Answer: 13.5 Okay! Here's the method count the legs of the right triangle

The formula we'll use will be

A^2 + B^2 = C^2

In this case we're counting by twos

The base is 11 so we times it by itself =110

The leg is 8.5 so we going to times itself to make 72.25 add those together so 110+ 72.25 = 182.25 then we \|-----

182.25

Then you have got ur answer of 13.5

alexgriva [62]
Assuming a normal distribution  we find the standardized z scores for  a:-

z1 = (80 - 180)  / 25  =  = -100/25  = -4
z2 =  (280-180) / 25  =  4
Required P( -4 < z < 4)  from the tables is  >99.9%

b
z1 = 130-180 / 25 =  -2
z2 =  230-180 / 25  = 2

from tables probability is 2* 0.4773  =  95.46 %

Shopping at clothing world, jenna buys her children four shirts and three pairs of pants for 124.25. She returns the next day an
Aleksandr-060686 [28]

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

Step-by-step explanation:

Let,

Cost of one shirt = x

Cost of pair of jeans = y

According to given statement;

4x+3y=124.25    Eqn 1

3x+5y=161.25     Eqn 2

Multiplying Eqn 1 by 3

3(4x+3y=124.25)\\12x+9y=372.75\ \ \ Eqn\ 3

Multiplying Eqn 2 by 4

4(3x+5y=161.25)\\12x+20y=645\ \ \ Eqn\ 4

Subtracting Eqn 3 from Eqn 4

(12x+20y)-(12x+9y)=645-372.75\\12x+20y-12x-9y=272.25\\11y=272.25

Dividing both sides by 11

\frac{11y}{11}=\frac{272.25}{11}\\y=24.75

Putting 24.75 in Eqn 1

4x+3(24.75)=124.25\\4x+74.25=124.25\\4x=124.25-74.25\\4x=50

Dividing both sides by 4

\frac{4x}{4}=\frac{50}{4}\\x=12.50

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

A portfolio has a E[r] of 12% and a std deviation of 18%. T-Bills return 7%. What is the maximum level of risk aversion (A) for
solniwko [45]
<h2>The required "option D) 3.09" is correct.</h2>

Step-by-step explanation:

Given,

A portfolio has a E[r] = 12 %, and

A standard deviation (\sigma) = 18 %

We know that,

Specify utility by U = E(r) – 0.5A\sigma^2

U = 0.12– 0.5(A) × 0.18^2

= 0.12 - 0.5  ×  A × 0.0162

In order for the risky portfolio to be preferred to bills,

The following condition must have:

0.12 – 0.0162A > 0.07

⇒ A < \dfrac{0.05}{0.0162} = 3.09

A must be less than 3.09 for the risky portfolio to be preferred to bills.

Thus, the required "option D) 3.09" is correct.
