Answer:

a. Kenya's growth seems to be a large population influx, an increase in the pre-reproductive stage.

b. There is a decrease in the younger generation, meaning that the reproductive part of the population is more than the pre-reproductive part. Which means less of an incline in population.

c. You can see the differences within the countries, that the growth rate in Kenya is extremely high, the United States more moderate, while Germany is somewhat even throughout. Germany is not growing much in comparison to Kenya.

At a certain temperature the speeds of six gaseous molecules in a container are 2.0 m/s, 2.2 m/s, 2.6 m/s, 2.7 m/s, 3.3 m/s, and

Answer:

root-mean-sqaure = 2.77 m/s

average = 2.72 m/s

The root-mean-square is always the largest because it takes account of the variance of the spread of the data. The increase is related to the fact that the data varies to sample.

Explanation:

The rootmean-square (R) is the square root of the squares of the valeus divided by the number of the datas.

$R = \sqrt{\frac{x1^2 + x2^2 +...+xn^2}{n} }$

$R = \sqrt{\frac{(2.0)^2 + (2.2)^2 + (2.6)^2 + (2.7)^2 ^(3.3)^2 + (3.5)^2}{6} }$

R = √(46.03)/6

R = 2.77 m/s

The average speed is the sum of the speeds divided by the number of datas:

$A = \frac{2.0 + 2.2 + 2.6 + 2.7 + 3.3 + 3.5}{6}$

A = 16.3/6

A = 2.72 m/s

What is the pOH of a<br> 5.6 x 10-5 M solution of cesium<br> hydroxide (CsOH)?

Rudiy27

Answer: 4.25

Explanation: CsOH=Cs+

pOH= -log10

= -log10(5.6*10^-5)

= -log10(5.6*10^-5)=-(-4.25)

=4.25
