Hi,

To solve if it is a rectangle you would use the formula:

Area= Length x width or A=lw

A= 8.5 x 14

A= 119 inches²

Alright, here's one for Algebra:

Wewaii [24]

Let x= number rows
Then x + 5 = number of seats per row

x(x+5) = 126
X^2 + 5x = 126
x^2 + 5x -126 = 0; now factor or use quadratic:
(x+14)(x-9) = 0; so the answers are either -14, or 9, and since -14 is not possible in this case because you can't have a negative number of rows, the answer is 9 rows.

Check work: number of rows = 9, number of seats per row = 9+ 5= 14, and 9 x 14 = 126

The cow produces 5 liters a day.
You want to find how much it will produce a day if the cow produces 200% more milk. So, you use the equation p*(1+x/100)
<span>5×(1+200/100)=15</span>

Consider a simple example of moral hazard. Suppose that Woodrow goes into a casino to make one bet a day. The casino is very bas

Answer:

The expected value of the safe bet equal $0

Step-by-step explanation:

$S=\left\{s_1,s_2,...,s_n\right\}$

is a finite numeric sample space and

$P(X=s_k)=p_k$ for k=1, 2,..., n

is its probability distribution, then the expected value of the distribution is defined as

$E(X)=s_1P(X=s_1)+s_2P(X=s_2)+...+s_nP(X=s_n)X)$

What is the expected value of the safe bet?

In the safe bet we have only two possible outcomes: head or tail. Woodrow wins $100 with head and “wins” $-100 with tail So the sample space of incomes in one bet is

S = {100,-100}

Since the coin is supposed to be fair,

P(X=100)=0.5

P(X=-100)=0.5

and the expected value is

E(X) = 100*0.5 - 100*0.5 = 0
