The regional transit authority for major metropolitan area wants to determine whether this relationship between the age of a bus
1 answer:
Answer Answer:
The scatter plot indicates that a positive linear relationship exists between the age of a car and its maintenance cost. This is depicted by the positive slope direction which indicates the maintainance cost of the car is will increase as the age of the car increases. If the correlation Coefficient of the data was calculated, a correlation Coefficient value of about 0.934 will be obtained.

Approach 1: Mathematical Approach
Domain is the possible inputs or x values of a function
Here we can use any x values greater than or less than 7. We can also use 7 since their is a a function defined for x greater than or equal to 7.
So the domain is (-♾, ♾).
The range is possible y values. Since we can use negative x values, if we plug in x values for the function -5/7x+1, we are going to get positive numbers, as we plug in higher negative numbers, our range is bigger.
This means the range is bounded to -4 so our range is
(-4,♾)
Approach 2: Graphical Approach
Above is the graph
It can take any x values so the domain is (-♾, ♾).
The range is (-4,♾).
Answer:
The quotient is (x² + 2x - 2)
The dividend is (2x³ + 7x² + 2x + 9)
The remainder is 15
The divisor is (2x + 3)
Step-by-step explanation:
- The quotient is the answer of the division
- The dividend is the part before (above) the division sign (bar of the fraction)
- The divisor is the part after (below) the division sign (bar of the fraction)
- The remainder is the part left over in a division problem
The relation between them is dividend ÷ divisor = quotient +
Ex: 37 ÷ 5 = 7 + , where 37 is the dividend, 5 is the divisor, 7 is the quotient and 2 is the remainder
Let us solve the problem
∵
∵ dividend ÷ divisor = quotient +
- Compare the rule by the given problem
∴ The quotient is (x² + 2x - 2)
∴ The dividend is (2x³ + 7x² + 2x + 9)
∴ The remainder is 15
∴ The divisor is (2x + 3)
