To multiply two (numbers to powers) . . . If the bases are the same,
then just keep the same base and add the powers.
To solve this problem, you just need to be able to add ' 5 ' and ' -2 '.
The answer is 'x' to that power.
Answer: a) 0.9544996
b) 0.9999366
Step-by-step explanation:
Given : The actual measured resistances of wires produced by company A have a normal probability distribution with mean
ohm and standard deviation
ohm.
Wires manufactured for use in a computer system are specified to have resistances between .12 and .14 ohms.
Let x be the random variable that represents the value of resistance in wires.
Using formula for z-score , 
The z-value at x= 0.12 will be

The z-value at x= 0.14 will be

The p-value : 

Hence, the probability that a randomly selected wire from company A’s production will meet the specifications = 0.9544996
b) Sample size : n= 4
Using formula for z-score , 
The z-value at x= 0.12 will be

The z-value at x= 0.14 will be

The p-value : 

The probability that all four in a randomly selected system will meet the specifications = 0.9999366
