Answer:
The answer to your question is letter B
Step-by-step explanation:
Process
1.- Find two points of each line
Line A (-2, 0) (-1, 2)
Line B (-1. - 5) (-6, 0)
2.- Find the slope and equation of each line
Line A
m = 2
y - 0 = 2(x + 2)
y = 2x + 4
Line B
m = -1
y - 0 = -1(x + 6)
y = -x - 6
3.- Find the inequalities
Line A, we are interesteed in the lower area of the line, so the inequality is
y ≤ 2x + 4
Line B, we are also interested in the lower area of the line so the inequality is
y ≥ - x - 6
Considering that the data has no outliers, the mean of 3.2 inches should be used to describe the center of the data represented in this line plot.
<h3>What measure should be used to describe the center of a data-set?</h3>
It depends if the data-set has outliers or not.
- If it does not have outliers, the mean should be used.
- If it has, the median should be used.
The dot plot gives the number of times each measure appears. Since there is no outliers, that is, all values are close, the mean should be used. It is given by:
M = (2 x 1 + 3 x 2 + 2 x 3 + 1 x 5 + 1 x 6 + 1 x 7)/(2 + 3 + 2 + 1 + 1 + 1) = 3.2 inches.
The mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

<h3>Trina uses 3.44 or
pints of white paint</h3>
<em><u>Solution:</u></em>
Given that,
Trina uses 8.6 pints of blue paint and white paint to paint her bedroom walls
3/5 of the amount is blue paint, and the rest is white paint
From given,
3/5 of 8.6 pints is blue paint
Thus, 2/5 of 8.6 pints is white paint
<em><u>How many pints of white paint did she use to paint her bedroom walls?
</u></em>
Thus she uses 3.44 or 17.2/5 pints of white paint
We don't have the scatter plot
Answer:
9 stickers
Step-by-step explanation:
45/5=9
we divided 45 with 9 since __*5=45 and the figure out the__ we need to do the opposite operation(division)
