Answer:
B) 0.57
Step-by-step explanation:
Let's define:
- B: the home has a desktop computer.
Data
We want to find the probability that a home has a laptop given that it has a desktop computer, that is, P(A|B).
P(A|B) = P(A∩B)/P(B) = 0.47/0.82 = 0.57

x represents how many are sold. then multiply 80×3

then add your x together

then you must divide your x by 3440

8 is how many higher-priced speakers take you 8 and multiple it by 3 to get how many lower-priced speakers

you have 24 low priced speaker and 8 high priced speakers.
They are not proportional because they do not have a constant ratio. If the data on the graph shows a curved line, it is not constant and is not proportional.
Answer:
1.2km is 400% of 300m
Step-by-step explanation:
1 km=1000m
So,1.2 km=1000*1.2=1200m
Let 1.2km(or 1200m) be x% of 300 m
By the problem,
300*x/100 = 1200
Or, 3x=1200
Or,x=1200/3=400
1.2km is 400% of 300m
