Answer:

6.  300/4 feet per hour or feet/hour

7. 90/10 feet per second or feet/sec

Try simplifying the fractions though.  

Step-by-step explanation:

average rate of change just means the change in distance per the change in time (per meaning divided by).  what is the change in distance?  700-400 = 300.  change in time is 6-2 = 4 hours. so 300/4  

Same thing, change in distance is 100 - 10 feet and change in time is 40-30 seconds so the average rate of change is 90/10 feet per second

Mickey tosses a coin 50 times and records 27 heads. Based on these results, what is the probability if
JulijaS [17]

The probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.

<h3>What is probability of an event?</h3>

It is the ratio in an event of the number of favorable outcome to the total number of outcome of that event.

As the probability of an event can not be more than the number 1. Thus, he probability of failure of a event is equal to the difference of the 1 to the success of the event.

Mickey tosses a coin 50 times and records 27 heads. Thus, the probability of getting a head is,

P=\dfrac{27}{50}\\

The probability of not getting a head or getting a tail is,

P^{-1}=1-\dfrac{27}{50}\\P^{-1}=\dfrac{50-27}{50}\\P^{-1}=\dfrac{23}{50}

Now, Mickey tosses the same coin three more times. The probability of getting three tails in these tosses are,

P_{3t}=\dfrac{23}{50}\times\dfrac{23}{50}\times\dfrac{23}{50}\\P_{3t}=\dfrac{12167}{125000}

Thus, the probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.
