Answer:

the perimeter = 9+\sqrt{2} +\sqrt{5}  \ units

Step-by-step explanation:

see the attached figure.

the perimeter of trapezoid JKLM = JK + KL + LM + MJ

The distance between two points (x₁ , y₁) and (x₂ , y₂)

= \sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2 }

Given the points L=(-7,4) , K=(-4,4) , L=(-2,3)  and M=(-8,3)

JK = \sqrt{(-7-(-4))^2+(4-4)^2 }= 3

KL = \sqrt{(-4-(-2))^2+(4-3)^2 }= \sqrt{5}

LM = \sqrt{(-2-(-8))^2+(3-3)^2 }= 6

MJ = \sqrt{(-8-(-7))^2+(3-4)^2 }= \sqrt{2}

So, JK + KL + LM + MJ = 3+\sqrt{5} + 6 + \sqrt{2}

So, the perimeter = 9+\sqrt{2} +\sqrt{5}  \ units

In a newspaper poll concerning violence on television, 589 people were asked, "What is your opinion of the amount of violence on
abruzzese [7]

Answer:

(a) P(Y'|M)\approx 0.3297

(b) P(Y|M')\approx 0.8323

(c) P(Y'|M')\approx 0.1323

Step-by-step explanation:

Given table is

                Yes      No      Don't Know      Total

Men          162      92             25               279

Women      258    41              11               310

Total          420    133            36                589

According the the conditional probability, if A and B are two event then

P(A|B)=P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}

We need to find the following probabilities.

Let Y is the event "saying yes," and M is the event "being a man."

(a)

P(Y'|M)=\frac{P(Y'\cap M)}{P(M)}

P(Y'|M)=\frac{\frac{92}{589}}{\frac{279}{589}}

P(Y'|M)=\frac{92}{279}

P(Y'|M)=0.329749103943

P(Y'|M)\approx 0.3297

(b)

P(Y|M')=\frac{P(Y\cap M')}{P(M')}

P(Y|M')=\frac{\frac{258}{589}}{\frac{310}{589}}

P(Y|M')=\frac{258}{310}

P(Y|M')=0.832258064516

P(Y|M')\approx 0.8323

(c)

P(Y'|M')=\frac{P(Y'\cap M')}{P(M')}

P(Y'|M')=\frac{\frac{41}{589}}{\frac{310}{589}}

P(Y'|M')=\frac{41}{310}

P(Y'|M')=0.132258064516

P(Y'|M')\approx 0.1323
