Answer:
The null hypothesis is rejected this means that 
The 95% confidence interval is 
Step-by-step explanation:
From the question we are told that
The standard deviation is s= 0.0001
The sample size is n = 25
The sample mean is 
The population mean is 
The null hypothesis is 
The alternative hypothesis is 
The test statistics is mathematically represented as
So the p-value from the z-table is mathematically represented as
seeing that
we reject the null hypothesis
The critical value of
obtained from the normal distribution table is
The margin of error is mathematically represented as
=> 
=> 
The 95% confidence level is mathematically represented as
=> 
=>
Answer:
A- m= 686 - 65h
B- h = 686 + 65m
C- m = 686 + 65h
D- h = 686 - 65m

Answer:
Step-by-step explanation:
If you want it in decimal form it should be 8.94427190.. and so on it wants it to the nearest hundredth so its just 8.94? I hope this helps the exact form not in decimal form is 4√5.
Answer: a. -3(x+1), b. 19-3x, c. -9 and d. 13
Step-by-step explanation:
Lets begin with a. (fog)(x)=f(g(x))
=f(2x+x+7), Note that 2x+x+7=3x+7
=f(3x+7) (where there is x if the function f(x) we
substitute x by 3x+7)
=4-(3x+7) =4-3x-7=-3x-3= -3(x+1).
b. (gof)(x)=g(f(x))=g(4-x) (where there is x in the function
g(x) we substitute with 4-x)
= 3(4-x)+7 = 19-3x
c. (fog)(2) = -3(2+1) = -9 (we now substitute x with 2 in -3(x+1). )
d. (gof)(2) = 19-3(2)=19-6=13. (Again we now substitute x with
2 in 19-3x)
I would divide 120 by 6 and get 20
