In a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. a local man claims to be able to find water by "dowsing"—using a forked stick to indicate where the well should be drilled. you check with 80 of his customers and find that 27 have wells less than 100 feet deep. what do you conclude about his claim? a) write appropriate hypotheses. b) check the necessary assumptions. c) perform the mechanics of the test. what is the p-value? d) explain carefully what the p-value means in context. e) what’s your conclusion?

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

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'.
