Answer:
17.5
Step-by-step explanation:
According to the study 70% of the internet searches used Google as search engine.
Thus if the event X is the proportion of the searches using Google engine, then expected value of the event X, E(X) = 0.7
From here we can find the expected number of internet searches of a sample of 25 people by multiplying 25 and 0.7, i.e 25*0.7=17.5
A sixth is less than one half.
1/6 = 0.16
1/2 = 0.5
Answer:
31/20
Step-by-step explanation:
You need to plug in x as y-3.
so instead of 10x+10y=1 it is 10(y-3)+10y=1
Then just simplify the equation to find the value of y
3-7, 4-8, 2-6, and 1-5 are all corresponding.
It is .21 or 21 cents for each pound.
