Acoin, having probability p of landing heads, is continually flipped until at least one head and one tail have been flipped. (a) find the expected number of flips needed. (b) find the expected number of flips that land on heads. (c) find the expected number of flips that land on tails.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
