360 / 3 = 120
120 hamburgers • 2 = 240 hotdogs
If n>4
Then n/4>7
I guess dis is the answer
Answer: The answer would be B. 
Because we know that she bought 6 bags of 36 jewels. So the first part we would need to solve would be the total number of jewel she purchased. Which would be 
. Then, you must find the total number of jewels that she used. Which would be 
. This means that the equaltion would be the total number of jewels-the total numnber of jewels used. Aka: 
1.3+4.2+2.8+5.9+8.1=?
3+2+8+9+1=23
carry the 2 over to the ones place
1+4+2+5+8=2=20
add the 2
22
drop the decimal
22.3m
The student T distribution would be used since we don't know the population variance (by extension the population standard deviation).
However, if n > 30, then the student T distribution is going to look very similar to the standard normal Z distribution. It won't be a perfect match, but it'll be close enough that it's more simple to use the Z distribution. With the Z distribution, you only have one set of values and you don't have to worry about the degrees of freedom.
