Answer:

Step-by-step explanation:
GIVEN: A car was sold
standard washed in a day , which was
of their total sales for that day.
TO FIND: Total amount of washes that the car wash sold that day.
SOLUTION:
Let the total sales of car washes sold for that day 
total number of standard car washes sold 
As, total standard car washes sold are
of total sales in a day

putting value in equation



Hence the total number of car washes sold that day are

Answer:
The interval that represents the middle 68% of her commute times is between 33.5 and 42.5 minutes.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 38 minutes, standard deviation of 4.5 minutes.
Determine the interval that represents the middle 68% of her commute times.
Within 1 standard deviation of the mean. So
38 - 4.5 = 33.5 minutes
38 + 4.5 = 42.5 minutes.
The interval that represents the middle 68% of her commute times is between 33.5 and 42.5 minutes.
Answer:
3 bulbs should be flawed
Step-by-step explanation:
2+ 18 = 20
20 bulbs were examined
2/20 = 1/10 were flawed
looking at the next 30 bulbs
30 * 1/10 = 3
3 of the next 30 bulbs should be flawed
