Answer:
Dude the hard hope someone help
Step-by-step explanation:
Start with the general formula. The key word is difference. So the general formula is
D(x) = W(x) - R(x) Now substitute in the values for W(x) and R(x)
D(x) = 0.002x^3 - 0.01x^2 - (x^2 - 4x + 13) Be very careful about the sign in front of the brackets.
D(x) = 0.002x^3 - 0.01x^2 - x^2 + 4x - 13 Do you see what that minus sign did? It affected all 3 terms.
D(x) = 0.002x^3 - 1.01x^2 + 4x - 13 <em>Note: -0.01 - 1x^2 = - 1.01 x^2</em>
That gives you a clear cut answer
C<<<<< answer.
That sign is the worst part of the question. Make sure you understand what it did.

Answer: 72
Answer:
Katrina got 86 in her test
Step-by-step explanation:
given
mean = 80
standard deviation = 3
z-score = 2
Let score of Katrina = x
Recall z-score is calculated by
z-score = (x-mean) / standard deviation
substitute values and solve for x
2 = (x-80)/3
x-80=6
x = 86
