Answer: The value of P(E∪F) = 0.64.
Step-by-step explanation:
Since we have given that
P(E) = 0.38
P(F) = 0.38
P(E∩F) = 0.12
So, we need to find the P(E∪F).
As we know the formula for the sets.
Hence,the value of P(E∪F) = 0.64.
Answer:
Step-by-step explanation:
EC = 12÷2 = 6
ED = √(CD² - EC²) = √(16² - 6²) = √220 = 2√55 ≅ 14.8 units
Answer: 349 square units
============================================
Work Shown:
- L = 5.5 = length
- W = 5 = width
- H = 14 = height
SA = surface area of rectangular prism
SA = 2*(L*W + L*H + W*H)
SA = 2*(5.5*5 + 5.5*14 + 5*14)
SA = 2*(27.5 + 77 + 70)
SA = 2*(174.5)
SA = 349
The surface area is 349 square units.
Answer:
a.15
Step-by-step explanation:
11=6+k/3
subtract 6
11-6=k/3
5=k/3
multiply by 3/1 (basically just opposite of 1/3)
15=k

Answer:
22.2
Step-by-step explanation:
The missing side is x
- cos19° = 21/x switch x and cos19°
- x = 21/cos 19°
x = 22.21≈ 22.2
