Answer:
y = -4/5x + 2/5
Step-by-step explanation:
Slope form of an equation is y = mx + b
Sub in x and y coordinates and slope then isolate for b
-2 = -4/5(3) + b
-2 = -12/5 + b
-2 + 12/5 = b
b = -10/5 + 12/5
b = 2/5
Sub in b and the slope into the slope form equation
y = (-4/5)x + 2/5
The graph shows the maximum residual is ...
◉ Data point (10, 10); Residual = 4.50_____
Apparently, this question makes no use of the line of best fit.
Percentage is out of 100, so in this case we have a fraction of 4/10.
Answer:
Angelina should buy 9 packs of pens and 8 packs of pencils.
Step-by-step explanation:
Each pack of pens = 8 pens
Each pack of pencils = 9 pencils.
Also we know that, Commutative Property of Multiplication states that
a x b = b x a for any two numbers a and b.
So, 8 x 9 = 72 = 9 x 8
Hence, she should buy 9 packs of pens, so she will have 9 x 8 = 72 pens.
And she should buy 8 packs of pencils, she will have 8 x 9 = 72 pencils.
