Answer: 22
Step-by-step explanation:
4 - (-18) = 4 + (+ 18) = 22
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.
9.327 rounds to 9.3
5.72 rounds to 5.7
4132 rounds to 4132
9.3 + 5.7 + 4132 =
15 + 4132 = 4147
