Answer:
7 hours
Step-by-step explanation:
25.75(total cost of the rental)
-10.00 (cost of initially renting the bike)
----------------
15.75$ (cost of hourly fees)
15.75/2.25(hourly rate) = 7
Suppose the line is y=mx+b
when x=3, y=15, so 15=3m+b
when x=-1, y=-13, so -13=-m+b
solve the system of these two equation, you get m=7, b=-6
so the linear equation is y=7x-6
price of cycle = 3600 Rs
if the price is reduced by 20%, the price will be:
3600 - (20/100*3600) = 3600 - (20*36)
= 3600 - 720
= 2880 Rs
if the price is further reduced by 1/4 (25%),
2880 - (25/100*2880) = 2880 - 720
= 2160 Rs
Therefore, if the price is reduced first by 20% and this is further reduced by 25%, the final price after reduction will be 2160 Rs.
Answer:
The number 0.507 is a statistic parameter and population proportion as it states the proportion since the beginning (historically).
Step-by-step explanation:
If you calculate it and it gives you stats then that makes it a statistic parameter, you have sample of 45 newborns and you multiply with 0.40 (out of hundred) you get 18 boys which just the sample proportion of the set given.
If you multiply it with 0.507, it just gives about 22.81500 which just estimates that for every set of 45 babies you would get about 22 boys average.
Answer:
b.
Step-by-step explanation:
everything under x= 2 is x+1 meaning x<2 and at 2 it starts x+2
