Answer:
A. The data set has an outlier
Step-by-step explanation:
The data set has an outlier because 100 is the largest number of the set.
Let the cost of 1 notebook be x and the cost of 1 binder be y.
4 notebooks and 3 binders would cost 23.5
Therefore, 4x + 3y = 23.5 (1)
7 notebooks and 6 binders would cost 44.5
Therefore, 7x + 6y = 44.5 (2)
Multiply the first equation by 2.
8x + 6y = 47 (3)
(3) - (2) gives
x = 2.5
Substitute the value of x in (1), we get,
4(2.5) + 3y = 23.5
10 + 3y = 23.5
3y = 23.5 - 10
3y = 13.5
y = 13.5/3
y = 4.5
Hence, cost of 5 notebooks and 3 binders is:
5x + 3y = 5(2.5) + 3(4.5)
= 12.5 + 13.5
= 26
Hence, cost of 5 notebooks and 3 binders is $26.
Answer:
Option B (1,10)
Step-by-step explanation:
we have
we know that
If a ordered pair is on the graph of f(x) then the ordered pair must satisfy the function f(x)
<u><em>Verify each case</em></u>
case A) (0,0)
For x=0
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is not on the graph of f(x)
case B) (1,10)
For x=1
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is on the graph of f(x)
case C) (0,10)
For x=0
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is not on the graph of f(x)
case D) (10,1)
For x=10
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is not on the graph of f(x)
