Based on past experience, a building contractor sets the probability of winning a contract at 0.10. The contract is
worth $75,000 and the cost to prepare the contract proposal
is $10000. What is the expected value of the contract
proposal?

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

●yes, this statement is absolutely apt.

hope this you

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
