Answer» ONG>ANSWER: i. 7m2n+ 22n ii. 2b^2 Step-by-step EXPLANATION: i. 16m2n + 14n - ( 9m2n - 8N ) = 16m2n + 14n - 9m2n + 8n = 16m2n - 9m2n + 14n + 8n = 7m2n + 22n ii. a^2 + b^2 - ( a^2 - b^2 ) = a^2 + b^2 - a^2 + b^2 = a^2 - a^2 + b^2 + b^2 = 2b^2

3.

Subtract (i)9m²n - 8n from 16m²n + 14n ii)a² - b² from a² + b²

Answer» ONG>ANSWER:

i. 7m2n+ 22n

ii. 2b^2

Step-by-step EXPLANATION:

i. 16m2n + 14n - ( 9m2n - 8N )

= 16m2n + 14n - 9m2n + 8n

= 16m2n - 9m2n + 14n + 8n

= 7m2n + 22n

ii. a^2 + b^2 - ( a^2 - b^2 )

= a^2 + b^2 - a^2 + b^2

= a^2 - a^2 + b^2 + b^2

A dice is thrown twice. What is the probability that

(i) 5 will not come up either time ?

(ii) 5 will come up at least once ?

$\huge\star\:\:{\orange{\underline{\red{\mathbf{Answer}}}}}$

Probability of getting 5 on throwing the dice once .

Sample SPACE $\begin{cases}(5,<klux>1</klux>)\\(5,2)\\(5,3)\\(5,4)\\(5,5)\\(5,6)\end{cases}$

For tossing it twice we have 11 outcomes

Number of outcomes we get on throwing a dice once = 18

So , hence total outcomes on throwing it twice = 18 × 2 = 36

Number of times we can get a 5 = 11

i ) Number of times we won't get a 5

$\hookrightarrow\:36\:-\:11\:=\:25$

Event 1 = Probability of not getting a 5 either time

Event 1 = $\frac{Favorable\: outcomes}{Total\: number\:of\: outcomes}$

Event 1 = $\dfrac{25}{36}$

_____________________________________

ii ) Number of times we will get 5 atleast once = 11

Event 2 = Probability of getting a 5 atleast one time

Event 2 = $\frac{Favorable\: outcomes}{Total\: number\:of\: outcomes}$

Event 2 = $\dfrac{11}{36}$

The equatiom cannot be solved in integers is 5x-8=-18 , 3y-5=y-1 , 3p+8=3+p , 9z+8= 4z-7

Answer»

ong>Step-by-step explanation:

5x = -18 +8

5x = -10

x = -10/-5

x= 10/5

x =2

3y-5 = y-1

3y-y=-1+5

2y = 4

y = 4/2

y = 2

3p + 8 = 3+p

3p -p = 3-8

2p = -5

p= -5/-2

p = 5 /2

9z+8 = 4z-5

9z- 4z = -5-8

5z = -13

z = -13/-5

z= 13 / 5
