The data points represebt the number of swimmers at City Pool compared to the outside temperature (66, 8) (71, 23) (72 16) (75 30) (78 35) (80 24) (82 37) (86 37) (87 42) (90 50) Use the regression equation to determine how many swimmer will be at the pool when the temperature is 88F? Round to the nearest whole number

44 swimmers

Step-by-step explanation:

Given the data points :

66, 8) (71, 23) (72 16) (75 30) (78 35) (80 24) (82 37) (86 37) (87 42) (90 50)

Temperature X:

Number of swimmers Y:

Using the online regression calculator :

The regression model obtained is ;

ŷ = 1.5045X - 88.2056

Where

1.5045 = gradient or slope

-88.2056 = intercept

x = independent variable

y = dependent variable

Number of swimmers when temperature = 88

y = 1.5045(88) - 88.2056

y = 44.19

y = 44 (nearest whole number)

1/3 + 1/5 = 8/15.

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'.
