You are doing a study on sleep deprivation. you take a sample of n = 25 individuals and deprive of them sleep so that they only get 4 hours of sleep for two nights. you then have them each solve a puzzle, and find that the mean time to solve the puzzle is m = 30 minutes. you know that for the population, the mean time to solve the puzzle is μ = 10 minutes and the standard deviation is σ = 20. you want to answer the following research question: does sleep deprivation have an effect on the amount of time it takes to solve this puzzle? what is the standard error of the sample mean

f

step-by-step explanation:

f

answer: youre the sweetest thing for that

the scale is 1/9 my friend can't simplify 1 anymore so it will be (for every 1 there's 9)

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.
