Answer:

The solution for the given algebraic equation is $\frac{ - 2}{71}$

Step-by-step explanation:

Given algebraic equation as :

$\frac{1}{2}$ ( x - 8 ) + 1 = 2 ( 18 x - 1 )

Now solving the equation while opening the brackets

So, $\frac{1}{2}$ × x - $\frac{1}{2}$ × 8 + 1 = 2 × 18 x - 2

Or, $\frac{x}{2}$ - $\frac{8}{2}$ + 1 = 36 x - 2

or, $\frac{x}{2}$ - 4 + 1 = 36 x - 2

or, $\frac{x}{2}$ - 3 = 36 x - 2

or, $\frac{x}{2}$ - 36 x = - 2 + 3

Or, $\frac{x}{2}$ - 36 x = 1

or, $\frac{x - 72 x}{2}$ = 1

or, $\frac{- 71 x}{2}$ = 1

∴ 71 x = - 2

I.e x = $\frac{ - 2}{71}$

Hence The solution for the given algebraic equation is $\frac{ - 2}{71}$ Answer

Answer:

Step-by-step explanation:

firstly you separate y

y=-x-1

which means that the slope is equal to -1

then you flip the slope so -1 over -1 which is equal 1

J and K are independent events. P(J | K) = 0.1. Find P(J)

statuscvo [17]

$\mathbb P(J|K)=\dfrac{\mathbb P(J\cap K)}{\mathbb P(K)}=\dfrac{\mathbb P(J)\mathbb P(K)}{\mathbb P(K)}=\mathbb P(J)$

because $\mathbb P(J\cap K)=\mathbb P(J)\mathbb P(K)$ due to independence. So $\mathbb P(J)=0.1$ .
