Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
Answer:
I would say NO
Step-by-step explanation:
because if you look at those triangles, the one on they have two matching angles and two one side. The other angle in the triangle on the left isn't marked or anything so we can assume and the one on the right has no marked side. I hope I made a little sense. I don't know how to explain but I guess in short you could say that you don't have enough information to determine if they're the same
AGAIN!! I CAN'T PROMISE IF THIS IS RIGHT!!
