5 7/10, and simplified is still 5 7/10.
It's an upside (-) down parabola. The axis of symmetry is the x coordinate of the vertex.
you can easily find this using formula: x= -b/2a
for parabola: ax² + b + c = 0
x = -16 ÷ 2(-4)
x = 2
Answer C
Answer:
2
Step-by-step explanation:
<span>To find the previous average sales, add the units sold in the same month in each of the last 4 years: 24 + 30 + 23 + 27 = 104. Then divide the sum by the number of different values, which in this case is 4. 104/4 = 26. Since sales goals are based on the previous average sales, you should expect to sell 26 units next month.</span>
