Based on the scatter plot on perishable and nonperishable items purchased by customers, the following is true:
- Purchased 5 nonperishable items - 3 people.
- Median number of perishable items = 7 perishable items.
- People bought same number of perishable and nonperishable = 2 people.
<h3 /><h3>What does the scatterplot show?</h3>
Looking at the y-axis which shows the number of nonperishable items bought, the number of dots we find at 5 is 3 which means 3 people bought 5 nonperishable items.
The median of perishable items requires that we order the perishable items bought:
2, 2, 5, 6, 7, 8, 9, 10, 11
The median is 7 perishable items.
The number of people with the same number of perishable and nonperishables are 2 people.
One purchased 8 nonperishables and 8 perishables and the other purchased 9 of both items.

They will each have to give $21.60 because 129.60/ 6 is 21.6 which is $21 and .60 cents each
Answer:
x > -3 and y ≥ 1/2x - 2
Step-by-step explanation:
blue line = x > -3
red line = pass (0, -2) (4, 0)
y = 1/2x - 2

Answer:
10x . . . . . (Note the sign of the middle term is negative. 10x goes in the box.)
Step-by-step explanation:
The sum of the two roots is ...
... (5 -3i) +(5 +3i) = 10
In a quadratic with leading coefficient 1, the coefficient of the 1st-degree term is the opposite of the sum of the roots. Here, that means the middle term is -10x. The minus sign is given, so the answer is 10x.

<em>How Do We Know?</em>
When "a" and "b" are roots of a quadratic in x, it has factors (x -a)(x -b). The product of those two factors is ...
... (x -a)(x -b) = x² -(a+b)x +ab
Here, that means the product of the factors (5 -3i)(5 +3i) is ab = 34, which it is. Their sum is (a+b) = 10, so the x-term is -(a+b)x = -10x.
