Answer: The trip was 440 miles
Step-by-step explanation:
A girl scout leader rented a bus for a trip to the museum.
Let x represent the number of miles
traveled over 350 miles.
Let y represent the total cost of travelling x miles
The bus company charged $275 plus $.35 for each mile traveled over 350 miles. This means that for x miles, the cost will be
y = 275 + 0.35x
If the bus trip cost $429, it means that y = 429
To determine the number of miles,we will substitute y = 429 into the equation. It becomes
429 = 275 + 0.35x
0.35x = 429 - 275 = 154
x = 154/0.35 = 440
x = 440 miles

Answer:
c. 3.6 and 10.4 hrs
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviations of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean 7, standard deviation 1.7.
For about 95% of students, nightly amount of sleep is between
7 - 2*1.7 = 7 - 3.4 = 3.6 hours
7 + 2*1.7 = 7 + 3.4 = 10.4 hours
So the correct answer is:
c. 3.6 and 10.4 hrs
