Solve the system if possible by using Cramer's rule. If Cramer's rule does not apply, solve the system by using another method.

maks197457 [2]

Answer:

D = 0 , Dx = 4 , Dy = -6 , Dz = 2

Step-by-step explanation:

As per<u> cramer's rule</u>,

D = | 7 6 4 | = 0

| 3 3 3 |

| 4 4 4 |

Dx = | 10 6 4 | = 4

| 1 3 3 |

| 2 4 4 |

Dy = | 7 10 4 | = -6

| 3 1 3 |

| 4 2 4 |

Dz = | 7 6 10 | = 2

| 3 3 1 |

| 4 4 2 |

if a pair of standard dice are rolled what is the probability that one die shows a six but not both of them. reduced fraction an

Novay_Z [31]

Answer:

$P=\frac{5}{18}$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x------> size of the event space

y-----> size of the sample space

if a die is rolled the sample space is

$\{1,2,3,4,5,6\}$

if two dice rolled the sample space is

$\{1,2,3,4,5,6\}*\{1,2,3,4,5,6\}$

so

The possible pairs are

$y=6*6=36$

The size of the event space x is

$\{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)\}$

$x=10$

$P=\frac{x}{y}$

substitute

$P=\frac{10}{36}$

Simplify

$P=\frac{5}{18}$

Find the exact volume of a cone 6yd height 5yd base

Verdich [7]

Answer:

The exact volume of a cone is 10 yd³.

Step-by-step explanation:

Given:

Height of cone (h) is 6 yd and base (b) is 5 yd.

Now, to get the volume we need to find the radius.

So, to find radius we put the formula of base:

Let the radius be $r$

Base= $\pi r^2$

$b=\pi\times r^{2}$

$5=\pi\times r^{2}$

Dividing both sides by π and using square root on both the sides:

$5\div \pi=(\pi \times r^{2}) \div \pi$

$\frac{5}{\pi}=r^{2}$

$r^{2}=\frac{5}{\pi}-----1$

Now, putting the formula for getting the volume (v) of cone:

Volume = $\pi r^2\frac{h}{3}$

$v=\pi\times r^{2}\times \frac{6}{3}$

$v=\pi\times r^{2}\times 2$

Substituting the value of $r^2$ from equation (1), we get:

$v=\pi\times \frac{5}{\pi}\times 2$

$v=10$ yd³

Volume of cone is 10 yd³

Therefore, the exact volume of a cone is 10 yd³.
