Answer: The fifth grade is 86
Step-by-step explanation:
Given that there are five grades, let the missing fifth grade be represented by x:
84 +79 +82 +88 + x /5 = 83.8
333 + x/5 = 83.8
Next, we cross multiply:
333 + x = 83.8 x 5
333 + x = 419
Subtract 333 from both sides of the equation to get the value of x
333 + x - 333 = 419 - 333
x = 86

Answer:

Step-by-step explanation:
To find the function, compare the y values. Notice that each y value decreases by being divided by 4. This means the base of the exponential is 1/4.
To find the initial value, consider the point (0,0.5). When 1/4 is raised to the 0 power, the value is 1. This leaves that the initial value is 1/2 since 1/2*1 = 0.5.
The function is
