Answer:
Step-by-step explanation:
Given
Age 11 Age 12 Total
Girls 3 5 8
Boys 1 3 4
Required
The number of aged 12 children is:
The total number of children is:
So, we have:
Simplify
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 don't think there's any answer. It says that the absolute value of x-7 is negative 2, but an absolute value is always positive. So there's no value for x that can make the equation a true statement.
Answer:
$834.40
Step-by-step explanation:
Find how many kg Lulu has total by adding 43.50 and 43.50+25 together.
You get 112 kg, and then multiply that by the price per kg, so 112 * 7.45 is 834.40.
