Answer: 27=3y
Let’s focus on the wording here.
Is= is in a math equation usually refers to equals. When a number is something, it equals something.
Times= Times in math refers to multiplication. When you times a number by something else, you multiply it.
Now knowing this, let’s substitute these symbols into the equation
27 is 3 times a number y
27=3•y
When with a variable, 3•y will usually just be left 3y. Let’s change this now.
27=3•y
27=3y
This is your final equation! Hope this helps comment below for more questions :)
Answer:
0.84 = 84% probability that the calculator has a good case and good batteries.
Step-by-step explanation:
We have these following percentages:
8% of a certain batch of calculators have a defective case.
11 % have defective batteries.
3% have both a defective case and defective batteries.
Using Venn Diagrams:
Event A: Defective Case
Event B: Defecitve Battery
So the probabilities are:
Probability of at least one problem:
Find the probability that the calculator has a good case and good batteries.
No problems, so
0.84 = 84% probability that the calculator has a good case and good batteries.
