Answer:
<h2>$9.48</h2>
Step-by-step explanation:
The total amount for the order is
$9.75+$29.99+ $15.00=$54.74
let the money her mother owes her be x
so summing all the amount plus the balance given to her must equal $54.74
so x+40+5.26=54.74
solving fo x we have
x+45.26=54.74
make x subject of formula we habe
x=54.74-45.26
x=9.48

Answer:
And rounded up we have that n=421
Step-by-step explanation:
We know that the sample proportion have the following distribution:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by and . And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
We assume that a prior estimation for p would be since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=421
