Answer:
The degrees of freedom are:
The confidence level is 0.95 or 95%, the significance would be and , the critical value for this case would be
And replacing we got:
Step-by-step explanation:
Information given
In order to calculate the mean and the sample deviation we can use the following formulas:
(2)
(3)
represent the sample mean
population mean
s=9.956 represent the sample standard deviation
n=10 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are:
The confidence level is 0.95 or 95%, the significance would be and , the critical value for this case would be
And replacing we got:
Answer: (8,0) and (0,-4)
Step-by-step explanation:
The x-intercept of an equation is when the equation touches the x-axis which is also where y = 0
So the x coordinate of the x-intercept is -2x + 0 = -16 as y = 0
x = 8 so the x-intercept is (8,0)
The y-intercept of an equation is when the equation touches the y-axis which is also where x = 0
So the y coordinate of the y-intercept is 0 + 4y = -16 as x = 0
y = -4 so the y intercept is (0,-4)
A number that can be divided by 4 that is less than 6 is 4 itself. After dividing 4 by 4, you will end up with 1.
