Step-by-step explanation: standard score is equal to sample mean - population mean all over standard deviation.
Z=×-u/sigma. Where sigma is standard deviation. 267985-254876=13109. 13109/5834=2.247. Therefore the standard score is 2.247. The price they paid for the house is usual.
Answer:
480.20
Step-by-step explanation:
since she profits from the initial amount by 134.60 we add both amounts
345.60+134.60=480.20
F(x) = x + 2
when x = 1, f(1) = 1 + 2 = 3
Therefore range for x ≠ 1 is y ≠ 3.
