These box plots show daily low temperatures for a sample of days in two different towns. A. The IQR for town A, 20°, is greater than the IQR for town B, 10°.

B. The standard deviation for town A, 20°, is greater than the standard deviation for town B, 10°.

C. The IQR for town A, 30°, is less than the IQR for town B, 43°.

D. The IQRS for towns A and B are both 30°.

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
