Answer:
1.11 mm
Step-by-step explanation:
The height of a cylinder can be found using the formula: h=V/(πr^2)
This formula was found by taking the formula for the volume of a cylinder and solving for h, or height. Knowing that V is 126 and the radius is 6, we can plug in our known variables in order to solve for h.
Answer: Question 1.1: It is 1.5 standard deviations away from the mean.
Our value of 26 is 6 units about the mean of 20. If each standard deviation is 4, we just divide 6 by 4. This gives us the number of standard deviations.
Question 2.2 The correct answer is -0.52
If we are 0.52 standard deviations below the mean, then our z-score is simply -0.52. The definition of a z-score is the number of standard deviations from the mean.
Answer:
35/8
Step-by-step explanation:
1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4.
So 1 3/4 ÷ 2/5 = 7/4 × 5/2 = 35/8.
You start by subtracting: 16000-1200= 14800
Then you divide 14800 by how many feet the plane rises per minute
14800/945=16 minutes
The answer is 16 minutes
