Answer:
h(x) = 0.0045x – 0.4
Step-by-step explanation:
The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.
Flight A: f(x) = 0.003x - 1.2
Flight B: g(x) = 0.0015x + 0.8
Then the function
h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.
Therefore, the third option is the right option. (Answer)
First question: 12 people each play 11 times, so 12 * 11 = 132, there will be 132 matches if each player plays one match against each of the other athletes.
Answer:
the probability of the die landing on 4 is 4/6 or 1/3 and the probability of the card drawn from the deck is a heart is 13/52 or 1/4.
Step-by-step explanation:
For this question you have to find how many heartbeats are in 1 minute.
So if you divide 210 by 3 you get 70
So, my answer here would be. 70 heartbeats per minute
I'd arbitrarily begin by writing the factors 10 and 16. These, in turn, factor to 2 and 5. That's all we need to do here to form the product 160, using 5 once and 2 several times:
160 = 5 * 2^5
