Guide Steve will conduct a survey to determine the number of times per year that people in the United States shop for clothing.
Which sample should Steve use to get results that are the most representative of the total population?
A random sample of 1,000 people from 10 local clothing stores.
O A random sample of 1,000 people from his city.
O A random sample of 1,000 people from his state.
d A random sample of 1,000 people from each of the 50 states.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
