Answer:

3 / 10

Step-by-step explanation:

The required outcome = mexico ; number of spins = 6 spins

Total possible outcomes = sum. Of all spins = (6 + 4 + 5 + 5) = 20

P(Mexico on next spin) = required outcome / Total possible outcomes

P(Mexico on next spin) = 6 / 20 = 3 / 10

Will someone explain what i did wrong here?

The actual inverse function is:

$f^{-1}(x) = x^2 + 3$

And the domain is [0, ∞).

<h3>Where is the mistake?</h3>

Remember that for a given function f(x) with a domain D and a range R.

For the inverse function, f⁻¹(x) the domain is R and the range is D.

Here, for the given function the domain is x ≥ 3 and the range is [0, ∞).

Then for the inverse function, which is:

$f^{-1}(x) = x^2 + 3$

(to check this, you must have that):

$f^{-1}(f(x)) = x\\\\f(f^{-1}(x)) = x$

The domain will be [0, ∞) and the range x ≥ 3

I have one third gallon of juice and one sixth gallon. How many more gallons is need to make three gallons

charle [14.2K]

Answer:

2.5 gallons

Step-by-step explanation:

Make the denominators of the fractions the same and combine them

$\frac{1}{3} =\frac{2}{6}$

$\frac{2}{6} +\frac{1}{6} =\frac{3}{6}$

Then simplify the fraction

$\frac{3}{6} =\frac{1}{2}$

Then subtract how many gallons you have from how many you want

$3 -\frac{1}{2} = 2\frac{1}{2}$

You will need 2.5 gallons to make 3 gallons
