the answer is 20 I believe (i'm so sorry if i'm wrong.)
Answer:
0.40
Step-by-step explanation:
Step 1:Draw lines to represent the first set of options in the question (in our case, 3 factories). Label them (our question list A B and C so that is what we’ll use here).
Step 2: Convert the percentages to decimals, and place those on the appropriate branch in the diagram. For our example, 50% = 0.5, and 25% = 0.25.
Step 3: Draw the next set of branches. In our case, we were told that 70% of factory A’s output was passenger. Converting to decimals, we have 0.7 P (“P” is just my own shorthand here for “Passenger”) and 0.3 NP (“NP” = “Not Passenger”).
Step 4:Repeat step 3 for as many branches as you are given.
Step 5: Multiply the probabilities of the first branch that produces the desired result together. In our case, we want to know about the production of passenger places, so we choose the first branch that leads to P.
Step 6: Multiply the remaining branches that produce the desired result. In our example there are two more branches that can lead to P.
Step 6: Add up all of the probabilities you calculated in steps 5 and 6. In our example, we had:
.35 + .0625 + .0625 = .475
That’s it!
I think the answer is Y=4+5/4x
First you need to convert 1 1/3 into an improper fraction by multiplying 1 by 3, and then adding 1 to get 4/3. 13 can be written a 13/1, and the rule for fractions is to multiply across, so you get 13/1 × 4/3, which equals 52/3. This can't be simplified down, but it can be rewritten as a mixed number of 17 1/3. I hope this helps!
