It is 1a over bd and 8 over k
Answer:
The confidence interval for this case would be (216.589, 223.411)
Step-by-step explanation:
Information given
represent the sample mean
population mean
s=12 represent the sample standard deviation
n=50 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.95 or 95%, the significance is 
and 
, the critical value for this case is 
And replacing we got:
The confidence interval for this case would be (216.589, 223.411)
Answer:
$23.60
Explanation:
you can make an equation out of the information provided! it will look something like:
12.5(.7)+13.5(1.1)
(12.5 is the amount of green ribbon and .7 is the cost per foot, so you would multiply them to find the total cost of the ribbon. do the same thing for the polka dot ribbon; 13.5 feet times 1.1, the cost per foot, will give u the total cost of polka dot ribbon. then, add them together for the total cost of both ribbons!!)
12.5×.7=8.75
13.5×1.1=14.85
8.75+11.85=23.6, or $23.60!!
Ans: C
To deduce this, plug in each of the vertices points into f(x,y) and see which one spits out the greatest number. It happens that f(4,6)=14 > f(3,1) > f(2,-2) > f(-2,3)
