Answer:the z score is - 1
Step-by-step explanation:
Assuming a normal distribution for the delivery time of sandwiches by Sammy's Sandwich Shop. We would apply the formula for normal distribution which is expressed as
z = (x - u)/s
Where
x = delivery times
u = mean delivery time
s = standard deviation
From the information given,
u = 25 minutes
s = 2 minutes
We want to determine the z-score for the number of sandwiches delivered in less than 23 minutes. It becomes
z = (23 - 25)/2 = - 1

The total amount of his commission for these vehicles is $ 1686
<em><u>Solution:</u></em>
Given that,
Miles earns a 6% commission on each vehicle he sells
Therefore,
Commission rate = 6 %
Today he sold a truck for $18,500 and a car for $9,600
Therefore,
Commission amount = 6 % of (18500 + 9600)
Commission amount = 6 % of 28100
Calculate the above equation

Thus the total amount of his commission for these vehicles is $ 1686
I believe it 16/225 in fraction form
The original answer for that question would be 303.55. The best estimate when you round to the nearest tenth the approximate answer would be 303.6 because the 5 in the hundredths place rounds the 5 in the tenths place to a 6. So the approximate answer would be 303.6....hope this helps.
