Astudy was done to determine the stress levels that students have while taking exams. the stress level was found to be normally distributed with a mean stress level of 8.2 and a standard deviation of 1.34. what is the probability that at your next exam, you will have a stress level between 9 and 10?

0.1841

Step-by-step explanation:

Given: Mean :

Standard deviation :

The formula to calculate z-score is given by :_

For x= 9, we have

For x= 10, we have

The P-value =

Hence, the probability that at your next exam, you will have a stress level between 9 and 10 = 0.1841

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

the diver is 33 feet below the surface.
