If a set of exam scores forms a symmetrical distribution, then the student mean scores is the median and the mode too.

<h3>What is a Symmetrical distribution?</h3>

A symmetrical distribution by definition is the situation which occurs when the values of variables appear at regular frequencies and is characterized by the mean, median, and mode all occuring at the same point in most cases.

Graphically, symmetrical distributions may appear as a normal distribution (i.e., bell curve).

What the the distance between the points 6,2 and 1,2
yawa3891 [41]

The distance is given by:

\left(x_1,\:y_1\right) and \:\left(x_2,\:y_2\right)\rightarrow\left(6,\:2\right) and \:\left(1,\:2\right)

\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2} = \sqrt{\left(1-6\right)^2+\left(2-2\right)^2} = 5

F(x)=25x^2-10x+1 what is the the value of the discriminant of f ​
Elanso [62]

Answer:

0

Step-by-step explanation:

Quadratic equation

x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}

The discriminant is the part of the quadratic formula within the square root symbol: {b^{2}-4*a*c}.  The discriminant indicates if there are two solutions, one solution, or none.

The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.

So, a positive discriminant tell us that the quadratic has two different real solutions.

A discriminant of zero tell us that the quadratic has two real and equal solutions.

And a negative discriminant tell us that none of the solutions are real numbers.

In this case: 25x^2-10x+1=0

We can see that

a= 25    b=-10   c=1

Using:  {b^{2}-4*a*c}

We have  -10^{2}-4* 25*1 =100-100=0

the answer is zero, so the quadratic has two real and equal solutions

What is the range of f(x)=e^x?
Tanzania [10]
The range refers to the value of y for which x is define.

So let y=f(x),

y =  {e}^{x}

Try making x the subject to obtain,

x =  ln(y)
x is defined for all real values of y greater than
0.

Hence the correct answer is D.
