Answer:
<em>Equation of the parabola x² = -12.56 y</em>
Step-by-step explanation:
<u>Explanation</u>:-
<em>Given Y- intercept ( 0, -3.14)</em>
<em>Given Focus is ( 0 , -a) = ( 0, -3.14)</em>
<em>So a = 3.14 center C(0,0)</em>
<em>The graph of the parabola is downwards and the axis of the parabola is Y-axis.</em>
<em>Equation of the standard parabola x² = -4 a y</em>
<em> x² = -4 (3.14) y</em>
<em> x² = - 12.56 y</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>Equation of the parabola x² = -12.56 y</em>

The dot plot shows the number of hours Stan worked each week for the last 3 months.
What fraction of the total number of weeks did Stan work 15 or more hours? Express in simplest form.
A. 5/7
B. 1/6
C. 1/5
D. 5/12
The image with the dot plot is attached.
Answer:
D. 5/12
Step-by-step explanation:
The dot plot shows the number of hours Stan worked and in order to know the number of weeks that he worked 15 hours or more, you have to count the dots that are between 15 and 18 hours. So, you have 3 dots in 15 hours, 1 dot in 16 hours and 1 dot in 18 hours. If you add this numbers (3+1+1=5), this means that he worked 5 weeks 15 or more hours. This number would be the numerator in your fraction. Then, the denominator would be the total amount of weeks and to find that you can count all the dots. The total number of dots is 12.
So, the fraction that represents the total number of weeks that Stan worked 15 or more hours is: 5/12. This is the simplest form because this numbers don't have any common factors other than 1.
