Y=20+35x because the 20 is a 1 time thing and 35x because 35 is charged each month
The Z-score is calculated by the formula below
Step 2: Substitute the given parameters in the formula
Hence, the z-score of a person who scored 145 on the exam is -0.5
Answer:
y = 18.38 + 0.0634x
Step-by-step explanation:
Given,
Monthly base charge = $18.38,
Also, the cost of each kilowatt-hours = 6.34 cents = $ 0.0634
( 1 cents = 0.01 dollars ),
So, the cost of x kilowatt-hours = 0.0634x,
If y represents the total monthly charge ( in dollars ) for x kilowatt-hours,
Thus, the total monthly charge for x kilowatt-hours = base charge + cost of x kilowatt-hours,
⇒ y = 18.38 + 0.0634x
Which is the required equation.
