Answer: all the zeroes of the above equation will be
(x-4)(x+4)(x-2)(x+2)
Step-by-step explanation:
Since we have given that
We need to find the zeroes of the above equation.
So, we will use "Split the middle terms" :
So, all the zeroes of the above equation will be
(x-4)(x+4)(x-2)(x+2)
Answer:
2.28%
Step-by-step explanation:
Let X be the number of books borrowed from a library each week
Given that X is normal with mean = 190 and std dev = 30
Thus Z score would be
Z=
Required probability or chance = P(X>250)
=P(
=P(Z>2)
=0.5-0.4772
=0.0228
=2.28%
