Answer:
the student should score atleast 229 to be among the top 10%.
Step-by-step explanation:
in terms of the normal distribution, and if the table that you're using calculates the area of the normal distribution from the mean to a point x, only then what we are actually finding the value 'x' at which the z-score is at 40% (the rest 50% is already skipped by the table)

after finding the the value at this z-score, we can find the value of x at which the score is in the top 10% range.
we can find the z-score either using a normal distribution table or calculator. (but be sure what area is it calculating)
looking at the table the closest value we can find is, 0.4015 at z = 1.29 ((it is above 40% because we want to be in the top 10% range)




the student should score atleast 229 to be among the top 10%.
Answer:
Timed test.
Step-by-step explanation:
An operational definition gives exactly what the independent variable means and its mode of measurement. The Independent variable is the variable in a research or experimental study which causes a change in the the measured variable. Hence, the independent variable is the predictor variable. In the study above, the independent variable is the timed test which is used to observe changes in the heart rate of the test taker (test anxiety). The change innheartrate of the test taker is the dependent variable.

Answer:
(c) (4, 3)
Step-by-step explanation:
The next step in the solution of System B is to divide by 15 1/2. This will result in the equation ...
x = 4
The only answer choice that has x = 4 is the ordered pair (4, 3). That ordered pair is the solution to the system.

(15 1/2)x = 62 ⇒ (31/2)x = 124/2 ⇒ x = (124/2)/(31/2) = 124/31 = 4
