Answer:
444
Step-by-step explanation:
since 37/100 students liked chocolate you need to scale that data to the new data size and find thirty seven percent of 1200 which is 444
Find rates of change until you find a constant.
dy/dx=1,2,3,4,5,6
d2y/dx2=1,1,1,1,1
So the acceleration, d2y/d2x, is constant. This means that this is a quadratic sequence of the form a(n)=an^2+bn+c. So we can set up a system of equations to solve for the values of a,b, and c. Using the first three points, (1,1), (2,2), and (3,4) we have:
9a+3b+c=4, 4a+2b+c=2, and a+b+c=1 getting the differences...
5a+b=2 and 3a+b=1 and getting this difference...
2a=1, so a=1/2 making 5a+b=2 become:
2.5+b=2, so b=-1/2, making a+b+c=1 become:
1/2-1/2+c=1, so c=1 so the rule is:
a(n)=0.5x^2-0.5x+1 or if you prefer to not have decimals
a(n)=(x^2-x+2)/2

Answer:
908.6
Step-by-step explanation:
64.9x 14
-(-3 - 2) + (-5)
First solve inside the parentheses.
-(-5) + (-5)
Note the double negative sign in the front changes the -5 to a positive 5. Now your equation is:
5 + (-5) which is the same as 5 - 5.
So your answer is 0.
