2. How many real number solutions are there to the equation 0 =-3x2 + x - 4?
goblinko [34]

For this case we have the following quadratic equation:

-3x ^ 2 + x-4 = 0

Where:

a = -3\\b = 1\\c = -4

By definition, the discriminant of a quadratic equation is given by:

d = b ^ 2-4 (a) (c)

We have to:

d> 0: Two different real roots

dTwo different complex roots

d = 0: Two equal real roots

Substituting the values we have:

d = 1 ^ 2-4 (-3) (- 4)\\d = 1-48\\d = -47

So, we have two different complex roots

Answer:

Two different complex roots

ivann1987 [24]

Answer:96.97

Step-by-step explanation:

Given

mean height of women \mu _w=64

Standard deviation of height \sigma _w=2.82

mean height of men \mu _=69.3

Standard deviation of height \sigma _m=2.71

P\left ( X

P\left ( \frac{x-\mu _w}{\sigma _w}\right )

P\left ( Z

i.e. 0.9697=96.97 %
