Atv show, linsay and tobias, recently had a share of 15, meaning that among the tv sets in use, 15% were tuned to that show. assume that an advertiser wants to verify that 15% share value by conducting its own survey, and a pilot survey begins with 10 householdes have tv sets in use at the time of a lindsay and tobias broadcast. a) find the probability that none of the households are tuned to lindsay and tobias. (round to three decimal places as needed)b) find the probability that at least one household is tuned to lindsay and tobias. c) find the probability that at most one household is tuned to lindsay and tobias. d) if a most one household is tuned to linday and tobias, does it appear that the 15% share value is wrong? why or wh not?

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

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'.

i would need to see the shape
