Hence, the value of x is approximately 10.56
Answer:
+30
Step-by-step explanation:
1255- 1075 = 180
180 /6 = 30
Answer: d.) None of the answer choices is correct
Step-by-step explanation:
The homework score is an independent variable (known) and on the x-axis, while the midterm exam is the dependent variable, so it's on the y-axis
y = 0.91x - 94.4; and x=420
Substitute x as 420 into the equation.
y = 382.2 - 94.4 = 287.8, or approximately 288.
And this value isn't in the options above.
