x-1= 180
9x+63 = 180
9x+63-63 = 180-63
9x = 117
9x/9 = 117/9
x = 13

Which helps us find angle B
B = 6x+4
B = 6*13+4
B = 78+4
B = 82 degrees

Then we can finally find angle D
B+D = 180
82+D = 180
82+D-82 = 180-82
D = 98 degrees

Answers

I don't know if you know something called PEMDAS

Parentheses
Exponent
Multiply
Divide
Add
Subtract

So you would do the -2(-7) first giving you 14

So now we have -62/12 +14

now you would do -62/12 giving you -5.16666667

and now the equation is -5.16666667 + 14 = 8.83333333

I know for a fact, being in Calculus Honors, that what I did to simplify is correct. Using the Order of Operations, or PEMDAS (Commonly remebered as "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".) to simplify this answer is necessary.

If your teacher wrote this problem please inform him or her of Order of Operations before your classmates use it even though its wrong.

Please I REALY NEED HELPTriangle ABC is similar to triangle LMN by the AA Similarity Postulate.

Also, m∠A = 108° and m∠C = 2(m∠M).

What is m∠M?

_________ °

Answers

since two of the triangles are similar that means they are the same thing : 
<A = <L
108 = 108

<C is twice from <M so :
<C is 2x                 < M is x             


as you note down the answer you can draw two triangles and label them according to thier values,  you will see that triangle ABC has two things now  ;
                                                           a = 108   and   c = 2x
when you have two measures in a triangle you can find the 3rd one :
suppose that third < of  triangle ABC is x ;
108 + 2x + x = 180
108 + 3x = 180
 3x = 180 - 108 
 3x = 72 
  x = 24
                
                                          <m = 24 

further if you want to find C :
                                          < c = 2x 
                                      < c = 2 ( 24 ) 
                                       < c = 48
