15 - 4t = 3
-15 -15
-4t = -12
-4t/-4 = -12/-4
t = 3
135 would be y intercept
10 would be slope
Equation: y = 10x + 135
Answer:the independent variable is x, the number of hours of work.
The dependent variable is y, the total charge for x hours of work.
Step-by-step explanation:
A change in the value of the independent variable causes a corresponding change in the value of in dependent variable. Thus, the dependent variable is is output while the independent variable is the input
For each visit, he charges $25 plus $20 per hour of work. The linear expression that represents the total amount of money that Ethan earns per visit is y = 25 + 20x.
Since the total amount charged, y depends on the number of hours of work, x, it means that the dependent variable is y and the independent variable is x
In the survey, 9 said they prefer the coffee shop next door out of 45 people total surveyed. This forms the fraction 9/45 = 1/5 which converts to 0.2 when you use a calculator or long division. In other words, 1/5 = 0.2
You'll then multiply the result of 0.2 by the total number of employees (250) to get...
0.2*250 = 50
So based on the results of the survey, we expect about 50 employees to say they prefer the coffee shop next door.
Answer: Choice B) 50
