Since we are asked for tge graph that represent the total cost for the x numbers of lesson, it will be helpful to illustrate it first this way
for each lesson it will cost $30 dollars
1 lesson $30
2 lessons $60
3 lessons $90
4 lessons $120
5 lessons $150
So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati
Answer:
For 1 there is causationand there is correlation because they found that if people have a higher income, they will buy a more expensive plan so one cause another
the second question, there is no correlation because it doesn’t matter how many samples they provide, people still buy the same amount

The value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.
<h3>What is an Equation?</h3>
An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given that;
- √( 1 + (25/144) ) = 1 + (x/12)
First, we square both sides
√( 1 + (25/144) ) = 1 + (x/12)
(√( 1 + (25/144) ))² = (1 + (x/12))²
1 + (25/144) = 1 + ( x²/144)
Collect like terms
1 - 1 + (25/144) = ( x²/144)
25/144 = x²/144
We cross multiply
25 × 144 = x² × 144
Multiply each sides by 1/144
x² = 25
x = √25
x = 5
Therefore, the value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.
