The South African mathematician John Kerrich, while a prisoner of war during World War II, tossed a coin10,000 times and obtained 5067 heads.(2pts)a) Is this significant evidence at the 5% level that the probability that Kerrich’scoin comes up heads is not 0.5?Remember to specifythe null and alternative hypotheses, the test statistic, and the P-value. b) Give a 95% confidence interval to see what probabilities of heads are roughlyconsistent with Kerrich’s result.

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'.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

sorry i just need to anwers this to get points
