The Answer would be The first ab
Step-by-step explanation:
2x + y ≤ 10
<span>y ≤ - 2x + 10 → you can see the line in red </span>
<span>As the sign is ≤, you keep only the part below the red line, included the red line </span>
<span>2x - 4y < 8 </span>
<span>- 4y < - 2x + 8 </span>
<span>y > (- 2x + 8)/- 4 </span>
<span>y > - (1/2)x - 2 → you can see the line in blue </span>
<span>As the sign is >, you keep only the part above the blue line

Answer: First of all, we will add the options.
A. Yes, because 3 inches falls above the maximum value of lengths in the sample.
B. Yes, because the regression equation is based on a random sample.
C. Yes, because the association between length and weight is positive.
D. No, because 3 inches falls above the maximum value of lengths in the sample.
E. No, because there may not be any 3-inch fish of this species in the pond.
The correct option is D.
Step-by-step explanation: It would not be appropriate to use the model to predict the weight of species that is 3 inches long because 3 inches falls above the maximum value of lengths in the sample.
As we can see from the question, the model only accounts for species that are within the range of 0.75 to 1.35 inches in length, and species smaller or larger than that length have not been taken into consideration. Therefore the model can not be used to predict the weights of fishes not with the range accounted for.
It would be 2 2/25, so it would be d.
Answer:
x = 79°
Step-by-step explanation:
∠ABE = ∠BEF = 41° [Alternate angle ]
Now sum of angles of a triangle = 180°
Therefore,
∠EBF + ∠BEF + ∠BFE = 180°
60° + 41° + x = 180°
x = 180° - 60° - 41°
x = 79°
