the lateral area and total area of regular pyramid with a square base is 130
Answer:
Events E and F are independent.
Step-by-step explanation:
E = {multiple of 3} = {3, 6, 9, 12}
P(E) = 4/12
F = {even number} = {2, 4, 6, 8. 10, 12}
P(F) = 6/12
E and F = {even and multiple of 3} = {6, 12}
P(E∩F) = 2/12
In order for two events to be independent the following relationship must be true:

Testing this property:

The relationship holds true, thus events E and F are independent.
Use proportions:
height/shadow
2.6/1.24 = x/38.25
Cross multiply
1.24x=99.45
x = 80.2016129
Area of AAFD= 54centimeters squared
