It is irrational, because irrational numbers are ones that keep repeating at decimals and if you concert 43/99 to a decimal, it becomes 0.434343 and repeats on forever hope this helps you :)
Answer:
below
Step-by-step explanation:
-3x² + 6x + 6 = 0
x = (-b±√(b²-4ac))/2a
x = (-6±√(36 - 4(-3)(6)))/2(-3)
x = (-6±√108)/-6
x = 1 ± √3
The negative solution is not reasonable for he threw it forwards
1 The solution involves four steps.
Make sure the sample size is big enough to model differences with a normal population. ...
Find the mean of the difference in sample proportions: E(p1 - p2) = P1 - P2 = 0.52 - 0.47 = 0.05.
Find the standard deviation of the difference. ...
Find the probability.
From the problem, we have :
Using distributive property, multiply 3 to the expression inside the parenthesis.
This will be :
The answer is 27x - 3
1 or 3? I don’t really know
