Answer:
The 99% confidence interval for the population mean is 22.96 to 26.64
Step-by-step explanation:
Consider the provided information,
A sample of 49 customers. Assume a population standard deviation of $5. If the sample mean is $24.80,
The confidence interval if 99%.
Thus, 1-α=0.99
α=0.01
Now we need to determine 
Now by using z score table we find that 
The boundaries of the confidence interval are:

Hence, the 99% confidence interval for the population mean is 22.96 to 26.64
Y=2x+1 is the right answer to this
Answer:
$15
Step-by-step explanation:
use a calculator and type 25%x12 and you will get 3
so 3 is 25% of 12
add 12 and 3 together to get your answer. $15
All you do is add up all your sides! So if your shape has 4+4+5+5 = 18. All you do is add them up!
2p-1q is the answer
5p+2q-3p-3q
isolate the variables:
5p-3p+2q-3q
simplify:
2p-1q
that is the answer!
hope I helped! :)
