Which of the equations below could be the equation of this parabola?

Effectus [21]

A vertical parabola is: y = a(x-h)² + k
where (h,k) is the vertex and "a" is the vertical stretch/shrink.
A negative sign in front of the "a" represents a reflection over the x-axis.

y = a(x-0)² + 0
y = a(x)²
Answer: B (y = 3x²)

What equation is equivalent to P = mgh, but solved for Y? **please explain**

Elan Coil [88]

Potential energy = mass * acceleration due to gravity ( $9.8m/s^2$ ) * height

$P = mgh$
$P/mg = mgh/mg$
$P/mg = h$

Color blindness is an inherited characteristic that is more common in males than females. Let F represent female, and C represen

malfutka [58]

Answer:

0.513 = 51.3% probability of being a female.

Step-by-step explanation:

We are given the following formula:

$P(F \cup C) = P(F) + P(C) - P(F \cap C)$

In which:

Event F: Female

Event C: Red-green color blindness.

Probability of a Female

We have to find P(F), which is given by:

$P(F) = P(F \cup C) + P(F \cap C) - P(C)$

We are given by:

$P(C) = 0.039, P(F \cap C) = 0.004, P(F \cup C) = 0.548$

$P(F) = P(F \cup C) + P(F \cap C) - P(C) = 0.548 + 0.004 - 0.039 = 0.513$

0.513 = 51.3% probability of being a female.
