158572 is the answer heres my work (((2 x 7 x 1 x 8) / 4) x 2 x 9) + 4 - ((273 x 1.8) / 1.4) + (200 x 3 x 8) + 43 + (500 x 30 x 3) + (382 x 283) + (932 / 2) = thats how you do it
To ease the understanding, let's write it in degrees and not in Radian:
Formula of conversion: Degree°/180 = Radian/π
Convert 7π/4 in degrees: = (7x180)/4 = 315°
This angle is in the IV th Quadrant of the UNIT circle. So you can write 315° or - 45° .
sin(7π/4) = sin(315°) = sin( - 45°) = - sin(45°) = - (√2)/2
Answer: I don't think so because they can only see it when you turn it in. Trust me I have kami too.
Tje answer to your question is 5.2
So the modal value is most commonly known as mode, or the most common number in a data set. So the most common number in this stem-and-leaf plot is 137
The modal value is 137
Hopes this helps!
