FrozenT [24]

Answer:

28.26 square inches

Step-by-step explanation:

Formula for area of a circle:

$A=\pi r^2$

Radius is 3.

$A= \pi (3)^2\\A=\pi 9$

Use 3.14 for pi:

$A = 3.14 * 9 = 28.26\\A=28.26$

The area should be 28.26 square inches.

Simplify fully: X^2+3x-4/ 2x^2-5x+3

sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step 1 :

Simplify —

Equation at the end of step 1 :

((((x2)+3x)-(2•x2))-5x)+3

Step 2 :

Equation at the end of step 2 :

((((x2) + 3x) - 2x2) - 5x) + 3

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-x2 - 2x + 3 = -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2 Factoring x2 + 2x - 3

The first term is, x2 its coefficient is 1 .

The middle term is, +2x its coefficient is 2 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3

Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is 2 .

-3 + 1 = -2

-1 + 3 = 2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and 3

x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-1)

Add up the last 2 terms, pulling out common factors :

3 • (x-1)

Step-5 : Add up the four terms of step 4 :

(x+3) • (x-1)

Which is the desired factorization

Final result :

(-x - 3) • (x - 1)

Answer: see answers below

Step-by-step explanation:

(i) The first leaf of the tree is: black = 5/9 and white = 4/9

That means that there are 5 black marbles out of 9 total marbles and 4 white marbles out of 9 total marbles.

Total marbles = 9

Black marbles = 5

White marbles = 4

*******************************************************************************************

(ii)

P(B₂/B₁)

The probability that the 2nd marble is black given that the 1st marble was black.

P(W₂/B₁)

The probability that the 2nd marble is white given that the 1st marble was black.

P(B₂/W₁)

The probability that the 2nd marble is black given that the 1st marble was white.

P(W₂/W₁)

The probability that the 2nd marble is white given that the 1st marble was white.

***********************************************************************************************

(iii) Outcomes (iv) Probability

(B, B) (5/9) x (1/2) = 5/18

(B, W) (5/9) x (1/2) = 5/18

(W, B) (4/9) x (5/8) = 5/18

(W, W) (4/9) x (3/8) = 3/18

Check: Total = 18/18 = 1 $\checkmark$

**********************************************************************************************

(iv) Dependent

Once the first ball is drawn, there is one less ball for the second draw. Therefore, the second draw is dependent on the first draw.
