Answer:
x = 3/8
Step-by-step explanation:
The difference of the two squares can be found several ways. One way uses the "difference of squares" special form.
a² -b² = (a -b)(a +b)
For the given squares, this is ...
(2x +3)² -(2x -3)² = ((2x +3)-(2x -3))((2x +3) +(2x -3)) = 6(4x) = 24x
We want to find x that makes this difference be 9:
24x = 9
x = 9/24 = 3/8
For the value x = 3/8, the difference between the squares of the binomials will be 9.
2.1 + (–3.4 + 5) = [ + (–3.4)] + 5 = false
2.1 + (–3.4 + 5) = 3.7
[ + (–3.4)] + 5 = 1.4
Thus your answer is 2.1
Answer:
Type I error
Step-by-step explanation:
A type I error is a false positive, which is when a researcher rejects a null hypothesis when it is, in fact, true
A type II error is a false negative, which is when a researcher fails to reject a null hypothesis and accepts it when it is, in fact, false.
