Normalizing the bounds,
y=186, z = (186-200)/12 = -1.17
y = 210, z = (210 - 200)/12 = 0.83
We want the area of the standard normal between those. Looking it up in the cumulative table,
Ф(1.17) = 0.87900
Ф(0.83) = 0.79673
We need Ф(-1.17) which is 1 - Ф(1.17)
Then the probability we seek is
p = Ф(0.83) - Ф(-1.17) = Ф(0.83) + Ф(1.17) - 1 = 0.87900 + 0.79673 - 1 = 0.67573
Answer: 67.6%
Because 1 centimeter is smaller than 1 inch, so more centimeters than inches can fit in a given distance.
The value of 4 in 34 258 is 4000 - four thousand.
The value of 4 on 47614 is 40 000 - forty thousand.
The first is10 times less than the second and the second is ten times more than the first:
4000*10=40000
You can also say that the first is 0.1 times the second.
It is given in the question that
You are buying a new printer and a new scanner for your computer and you cannot spend over $150. The printer you want costs $80.
Let the price of scanner be $ x .
So we have

Subtracting 80 from both sides

It means , the price should be not more then $70 .
Therefore in case, the price of scanner is $75, then you will not remain within your budget .
The answer is -4+72/2y+9 when you solve using polynomial division :)
