What was the approximate number of mobile cellular subscriptions per 100 people in zimbabwe in 2003? the display gives the result of performing an exponential regression on a data set where the inputs are years since 2000 and the outputs are the corresponding mobile cellular subscriptions per 100 on zimbabwe. expreg y=a*b^x a=1.067905095 b=1.501755837 r^2=.9525580427 r= .9759908005 a. 2 b. 4 c. 6 d. 8

Just tell me how to set up the equation.

Fast! find the length of cu. the triangles are similar. show your work.

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
