The probability of a red marble is 25/250 or 1/10. The probability of a green marble is 50/250 or 1/5. The probability of a blue or orange marble is 175/250 or 7/10. Multiply the numerators and the denominators to get 7/500 probability (B)
6785 - 6496 = 289 units
289 x 13p = 3757p
3757p = £37.57
37.57 + 21.45 = £59.02
3/5
What you have to do is put 6 over 1 as 6/1, because all numbers are over one, then multiply the top and bottom numbers which is 18/5, and if you simplify that it gets you 3/5

Answer:
8x-3=17
Step-by-step explanation:
The term “less than” indicates that the 8x comes first in the equation because you’re taking 3 away from it
F(x)=-5(x-4)^2+80
f(x)=-5(x²-8x+16)+80
f(x)=-5x²+40x-80+80
f(x)=-5x²+40x
Replace f(x) to y, now switch the location of the variables x and y. Solve for new y.
y=-5x²+40x
x=-5y²+40y
0=-5y²+40y-x
Use quadratic formula to find the value of y.
y=-40+-√(40^2 -4(-5)(-x)/2(-5)
f^-1(x)= (-40+-√1600-20x)/-10 <--- Not too sure about this one :/
Hope I helped :)
