Answer:
It seems like the question is not complete. So, I will asume that the complete question is: " A bomb is to be dropped along a mile-long line that stretches across a practice target. The target center is at the midpoint of the line. The target will be destroyed if the bomb falls within a tenth of a mile on either side of the center. Find the Probability that the target is destroyed if the bomb falls randomly along the line."
Step-by-step explanation:
The total of possible cases is the length of the line = 1 mi ;
The favourable cases are the two lengths of 0.1 mi = 0.2 mi ;
Assuming the bomb has no bias for any point ,
the probability of favourable cases' occurrence is 0.2/1 = 0.2
Answer:
1.3905 × 10^4
Step-by-step explanation:
First you should multiply all the two numbers inside the parentheses
5.7 × 105=598.5
4.6 × 106=487.6
2.9 × 105=304.5
Now add the three numbers
598.5+487.5+304.5= 1390.5
scientific notation: Put the decimal after the first digit. To find the exponent count the number of places from the decimal to the end of the number.
the answer in scientific notation: 1.3905 × 10^4
Answer is -46+11i
