A = L * W........x = W
L = 2x + 3
A = 119

119 = x(2x + 3)
119 = 2x^2 + 3x
2x^2 + 3x - 119 = 0
(2x + 17)(x - 7) = 0

2x + 17 = 0
2x = -17
x = - 17/2 or - 8.5....wont work because it is negative

x - 7 = 0           L = 2x + 3
x = 7                L = 2(7) + 3
                        L = 14 + 3
                        L = 17

so the width (x) = 7 inches and the length (L) = 17 inches...
the equation used was : 119 = x(2x + 3)...or 2x^2 + 3x - 119 = 0...not sure which equation they want...but they are the same

(Ross 5.15) If X is a normal random variable with parameters µ " 10 and σ 2 " 36, compute (a) PpX ą 5q (b) Pp4 ă X ă 16q (c) PpX
pochemuha

Answer:

(a) 0.7967

(b) 0.6826

(c) 0.3707

(d) 0.9525

(e) 0.1587

Step-by-step explanation:

The random variable <em>X</em> follows a Normal distribution with mean <em>μ</em> = 10 and  variance <em>σ</em>² = 36.

(a)

Compute the value of P (X > 5) as follows:

P(X>5)=P(\frac{x-\mu}{\sigma}>\frac{5-10}{\sqrt{36}})\\=P(Z>-0.833)\\=P(Z

Thus, the value of P (X > 5) is 0.7967.

(b)

Compute the value of P (4 < X < 16) as follows:

P(4

Thus, the value of P (4 < X < 16) is 0.6826.

(c)

Compute the value of P (X < 8) as follows:

P(X

Thus, the value of P (X < 8) is 0.3707.

(d)

Compute the value of P (X < 20) as follows:

P(X

Thus, the value of P (X < 20) is 0.9525.

(e)

Compute the value of P (X > 16) as follows:

P(X>16)=P(\frac{x-\mu}{\sigma}>\frac{16-10}{\sqrt{36}})\\=P(Z>1)\\=1-P(Z

Thus, the value of P (X > 16) is 0.1587.

**Use a <em>z</em>-table for the probabilities.
