Help!!!!!!!!!!!!!!!!!!!!!!!
Nataly [62]
Hello.

Firstly, let's isolate x on the equation:

\mathsf{f(x) = 3x + 3} \\ \\ \mathsf{y = 3x + 3} \\ \\ \mathsf{-3x = -y + 3} \\ \\ \mathsf{x = \dfrac{-y + 3}{3}}

Now, we can replace 'x' for 'y' and vice-versa:

\mathsf{f^{-1}(x) = \frac{-x + 3}{3}`}

Hope I helped.

The probability that a point chosen at random lies in the shaded region is 0.28

<h3>Calculating the area of a shaded region and probability</h3>

From the question, we are to find the probability that a point chosen at random lies in the shaded region.

The shaded region is a triangle.

The probability that a point chosen at random lies in the shaded region = Area of the triangle / Area of the circle

First, we will calculate the unknown side of the triangle

Let the unknown side be x.

Then, from the <em>Pythagorean theorem</em>, we can write that

12² = 6² + x²

144 = 36 + x²

x² = 144 - 36

x² = 108

x = √108

x = 6√3

From formula,

Area of a triangle = 1/2 × base × height

Area of the triangle = 1/2 × 6 × 6√3

Area of the triangle = 18√3 square units

Now, we will determine the area of the circle

Area of a circle = πr²

Where r is the radius

From the given information,

Diameter of the circle = 12

But,

Radius = Diameter / 2

Therefore,

r = 12/2

r = 6

Thus,

Area of the circle = 3.14 × 6²

Area of the circle = 113.04 square units

Now,

The probability that a point chosen at random lies in the shaded region = 18√3 / 113.04

The probability that a point chosen at random lies in the shaded region = 0.2758

The probability that a point chosen at random lies in the shaded region ≈ 0.28

Hence, the probability is 0.28

If a pound of rice flour costs $12, how many ounces can be bought for $6.90?
Viktor [21]

Answer:

9.2 ounce

Step-by-step explanation:

To do this, we divide $12 by 16 ounces, because there are 16 ounces in a pound:

12/16 = 0.75

Now, we need to find how many ounces can be bought for $4.80. To do this, we divide 6.90 by 0.75

=9.2 ounce
