Construct a frequency polygon that represents the following data regarding the selling prices of houses sold in 2006 for a particular neighborhood. prices of houses class frequency 176016–206015 6 206016–236015 8 236016–266015 6 266016–296015 5 296016–326015 4 step 1 of 5 :

step 1 . find the midpoint for the second class.

step 2. find the midpoint for the fourth class.

step 3. find the value that should be written at the location indicated by the [? ] on the vertical axis of the graph.



step 4. find the value that should be written at the location indicated by the [? ] on the horizontal axis of the graph.



step 5. plot the data values for each of the classes in the frequency polygon.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
