Step-by-step explanation:

Let's define:

  • A: the home has a laptop
  • B: the home has a desktop computer.

Data

  • P(B) = 0.82
  • P(A∩B) = 0.47

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

Alex_Xolod [135]

190x +80(3x) = 3440
x represents how many are sold. then multiply 80×3
80 \times 3 = 240
then add your x together
190x + 240x = 430x
then you must divide your x by 3440
3440 \div 430 = 8
8 is how many higher-priced speakers take you 8 and multiple it by 3 to get how many lower-priced speakers
8 \times 3 = 24
you have 24 low priced speaker and 8 high priced speakers.

Express 1.2 km as a percentage of 300 m
Effectus [21]

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
