Answer:

The Probability that the spinner landed on the colors blue and green in any order = 2/9

Step-by-step explanation:

Given - Azul spun a tri-color spinner twice.

To find - What is the probability that the spinner landed on the colors blue and green in any order?

Solution -

Given that,

A tri-color spinner spun twice

So,

The Sample Space, S = {BB, BG, BY, GB, GG, GY, YB, YG, YY}

⇒n(S) = 9

Now,

Let A be an event that the spinner landed on the colors blue and green

So,

A = {BG, GB}

⇒n(A) = 2

Now,

Probability that the spinner landed on the colors blue and green in any order = n(A) ÷ n(S)

         = 2 ÷ 9

∴ we get

The Probability that the spinner landed on the colors blue and green in any order = 2/9

Dafna11 [192]

Answer:

<em>There is no significant difference in the amount of rain produced when seeding the clouds.</em>

Step-by-step explanation:

Assuming that the amount of rain delivered by thunderheads follows a distribution close to a normal one, we can formulate a hypothesis z-test:

<u>Null Hypothesis </u>

\bf H_0: Average of the amount of rain delivered by thunderheads without seeding the clouds = 300 acrefeet.

<u>Alternative Hypothesis </u>

\bf H_a: Average of the amount of rain delivered by thunderheads by seeding the clouds > 300 acrefeet.

This is a right-tailed test.

Our z-statistic is  

\bf z=\frac{370.4-300}{300.1/\sqrt{30}}=1.2845

We now compare this value with the z-critical for a 0.05 significance level. This is a value \bf z^* such that the area under the Normal curve to the left of \bf z^* is less than or equal to 0.05

We can find this value with tables, calculators or spreadsheets.

<em>In Excel or OpenOffice Calc use the function </em>

<em>NORMSINV(0.95) </em>

an we obtain a value of  

\bf z^* = 1.645

Since 1.2845 is not greater than 1.645 we cannot reject the null, so the conclusion that can be drawn when the significance level is 0.05 is that there is no significant difference in the amount of rain produced when seeding the clouds.

3+x) 5<br> Solve it for me, and tell me how to do it EXPLANATION NEEDED
grigory [225]
I’m not too sure of what the equation is but I made a guess let me know if this was the right equation please I can redo it.

But, when solving this equation you are trying to find the value of x. To do that you have to get rid of the 3.

You would either add or subtract the 3 on both sides.

When the three is gone you should have somthing like

x = 5
- 3

Which you would move on to subtract the 5-3 and get 2.

x= 2

Here’s a picture of how I solved it
