Answer:
Step-by-step explanation:
A group of 2 hot dogs and 1 soda makes a group of 3 items. There were ...
234/3 = 78
groups of items sold.
Since there is 1 soda in the group, that's 78 sodas. The number of hot dogs is 2 times that, or 156 hot dogs.
78 sodas and 156 hot dogs were sold.
Fist convert the equation to vertex form
y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106
So the vertex is at (-7,-106)
Mean
add up numbers and divide by how many there are
(1+1+5+3+6+6)/7=3 and 2/3
