I think it means like explain what are variable is. Only if your finding a variable: explain how you got the answer to that variable. Hope I helped!
Answer: The graph will move 9 spaces to the right.
Answer:
The correct option is a
Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
The sample size is n = 9
The null hypothesis is 
The alternative hypothesis is 
The level of significance is 
The sample mean is 
Generally the test statistics is mathematically represented as

=> 
=> 
From the z table the area under the normal curve to the right corresponding to 1.2 is

Generally the p-value is mathematically represented as

=> 
=> 
From the value obtained w can see that
hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is there is not enough evidence to support the claim
The correct answer is d.We have the following system of linear equations:
(I)

(II)

Let's use the elimination method, then let's multiply the equation (1)

and subtracting (I) and (II):
(I)

∴

(I)

(II)

____________________
(III)

∴

We can find the value of x by substituting y either in (I) or (II). Thus, from (I):

∴

∴

∴

∴

Let's substitute the values of x and y into (I) and (2)
(I)

(II)

Finally the answer is:
