Solve the equation. Check your solution. (1/2 is a fraction for one half s-1/2=1/2

Alchen [17]

Answer:

$s = 1$

Step-by-step explanation:

Given

$s - \frac{1}{2} = \frac{1}{2}$

Required

Solve for s

$s - \frac{1}{2} = \frac{1}{2}$

Add $\frac{1}{2}$ to both sides

$s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}$

Take LCM

$s + \frac{-1+1}{2} = \frac{1+1}{2}$

$s + \frac{0}{2} = \frac{2}{2}$

$s +0 = 1$

$s = 1$

There are black, blue, and white marbles in a bag. The probability of choosing a black marble is 0.36. The probability of choosi

Gala2k [10]

Answer: c) 0.75

Step-by-step explanation:

Given : The probability of choosing a black marble is P(Black)= 0.36.

The probability of choosing a black and then a white marble is P( Black and white) = 0.27.

Then by conditional probability ,

The probability of the second marble being white if the first marble chosen is black = $P(\text{white }|\text{Black})=\dfrac{\text{P( Black and white)}}{\text{P(Black}}$

$=\dfrac{0.27}{0.36}=\dfrac{27}{36}=0.75$

Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75
