Using a six-sided die, you have rolled a 6 on each of four successive tosses. What is the probability of rolling a 6 on the next
ollegr [7]

Answer:

The probability of rolling a 6 on the next toss = 1/6

Step-by-step explanation:

Given - Using a six-sided die, you have rolled a 6 on each of four successive tosses.

To find - What is the probability of rolling a 6 on the next toss?

Proof -

As the outcomes of previous rolls do not affect the outcomes of future rolls.

And there is one desired outcome and six possible outcomes.

So,

The probability of rolling a six on the fifth roll = 1/6 which is same as the probability of rolling a six on any given individual roll.

So,

The answer is -

The probability of rolling a 6 on the next toss = 1/6

The line passing the points (-4,5) and (x,-13) is parallel to a line that has a slope of 9/2 what is the value of x ?
Sergeeva-Olga [200]

Answer:

x = - 8

Step-by-step explanation:

Calculate m using the slope formula and equate, since parallel lines have equal slopes.

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 5) and (x₂, y₂ ) = (x, - 13)

m = \frac{-13-5}{x+4} = \frac{-18}{x+4} and equating

\frac{-18}{x+4} = \frac{9}{2} ( cross- multiply )

9(x + 4) = - 36 ( divide both sides by 9 )

x + 4 = - 4 ( subtract 4 from both sides )

x = - 8
