Answer:
x= 5.6
Step-by-step explanation:
we will need to put the information we currently have into an equation:
10•2•x= 112
then multiply 10•2 which equals 20...then the equation wil turn out like this:
20•x=112
now you will isolate the x... but how?? dividing 20 by itslef.. cancelling it out, and if you do one thing to the other side of the equation, you have to do it to the other...
20/20•x=112/20
you will end up with x= 122/20
you can use a calculator for this step, but to practice long division... (check the screen shot thingie)
hope this helped !! ^^
Answer:
keiko- x
imelda- x+ 36
Sarah- x- 38
Step-by-step explanation:
- keiko is x since we have not been given his number of boxes.
- because imelda's number of boxes was 36 <em>more </em><em>than </em>keiko's, you will add the x which is for keiko and 36 for imelda(x+36).
- and sarah's number of boxes will be x-36 because we have been told her number of boxes is 38 <em>fewer </em><em>than </em> keiko's.
Answer:
The answer is C
Step-by-step explanation:
Straight angles means a line which straight and has no turning.
Step-by-step explanation:
since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is
So probabaility for 
is
So expected frequency for 
is 
(or 
.
