Answer: A) a number is negative
Step-by-step explanation:
A conditional statement is written as:
If P, then Q.
Where P is the hypothesis and Q the conclusion.
In this case, we have:
If a number is negative, then the number is less than zero.
then we have:
P = a number is negative.
Q = the number is less than zero.
Then the hypothesis will be "a number is negative"
The correct option is A.

Answer:
34 grams
Step-by-step explanation:
If the remaining sample has 30.26 grams of radioactive substance, and 11% of it decayed, that means that 30.26 grams is 89% of the original. Let the original be x.
30.26=0.89x
Multiply both by one hundred
3026=89x
Divide both by 89
34=x
x=original, so the original was 34 grams.
The correct answer should be -1 and 2/3, or 4/6
We have one value, 5/6
if we subtract 1/6 from that, we get 4/6
Since we don't have a full number value, subtracting 1 from that gives us -1 and 4/6
