The events A and B are independent events, and the values of P(A) and P(B) are 7/12 and 1/2, respectively

<h3>The value of P(A)</h3>

The event A is given as:

A : Sum greater than 6

In the sample space of a roll of two dice, there are 21 outcomes that are greater than 6, out of a total of 36 outcomes

This means that:

P(A) = 21/36

Simplify

P(A) = 7/12

<h3>The value of P(B)</h3>

The event B is given as:

B : Sum is divisible by 2

In the sample space of a roll of two dice, there are 18 outcomes that are divisible by 2, out of a total of 36 outcomes

This means that:

P(B) = 18/36

Simplify

P(B) = 1/2

Hence, the probability values of P(A) and P(B) are 7/12 and 1/2, respectively

How do I find the diameter and circumference when given the area?

JulijaS [17]

Hello from MrBillDoesMath!

Answer:

Diameter = 2r = 2 (sqrt(24/Pi))

Circumference = 4 sqrt(6Pi)

Discussion:

Given:

Area of circle = Pi r^2

24 = Pi r^2 => (as Pi r^2 is the formula for area of a circle)

24/Pi = r^2 => ( now take the square root of both sides)

r= sqrt(24/Pi)

Diameter = 2r = 2 (sqrt(24/Pi))

Circumference = 2 PI r = 2Pi (sqrt(24/Pi))

= 2Pi (sqrt(24)/sqrt(Pi) )

= 2Pi (2sqrt(6)/sqrt(Pi) )

= 4 (pi/ sqrt(Pi) ) sqrt(6)

= 4 sqrt(Pi) sqrt(6)

= 4 sqrt(6Pi)

Thank you,

MrB

jeordie spreads out a recctangular picnic blanket with an area of 42 square feet. its width is 6 feet . which equation coud you

DochEvi [55]

Answer:

6x = 42

Step-by-step explanation:

The formula to find the area of a rectangle is $A = LxW$ . Since we have a value for the width, we simply need to find what to multiply to 6 to get 42.

Let x = length

6x = 42

We then divide both sides by 6 to find the value of x.

$\dfrac{6x}{6}=\dfrac{42}{6}$

$x=7$

So we know the length is 7.

To check the answer we substitute x with 7.

$6(7)=42$

$42=42$
