Answer:
y = 1000 x .30 (+ 1000)
Step-by-step explanation:
since it grows by 30%, you multiply .30 (the decimal version of 30%) and 1000 (your initial amount) to find how much it grows. Then you add $1000 at the very end, because that is how much you started with.
If the repairman work x hours, then he will charge $35 an hour, so the total of $35*x.
Add to the above amount the $50 we get $(50+35x).
The correct answer is then B.
Answer:
Step-by-step explanation:
30 minutes every three fourths of an hour
Answer:
So, the probability is P=0.094.
Step-by-step explanation:
We know that in a recent survey, 73% of the community favored building a police substation in their neighborhood.
We get that p=0.73 and q=1-0.73=0.27.
We calculate the probability that exactly 8 of them favor the building of the police substation, if 14 citizens are chosen.
We get that n=14 and k=8.
We calculate the probability:
So, the probability is P=0.094.
Answer: it shoudl be 5x - 9
Step-by-step explanation:7x - 14 - 2x + 6
but tbh im not sure
