Answer:
d. 11.6
Step-by-step explanation:
The results of the first die and the second one are independent to each other. The expected value of Z is obtained, therefore, by summing the expected values of both X and Y, because Z = X+Y and X and Y are independent. As a result
You can round 46 to 50, not 500
Equation:
Time*speed= distance
1.7(time)*22.4(speed)=38.08meter(distance)
A number that's bigger than 4.3 is the answer :)
