I think the answer would be A
Nothing too complicated here, you're just finding points on the line.
For the first one, the missing blank is 2
For the last one, the missing blank is 18
To find these, just look whether the provided number is on x or y, then go along either the x or y axis to find that number. Then go in the other direction until you hit the line, and your answer should be there. The full table is:
x | y
2 | 6
4 | 12
6 | 18
<u>Vertex form of the quadratic equation</u>
The vertex form of the quadratic function has the following equation:
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The parabola is given as:
Comparing with the equation:
a=2, Vertex: (3,4)
The graph of the parabola is shown in the image below
<span>b.This is a dilation about (0, 0) with a scale factor of 4; A’(8, 4), B’(16, 4), C’(16, –12).</span>
the customer's expected value of the cellphone insurance policy is -$38.64. (Option C)
Based on the data given, 585/5000 or 11.7% of the total number policies have claims. This means, 100% - 11.7% = 88.3% have not claimed their cellphone insurance.
- In the chart, we are focusing on the customer's end because the question is asking for the customer's expected value↓
- In the chart, if the customer has no claims, then he losses his $48. However, if he has claims, he gains $32 since $80 - 48 = $32. Also, based on the data given by the company, 88.30% have no claims and only 11.7% of the customers have claims.
- To get the expected value, we will multiply -48 and 88.3% as well as 32 and 11.7%. 48 is negative because it indicates a loss.
Therefore, your Answer is -38.64
