Answer:

There is a 20% probablity that the marble will be green :)

Step-by-step explanation:

  • There are a total of 10 marbles in the bag. 4 red+4 blue+ 2green=10
  • There are two green marbles out of the 10 marbles.  2/10
  • 2 divided by 10 is .20 or 20%
  • Therefore, there is a 20% probability that the marble will be green.

9= 2/3 (x+12) plz help
avanturin [10]

Answer:  x=3/2  

Step-by-step explanation:

Multiply the parentheses by 2/3.  9=2/3x+8.

Multiply  both sides by 3 .  27=2x+24

Move the term. When moved to the left side it changes from positive to a negative.  -2x=24-27.

-2x=-3

Divide both sides by -2

x=3/2   (x=1 1/2, x=1.5)

HELP PLEASE WILL GIVE BRAINLIEST WORTH 50 POINTS
Alja [10]

Answer:

y = 8.13 x -16125.713


hope it helps

Step-by-step explanation:

Sum of X = 14004

Sum of Y = 977

Mean X = 2000.5714

Mean Y = 139.5714

Sum of squares (SSX) = 53.7143

Sum of products (SP) = 436.7143

Regression Equation = ŷ = bX + a

b = SP/SSX = 436.71/53.71 = 8.13032

a = MY - bMX = 139.57 - (8.13*2000.57) = -16125.71277

ŷ = 8.13032X - 16125.71277
