Exercice n°2 : Une journée est composée de 24 heures.
1. Quelle fraction de la journée s'est écoulée :
a) à 6h, lorsque le réveil sonne ?
b) à 15h, lorsque Richard finit sa sieste?
c) à 19h, lorsque Samantha termine ses devoirs ?
Pensez à simplifier les fractions trouvées lorsque c'est possible.
2. Si une journée était divisée en 10 heures, une heure en 100 minutes et une minute en 100 secondes, quelle
heure serait-il lorsque le réveil sonne ? lorsque Bertrand prend son goûter ? lorsque Samantha termine ses
devoirs ?
3. Si une journée était divisée en 15 heures « normales », c'est-à-dire qu'une heure vaut 60 minutes et une minute
vaut 60 secondes, quelle heure serait-il lorsque Richard finit sa sieste?

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?

Me on this one i will give you 20pts. answer should be in detail . this is the discussion topic. one of the most fiercely debated topics in sports is the hot hand theory. the hot hand theory says that success breeds success. in other words, rather than each shot a basketball player takes or each at-bat a baseball player has being an independent event, the outcome of one event affects the next event. that is, a player can get hot and make a lot of shots in a row or get a lot of hits in a row. the hot hand theory, however, has been shown to be false in numerous academic studies. read this article, which discusses the hot hand theory as it relates to a professional basketball player. state whether you agree or disagree with the hot hand theory, and give reasons for your opinion. be sure to use some of the terms you’ve learned in this unit, such as independent event, dependent event, and conditional probability, in your answer.

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
