Answer:
8,000 - 24x
Step-by-step explanation:
Let
y ----> depreciated value of the car
x---> rate of depreciation
t ----> the time in months
we know that
The linear equation that represent this situation is
y=8,000-xt
For t=2 years=2*12=24 months
substitute
y=8,,000-x(24)
y=8,000-24x
Each variable that doesn’t have a number in front of it is an invisible 1. Since y, y, and y are like terms because they have the same exponent and variable. Because they are like terms you can add and subtract them. So 1y+1y+1y= 3y
Answer:
can it be a fraction

True, with certain foods, because of the way your body breaks them down, it will release a foul smell that will go away once it is metabolized.
Answer: True
Answer:
C. 50
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
The higher the margin of error, the wider an interval is.
As the sample size increases, the margin of error decreases. If we want a widest possible interval, we should select the smallest possible confidence interval.
So the correct answer is:
C. 50
