The answer is 7
7^ ⁴ = 49
To get Andy’s descent as a unit rate, we can express this
in terms of ratio of distance over time.
The total distance he descended is 10 feet while the
total time 2 ½ minutes or 2.5 minutes. Therefore his rate is:
rate = 10 feet / 2.5 minutes
rate = 4 feet / minute
Answer:
16
Step-by-step explanation:
Make a proportion:
66/12 = (104-r)/r
Simplify:
r = 16
Elements of sample space = 8
Elements of sample space are the possible outcomes involved in the event. In this case, there are 4 possible outcomes in pulling out one marble since there are 4 available marbles and another 2 outcomes for the tossing of coins. If it is a combined event, then multiplying the different possible outcomes of each event will give the elements of the sample space.
4 * 2 = 8
