Answer: 22

Step-by-step explanation: To find the average of this data set, remember that the average of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

So to find the average of the data set shown here, let's begin by adding the numbers.

So we have 18 + 21 + 19 + 25 + 24 + 25.

This will be divided by how many numbers are in the set which is 6.

So we have \frac{18 + 21 + 19 + 25 + 24 + 25}{6}

Adding the numbers, we get 132.

So we have \frac{132}{6} which simplfies to 22.

So the average of this data set is 22.

Answer: The average is 22

Step-by-step explanation: To calculate any average from a database like this one, add all the numbers to find your total, which in this case would be 132. Then divide the total by however many numeric values you had to add, which would be 6. This gives you your final equation, (132 divided by 6 = 22).

For a given function ƒ(x) = x2 – x + 1, the operation –ƒ(x) = –(x2 – x + 1) will result in a
Mekhanik [1.2K]

Given:

The function is:

f(x)=x^2-x+1

To find:

The result of the operation -f(x)=-(x^2-x+1).

Solution:

If g(x)=-f(x), then the graph of f(x) is reflected across the x-axis to get the graph of g(x).

We have,

f(x)=x^2-x+1

The given operation is:

-f(x)=-(x^2-x+1)

So, it will result in a reflection across the x-axis.

Therefore, the correct option is A.

Substitute the values for a, b, and c into b2 – 4ac to determine the discriminant. Which quadratic equations will have two real
hoa [83]

Answer: 0=2x^2-7x-9\\0=4x^2-3x-1\\0=x^2-2x-8


Step-by-step explanation:

We know that the standard quadratic equation is  ax^2+bx+c=0

Let's compare all the given equation to it and , find discriminant.

1. a=2, b= -7, c=-9

b^2-4ac=(-7)^2-4(2)(-9)=49+72>0

So it has 2 real number solutions.

2. a=1, b=-4, c=4

b^2-4ac=(-4)^2-4(1)(4)=16-16=0

So it has only 1 real number solution.

3. a=4, b=-3, c=-1

b^2-4ac=(-3)^2-4(4)(-1)=9+16=25>0

So it has 2 real number solutions.

4. a=1, b=-2, c=-8

b^2-4ac=(-2)^2-4(1)(-8)=4+32=36>0

So it has 2 real number solutions.

5. a=3, b=5, c=3

b^2-4ac=(5)^2-4(3)(3)=25-36=-9

Thus it does not has real solutions.
