Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒  (1-\frac{1}{4})^5

⇒  (1-0.25)^5

⇒  (0.75)^5

On solving the power, we get

⇒  (0.237304)

Now on multiplying the above value in 100, we get

⇒  23.73%

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.

What is the 101st term in the sequence 997, 989, 981, ...?
melamori03 [73]

Answer: first option.

Step-by-step explanation:

Find the common difference d of the arithmetic sequence:

d=a_n-a_{(n-1)}\\d=989-997\\d=-8

Then the formula for the 101st term is the shown below:

a_n=a_1+(n-1)d

Where:

a_1=997\\d=-8\\n=101

Substitute values into the formula. Therefore, you obtain:

a_n=997+(101-1)(-8)=197

<em>Greetings from Brasil...</em>

Here is the problem:

[(15X - 8)/3] + [(9X - 3)/2]

<em>Let's multiply everything by 6</em>

[6.(15X - 8)/3] + [6.(9X - 3)/2]

[2.(15X - 8)] + [3.(9X - 3)]

30X - 16 + 27X - 9
