A weather forecast states that there is a 20% probability of rain in the next three days. Describe a simulation you could perfor

Answer:

my hands hurt, pls give brainilist and hope this helps

Step-by-step explanation:

Before leaving for work, Victor checks the weather report in order to decide whether to carry an umbrella. The forecast is “rain" with probability 20% and “no rain" with probability 80%. If the forecast is “rain", the probability of actually having rain on that day is 80%. On the other hand, if the forecast is “no rain", the probability of actually raining is 10%.

1. One day, Victor missed the forecast and it rained. What is the probability that the forecast was “rain"?

2. Victor misses the morning forecast with probability 0.2 on any day in the year. If he misses the forecast, Victor will flip a fair coin to decide whether to carry an umbrella. (We assume that the result of the coin flip is independent from the forecast and the weather.) On any day he sees the forecast, if it says “rain" he will always carry an umbrella, and if it says “no rain" he will not carry an umbrella. Let U be the event that “Victor is carrying an umbrella", and let N be the event that the forecast is “no rain". Are events U and N independent?

3. Victor is carrying an umbrella and it is not raining. What is the probability that he saw the forecast?

6x+9/x-5 x is not equal to 5 find inverse

algol [13]

You have f(x)=(6x+9)/(x-5) and want to find the inverse function? Please note that the parentheses are obligatory here.

1. Replace "f(x)" with y: y = (6x+9)/(x-5)

2. Interchange the variables x and y: x = (6y+9)/(y-5)

3. Solve this result for y: x(y-5) = (6y+9), or xy-5x = 6y+9. Then:

xy-6y = 9 + 5x, or y(x-6) = 9+5x
9+5x
Then y = --------------
x-6

Here x may not = 6, because division by zero would occur otherwise.

Determine the equation of the line, in point-slope form, that will get your spacecraft from Point A (0,3) to Point B (-3,0)

jeka94

$m= \frac{y2-y1}{x2-x1}$

$m= \frac{0-3}{-3-0}$

$m= \frac{-3}{-3}$

$m=1$

Point Slope Form: $(y-y1)=m(x-x1)$

$(y-3)=1(x-0)$

$(y-3)=(x-0)$

$(y-3)=(x)$

3х + 9 = 2х + 5 is it no solutions, all real numbers, or does x equal something?

zepelin [54]

Answer:

Step-by-step explanation:

<h3>Given Equation:</h3>

3x + 9 = 2x + 5

<h3>Question:</h3>

Whether x has one solution or infinite solutions or no solutions?

<h3>Solution:</h3>

=> 3x + 9 = 2x + 5

(On shifting like terms to one side we get)

=> 3x - 2x = 5 - 9

(On subtracting)

=> x = - 4

<h3>Result:</h3>

Hence, x has only one solution that is, x = -4 (Ans)
