Answer:90cents

Cost of a  10 minute call before 10pm:

37 cents + 9cents*7minutes = 37 cents+63 cents =100 cents

10% of 100cents:

100*10/100= 10 cents

Cost of  the call after 10 pm (i.e with a 10% discount)

100-10= 90 cents

Answer:

  $0.90

Step-by-step explanation:

A 10-minute call exceeds the 3-minute initial period by 7 minutes. The initial period charge is 37¢. The additional minute charge is 7·9¢ = 63¢. Then the regular charge for that call is ...

  37¢ +63¢ = 100¢ = $1.00

The 10% discount reduces the charge by ...

  10% × $1.00 = $0.10

so the final cost of the 10-minute call is ...

  $1.00 -0.10 = $0.90 . . . . . cost of the call

wariber [46]

Answer:

a. 0.76

b. 0.23

c. 0.5

d. p(B/A) is the probability that given that a student has a visa card, they also have a master card

p(A/B) is the probability that given a student has a master card, they also have a visa card

e. 0.35

f. 0.31

Step-by-step explanation:

a. p(AUBUC)= P(A)+P(B)+P(C)-P(AnB)-P(AnC)-P(BnC)+P(AnBnC)

                    =0.6+0.4+0.2-0.3-0.11-0.1+0.07= 0.76

b. P(AnBnC')= P(AnB)-P(AnBnC)

                    =0.3-0.07= 0.23

c. P(B/A)= P(AnB)/P(A)

             =0.3/O.6= 0.5

e. P((AnB)/C))= P((AnB)nC)/P(C)

                     =P(AnBnC)/P(C)

                     =0.07/0.2= 0.35

f. P((AUB)/C)= P((AUB)nC)/P(C)

                    =(P(AnC) U P(BnC))/P(C)

                     =(0.11+0.1)/0.2

                     =0.21/0.2 = 0.31
