Please answer this !! Jackson has a bag that contains 5 blue socks, 7 pink socks, and 8 yellow socks.

Jackson removes a single sock from the bag 50 times. Each time he records the color of the sock that is drawn. He replaces the socks into the bag before the next draw.
How many blue socks would be expected to be drawn if 1000 pulls are conducted? 10,000 pulls?​

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
