Answer:
4
Step-by-step explanation:
To find MEAN, add up <em>all</em> the values in a data set and then divide by the <em>number</em> of values.
6+2+7+3+2 = 20
Number of values in data set: 5
20÷5= 4
Answer:
(2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 2x + 3 → (1)
y = 3x + 1 → (2)
Substitute y = 3x + 1 into (1)
3x + 1 = 2x + 3 ( subtract 2x from both sides )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting x = 2 into (1)
y = 2(2) + 3 = 4 + 3 = 7
Solution is (2, 7 )
The answer is 7 1/3 hope it helps!
