Answer:
16
Step-by-step explanation:
So for QR is 1-(-3)=4
QT:|-2-2|=4
TS: |-2-(-2)|=4
RS: 2-(-2)=4
and they plus together is 4x
4x4 = 16
I hope this helps, have a blessed day. :D
Answer:
12.0
Step-by-step explanation:
solution:
Lets start with the most amount that could have been sold.......using guess and check, we can figure out that 290 salads could have been sold, while 8 cartons of milk would have been sold.
The least amount of salads that could have been sold were none.
so,
you have 0<s<290
at least none were sold, and at most 290 were sold
but I do believe you are missing part of the question

Answer with explanation:</h2>
Confidence interval for mean, when population standard deviation is unknown:
, where 
= sample mean
n= sample size
s= sample standard deviation
= Critical t-value for n-1 degrees of freedom
We assume the population has a normal distribution.
Given, n= 19 , s= 3.8 , 
A) Critical t value for 
and degree of 18 freedom
= 2.8784
B) Required confidence interval:
Lower bound = 19.9 years
Uppen bound = 24.9 years
C) Interpretation: We are 99% confident that the true population mean of lies in (19.9, 24.9) .
