Subtract from both sides by 3/8, and u got -1/8. If u want to check put -1/8 in a
-1/8+3/8=1/4
I don't know but I think it is B) The slope is negative, and a linear model is a good fit for the data.
Answer:
a) The variable of interest is the students' preferred way/method of study.
b) The variable of interest is a qualitative variable.
Step-by-step explanation:
a) The survey was setup to investigate the preferred way of study for students in Orange County Community College.
Hence, the variable of interest is the students' preferred way/method of study.
b) Since this variable of interest cannot take on numerical values, it can only be expressed in qualitative means (in the different ways that students study), the variable of interest is a qualitative variable.
Hope this Helps!!!
The answer is $45
Let's make the system of equations.
x - the cost of the car
y - the amount Matthew has
<span>Matthew currently has enough money to buy 45 toy cars:
y =45x
</span><span>If the cost of each car was 10 cents less, Matthew could buy 5 more cars:
y = (x - 10)*(45 + 5)
45x = (x - 0.10) * 50
45x = 50x - 5
5 = 50x - 45x
5 = 5x
x = 5 / 5
x = 1
y = 45x = 45 * 1 = $45</span>
