2x=35
x=17,5
That the answer
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
To solve this, you need to know slope-intercept form;
Where mx is the slope and b is the y-intercept form.
Now, looking at the values you have been provided, you can just plug them into the formula.
X=log36/(2*log15)
X=aprox 0.6616
No solution.
2y-x=6 =y=1/2x+3
Since 1/2x does not equal 1/2x+3, this is a false statement and therefore has no solution
