There is one zero in the ten thousands place.
There is another zero in the hundreds place.
Both of them have the value of zero.
Answer:

Step-by-step explanation:

The probability that two of the coins will be tails is 1/2
It is 1/2 because "at least two tails" means that two tails and the rest of the number of tails, which is 3. In total the three coins have 6 sides. The chance of having two tails and one is three out of 6, simplified is 1/2 ;)
(d km)/(195 nm) = (185 km)/(100 nm)
d = 1.95*185 km ≈ 361 km
195 nautical miles is about 361 kilometers.
Recall that i represents the square root of -1, so by squaring it we get -1.
(2 + 4i)(7 - 3i)
= 14 - 6i + 28i + 12
= 26 + 22i
