A)
if 39.99 is the 100%, what is 10 in percentage? well
solve for "x".
b)
now, with the discount, the amount is 29.99, thus if 29.99 is the 100%, what is 1.95 from it in percentage?
solve for "x".
c)
the original price is 39.99, the markup on that is 60%, how much is that?
well
now, after the discount, the price is 29.99, how much is 23.994 in percentage of 29.99?
well
solve for "x".
4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
<span>Partial products are different in regrouping in terms of how numbers are clustered from a set equation as a whole delivering it individual but naturally to all the numbers involved in the set. </span>
Regrouping is just like the commutative or associative property of numbers.
<span>Associative property of addition is used when you want to group addends. This is mainly used to cluster set of numbers or in this case, addends. How do you use the associative property when you break apart addends? Simple you group them using the open and closed parentheses or brackets. Take for an example 1 + 1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4 or 1 + (1 + 2) = 4 clustered into place.

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)
