Walmart has received numerous customer complaints regarding the timeliness of their online orders. You are working in operations management for Walmart and are tasked with checking if these complaints are warranted. First, you decide to examine all the orders for those who purchased guaranteed two-day (48 hour) shipping. Since customers would not complain about early deliveries, you decided to test whether packages are arriving past or later than the 48-hour window. You pull company data on the 150 most recent deliveries and find an average delivery time of 48.62 hours and standard deviation of 3.85 hours.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
