Is expected that 90% of the time the temperature in Butterworth will be between 66.6 deg F and 85.37 deg F.
Step-by-step explanation:
The middle range of temperatures that occur on 90% of the days (upper limit and lower limit) can be calculated as:
For a 90% interval, z is equal to 1.6449,
Is expected that 90% of the time the temperature in Butterworth will be between 66.6 deg F and 85.37 deg F.
Answer:
Step-by-step explanation:
Given that total points required to make the playoffs = 20 points
As there is 2 points for a win,
so points earned for x win = 2x
Similarly, as there is 1 point for a tie.
so points earned for y ties = 1 y= y
Total points earned for x win and y ties = 2x+y
As the team makes the playoff so the total points of the team must be equal to or greater than 20 points (i.e the minimum points to make the playoff), so
Hence, the required equation is .
