Mean can also be thought of as average.
Standard deviation is a bit more difficult to describe. It is a statistic that can help measure how spread out the data gets.
Depending on the distribution, data within 1 standard deviation of the mean can be considered fairly common and expected. Essentially it tells you that data is not exceptionally high or exceptionally low.
Answer: x=−5 or x=5
Step-by-step explanation:
−3x4+27x2+1200=0
Step 1: Factor left side of equation.
−3(x2+16)(x+5)(x−5)=0
Step 2: Set factors equal to 0.
x2+16=0 or x+5=0 or x−5=0
x=−5 or x=5
A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.
In Kg it’s 2.56 so multiply that by 1000 which gives you 2650 grams. :)
