A random sample of students at Bright University was asked to estimate the average number of minutes they spent online gaming per day and their SAT score. The data are shown in the table.
Minutes Spent Gaming Online 38 43 57 68 75 78 81 100 109
SAT Score 1320 1210 1190 1100 1000 980 960 950 830
A researcher wants to determine whether there is a negative relationship between the number of minutes spent gaming online each day and SAT score. What are the appropriate testing hypotheses?

1320, 950, and 830
Step-by-step explanation:
Ответ:
there you go :-
cos a = square root of (1- square of sin a)
tan = sin a / cos a = sin a/(square root of (1- square of sin a))
cosec a = 1/sin a
sec a = 1/cos a = 1/(square root of (1- square of sin a))
cot a = cos a /sin a = (square root of (1- square of sin a))/sin a
