Answer:
D. 48
Step-by-step explanation:
Let's first find the probability that in the first 40 trials, exactly two of the coins are heads.
We know that there were 16 such outcomes of 2 heads and 1 tail, and there was a total of 40 possible outcomes. So our probability is:
16 / 40 = 4 / 10 = 2/5
We can assume that the probability that in the next 120 trials, about 2/5 of the outcomes will also be 2 heads and 1 tail. So, we multiply 2/5 by 120 to figure out that exact number:
(2/5) * 120 = 240/5 = 48
The answer is thus D.
Answer:
x=25, 120
Step-by-step explanation:
The two angles form a straight line so they add to 180
60 + 4x +20 =180
Combine like terms
4x+80 = 180
Subtract 80 from each side
4x+80-80 =180-80
4x= 100
Divide by 4
4x/4 =100/4
x= 25
The exterior angle is
4x+20 = 4*25+20 =100+20 =120
Answer: C
Explanation: They are the same exact shapes, the one on the right is slightly rotated and scaled smaller but other than that they are the most similar
