In a sample of 5 of 800 t-shirts, were defective. based on this sample, in a production run of 250,000 how many would you expect to be defective?

Step-by-step explanation:

Given that the sample size was 800 t shirts.

Out of which 5 were found to be defective

Expected proporiton of defective shirts = 5/800 = 0.00625

This proportion will serve as an estimate for the next production run of 250000

Out of 250000 expected shirts to be defective = 250000*0.00625

=1562.50

=1563

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
