Answer:
Step-by-step explanation:
There are 2 ways to proceed further.
Option A is with using the random number table.
- Let us assume that each gravestone has a unique number between 1 and 55914.
- Choose a row at random from the table.
- Take the first number consisting of 5 digits, if the number corresponds with a number between 1 and 55914, then select the corresponding plot, otherwise move on to the next 5 digit-number.
Repeat until 395 gravestones have been selected.
Option B is with using any calculator with capability of generating random integer. Here for example consider any TI series programmable calculator.
- Enter the following command into your calculator:
randInt(1,55914,395)
- The first and second number are the lower and upper limits between which the values have to lie.
- The third number is the number of required selections.
The first one and the second one are the correct sums
A would be your answer.
(I am going to assume that the set of numbers are multiplied by exponents.)
To solve you just need to calculate each one. Note that for positive exponents you move the decimal point to the right and negative exponents you move the decimal point to the left.

The first scientific notation would be equal to 2700 because you move the decimal point 3 places to the right, since the exponent is positive.

The second scientific notation would be equal to 0.00424 because you move the decimal point 3 places to the left, since the exponent is negative.

The third scientific notation would equal 470 because you move the decimal point 2 places to the right, since the exponent is positive.

The last scientific notation would equal 0.043 because you move the decimal point 2 places to the left, since the exponent is negative.
