Answer: For 
Nick does not has enough money to follow this recommendation.
Step-by-step explanation:
Given: A self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that.
Let y be the cost for car wash for m minutes then
such that at m= 5 , y=4 which is the cost for car wash (dollars) for first 5 minutes.
Also, A car enthusiast magazine recommends spending at least 15 minutes to properly wash a car.
For
But Nick has $10 which is less than $11.5, so he does not has enough money to follow this recommendation.
Answer:
f(g(x)) = x² - 2x + 1
Step-by-step explanation:
To find f(g(x)), substitute x = g(x) into f(x) , that is
f(g(x))
= f(x - 1)
= (x - 1)² ← expand using FOIL
= x² - 2x + 1
Step-by-step explanation:
The required sum
=(1+2+3+...+199)−(3+6+9+...+198)−(5+10+15+...+195)+(15+30+45+...+195)
=2199(1+199)−266(3+198)−239(5+195)+213(15+195)
=199×100−33×201−39×100+13×105=10732
Answer:
B
Step-by-step explanation:
Dean recorded the results of spinning the spinner 60 times:
- Number 1 spun 12 times
- Number 2 spun 17 times
- Number 3 spun 15 times
- Number 4 spun 16 times
The <u>experimental probability</u> is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
Find all experimental probabilities:
Hence, option B is correct
