Answer:
P(x < 92) is 0.16
Step-by-step explanation:
We are given that the normal distribution has a mean of 98 and a standard deviation of 6.
Mean =
Standard deviation =
We are supposed to find P(x < 92)
Formula :
Z=-1
Refer the z table for p value
So,p value = 0.1587
So, P(x < 92) is 0.16
Option A is true
Hence P(x < 92) is 0.16
Answer:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
