Answer:

$120.

Step-by-step explanation:

Just multiply 4 by 5 since it makes 20. Since we know that the price for 4 people is $24, you multiply 24 by 5 since you are paying for 20 people.

It’s 120 all you have to do is divide 24 by 4 to get how much it would be for one person then you multiply that by 20 and you get 120

Let Y be a random variable with a density function given by

Neporo4naja [7]

From the given density function we find the distribution function,

$F_Y(y)=P(Y\le y)=\displaystyle\int_{-\infty}^y f_Y(t)\,\mathrm dt=\begin{cases}0&\text{for }y$

(a)

$F_{U_1}(u_1)=P(U_1\le u_1)=P(3Y\le u_1)=P\left(Y\le\dfrac{u_1}3\right)=F_Y\left(\dfrac{u_1}3\right)$

$\implies F_{U_1}(u_1)=\begin{cases}0&\text{for }u_1$

$\implies f_{U_1}(u_1)=\begin{cases}\frac{{u_1}^2}{18}&\text{for }-3\le u_1\le3\\0&\text{otherwise}\end{cases}$

(b)

$F_{U_2}(u_2)=P(3-Y\le u_2)=P(Y\ge3-u_2)=1-P(Y$

$\implies F_{U_2}(u_2)=\begin{cases}0&\text{for }u_2$

$\implies f_{U_2}(u_2)=\begin{cases}\frac32(u_2-3)^2&\text{for }2\le u_2\le4\\0&\text{otherwise}\end{cases}$

(c)

$F_{U_3}(u_3)=P(Y^2\le u_3)=P(-\sqrt{u_3}\le Y\le\sqrt{u_3})=F_Y(\sqrt{u_3})-F_y(\sqrt{u_3})$

$\implies F_{U_3}(u_3)=\begin{cases}0&\text{for }u_3$

$\implies f_{U_3}(u_3}=\begin{cases}\frac32\sqrt u&\text{for }0\le u\le1\\0&\text{otherwise}\end{cases}$

Please help!! I need all I can get!!

Answer:

x = 13

Step-by-step explanation:

6x + 14 + 4x - 8 + 2x + 18 = 180 {Angle sum property of tiangle}

6x + 4x + 2x + 14 - 8 +18 = 180 {Combine like terms}

12x + 24 = 180 {Subtract 18 from both sides}

12x = 180 - 24

12x = 156 {Divide both sides by 12}

x = 156/12

x = 13
