So the chance of getting 1 blue marble is 30% or 3/10, the chance of getting another in a row is also 3/10 since its asking for both youd do 3/10*3/10 = 9/100
Answer:
undefined
Step-by-step explanation:
The slope is found by using the formula
The points are (1,4) and (1,-3)
m = (y2-y1)/(x2-x1)
= (-3-4)/ (1-1)
= -7/ 0
When we divide by 0 the answer is undefined

find the gradient = change in y/change in X
-5 - -3/-3 - -6
= -2/3
take any two point say -3,-5 and equate to the gradient
Y - 5 /X - 3 = -2/3
cross multiply
3y - 15 = -2x + 6
3y = -2x +6 + 15
3y = -2x + 21
y = -2/3x +7
