2. half or 1/2 or 3/6 if it is a 6 numbered die
Answer:
Step-by-step explanation:
Let be the average of the sample, and the population mean will be
We know that:
gr
Let be the standard deviation and n the sample size, then we know that the standard error of the sample is:
Where
In this case we are looking for:
This is:
or
Now we get the z score
Looking at the tables for the standard nominal distribution we get
1.50 x + 2 x = 10.50
add similar elements:
1.50 x + 2 x = 3.5 x
3.5 x = 10.50
x = 10.50 / 3.5
x = 3 magazines.
hope this helps!
Answer:
50
Step-by-step explanation:
because when we round off it to the nearest ten it is more nearest to the 50 than 60
You add extra zeroes until all numbers have the same quantity. in this case, 2.303 has three numbers after the decimal, so the other three number need it too. 2.300, 2.330, and 2.030. now that you have all of them looking the same now, you can tell which is least and work from there: 2.030 is the least, then 2.300, 2.303 then 2.330 is the largest.
