A new design for the braking system on a certain type of car has been proposed. For the current system, the true average braking

distance at 40 mph under specified conditions is known to be 120 ft. It is proposed that the new design be implemented only if sample data strongly indicates a reduction in true average braking distance for the new design. State the relevant hypotheses, and describe the type I and type II errors in the context of this situation.

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2
dangina [55]

Answer:

irrational

Step-by-step explanation:

A = s^2

s^2 = 24,200

s = \sqrt{24200}

s = \sqrt{242 \times 100}

s = \sqrt{100 \times 121 \times 2}

s = 10 \times 11\sqrt{2}

s = 110\sqrt{2}

P = 4s

P = 4 \times 100 \sqrt{2}

P = 440 \sqrt{2}

The perimeter is irrational.

\frac{(x + 1)(x - 1)}{(x + 3)(x - 3)}  \times  \frac{(x + 3)(x + 5)}{(x - 1)(x + 4)}  =  \frac{(x + 1)(x + 5)}{(x - 3)(x + 4)}

Find the points of intersection of the graphs of the equations.
AURORKA [14]

Answer:

To find the point of intersection, just solve for x and y in the equations

so since x - y = -5

x = y - 5

now that we have a value of x, we will substitute x with in in the other equation

<em>5x + 3y = -9</em>

<em>5(y-5) + 3y = -9</em>

<em>5y - 25 + 3y = -9</em>

<em>8y = 16 </em>

y = 2

now use this value of y in the equation we made for x

<em>x = y - 5</em>

<em>x = 2 - 5</em>

x = -3

Hence, the point of contact is (-3 , 2)
