The top speed of a wildebeest is 64 km/h and the top speed of a zebra is 64.4 km/h. How much faster is a zebra in feet per secon
7nadin3 [17]
The first thing we must do is subtract both speeds.
 We have then:
 64.4 km / h - 64.0 km / h = 0.40 km / h
 We now change units taking into account the following conversions:
 1h = 3600s
 1km = 3280.84 feets
 We have then:
 0.40 * (3280.84 / 3600) = 0.364537778 feet / s
 Answer: 
 a zebra is faster 0.364537778 in feet per second

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
