You live near a bridge that goes over a river. the underneath side of the bridge is an arch that can be modeled with the function y= -0.000475x^2 + 0.851x, where x and y in feet. how high above is the river bridge (the top of the arch)? how long is section of bridge above the arch? a)the bridge is about 1,791.58 ft. above the river, and the length of the bridge above the arch is about 381.16 ft. b)the bridge is about 1,791.58 ft. above the river, and the length of the bridge above the arch is about 895.79 ft. c)the bridge is about 381.16 ft. above the river, and the length of the bridge above the arch is about 895.79 ft. d)the bridge is about 381.16 ft. above the river, and the length of the bridge above the arch is about 1,791.58 ft

Tcan be concluded that % of the seniors would prefer to see more candid pictures in this year's edition of the yearbook.

Two angles are complementary. the larger angle is 36 more than the smaller angle. what is the measure of the larger angle?

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
