Answer:
2x- 3y = - 6
Step-by-step explanation:
given
y -
x - 1 = 0
multiply all terms by 6 to eliminate the fractions
3y - 2x - 6 = 0 ( multiply all terms by - 1 )
- 3y + 2x + 6 = 0 ( subtract 6 from both sides )
2x - 3y = - 6 ← in standard form
Answer:
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
Step-by-step explanation:
Let
x ----> the unit cost of one toy reindeer
y ----> the unit cost of one box of cookies
we know that
----> equation A
----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is the point (3,2)
see the attached figure
therefore
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
A quantitative variable is a variable that can be measured i.e. quantified
There can be many sample means as possible
<h3>How to determine the number of samples</h3>
From the question, we understand that the variable is a quantitative variable
This means that the variable can be measured.
When a variable can be measured, there can be many sample means
Hence, the number of sample means is many
