Given the data as shown in the table below
x y
54 0.86
42 0.93
66 0.85
74 0.87
92 0.73
calculate the correlation coefficient of xx, and yy using any technology with advanced "stats" feature.
r= . (round to 4 decimal places.)

Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

Drag each expression to the correct location on the solution. not all expressions will be used. consider the polynomial 8x + 2x2 - 20x - 5. factor by grouping to write the polynomial in factored form.
