Answer:
Step-by-step explanation:
Given that X the time to complete a standardized exam in the BYU-Idaho Testing Center is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
We have 68 rule as 2/3 of total would lie within 1 std deviation, and 95 rule as nearly 95% lie within 2 std deviations from the mean.
We have std deviation = 10
Hence 2 std deviations from the mean
= Mean ±2 std deviations
=±20
=
Below 50, 0.25 or 2.5% would complete the exam.
Hence missing value in the solution to the equation is:(-5,2)
Step-by-step explanation:
We are given the equation:
and we need to complete the missing value in the solution to the equation
(-5,?)
Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)
So, x= -5, Now finding y:
Putting value of x in given equation:
So, value of y is 2
Hence missing value in the solution to the equation is:(-5,2)
