Suppose you are writing a report on the population of the united states. in the report, you want to show the percentage of each state's population that was between the ages of 18 and 25 in 2010. which visual aid would most clearly support your purpose?

a. map
b. line graph
c. pie graph
d. bar graph

The answer is:

D. Bar graph

In a bar graph you can put in the Y axis the percentage from 0 to 100 and you just put the states in the X axis, this way you can make a visual representation of the differences on the populations ages in the different states of the United States.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
