Try this solution (see the attachmed pictures), modify the design according to the local requirements.

Note, the points (-6;-16) and (-9;-28) are the intersection points of the parabola and the line, given in the condition.

Afina-wow [57]

Answer:

Step-by-step explanation:
The ratio or fraction for this problem would be 1 (gold coin) : 25 (points)

If we want to find out how many gold coins he needs to get 200 points we need to divide 200 by 25.

200/25 : 8

if we want to check our answer do this
1:25
1 x 8 is 8
25 x 8 is 200

Soo... Collin needs to find 8 coins to win 200 points.

Hope I was hopeful! <3

hoa [83]

Answer:

1) 1/4

3) 1/12

4) 5/6

Step-by-step explanation:

1) P(Red) = 1/4

4 options out of which 1 is red

Black --> Black, White, Yellow

Green --> Black, White, Yellow

Red --> Black, White, Yellow

White --> Black, White, Yellow

First 4 branches for buttons.

From each of these 4 branches, make 3 further branches for ribbons

3) In the tree diagram, there are

12 (4×3 = 12) equally likely outcomes

Out of which 1 is (Black, Black)

So, P(Black & Black) = 1/12

4) out of the 12 outcomes, only 2 have same colour of bottom ribbon:

(Black, Black) & (White,White).

Other 10 have different colours.

P(different) = 10/12 = 5/6
