Answer:
equation form: x=-131/8y -31/40
Step-by-step explanation:
this is addition/elimination
1. x=-3 y=4 2. x=5/2 y=15/2 3. x=9/5 y=-36/5 4. x=-2 y=1
The correct answer is A.
Horizontal shift is obtained by addition/subtraction a number to every occurrence of x in the equation. Addition indicates a shift towards left and subtraction indicates a shift towards right.
So the correct answer is Subtract that number From.
Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-

, where
= Sample mean ,
= population mean,
= population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,

Hence, the z-score = 2.46
