The probability that a randomly selected student is a girl is 0.52, and the probability that a student is a girl and in an art c
DaniilM [7]

Answer: The answer is 0.38

Step-by-step explanation:

Well, everything is given, as stated in the question "the probability that a student is a girl and in an art class is 0.20."

It's given that the probability that a student is a girl is 0.52.

However, in the question, it said that it's given a student is a girl.

You have the probability that a student is a girl and in art class, so you need to find what 0.52 was multiplied by which would be the probability of someone being in art class. Knowing this you can do 0.20 / 0.52 to get 0.38.

-(x+3) = 2x-6 what is x
Makovka662 [10]

Answer:

x=1

Step-by-step explanation:

So, first you make sure to multiply the parenthesis by the negative so then it would be,

-x-3=2x-6

Then you add the -3 from the right to the other side

so, -x=2x-3

Then you want all the X variables to one side so you subtract the 2x to both sides.

so, -3x=-3

divide both by -3

x=1

Systems of equations with graphing
OlgaM077 [116]

Answer:

x= negative 1 and 2/5 y=1 and 3/5

Step-by-step explanation:

1. Start by putting both equations into slope-intercept form.  (y=mx+b)

-3x+3y=9

-3x+3x+3y=9+3x

3y=9+3x

3y/3=9+3x/3

y=3+x

2x-7y=-14

2x-2x-7y=-14-2x

-7y=-14-2x

-7y/-7=-14/-7-2x/-7

y=2+2/7x

2. Graph the equations and find where they intercept.
