Step-by-step explanation:
What you do first is the exponents 10^2 is 100
8.4 x 100 is 840 because when you multiply you move the decimal points the amount of zero's you have to the right but when you divide you do the opposite. You go left the amount of zeros there are.
Answer:
you are doing -4. so the first parenthesis -4(x+2x+1) is incorrect.

Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.
<h3>What is the uniform probability distribution?</h3>
It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.
The probability that Samantha has to wait less than 4.5 minutes to catch the bus is given by:

Answer:
The total distance cover by John is 15 min to reach his office .
Step-by-step explanation:
Given as ;
In the first 10 minutes , the distance cover is 1 miles every minutes
So, for 10 minutes , total distance cover by John = 10 × 1 = 10 miles
Again ,
John cover distance of 0.5 miles for every minutes , he travel for next 10 min
So, for next 10 min, total distance cover by John = 10 × 0.5 = 5 miles
So, The total distance cover by john = 10 miles + 5 miles = 15 miles
Hence The total distance cover by John is 15 min to reach his office . Answer
Answer:
c.
Step-by-step explanation:
Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.
We have $34x + $31.5(17 - x) = $558.
$34x + $31.5(17 - x) = $558
$34x + $535.5 - $31.5x = $558
$2.5x = $22.5
x = 9
Hence the answer is c.
