2, –6 is the correct answer
My GUT is telling me its A.
as you can see the points are in a vertical line going up increasing 2 points to the right vertically..
I think its A.
Please correct me if I'm wrong!
I hope this helped.
Answer:
y=7x+4
Step-by-step explanation:
Answer:
a

b

Ca
Cb
Explanation:
From the question we are told that
The sample size is n = 100
The upper limit of the 95% confidence interval is b = 47.2 years
The lower limit of the 95% confidence interval is a = 34.5 years
Generally the sample mean is mathematically represented as

=> 
=> 
Generally the margin of error is mathematically represented as

=> 
=> 
Considering question C a
From the question we are told the confidence level is 90% , hence the level of significance is
=>
The sample size is n = 22
Given that the sample size is not sufficient enough i.e
we will make use of the student t distribution table
Generally the degree of freedom is mathematically represented as

=> 
=> 
Generally from the student t distribution table the critical value of
at a degree of freedom of 21 is
Considering question C b
From the question we are told the confidence level is 80% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Answer:
The simplified expression is: 5/2
Step-by-step explanation:
//5^-3 = 1/(5^3)
(2^2*5^6)/(5^3*2^3*5^2)=
(2^2*2^-3)*(5^6*5^-3*5^-2)=
(2^-1)*(5^1)=
5/2=
