Suppose that E and F are two events and that Upper P (Upper E and Upper F )equals0.3 and Upper P (Upper E )equals0.5. What is Up
m_a_m_a [10]

Answer:

P(\frac{F}{E}) =\frac{0.3}{0.5} =0.6

Step-by-step explanation:

<u>Step 1</u>:-

Suppose that E and F are two events and that P(E n F) = 0.3

also given P(E) =0.5

<u>Conditional probability</u>:-

if E₁ and E₂ are two events in a Sample S and P(E₁)≠ 0, then the probability of E₂ , after the event E₁ has occurred, is called the <u>Conditional probability</u>

of the event E₂ given  E₁ and is denoted by

P(\frac{F}{E}) = \frac{P(EnF)}{P(E)}

P(\frac{F}{E}) =\frac{0.3}{0.5} =0.6

Write an equation that has one solution, an equation that has no solution and an equation that has infinite many solutions. Each
ValentinkaMS [17]

Answer:

  • 3x + 4 = 9x -6
  • 3x + 4 = 3x + 5
  • 9x + 6 = 9x + 6

Step-by-step explanation:

Let x is the variable in each type of equation

1/ an equation that has one solution:

3x + 4 = 9x -6

<=> 9x - 3x = 4+6

<=> 6x = 10

<=> x = \frac{10}{6}

2/ an equation that has no solution:

3x + 4 = 3x + 5

<=> 3x - 3x = 5-4

<=> 0 = 1 impossible

3/ an equation that has infinite many solutions:

9x + 6 = 9x + 6

<=> 9x - 9x = 6 -6

<=> 0 = 0 (obvious)  no matter what we put in for  x

Hope it will find you well.

What is the value of n?
qwelly [4]

Answer:

n = 18

Step-by-step explanation:

Hi there!

\displaystyle\frac{n}{30}=\frac{60}{100}

Isolate <em>n</em> by multiplying both sides by 30:

\displaystyle\frac{n}{30}*30=\frac{60}{100}*30\\\\n=\frac{1800}{100}

Simplify the fraction:

\displaystyle n=\frac{18}{1}\\\\n=18

I hope this helps!
