400+80+13 = 493 is the number.
Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
I guess you would isolate the variable. So switch the equation around to f=L/24
Answer: y = -x - 8
Step-by-step explanation:
