Z-score for 80% to pass = -0.842.
-60.624 = X - 426
X = 426 - 60.624
X = 365
Therefore the required passing score is 365.
-60.624 = X - 426
X = 426 - 60.624
X = 365
Therefore the required passing score is 365.

Answer:
Part 1) 300 miles
Part 2) 420 miles
Part 3) 600 miles
Step-by-step explanation:
we have
where
d(x) is the distance in miles
x is the time in hours
Part 1) How many miles will he have traveled after 3 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=3 hours
For x=3, d(x)=300
That means -----> After 3 hours Carlos has traveled 300 miles at a constant speed of 60 mph
Part 2) How many miles will he have traveled after 5 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=5 hours
For x=5, d(x)=420
That means -----> After 5 hours Carlos has traveled 420 miles at a constant speed of 60 mph
Part 3) How many miles will he have traveled after 8 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=8 hours
For x=8, d(x)=600
That means -----> After 8 hours Carlos has traveled 600 miles at a constant speed of 60 mph
