Answer:

The expression of the other side of the rectangle = 2x + 4y + 25

Step-by-step explanation:

The Perimeter of the rectangle is 12 x + 8y

The one side of the rectangle is 4x - 25

Let the other side of the rectangle be S

Now, the PERIMETER OF THE RECTANGLE = 2 ( SUM of BOTH SIDES)

⇒  12 x + 8y =  2(S + (4x - 25))

or, 12 x + 8y =  2S +  8 x - 50

or, 12 x + 8y - 8x + 50 = 2S

⇒ 4x + 8y + 50 = 2S

or, S = 2x + 4y + 25

Hence, the expression of the other side of the rectangle = 2x + 4y + 25

My name is Ann [436]

Answer:

C. x 0 1 2 p(x) 0.35 0.60 0.05

Step-by-step explanation:

50% chance of survival

Let:

x = older eaglet survive

y = younger eaglet survive

Hence,

P(x = 0) (none of the eaglet survive)

P(x = 1) (only one survive)

P(x = 2) (both survive)

P(x) = 0.5

P(x') = 1 - 0.5 = 0.5

P(x n y) = 0.5 * 0.1 = 0.05 ( both survive)

P(only one survive)

P(y n x') + p(y' n x)

(0.5 * 0.3) + (0.5 * (1 - 0.1))

0.15 + 0.45 = 0.6

P(none survives)

1 - (0.60 + 0.05)

= 0.35

X _______ 0 ______ 1 ______ 2

P(x) ____ 0.35 ____ 0.60 ___ 0.05

On a number line, point S has coordinate 4.8 and point T has coordinate –2.3.
Ilya [14]

Answer:

The only answer that would work would be D) | 4.8 - ( -2.3) |

Step-by-step explanation:

This is because the distance is the absolute value of the difference of the two numbers. B and C would also work, but the 2.3 is not negative. A does not work because it is addition.
