Answer:
use substitution
(5 x 7) - (3 x 8) + 11= 35 - 24 + 11= 22
36 . how u it is easy when u add the both answers pa and on u will get 36 11%
+25%=36%
Answer:
2 hours
Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours

Where will the mean approach if sample size increase
Using central limit theorem, we have:
This means that; as n approaches infinity, the mean is almost expected to the 
i.e. expected to remain unchanged.
Hence, the mean value will approach 51.
