Answer: option A
Step-by-step explanation: We can only make a conclusion regarding this question by picking a level of significance.
Hence I will assume a 5% level of significance, that's α = 0.05.
If p > α, it simply means that we have a high chance of committing a type 1 error (because α is the probability of committing a type 1 error), hence we reject the null hypothesis meaning it is wrong.
If p < α, it means that we have a very low chance of committing a type 1 error hence we accept the null hypothesis because it is right.
Note even if we decide to try any reasonable value of α, we will come to the same conclusion made above.
48t + 265 = 553,
Subtract 265 on both sides,
48 + 265 - 265 = 553 - 265 = 288,
48t = 288,
288 divided by 48 = 6,
t = 6,
No a hexagon does not have exactly 2 obtuse angles because all the angles on a hexagon are obtuse angles
We assume the triangle is a right triangle. In a 30°-60°-90° triangle, the longest side is twice the length of the shortest.
... 4x = 2(√(x/2))
... 2x = √(x/2) . . . . . . divide by 2
... 4x² = x/2 . . . . . . . . square both sides
... 8x² - x = 0 . . . . . . . multiply by 2, subtract x
... x(8x -1) = 0 . . . . . . . factor
... x = 0 . . . or . . . x = 1/8 . . . . . . values of x that make the factors zero
The first case (x=0) is a "degenerate" case and is not useful. The entire triangle is a single point in that case.
The value of x is ...
... x = 1/8
