97. The great wall is more than 20 000 kilometers long. And about ¾ of it is considered as properly preserved.
I guess you are asking about the value of ¾ which is properly preserved in the said length of the great wall.
=> ¾ = 0.75
Thus, the formula would be like this:
=> 20 000 * .75 = 15 000
Thus, the ¾ value of great wall that is preserved is equals to 15 000 kilometers long,
Yes this is correct answer
Answer:
A. Yes, because each of the two outcomes are equally likely.
Step-by-step explanation:
A sales representative for a baby food company wants to survey 300 random couples who are new parents to find out if their newborn child is a boy or a girl.
The representative uses a 1 for a girl and a 2 for a boy when running a simulation.
Yes, the simulation will be a fair representation of possible survey results.
A. Yes, because each of the two outcomes are equally likely.

Answer: the fraction -8/117</h3>
----------------
First, convert to an improper fraction
3 & 1/4 = 3 + (1/4)
3 & 1/4 = (12/4) + (1/4)
3 & 1/4 = 13/4
The mixed number 3&1/4 turns into the improper fraction 13/4
---------------
-2/9 divided by (3&1/4) = -2/9 divided by 13/4
To divide two fractions, you flip the second one and then you multiply
"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens
Then you multiply straight across. The numerators stick together. The denominators stick together.
numerators: -2*4 = -8
denominators: 9*13 = 117
We end up with the fraction -8/117
This cannot be reduced as there are no common factors (other than 1) between 8 and 117.
