Find the sum of the infinite geometric sequence:<br>8, 4, 2, 1, .......​
tatyana61 [14]

Answer:

<h3>Therefore the sum if the series is 15.98!</h3>

The common ratio is 1/2 or 0.5 . If you multiply the current term by the the common ratio the the output will be the next term.

8⋅1/2=4

4⋅1/2=2

2⋅1/2=1 etc ...

because the absolute value of r is less than 1 we can use the following formula.

a/1−r where a is the first term and r is the common ratio

In our problem

a=8 and r=0.5

Substitute

8/1−0.5=8/0.5=16

The sum of this infinite geometric series is 16.

Also, another formula you can use that is guaranteed to work every time, no matter what, is:

Sn=a(r^n−1/r−1)

All the variables work the same way as above, and "n" is the number of terms in the series. So, say you wanted to find the sum of the first 10 terms and were to substitute everything in:

S10=8(0.5^10−1/0.5−1)

S10=15.984375

Therefore the sum if the series is 15.98!

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally beli
Georgia [21]

Answer: The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, but causation cannot be determined.

Step-by-step explanation:

As we know that the correlation coefficient(r) tells about the direction and the strength of the correlation but nothing about the causation.

So, if we have only correlation coefficient(r) , then causation cannot be determined.

Given , Comparing the location of the game and the number of wins, a correlation coefficient of 0.891 is calculated.

Since , correlation coefficient is positive , it means it shows a positive coreelation.

Also, 0.891 lies between 0.7 and 1 , it means it indicates a strong correlation between the location of the game and the number of wins.

Hence, the correct summarized statement about the football team winning at home would be :

"The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, but causation cannot be determined."

A local aquarium purchased a new turtle tank for their giant turtle exhibit. What is the volume of the turtle tank?
Usimov [2.4K]

Answer:

1440 m³

1200 m³

Step-by-step explanation:

A local aquarium purchased a new turtle tank for their giant turtle exhibit.

If the dimensions of the tank are 15 m by 12 m by 8 m and the tank is of a cuboid shape and its volume is given by, V = (Length) × (Width) × (Height), then the volume of the tank will be

V = 15 × 12 × 8 = 1440 m³.

Again, if the dimensions of the tank are 15 m by 8 m by 10 m, then its volume will be

V = 15 × 8 × 10 = 1200 m³ (Answer)
