Let's call the animals "a" and birds "b"

b=\frac{3}{28}a

we knot this from3/28 of the animals are birds.

and we also know that 4/15 are birds of prey.  so

p=\frac{4}{15}b

we could substitute:

p=\frac{4*3}{15*28}

and solve:

p=\frac{1}{35}
and this is the answer!

State the value of the discriminant of -6x^2 +2x + 3 = 0
Dmitry [639]

Answer:

76

Step-by-step explanation:

recall that for a quadratic equation in the form

ax² + bx + c = 0, the discriminant is given by

discriminant, D = b²- 4ac

we are given the following:

-6x² + 2x + 3 = 0,

comparing this with the general equation above, it is clear that,

a = -6, b = 2 and c = 3,

substituting these into our equation for discriminant:

D = b²- 4ac

= 2² - 4(-6)(3)

= 4 + 72

= 76
