The graphs below are based on government data on unemployment for 2017.
lord [1]

You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.

The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.

We can deduce that, if x is the number of people between 16 and 19, we have

\dfrac{14}{100}x=700 \iff \dfrac{7}{50}x=700 \iff \dfrac{x}{50}=100 \iff x=5000

So, by the relation between the two graphs, we can deduce the total population for each age group.

Urgent Help needed w/ right triangle trig
Svetllana [295]
It is clearly understood from the image that LPNM is a square.

Let the side of the square be 'a' units.

Then by Pythagorean theorem.

{c}^{2}  =  {a}^{2}  +  {a}^{2}  \\  \\  {c}^{2}  = 2 {a}^{2}
Now taking square root on both side we get ;

c =  \sqrt{2} a
Now pluging the value of C in the above equation we get ;

12 =  \sqrt{2} a \\  \\ a =  \frac{12}{ \sqrt{2} }  = 6 \sqrt{2}
Therefore LP = 6√2 units.
