Answer:
$ 0.4
Step-by-step explanation:
if we assume head costs $ x then,
body will cost $x + 2 (2 more than head)
and tail will cost $x+1
x+x+2+x+1 = $ 4.20
or, 3x = 4.20-3
or, x= 1.20/3
therefore, x=0.4
Answer:
0.0021
Step-by-step explanation:
Given:
Probability of ordering a nonalcoholic beverage is, 
Number of samples are 
Now, the complement of event 'N' is not ordering a nonalcoholic beverage.
Therefore, 
Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.
Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:
![=[P(\overline N)]^{10}\\\\=(0.54)^{10}\\\\=0.0021](https://tex.z-dn.net/?f=%3D%5BP%28%5Coverline%20N%29%5D%5E%7B10%7D%5C%5C%5C%5C%3D%280.54%29%5E%7B10%7D%5C%5C%5C%5C%3D0.0021)

Answer:
66.66
Step-by-step explanation:
So for this one all you really have to do is turn 2/3 into a precent which is pretty easy.
This fist step to this would just be dividing 2 and 3
2/3=0.66666666666666666666 (and on and on and on)
Now just move the decimal 2 times to the right
66.6666666666666666666666
And of course round it, and in this case to the hundreth place
66.66
