Heres the full question
The following is a histogram showing the distribution per year of the cumulative property damage caused by tornadoes over the period 1950 to 1999 in each of the 50 states and Puerto Rico. The data are in millions of dollars, and the class intervals are 0 to < 10, 10 to < 20, and so forth. The percent of the data with average property damage of under $20M dollars is about:
Data is in the attachment below.
Solution
The frequency below 20 is = 25+6
Total frequency = 50
The percent of the data with average property damage of under $20M dollars is about: = 31/50 = 62%

Answer:
The relative class frequency for the lowest class is 0.2.
Step-by-step explanation:
The given frequency table is
Ages Frequency
40-50 10
50-60 28
60-70 12
Total 50
It means sample size is 50.
Formula for relative frequency is
![\text{Relative frequency}=\dfrac{\text{Class frequency}}{\text{Sample size}}](https://tex.z-dn.net/?f=%5Ctext%7BRelative%20frequency%7D%3D%5Cdfrac%7B%5Ctext%7BClass%20frequency%7D%7D%7B%5Ctext%7BSample%20size%7D%7D)
We need to find the relative class frequency for the lowest class.
So, relative class frequency for class interval 40-50.
![\text{Relative frequency}=\dfrac{10}{50}=0.2](https://tex.z-dn.net/?f=%5Ctext%7BRelative%20frequency%7D%3D%5Cdfrac%7B10%7D%7B50%7D%3D0.2)
Therefore, the relative class frequency for the lowest class is 0.2.
Answer:
h = 452.5 ft
Step-by-step explanation:
Angle of elevation from P to top of the pole = 65°
Horizontal distance between the pole and point P = 21 ft
By Applying tan rule in the given triangle ABP,
tan(∠APB) = ![\frac{AB}{PB}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BPB%7D)
tan(65°) = ![\frac{h}{21}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B21%7D)
h = 21[tan(65°)]
h = 452.491
h ≈ 452.5 ft
Therefore, height of the pole is 452.5 ft.
