Answer: The test statistic to test the claim is .
Step-by-step explanation:
Let be the standard deviation of filled bottles.
As per given , we have
To fins test statistic , we use Chi -square test for population standard deviation:
, where n= sample size .
s= sample standard deviation.
We are given that , n= 20 and s= 0.11
Then,
Hence, the test statistic to test the claim is .
I am pretty sure that is impossible because 10 dimes and 9 nickles is 19 coins but is equal to $1.45, you would need another dime to make it $1.55 which means you would have 20 coins.
Answer:
62 sorry if i am wrong please dont report
Step-by-step explanation:
Answer:
the first one to solve for x is x=22-y
the first one to solve for y is y=22-x
the second one to solve for x is x=6+y
the second one to solve for y is y=-6+x
Step-by-step explanation:
in the first two you had to subtract y from both sides of the equation
the second one you had to add y to both sides of the equation to solve for x
but to solve for y you have to move all terms that dont contain y to the right side and solve
