Answer:
1/5
Step-by-step explanation:
-2(-2)^4 + 5(-2)^2 - 4
-2(-2)= 4. 4^4= 16
5(-2)= -10. -10^2= 100 - 4= 96
96 + 16= 112
Answer: 112
Based on the information given, it should be noted that the residual for the two points will be 0.087 and -0.033 respectively.
<h3>How to find the residual.</h3>
From the complete information, the predicted value for the point (3, 0.42) will be:
= (0.091 × 3) + 0.060
= 0.0273 + 0.060
= 0.333
Therefore, the residual will be:
= 0.42 - 0.333 = 0.087
The predicted value for the point (3, 0.3) will be:
y = 0.091x + 0.060.
= (0.091 × 3) + 0.060.
= 0.333
Therefore, the residual will be:
= 0.3 - 0.333 = -0.033
Therefore, the residual for the two points will be 0.087 and -0.333 respectively.

Answer:
Step-by-step explanation:
<u>If p is the original price, the markdown price is:</u>
- p - 20% =
- p - p(20/100) =
- p - 0.2p =
- 0.8p
<u>Now, another 20% off:</u>
- 0.8p - 20% =
- 0.8p - 0.8p(20/100) =
- 0.8(p - 0.2p) =
- 0.64p
<u>Answer choices:</u>
- A. 0.2(1p-0.2p)
- B. 0.6p
- C. (1p-0.2p)-0.2p
- D. 0.8p(1p-0.2p)
Correct one is D
