<span>P(X > 164)
now the corresponding z is,
z = (X - μ)/σ
z = (164 - 170)/6
z = -6/6
z = -1 (table value against it will be 0.15866)
P(z > 0.15866)
= 1 - 0.15866
=P(z > 0.15866)
= 0.84134
=0.84134 * 1200
= 1009.608 ≈ 1010
hope it helps

I hope it helps u dear
Answer: x = 101.75
Step-by-step explanation:
Hi, to answer this question we have to solve the equation give, by isolating x:
8x-4 = 810
The first step is to Add 4 on both sides:
8x-4+4 = 810+4
8x = 814
Then we have to divide both sides by 8:
8x/8 = 814/8
Finally, the solution is:
x = 101.75
