Answer:

Option D. -3.9 will be the answer.

Step-by-step explanation:

Change in weight of the whale in first week = (-2.1) pounds

Change in weight of the whale in second week = (+0.3) pounds

Change in weight of the whale in 3rd week = (-1.7) pounds

Change in weight of the whale in 4th week = -0.4 pounds

Total change in weight over the period of 4 weeks = - 2.1 + 0.3 - 1.7 - 0.4

= -3.9 pounds

Therefore, Option D. -3.9 will be the answer.

Pepsi [2]

Answer:

See below

Step-by-step explanation:

Alex finally understands how Bob was trying to trick him into winning the bet because of how he puts in the condition for probability being less than 10%. Whichever way the outcome of the coin toss turns out to be, it will be in Bob's favor and Alex will lose the bet. If the coin is flipped 3 times, the probability of having heads exactly twice is \frac{4}{9}
