The yearly cost for a non-member would be : y = 0.20x
Answer:
Step-by-step explanation:
a) The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
Carpetland salespersons average $8000 per week in sales. This is the null hypothesis.
H0: µ = 8000
Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increases the average sales per salesperson. This is the alternative hypothesis.
Ha: µ > 8000
b) A type I error occurs when a true null hypothesis is rejected.
In this situation, a Type I error would occur if it was concluded that the new compensation plan provides a population mean weekly sales greater than 8000 (correct) when in fact it does not.
c) a Type II error would occur if it was concluded that the new compensation plan does not provide a population mean weekly sales greater than 8000 when in fact, it does.
Answer:
B. x= 4
Step-by-step explanation:
We know that,
The result for the intersection of the secant and the tangent is given by by the figure below,
According to the question, we have,
i.e. 
i.e. 
Now, the solution of a quadratic equation 
is given by, 
So, we get,
implies a= 1, b= 12 and c= -64.
Thus, the solution is given by,
i.e. 
i.e. 
i.e. 
i.e. 
and i.e. 
i.e. 
and i.e. 
i.e x= -16 and x= 4.
Since, length cannot be negative.
So, we have, x= 4.
Answer:
0
Step-by-step explanation:
We can find the slope by using the slope function
m = (y2-y1)/(x2-x1)
= (-3 - -3)/(-2 - 6)
= (-3+3)/(-2-6)
= 0/-8
= 0
Answer:
Step-by-step explanation:
Simple, all you have to do is backwards equation. If the sum is 12. Subtract 12 by one of the numbers given.
