What is the next term in the sequence below? -324,108,-36,12,...
liq [111]
This is a geometric sequence with a common ratio of -1/3 and an initial term of -324.  Any geometric sequence can be expressed as:
a(n)=ar^(n-1), in this case a=-324 and r=-1/3 so
a(n)=-324(-1/3)^(n-1)  so the 5th term will be
a(5)=-324(-1/3)^4
a(5)=-324/81
a(5)= -4

Viktor [21]

Answer:

Sample mean for solution 1:  19.27; sample mean for solution 2:  10.32

Step-by-step explanation:

To find the sample mean, find the sum of the data values and divide by the sample size.

For solution 1, the sum is given by:

9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7

The sample size is 10; this gives us

192.7/10 = 19.27

For solution 2, the sum is given by:

10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2

The sample size is 10, this gives us

103.2/10 = 10.32

Sydney has a rectangular pool as shown in the figure. The pool is 6 feet deep throughout. mc017-1.jpg How much water is needed t
densk [106]
The amount of water that is needed to fill the pool is equal to the volume of the pool.

The pool is rectangular, with uniform depth so the volume of pool will be the product of its length , width and depth.

Thus,

Volume = 25 x 18 x 6 = 2700 ft³ 

This means, 2700 ft³ water is needed to fill the pool.
