Answer:
Eight thousand fourteen hundred twelve and seven
Simplify
4ax+12-3ax=25+3a
ax+12=25+3a
ax-3a=25-12
a(x-3)=13

Answer:
2046
Step-by-step explanation:
The sum of 2^0 to 2^x added is equal to 2^(x+1)-1 but because 2^0 isnt included its 2^11-2 or 2048-2
Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation
Random variable, x = 100
To test P(x < 100), calculate the z-score.
z = (x-μ)/σ = (100 - 89)/23 = 0.4783
From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%
Answer: 68.4%
