2(2-x)< or = to -3x-2 *Distribute
4-2x< or = to -3x-2 *Add 3x to both sides
4+x< or = to -2 *Subtract 4 to get x alone
x< or = to -6

Nikitich [7]

Answer:

$\frac{7}{12}$ of the cake

Step-by-step explanation:

add $\frac{1}{8}$ and $\frac{1}{6}$ to see the total amount of cake eaten.

a. find the common denominator: 8 x 3 = 24 and 6 x 4 = 24

b. multiply accordingly to get the correct numerator: $\frac{3}{24}$ + $\frac{4}{24}$

c. add: $\frac{3}{24}$ + $\frac{4}{24}$ = $\frac{7}{24}$

subtract found value from total to find left over cake.

a. 24 - 7 = 14

simplify.

a. $\frac{14}{24}$ = $\frac{7}{12}$

You are left with $\frac{7}{12}$ of the cake.

Rudik [331]

Answer:

a) E(y) = 0.8

b) The average subcharge is $165

Step-by-step explanation:

We are given the following distribution in the question:

y: 0 1 2 3

P(y): 0.50 0.25 0.20 0.05

a) E(y)

$E(y) = \displaystyle\sum y_iP(y_i)\\\\E(y) = 0(0.50)+1(0.25)+2(0.20)+3(0.05)\\E(y) = 0.8$

b) Expected value of subcharge

Subcharge =

$\$110y^2$

Expected value of subcharge =

$=110E(y^2)\\\\=110\displaystyle\sum y_i^2P(y_i)\\\\=110(0^2(0.50)+1^2(0.25)+2^2(0.20)+3^2(0.05))\\=110(1.5)=165$

Thus, the average subcharge is $165
