Given that the diameter: d= 0.0625 inch.
So, radius of the wire : r = 
= 0.03125 inch
Now the formula to find the cross-sectional area of wire ( circle) is:
A = πr²
= 3.14 * (0.03125)² Since, π = 3.14 and r = 0.03125
=3.14 * 0.000976563
= 0.003066406
= 0.00307 (Rounded to 5 decimal places).
Hence, cross-sectional area of a wire is 0.00307 square inches.
Hope this helps you!
Answer:
It is the distance of x from zero. Examples:The absolute value
of 5 is 5.
The absolute value of -10 is 10.
(Complex numbers) The absolute value of 4 + 3 is 5.
Step-by-step explanation:
Answer:
za/2: Divide the confidence level by two, and look that area up in the z-table: .95 / 2 = 0.475. ...
E (margin of error): Divide the given width by 2. 6% / 2. ...
: use the given percentage. 41% = 0.41. ...
: subtract. from 1.
Answer:
37
Step-by-step explanation:
Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;
(x1 - x2) ± Margin of error
Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.
From the question ;
x1 = 1150 ; x2 = 1113
Hence, the point estimate is : (1150 - 1113) = 37
