2 lollipops, 2 chocolates, and 4 smarties
Answer:
B and C
Step-by-step explanation:
I will try i had this unit last year, basically the diameter is 5 in this problem, which you multiply by pi (in this case I will use 3.14 as the shortened version since its on-going) which gives you 15.7, then you multiply that by 3 in this problem to get 47.1!
Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
1 triangle: 40* is right to the 90*
2 triangle: 40* is left to the 90*
Hope this helped you!
Answer:
A.) -0.015x² + 0.365x + 1.116
Step-by-step explanation:
Using a graphing calculator, the quadratic regression equation obtained for the data in the table is :
General form of a quadratic regression equation :
A + Bx + Cx²
A = 1.115714
Bx = 0.3647x
Cx² = - 0.015x²
Hence, rounding to the appropriate number of decimal places, the quadratic regression equation becomes ;
-0.015x² + 0.365x + 1.116
