Answer:

2/5

Step-by-step explanation:

There are 2 white and 4 yellow  = 6

P(yellow) = yellow /total = 4/6 = 2/3

We keep the ball

Now there are 2 white and 3 yellow  = 5

P(yellow) = yellow /total = 3/5

P ( yellow, keep, yellow) = 2/3 * 3/5 = 2/5

We are given 4 yellow balls and 2 white balls. In total, this adds up to 6.

Divide the number of yellow balls to the total number of balls:

4/6 -> 2/3

We are also given 3 yellow and 2 white.

Divide the number of yellow balls to the total number of balls:

3/5

Divide both fractions together:

3/5 * 2/3 = 6/15 = 2/5

Best of Luck!

The length of a rectangle is 3 less than 2 times its width. The area of the rectangle is 77 squared feet.
larisa86 [58]

Answer:

Let the Width(W) =X feet

then Length(L) = (2X-3)feet

Area of the rectangle (A)=77 square feet

A = L× W

L×W=A

(2X-3) × X = 77

2X²- 3X =77

2X²-3X -77=0

Solving it using the factorization method

2X²-14X+11X-77=0

(2X²-14X)+(11X-77)=0

2X(X-7) + 11(X-7)=0

(2X+11)(X-7) =0

When 2X+11=0

X= -11/2

When X-7=0

X = 7

Therefore X= 7

Width = X feet

= 7feet

The width is 7feet

Length = (2X-3)feet

= (2×7) -3)feet

=(14-3)feet

=11feet
