Stefan's law of radiation states that the radiation energy of a body is proportional to the fourth power of the absolute temperature t of a body. the rate of change of this energy in a surrounding medium of absolute temperature m is modeled as follows: 1. dt k(m4 - t4)where k > 0 is a constant let k = 0.05, m-3 t(0) = 4 estimate t (1) using euler's method with a step size of 0.25 and a step size of 0.1. explain the results.

Given the following sampling distribution of one mean with a sample size 49, from a normally distributed population,find the population standard deviation, o.79828588912497

Michelle and julie work at a catering company. they need to bake 264 cookies for a birthday party that starts in a little over an hour and a half. each tube of cookie dough claims to make 36 cookies, but michelle eats about 1/5 of every tube and julie makes cookies that are 1.5 times as large as the recommended cookie size.it takes about 8 minutes to bake a container of cookies, but since julie's cookies are larger, they take 12 minutes to bake. a. how many tubes should each girl plan to bake? how long does each girl use the oven? b. explain your solution process what did you make? c. what assumptions did you make?
