Answer:
part A 1.68
part B 29.67
Step-by-step explanation:
First you multiply $39.99 dollars and 0.30 = $11.9970 you round this to $12.00
After you apply the discount $39.99 - $12.00 = 27.99
Next you must multiply 27.99*0.06 =1.6794 and round to 1.68 to get tax
Last you add $27.99 and 1.68 to get a total of $29.67 for the headphones
Plz give brainliest i didnt look it up.
First solve the original number of pictures. The original
number of picture is 108 + 32 – 13 which is equal to 127 pictures. Then solve
the size of each picture,
12021.1 kb / 13 pic = 924.7 kb / pic
So the original storage is 127 pic ( 924.7 kb / pic) =
117,436.9 kb

Answer:
The 88% confidence interval for the proportion of defectives today is (0.053, 0.123)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
88% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 88% confidence interval for the proportion of defectives today is (0.053, 0.123)
