Trent and Devonte began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Trent took a test in Math and earned a 71.3, and Devonte took a test in Science and earned a 70.6. Use the fact that all the students' test grades in the Math class had a mean of 70 and a standard deviation of 9.5, and all the students' test grades in Science had a mean of 63.6 and a standard deviation of 9.1

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
