We wil use the density function of the uniform distribution:
f(x)=\dfrac{1}{b-a}\int_a^xdy
Using the given values: a=8,b=12, w get:
P(13\leq X\leq15)=\dfrac{1}{12-8}\int_{13}^{15}dy\\
=\dfrac{1}{12-8}*0=0
the probability is zero then.

The volume of a sphere is 4/3pi cm^3<br> what is the diameter of the sphere?
aleksandrvk [35]

The Diameter of sphere is 2cm.

Step-by-step explanation:

Given,

Volume of sphere = \frac{4}{3}\pi \ cm^3

Let,

diameter = d

As we know,

Volume of sphere = \frac{4}{3}\pi \ r^3

Therefore,

\frac{4}{3}\pi\ r^3 = \frac{4}{3}\pi \\Multiplying\ both\ sides\ by\ \frac{3}{4\pi }\\\frac{3}{4\pi }*\frac{4}{3}\pi \ r^3 = \frac{4}{3}\pi * \frac{3}{4\pi }\\r^3=1\\(r)^3=(1)^3\\r=1

We know that,

Diameter = 2r

Diameter = 2*1

Diameter = 2 cm

The Diameter of sphere is 2cm.

Answer:

A = 3

B = -5

C = 2

Step-by-step explanation:

The way to format a quadratic equation is: ax^2 + bx + c, so the first step to solving this is to format it in the right way, where the x^2 comes first, the x second, and the number alone.

After formatting, your equation should look like this: 3x^2 - 5x + 2

From here, you can see the the <em>a </em> is 3, the <em>b</em> is -5, and the <em>c </em>is 2
