12 minus three is 9. 9 divided by 3 is 3. so X is three
The maximum air pressure is 43 pounds per square inch and the minimum air pressure is 41 pounds per square inch
The minimum air pressure is the least amount of air pressure that must be in the tire. The maximum air pressure is the greatest amount of air pressure that must be in the tire.
In order to determine the minimum air pressure, I would subtract the range of air pressure that can be allowed in the tire from the recommended pressure.
recommended pressure - range of air pressure
41 - 2 = 39 pounds per square inch.
In order to determine the maximum air pressure, I would add the range of air pressure that can be allowed in the tire from the recommended pressure.
recommended pressure + range of air pressure
41 + 2 = 43 pounds per square inch
This can be summarised with the equation: 41 ± 2

Answer:
57/99
Step-by-step explanation:
let's set up an equation:
x = 0.5757...
set up a second equation so the numbers after the decimal places are equal
100x = 57.5757...
subtract
100x = 57.5757...
- x = 0.5757
99x = 57
divide by 99
x = 57/99
Answer:
1/4
Step-by-step explanation:
2 1/2 * 1/10 = 1/4
The distribution is not a standard normal distribution.
We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.
Mathematically:
E(X) = 0 and V(X) = 1
Given that;
- the mean which follows a normal distribution (X) = 4.5338 g, and
- the standard deviation SD(X) = 0.1039 g
As such, the distribution is not a standard normal distribution.
Therefore, we can conclude that the distribution is not a standard normal distribution.
