C because each adult and youth times the money amount would be the total. So for instance 74(2)+35(2)=218 bc that's the total. Hope I helped.
Answer: (b) The focus of an ellipse is always located precisely at the center of the ellipse.
Step-by-step explanation:
An ellipse is defined as <em>"a closed curve with two axes of symmetry (major axis and minor axis) that results in cutting the surface of a cone by an oblique plane to the axis of symmetry with an angle greater than that of the generatrix with respect to the axis of revolution"</em>. That is why the ellipse is considered a conic figure.
To understand it better: an ellipse has two points on its major axis that are equidistant from the center , which are called foci, being this distance constant. In addition, the eccentricity allows to know how far the foci are from the center of the ellipse.
Therefore, the statement that indicates an ellipse has only one focus located precisely at the center is incorrect.
For the answer for number one you will multiply 3/4 and 9 and you will get 6.75 then you roun it to 6 for the answer.
For the answer for for number two postive 8 is to the right of zero so the opposite of 8 would be on the left of zero

Yo sup??
P(A|B)=P(A∩B)/P(B)
P(A∩B)=probability of finding a girl and is sophomore
P(B)=probability of finding a sophomore
P(A|B)=9/10
Hope this helps.
