Well. add all of these up 8+5+5. we know 5+5 is 10. and 10+8 is 18. so 18 is the denominator. There are 8 red markers and 5 blue markers at 8 and 5 up. 8+5 is 13 right? So the numerator will be 13. but the probability of picking a blue then a red is 13 alone or if you are ask for out of the amount of markers there are, its 13/18. so the probability is 13 or 13/18.

Please help ASAP!ill give brainliest !

The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y= $\frac{7}{9}x^2+3$

as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3

the equation can be written as : $\frac{x^2}{25}+ \frac{y^2}{9} =1$
