Answer:
The answer is B
Step-by-step explanation:
Distance formula- √(x2-x1)² + (y2-y1)²
Step 1: Plug in your values.
√(4a-a)² + (0-(-2b)²
Step 2: Substitute
√(3a)² + (2b)²
It cannot be simplified anymore, so your answer is:
B (√(3a)² + (2b)²)

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
