use the discriminant to describe the roots of each equation. then select the best description. x2 9x 14 = 0

1 answer:

4 0

Discriminant = b^2 - 4ac; where a = 1, b = 9 and c = 14
d = (9)^2 - 4(1)(14)
d = 81 - 56
d = 25

the discriminant is greater than zero, so there are two real roots

What is the mean of this data set? {6, 11, 5, 2, 7} Enter your answer as a decimal in the box.

Elenna [48]

Answer:

The mean is 6.2.

Step-by-step explanation:

The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.

So:

Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31

You find the average by dividing the sum of the terms (31) by the number of terms (5).

31/5 = 6.2

The mean is 6.2.

I hope this helped! :)
