Answer:
Step-by-step explanation:
I am assuming that you are asking what is [x] - 5 if f(86).
When you have this kind of question, what you do is to substitute the variable inside the parenthesis, so like what is says, f(x). If the question replaces the variable x with 86, that means you input the number into the equation.
So [x] - 5, if f(86).
Substitute:
86 - 5
Answer:
0.395
Step-by-step explanation:
The computation of the probability that none of the three shoppers purchased electronics is shown below:
So, first we have to determine the number of shoppers without considering the purchase i.e
= Total number of shoppers - electronics
where,
Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics
= 18 + 25 + 40 + 12 - 25
= 95 - 25
= 70
Now the probability is
= 
= 0.395
Answer:
Ryan practiced 33.66 minutes on Wednesday
Step-by-step explanation:
You do 43.2+37.48 and it equals 80.68
Then you do 114.34-80.68 which equals 33.66
Cycled 480 meters but a<span>fter cycling 0.25 of the distance Wendy stopped and waited for Rick to catch up
0.25 (480) = 120 meters
</span><span>Wendy cycled at a speed of 80 meters per minute = 120 /80 = 1.5 minutes
</span><span>Rick's speed was 20 meters per minute slower than Wendy's = 120 / 60 = 2 minutes
so </span>2 minutes - 1.5 minutes = 0.5 minutes
answer
<span>Wendy waited 0.5 minutes for Rick </span>
The answer to your question is,
Ed is 27. His brother is 9.
How did I get this answer?
Ed's age is twice that of his brother. So of course, when you divide 36 by 2, you would get 18. They are not twins so this wouldn't be the answer. You need to divide 18 by 2 again. This makes 9. If you add 9 to 27, that makes 36. Which is their ages.
