Mark rolls two number cubes. What is the probability that the sum of the two numbers will equal 10?

1 answer:

4 0

There are 6×6=36 possible chance.
4+6=10
5+5=10
6+4=10.
As a result, the probability that the sum of the two numbers will equal 10 is 3/36 or 1/12 which is C. Hope it help!

Hello I need help Finding the probability

Each petal of the region $R$ is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length $5\sqrt2$ , which implies the segment is subtended by an angle of $\dfrac\pi2$ . This means the area of the segment is

$\text{area}_{\text{segment}}=\text{area}_{\text{sector}}-\text{area}_{\text{triangle}}$
$\text{area}_{\text{segment}}=\dfrac{25\pi}4-\dfrac{25}2$

This means the area of one petal is $\dfrac{25\pi}2-25$ , and the area of $R$ is four times this, or $50\pi-100$ .

Meanwhile, the area of $G$ is simply the area of the square minus the area of $R$ , or $10^2-(50\pi-100)=200-50\pi$ .

So

$\mathbb P(X=R)=\dfrac{50\pi-100}{100}=\dfrac\pi2-1$
$\mathbb P(X=G)=\dfrac{200-50\pi}{100}=2-\dfrac\pi2$
$\mathbb P((X=R)\land(X=G))=0$ (provided these regions are indeed disjoint; it's hard to tell from the picture)
$\mathbb P((X=R)\lor(X=G))=\mathbb P(X=R)+\mathbb P(X=G)=1$

What is the solution to the equation? x = 1 x = 6 x = 12 x = 24

stiks02 [169]

Answer:

Option B is the correct option

solution,

$\sqrt{5x - 7} = \sqrt{3x + 5}$

Cancel the square roots on both sides

$5x - 7 = 3x + 5$

Add 7 to both sides

$5x - 7 + 7 = 3x + 5 + 7$

Simplify

$5x = 3x + 12$

Subtract 3x from both sides

$5x - 3x = 3x + 12 - 3x$

Simplify

$2x = 12$

Divide both sides by 2

$\frac{2x}{2} = \frac{12}{2}$

Simplify

$x = 6$

Hope this helps...

Good luck on your assignment..

A warehouse worker loads a cart with 14 boxes. The boxes have an average weight of 24 pounds. The worker picks up a new box and

Alex

Answer: 39 pounds

Step-by-step explanation:

At first, the warehouse worker loads a cart with 14 boxes and the boxes have an average weight of 24 pounds. The total weight of the boxes will be:

= 14 × 24

= 336 pounds

Since the worker picks up a new box and puts it on the cart and the average weight of the boxes is 25 pounds. It means that the boxes are now 15 and their total weight will be:

= 15 × 25

= 375 pounds

The weight of the new box will be:

= 375 - 336

= 39 pounds

Can someone please answer?? It is already late

Wittaler [7]

Answer:

Jonelle's

Step-by-step explanation:

Cube is made up of square faces. The sides of a square equal.

The general formula of volume= Area of base X the height of the object

The area of the base of a cube (square) is calculated with the formula: Length X Length = L to the power of 2.

The area of the base must be multiplied by the height of the object to get the volume.

*You already know that all the dimensions on a cube are equal.

Therefore, the height of the cube will be equal to the Length of the square.

Length to the power of two(this is the area of the base) X Length (the length is equal to the height because the object is a cube)

=Length to the power of three.
