If three prime numbers are randomly selected from the prime numbers less than 30 and no prime number can be chosen more than onc

Dmitry [639]

Answer:

C)30%

Step-by-step explanation:

Prime numbers less than 30 are given below

2,3,5,7,11,13,17,19,23,29

We have to find the probability that sum of three prime numbers selected will be even.

We know that

Sum of any three prime number except 2 will be odd.

Total prime numbers except 2=9

Total prime numbers=10

Probability:P(E)= $\frac{favorable\;cases}{total\;number\;of\;cases}$

Probability of getting sum of three prime numbers selected will be odd= $\frac{9C_3}{10C_3}$

$nC_r=\frac{n!}{r!(n-r)!}$

By using formula

Probability of getting sum of three prime numbers selected will be odd=P(E)= $\frac{\frac{9!}{3!6!}}{\frac{10!}{3!7!}}=\frac{9!}{3!6!}\times \frac{3!\times 7\times 6!}{10\times 9!}$

Probability of getting sum of three prime numbers selected will be odd=P(E)= $0.7$

Probability of getting sum of three prime numbers selected will be even=P(E')=1-0.7=0.3= $0.3\times 100=30$ %

By using formula P(E')=1-P(E)

The measure of the angle x = 90°

$\sf\large\underline\blue{Reason:-}$

Theorem Of Tangent:-

$\rightarrow$ A radius is obtained by joining the centre and the point of tangency. The tangent at a point on a circle is at right angles to this radius.

Energy released as a gas changes into a liquid is called what? (#9)

Zinaida [17]

Answer:

Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid. Latent heat of evaporation is the energy used to change liquid to vapor. IMPORTANT: The temperature does not change during this process, so heat added goes directly into changing the state of the substance

3x + y = 6 5x - 2y = 10

Eddi Din [679]

Answer:

x=2

y = 0

Step-by-step explanation:

3x + y = 6 -------------(i)

5x - 2y = 10 -------------(ii)

Multiply (i) by 2 ===> 6x +2y = 12

(ii) ===> 5x - 2y = 10

add ============> 11x = 22

x = 22/11

x = 2

Substitute x = 2 in (i)

3*2 + y = 6

6 + y = 6

y = 6 - 6

y = 0
