Answer:
The ellipse is not the graph of a function.
Step-by-step explanation:
If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is <em>not a function</em>.
A vertical line will intersect the ellipse at two points (unless it is tangent to an end of the major axis), so the ellipse is not the graph of a function.
The population parameters that describe the y-intercept and slope of the line relating y and x are β₀ and β₁ respectively.
<h3>What is a
population model?</h3>
A population model can be represented by the equation:

Where μy is the population mean, β₀ is the y intercept and β₁ is the slope of the line
The population parameters that describe the y-intercept and slope of the line relating y and x are β₀ and β₁ respectively.

Answer:
B and C
Step-by-step explanation:
To figure out the average of all of the scores, you add all of the numbers together and then divide by how many numbers there are. The average shows about how well they did. Anne's friends average was 90 and was higher than Joan's friends average which was 75. Then the lowest score was definitely 78. So the answer would be B and C.
Answer:
(b) It is symmetrical about 
Step-by-step explanation:
Given

Required
True statement about the graph
First, we check the line of symmetric

Expand

Open bracket


A quadratic equation
has the following line of symmetry

By comparison, the equation becomes:



Hence, the line of symmetry is at: 
(b) is true.
64. 87.5% in fractions is 7/8. We divide 56 by 7/8, and get to 64.
56 ÷ 7/8= 56 x 8/7= 448/7, which is reduced into 64.
