Answer:

$b)\ 0.568$

Step-by-step explanation:

Given

$f(x) = 6x(1- x);\ 0 \le x \le 1$

Required

$P(0.3 < x < 0.7)$

From the question, we have:

$P(a < x < b) = \int\limits^b_a {f(x)} \, dx$

So, we have:

$P(0.3 < x < 0.7) = \int\limits^{0.7}_{0.3} {6x(1 - x)} \, dx$

Open bracket

$P(0.3 < x < 0.7) = \int\limits^{0.7}_{0.3} {6x - 6x^2} \, dx$

Integrate

$P(0.3 < x < 0.7) = \frac{6x^2}{2} - \frac{6x^3}{3}}|\limits^{0.7}_{0.3}$

$P(0.3 < x < 0.7) = 3x^2 - 2x^3|\limits^{0.7}_{0.3}$

Substitute 0.7 and 0.3 for x

$P(0.3 < x < 0.7) = (3*0.7^2 - 2*0.7^3) - (3*0.3^2 - 2*0.3^3)$

Using a calculator, we have:

$P(0.3 < x < 0.7) = (0.784) - (0.216)$

Remove brackets

$P(0.3 < x < 0.7) = 0.784 - 0.216$

$P(0.3 < x < 0.7) = 0.568$

The weight of the circle that is double the weight of the triangle is 20 grams.

<h3>How to find weight ?</h3>

The weight of the rectangle is 80 grams.

The weight of the triangle is double the weight of the weight of the circle.

A rectangle is made up of 2 triangles. Therefore,

weight of each triangle = 80 / 2 = 40 grams

Since, the weight of the triangle is double the weight of the circle, the weight of the circle can be calculated as follows:

weight of circle = 40 / 2

Therefore,

weight of the circle = 20 grams.

Answer:

The last two options.

Step-by-step explanation:

y=2x+4 (replace the x with 1) y=2(1)+4 Y=6

y= 2x+4 replace the x with 2) y= 2(2)+4 Y= 8

So the y coordinate can be 6 or 8.
