The given final course grade, 88%, is the average of Frank's four quarter grades. The average is the sum of all grades divided among the four quarters. Let x be the average,
(82.5 + 94.7 + 87.9 + x) / 4 = 88
The value of x is equal to 86.9. Thus, the answer is letter C. 87%.

Step-by-step explanation:
we see 2 confirmed points with whole integers as coordinates.
(-2, -1) and (1, 2)
the general equation for a line is
y = ax + b
a is the slope expressed as y/x ratio indicating how many units y changes , when x changes for a certain amount of units when going from one point to another.
so, when going from (-2, -1) to (1, 2)
x changes by +3 units (from -2 to 1)
y changes by +3 units (from -1 to 2)
so, the slope (a) is 3/3 = 1
b is the y-intercept (the y value when x=0, so, the point where the line crosses the y-axis).
our equation looks now like this
y = x + b
to get b we use the coordinates of one of the points as x and y. e.g. (1, 2) :
2 = 1 + b
b = 1
the full equation is
y = x + 1
In your graphing calculator, you can press 2nd then cos to create cos^-1 and then press 0.5967.
You’re basically doing arccos(0.5967) or cos^-1(0.5967)
Remember to put your calculator into radian mode first.
Your answer will be 0.9314138684 in radian
For degrees it would be 53.36608364
