Answer:
720 mi²
Step-by-step explanation:
The map has a scale of 1 in: 30 mi, meaning that for every inch you see on the map, in the real-life location, it will measure 30 miles. So we can find the area of the park on the map and then turn it into miles using the scale:
Area of a rectangle:
Replace the known values:
The area on the map is 24 mi², we can turn it to miles using the scale by multiplying our result with 30:
And last but not least, don't forget to put the unit!
Answer:
Complete Table:
Result of Roll ------ Frequency ------- Experimental Probability
1 --------------------------- 22 ------------------- 0.176
2 --------------------------- 13 ------------------- 0.104
3 --------------------------- 18 ------------------- 0.144
4 --------------------------- 29 ------------------- 0.232
5 --------------------------- 37 ------------------- 0.296
6 --------------------------- 6 ------------------- 0.048
Step-by-step explanation:
Required: Complete the table
The table is divided into 3:
1. Result of Roll
2. Frequency (F)
3. Experimental Probability (P)
The relationship between (2) and (3) is:
Where
N = Number of Rolls
N = 125
For Roll of Result = 2
Frequency = 13
The probability is calculated as thus:
For Roll of Result = 3
Probability = 0.144
The Frequency is calculated as thus:
For Roll of Result = 4
Frequency = 29
The probability is calculated as thus:
For Roll of Result = 5
Probability = 0.296
The Frequency is calculated as thus:
For Roll of Result = 6
Frequency = 6
The probability is calculated as thus:
For Roll of Result = 1.
To get the frequency; we subtract the sum of frequencies of roll of results 2 to 6 from the total number of rolls.
In other words:
Frequency of 1 = Total Rolls - (Frequency of 2 + Frequency of 3 + Frequency of 4 + Frequency of 5 + Frequency of 6)
Frequency of 1 = 125 - (13 + 18 + 29 + 37 +6)
Frequency of 1 = 125 - 103
Frequency of 1 = 22
The probability is calculated as thus:
