Foot Locker uses sales per square foot as a measure of store productivity. Last year, the mean annual sales per square foot was $410 with a standard deviation of $54.38. Suppose you take a random sample of 36 Foot Locker stores operating last year. There is a 3% probability that the sample mean annual sales per square foot is at most $.

answer: true

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
