Hello from MrBillDoesMath!
Answer:
4 sin(70) which is approximately 3.76
Discussion:
sin(70) =
side opposite angle/ hypotenuse =
?/4.
As sin(70) = ?/4, multiplying both sides by 4 gives
? =4 sin(70) which is approximately 3.76
Thank you,

1/2 + 1/4 + 1/4 + 2/3 = 5/3
mean = 5/3 ÷ 4 = 5/12
The mean score is 3.08.
There is 1 quiz with score 1, so 1 point; 3 quizzes with score 2 for 3*2 = 6 points; 4 quizzes with score 3 for 4*3 = 12 points; 4 quizzes with score 4 for 4*4 = 16 points; and 1 quiz with score 5 for 5 points.
This is a total of 1+6+12+16+5 = 40 points.
This is out of 1+3+4+4+1 = 13 quizzes.
40/13 = 3.08
The following choices describe exponential growth:
