Answer:

for \: independent \: events :  \\ P(AUB) = P(A) + P(B) \\ P(AUB) =  \frac{2}{3}  +  \frac{1}{5}  \\  =  \frac{13}{15}

Step-by-step explanation:

P(AUB) is P(A) + P(B) because P(AnB) is zero.

P(AUB) = P(A) + P(B) - P(A{ \huge{n} }B) \\ P(AUB) = P(A) + P(B) + 0

Musya8 [376]

Answer: 400 Shoppers

Step-by-step explanation:

Given

156 people spent the night in Wal-mart

These 156 people represent 39% of total shoppers at Wal-mart

Suppose x is the total no of shoppers at Wal-mart

So, we can write

\Rightarrow 39\%\ \text{of}\ x=156\\\Rightarrow 0.39\times x=156\\\\\Rightarrow x=\dfrac{156}{0.39}=400\ \text{People}

farmer joe is enclosing a rectangular area on his arm for his chicken with 200 feet of fencing that he recently acquired in a tr
Llana [10]
For this case, the area is given by:
 A = x * (200-2x)
 Rewriting:
 A = 200x-2x ^ 2
 Deriving the expression we have:
 A '= 200-4x
 Equaling zero we have:
 200-4x = 0
 We clear x:
 4x = 200
 x = 200/4
 x = 50 feet
 Then, the maximum area is:
 A (50) = 50 * (200-2 * 50)
 A (50) = 5000 feet ^ 2
 Answer:
 
the maximum possible area that can be enclosed with his 200ft of fencing is:
 A
 (50) = 5000 feet ^ 2
