Answer: The answer is False.

Step-by-step explanation: In an arithmetic series with first term $a$ and common difference $d$ , the n-th term is given by

$a+(n-1)d.$

The given sequence is - 3, 9, 27, 81, 243, ...

Here, $a=3$ we cannot find the value of $d$ , since 9-3≠243-81.

So, the given sequence is not an arithmetic sequence. Furthermore, it is an infinite geometric sequence with first term 3 and common ration also 3.

Thus, the answer is False.

Please help me out! I keep getting the wrong answer

Tamiku [17]

The total amount of people who ordered a large is 5 + 12 + 8 = 25 people.

The amount of customers who bought a large cold drink is 5.

The probability that someone bought a large cold drink is 5 out of 25 people.

This is 5/25 which is 1/5 which is .2

Convert the decimal to a fraction by multiplying by 100 and adding a percent sign at the end.

.2 x 100 = 20%

Edit:

The probability was supposed to be if the customer ordered a cold drink based on people who ordered large.

The amount of people who ordered a large drink is 22 + 5 = 27.

The amount of people who ordered a cold large is 5.

To find the percent, divide the people who ordered cold large by the total people who ordered large.

This would be 5/27 which in decimal form is .185185

To convert to a percent, multiply by 100 and add a percent sign after it.

.185185 x 100 = 18.5185%

The question says to round to the nearest percent so your answer is:

19%

There are 92,746 seats available for fans at UGA's Sanford Stadium. Auburn University's Jordan-Hare Stadium has seating for 87,4

Anvisha [2.4K]

Given :

Number of seats at UGA's Sanford Stadium, $n_1 = 92,746$ .

Number of seats at Auburn University's Jordan-Hare Stadium, $n_2=87,451$ .

To Find :

How many more seats are there at UGA's stadium.

Solution :

Extra seats at UGA's stadium = seats at UGA's Sanford Stadium - seats at

Auburn University's Jordan-Hare Stadium

= 92,746 - 87,451

= 5295

Hence, this is the required solution.
