The answer choices are not posted, but this is how you calculate the answer. Multiply $5.29 per yard by the total number of yards purchased.
= $5.29 per yard * 16.3 yards= $86.227
*or $86.23 rounded to the hundredths place
ANSWER: The exact answer is $86.227 for 16.3 yards. Not knowing the answer choices, you could estimate to $86.00, you could estimate to $86.23, you could even estimate to $90.00.
Hope this helps! :)
Answer:
267
Step-by-step explanation:
divide 1143 by 60, then multiply by 14
Answer:
The larger sample sizes gives a narrower confidence interval
Step-by-step explanation:
The larger sample sizes gives a narrower confidence interval, that is, a more "precise" estimation of the elections results.
In a confidence interval of proportions, we have that the lower end is given by:
In which is the probability of a sucess, is a value from the Z table and n is the length of the sample.
The upper end is given by:
As n increases, the difference between U and L decreases. This means that the confidence interval gets narrower.
Answer:
r = 4.1231055
Step-by-step explanation:
So to do this, you need to find the distance between the two points:
(-7,1) and (1,3).
To do this, the distance or diameter (d) is equal to:
d = sqrt ((x2-x1)^2 + (y2-y1)^2)
In this case:
d = sqrt( (1 - (-7))^2 + (3 - 1)^2 )
d = sqrt( 8^2 + 2^2)
d = sqrt( 64 + 4)
d = sqrt( 68 )
The radius is half of the diameter, so:
r = 1/2 * d
r = 1/2 * sqrt( 68 )
r~ 4.1231055
