Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13

Answer:
Step-by-step explanation:
The general vertex form of parabola is,
where,
is the vertex,
is the axis of symmetry.
Given the coordinates of the vertex as and focus as
a is the 4 times the distance between the vertex and the focus.
The distance between the vertex and focus is -3. Negative is because we are calculating the distance to the left (-ve x direction) of the vertex.
Hence,
Putting the values in the general equation,
i.e
