Here goes nothing lol
Car 1 depreciates $3,164 each year
Car 2 depreciates $1,225 each year
after 5 years car 1 depreciates $15,820
after 5 years car 2 depreciates $6,125
The total value of car 1 in 5 years is $7,320
The total value of car 2 in 5 years is $11,375
The difference is $4,055
Answer:
t ≈ 13.26
Step-by-step explanation:
We are given;
x¯ = 20 minutes per day
μ = 17 minutes per day
sample standard deviation; s = 1.6 minutes
Sample size; n = 50
When σ is unknown, formula for test statistic is;
t = (x¯ - μ)/(s/√n)
t = (20 - 17)/(1.6/√50)
t = 3/0.2263
t ≈ 13.26
We can create such equation to solve your problem
where x is variable which we want to know.
To solve this we can just divide 600 by 10 to see what the number we want.
600:10=60
The result is 60
