Um estudante fez algumas provas em seu curso e obteve as notas 13, 34, 45, 26, 19, 27, 50, 63, 81,76, 52, 86, 92 e 98 a sua nota

Answer:
the mean is 54.428571428571<-------( what i think you are looking for )
the median is 51
the modes are 13, 19, 26, 27, 34, 45, 50, 52, 63, 76, 81, 86, 92, 98
Step-by-step explanation:
list all the numbers from greatest to least and the easiest way is to just cross them off left to right until you come up to one or two numbers. if one, that is your median. If two then add them up and divide them by two. We only had one, so the median is 51!
Hope this helped!
Answer:
$240
Step-by-step explanation: 12 x 20 = 240
Answer:
cos 2 x=1-sin^2 x
Step-by-step explanation:
x=-135°
cos 2x=cos (-270)=cos (-270+360)=cos 90=0
or cos 2x=1-2sin ²x=1-2(sin (-135))²
=1-2(-sin 135)²
=1-2(sin 135)²
=1-2(sin (180-45))²
=1-2(sin²45)
=1-2 (\frac{1}{\sqrt{2}})²
=1-1
=0
Answer:
68 %
Step-by-step explanation:
(a) Using the 68-95-99.7% rule, between what two lengths do the most typical 68% of all pregnancies fall?
95%? 99.7%?
The middle 68% of all pregnancies last between 266-16 and 266+16 days, 250 to 282. The middle 95% of all
pregnancies last between 266-2*16 and 266+2*16 days, 234 to 298 (for future reference, note that this “rule” is
rounded somewhat compared to the charts). The middle 99.7% of all pregnancies last between 266-3*16 and
266+3*16 days, 218 to 314.
