12) Consider a party balloon filled with helium with a small mass m hanging from it, as depicted in Figure 2. The balloon can be approximated as a sphere with volume V = 0.035 m. The mass of the rubber and string (i.e. the balloon's mass when it is not filled with helium) is 0.0025 kg. a) If the balloon with the mass hanging is floating in equilibrium, what is the value of the hanging mass?

You want to obtain a sample to estimate how much parents spend on their kids birthday parties. Based on previous study, you believe the population standard deviation is approximately o = 45.1 dollars. You would like to be 98% confident that your estimate is within 2.5 dollar(s) of average spending on the birthday parties. How many parents do you have to sample? Get help: Video Written Example

How would we estimate the average distance between molecules at
STP?
(e) Chemists often use the shorthand notation "STP' for standard temperature and pres- sure, or T = 273 K and P = 1.0 bar. What is the number density of an ideal gas at STP, nstp? Estimate the average distance between molecules at STP, in nanometers, and compare this to the size of a typical diatomic molecule (e.g., N2 or 02) of ~ 400 pm (1 pm = 10-12m).

answer asap please
A sealed balloon is filled with air at atmospheric pressure (P = 1.01 X 105 Pa) at 30°C (typical conditions for the surface of the Earth in St. Thomas). You take the (sealed) balloon with you on top of Mountain Top, which has an elevation of about 450m, where the average air pressure is 9.6 x 109 Pa. The temperature at the top is 26°C, a bit cooler. 2.5 pts. - a) How big is the balloon...

A
tire manufacturer would like to estimate the average tire life of
its new all-season light truck tire in terms of how many miles it
lasts. Determine the sample size needed to construct a 98%
confidence interval with a margin of error equal to 3,100 miles.
Assume the standard deviation for the tire life of this particular
brand is 7,000 miles.
