Does anyone know the answer to the question

Step-by-step explanation:

Not specifically. That is I don't know what letter the answer is because we can't see all the choices. But I can tell you which one to pick.

Pick the one that looks like the graph below. Do it by where the graph goes up (in quadrant 1) and the y intercept which is 2. Make sure you understand where the 2 came from.

2^x = 2^0 which is 1.

The graph has a y intercept of 2 because the original question is 2*2^x

When x = 0, the intercept = 2*1 = 2

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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
