20y-10x=5 in slope intercept form can you explain the steps
Studentka2010 [4]

Given:

The equation is

20y-10x+5

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

y=mx+b

Where, m is slope and b is the y-intercept.

We have,

20y-10x=5

We need to isolate y. Add 10x on both sides.

20y-10x+10x=5+10x

20y=5+10x

Divide both sides by 20.

\dfrac{20y}{20}=\dfrac{5+10x}{20}

y=\dfrac{5}{20}+\dfrac{10x}{20}

y=\dfrac{1}{4}+\dfrac{x}{2}

y=\dfrac{1}{2}x+\dfrac{1}{4}

Therefore, the slope intercept form of the given equation is y=\dfrac{1}{2}x+\dfrac{1}{4}.

The probability that a randomly selected elementary or secondary school teacher from a city is a female is , holds a second job
julsineya [31]

Answer:

The probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.90.

Step-by-step explanation:

Denote the events as follows:

<em>X</em> = an elementary or secondary school teacher from a city is a female

<em>Y</em> = an elementary or secondary school teacher holds a second job

The information provided is:

P (X) = 0.66

P (Y) = 0.46

P (X ∩ Y) = 0.22

The addition rule of probability is:

P(A\cup B)=P(A)+P(B)-P(A\cap B)

Use this formula to compute the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job as follows:

P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)\\=0.46+0.66-0.22\\=0.90

Thus, the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.90.
