The speed is 66.33 miles per hour
Step-by-step explanation:
Given
Total distance = 325 miles
They still have 126 miles to go. In order to find the distance they have covered, we will subtract the remaining miles from the total
So,
the car has been driving for 3 hours
So,
t= 3 hours
d = 199 miles
The speed is 66.33 miles per hour

Answer:
1.7030973451327434
Step-by-step explanation:
Step-by-step explanation:
Margin of error = critical value × standard deviation
We aren't given the critical value or any information to calculate it, so we need to make some assumptions. Assuming the data set is large enough to be approximated as normal, and that the confidence level is 95%, then the critical value is 1.96.
ME = 1.96 × 9.5
ME = 18.62
You may choose to round 1.96 to 2, in which case the margin of error is:
ME = 2 × 9.5
ME = 19
Answer:
1/4x -3
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y =4x+12
Exchange x and y
x = 4y+12
Solve for y
Subtract 12 from each side
x-12 = 4y+12-12
x-12 = 4y
Divide by 4
(x-12)/4 = 4y/4
The inverse is
1/4x -3
I would 100 because the more the trials means the more the results which means you get more of an accurate experiment then if you only did 10. Because since you have so many answers from all of the experiments you can conclude the correct answer from all of the experiments. I hope you get what I’m trying to say
