Probability=desired outcomes/total possible outcomes

so
desired outcomes is the 'not wedding' photos
there are 4 vacation and 8 holiday
so 12 'not wedding' photos
12=desired outcomes


total outcomes is 13+4+8=25

so the probablity would be 12/25 or about 48%

Hello from MrBillDoesMath!

Answer:

x = 0, 7

Discussion:

f(g(x)) =

f ( x^2-7x) =

1/ ( x^2 - 7x)


The points NOT in the domain are those where the denominator,  x^2 - 7x = 0.

x^2 - 7x   = 0       =>       factor x from each term

x(x-7) = 0            =>        one or both terms must each 0

x = 0 or x =7


Thank you,

MrB

Number 8 please can you write and equation
tigry1 [53]
8.5x + 55 = 123

You would use the formula: mx + b = y

The slope is the amount of money each day(mx),and the y-intercept would be the fee(b) and the total cost would be y.
