Alex and Fatima both randomly guess all of the answers on a four-question true/false quiz. Because their guesses are random, each question has an equal chance of being correct or incorrect. After the quiz, they try to
predict their grades.

Alex thinks that the probability of getting correct answers on the first three questions is equal to the probability
of getting exactly three questions correct overall. Fatima disagrees. She thinks that the probability of getting
three questions correct overall is greater.

The sample space of possible outcomes is listed below. C represents a correct answer, and I represents an
incorrect answer.
Who is correct. Alex or Fatima?

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

b. ol

step-by-step explanation:

i got the answer right on edg.

congruent: (geometry) (of figures) identical in form; coinciding exactly when superimposed.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
