If the average(arithmetic mean) of 5 and r is 7 and the average of 3 and s is 3 , what is the average of r and s?
Norma-Jean [14]

Answer:

C

Step-by-step explanation:

Calculate the values of both r and s, that is

\frac{5+r}{2} = 7 ( multiply both sides by 2 )

5 + r = 14 ( subtract 5 from both sides )

r = 9

and

\frac{3+s}{2} = 3 ( multiply both sides by 2 )

3 + s = 6 ( subtract 3 from both sides )

s = 3

Hence

\frac{9+3}{2} = \frac{12}{2} = 6 → C

What is the value of the discriminant, b2 − 4ac, for the quadratic equation 0 = x2 − 4x + 5, and what does it mean about the num
sleet_krkn [62]

Answer:

The discriminant is −4, so the equation has no real solutions.

Step-by-step explanation:

In the equation 0 = x² - 4x + 5, a is 1, b is -4, and c is 5.

Plug in these values into b² - 4ac, and simplify:

b² - 4ac

(-4)² - 4(1)(5)

16 - 20

= -4

So, the discriminant is -4. This means that the equation has no real solutions, because the discriminant is a negative number.

The correct answer is that The discriminant is −4, so the equation has no real solutions.
