Answer: The theoretical probability of the coin landing heads up is 0.7
Step-by-step explanation:
Hi, to answer this question we simply have to divide the number of times that the coin lands heads up (42 times) by the number of times that the coin was flipped:
Mathematically speaking:
42 /60 = 0.7 (decimal form)
The theoretical probability of the coin landing heads up is 0.7
For the or percentage form we simply multiply the result by 100:
0.7 (100) = 70%

Answer:
it dilated by two
Step-by-step explanation:
N^2.....because this is the product of n and itself, not the sum
If it is divisible by 3 and 7 then it is divisible by (3 times 7)
3 time s7=21
just do muliplyes of 21 and find which are between 364 and 384
21
42
63
...
336
357
378
399
answer is 378
