You subtract 1260 from 1964. Then you take that number and divide it by 8.
This gives you the answer of $88 per skull.
Line1: y = -x + 2
Line2: y = 2x - 1
Solution: (1,1)

-13
Step-by-step explanation:
it must be either -11 or -13. -13 is less than -12.
Answer:
Option A.
Step-by-step explanation:
In an experiment a mouse took the mean time to find its way through a maze = 18 seconds.
So the mean time μ = 18
So null hypothesis says,
H₀ : μ = 18
Then a researcher thought that the mice can complete the maze faster than the time taken earlier.
So he thinks mean time taken by 10 mice will be less than 18 seconds.
Or μ < 18
Alternate hypothesis says will be
Hₐ : μ < 18
Therefore, null hypothesis and alternate hypothesis will be
H₀ : μ = 18
Hₐ : μ < 18
Option A. will be the answer.
