The answer is actually 1.571
Answer:
Hence the probability that she paid cash is 0.105
Step-by-step explanation:
P(cash) = 0.3
P(credit card ) = 0.3
P(debit card ) = 0.4
P ( more than $50 | cash ) = 0.2
P (more than $50 | credit card ) =0.9
P (more than $ 50 |debit card ) = 0.6
P ( more than $50) = P ( more than $50 | cash )* P (cash) + P (more than $50 credit card ) * P(credit card ) + P (more than $ 50 |debit card )* P(debit card )
= 0.2 * 0.3 + 0.9 * 0.3 + 0.6* 0.4
= 0.57
P ( more than $50) = P ( more than $50 | cash )* P (cash) / P ( more than $50)
= 0.2* 0.3 / 0.57
= 0.105

Answer:
22.8
Step-by-step explanation:
the rectangular has :
the length CD =√[(3+3)²+(0-5)²]
= √(36+25) = √61 = 7.8
the width BC =√[(5-3)²+(3-0)²]
=√(4+9 =√13 = 3.6
so, the perimeter = 2(7.8 + 3.6)
= 2× 11.4 = 22.8
