Mr. Mole left his burrow that lies 7 meters below the ground and started digging his way deeper into the ground, descending at a constant rate. After 6 minutes, he was 16 meters below the ground.

A(t)=-1.5t-7

Step-by-step explanation:

It is given that Mr. Mole left his burrow that lies 7 meters below the ground and after 6 minutes, he was 16 meters below the ground.

It means the line passing thought the points (0,-7) and (6,-16). It means the initial value is -7.

He started digging his way deeper into the ground, descending at a constant rate. The rate of change is

The rate of change is -1.5.

A(t) denote Mr. Mole's altitude relative to the ground A (measured in meters) as a function of time t (measured in minutes).

Therefore the function's formula is , here negative sign shows the Mr. Mole's altitude relative to below the ground A

d

step-by-step explanation:

d

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
