Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the square. Only answe

wel

Answer:

$0.07$

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the square is equal to divide the area of the square by the area of rectangle

Let

x-----> the area of square

y----> the area of rectangle

P -----> the probability

$P=\frac{x}{y}$

Find the area of square (x)

$A=5^{2}=25\ in^{2}$

Find the area of rectangle (y)

$A=25*15=375\ in^{2}$

Find the probability P

$P=\frac{25}{375}=0.07$

When a parabola represented by the equation y - 2x 2 = 8 x + 5 is translated 3 units to the left and 2 units up, the new parabol

amid [387]

First rewrite y - 2x 2 = 8 x + 5 as

y = 2x 2 + 8 x + 5 

Complete square and determine vertex.

y = 2(x 2 + 4x + 4) - 8 + 5 

= 2(x + 2) 2 - 3 

vertex at (- 2 , - 3) 

If parabola is translated 3 units to the left and 2 units up its vertex is also translated 3 units to the right and 2 units up .

vertex after translations is at: (-2 - 3 , - 3 + 2) = (-5 , -1)
