First we calculate the z-score for this situation.

Finding <em>P</em>(x < 5.3) is the same as finding <em>P</em>(<em>z</em> < -0.8). Using a table of standard normal distribution and z-scores we see that the probability is 0.21186.
Answer:
To find the values in each row, divide the values in the previous row by 4
Step-by-step explanation:
Answer:
90 degrees because it is a corner.... and it make a perfect right angle
Step-by-step explanation:
The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
