Step-by-step explanation:

The given query seems to be incomplete. Please find below the attachment of the full query.

By using the Bayes' theorem, we get

⇒  P[(X

By putting the values, we get

                                     =\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}

                                     =\frac{(0.20+0.15)}{1-0.20-0.30}

                                     =\frac{0.35}{0.5}

                                     =0.70

Hayley is considering two gym membership plans. The plans are detailed here.
Novosadov [1.4K]

Option 2: y = 3x+50 is the right answer

Step-by-step explanation:

We have to convert the details given in Plan one to an equation

Let x be the number of visits to the gym

and y be the total cost for plan one

So,

As each visit costs $3, x number of visits will cost 3x

One time fee is $50

So the equation can be written as:

y = 3x+50

Hence

Option 2: y = 3x+50 is the right answer
