I would use clustering to organize information when comparing and contrasting information. It allows you to explore the relationship between ideas.
Hope this helps
Answer:
And the 90% confidence interval would be between [566.80 and 579.20]
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=22 represent the sample standard deviation
n=36 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 0.90 or 90%, the significance would be and , and the critical value for this case would be
And replacing we got:
And the 90% confidence interval would be between [566.8033 and 579.1967]
Answer:
Price increase $1,947
Price of the next model $34,947
Step-by-step explanation:
Since the next model of a sport car will cost 5.9% more than the current model, and the cost of current model is $33,000
The price increase in dollars would be;
= 5.9% × $33,000
= $1,947
The price of the next model would be;
= Cost of current model + Price increase
= $33,000 + $1,947
= $34,947
V = (Base Area)(height)
V = (side)^2 * (height)
144 = 4^2 * h
144 = 16*h
h = 144/16
h = 9 cm. [ANSWER]
Answer:
8
Step-by-step explanation:
We use the equation for the percentage of solute concentration in a solution:
(1)
In this case the equiation (1) is transformed into:
(2)
n = number of times he must waves his wand to have a solution that is at least 34% DeMuggle juice.
Vpo = Initial volume of the magic potion = 2000ml
Vjo= Initial volume of DeMuggle juice = 30% * Vpo = (0.3)2000 = 600ml
Vb= Volume of a bottle = 25ml
Vjb = DeMuggle juice volume in a bottle = 75% * Vb = (0.75)25= 18.75ml
Vpmt = Total volume of the magic potion = 2000 + 25*n = Vpo + Vb * n
Vjt = Total volume of DeMuggle juice = 600 + 18.75*n = Vjo + Vjb * n
Replacing in (2):
Since the number of times the wand should be waved must be an integer, it approximates 8
Replacing n=8 in (1)
