Se realizó una serie de experimentos pasando 40 °c de aire sobre un cilindro largo de 25 mm de diámetro con una incrustación calentador eléctrico. el objetivo de estos experimentos era determinar la potencia por unidad de longitud requerida (w · / l) a mantener la temperatura de la superficie del cilindro a 300 °c durante diferentes velocidades del aire (v). los resultados de estos experimentos. se dan en la siguiente tabla:

Anyone know? is appreciated! will mark brainliest if correct!

Me find the value of x each figure.

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
