Answer:
9.5
Step-by-step explanation:
There is no changeover in the first throw. The probability of each changeover is 1/2 and it doesnt depend on the other changeovers. The only thing that modifies each experiment is the result of the previous flip, but regardless of weather it was tails or heads, the probability will always be 1/2.
Since the coin is flipped 20 times and the first time there is no changeover, there are a total of 19 experiments. All of them independent and with probability 1/2. Therefore, the total amount of changeovers for 20 flips is a random variable with distribution Binomial B(19,0.5), the expected value of a Binomial B(n,p) is n*p. In this case, the expected value of changeovers for n=20 is 19*0.5 = 9.5.

"<span>2/3 of the baked chicken was left over. Michela ate 1/4 of the leftover chicken. How much of the whole chicken did Michela eat?"...
This can solved by multiplying the fraction by each other:
2/3*1/4
2*1=2
3*4=12
=2/12 or 1/6.
She 1/6 of the whole chicken.
Hope this helps.

Answer: 113.1 cm^2
Step-by-step explanation: The formula to find the area of a circle is 3.14r^2. R stands for radius which is 6 in this case so just plug that in for R. 3.14(6)^2=113.1
