A military commander has been assigned the task of defending an asset from enemy air attack. Commander has two types of air defense missiles; 5 missiles each of type I and type II are available for deployment. Each type I missile costs 7 units for installation and each type II missile costs 8.5 units for installation. The total budget available is 60 units. Each type I missile requires 6 persons for handling whereas each type II requires 2 persons. There are only 32 trained persons to handle the missiles at the site. If the site is not defended the enemy aircrafts are estimated to destroy 95% of the asset value. If one type I missile is deployed on the site, it is expected to save 13% of the asset value. Similarly, deployment of one type II missile is estimated to save 9% of the asset value. In other words, the enemy aircrafts which were earlier capable of destroying 95% of the asset value are able to destroy 82% of the asset value in the presence of one missile of type I and 86% of the asset value in the presence of one missile of type II. Formulate an LP to determine the mix of missiles that provides maximum protection to the asset against an attack of enemy aircrafts aiming simultaneously.

Answers

Step-by-step explanation:

we have A and B

for A,

95-82 = 13

for B,

95-86 = 9

cost of A = 9

cost of B = 8.5

total = 60

for person

A = 6,

B = 2

Total = 32

setting up objective function:

13x + 9y

constraints:

0≤x≤5, 0≤x≤5

7x + 8.5y ≤ 60

6x + 2y ≤ 32 this can be reduced by 2

3x + y≤16

this would take us to a bounded region which has the corner points and the objective values in the attachment i added.

Answers

Answer:

A peak is where the frequency is the highest.

A cluster is a group of bars, meaning the frequency is higher in these intervals.

A peak is a bar that is higher than the other bars around it.

Intervals on a histogram where there are no bars mean the frequency is 0.

If the graph is symmetrical, the data is evenly distributed.

Step-by-step explanation:

The correct statement about histogram is as follows;

A peak is where the frequency is the highest.

A cluster is a group of bars, meaning the frequency is higher in these intervals.

A peak is a bar that is higher than the other bars around it.

Intervals on a histogram where there are no bars mean the frequency is 0.

If the graph is symmetrical, the data is evenly distributed.

We have to determine, which descriptions of a histogram are true?

According to the question,

A histogram meaning can be stated as a graphical representation that condenses a data series into an easy interpretation of numerical data by grouping them into logical ranges of different heights which are also known as bins.

Characteristics of a Histogram are as follows;

A histogram is used to display continuous data in a categorical form.  

In a histogram, there are no gaps between the bars, unlike a bar graph.  

The width of the bins is equal.

A histogram is a type of representation of a data set where bars are used to represent the frequencies.

The area of these bars is said to be proportional to the frequency of the variable.

The peak of a histogram represents the highest value of frequency. Also, the peak is a bar that is higher than the other bars around it.

In a histogram intervals wherein bars cannot be seen would represent the frequency of that would zero.

Also, if the histogram is said to be symmetrical, then the data should be distributed evenly.

A peak is where the frequency is the highest.

A cluster is a group of bars, meaning the frequency is higher in these intervals.

Traditionally, the earth's surface has been modeled as a sphere, but the World Geodetic System of 1984 (WGS-84) uses an ellipsoid as a more accurate model. It places the center of the earth at the origin and the north pole on the positive z-axis. The distance from the center to the poles is 6356.523 km and the distance to a point on the equator is 6378.137 km. Meridians (curves of equal longitude) are traces in planes of the form y=mx.

Required:
a. Find an equation of the earth's surface.
b. What is the shape of these meridians?

Answers

Answer:

a) x²/(6378.137)² + y²/(6378.137)² + z²/(6356.523)² = 1

b) x²/(6378.137)²/(1+m²) + z²/(6356.523)² = 1

Step-by-step explanation:

a)

We know that the general equation of the ellipsoid with center at the origin is  

x²/a² + y²/b² + z²/c² = 1  

Since the north pole is along the z-axis and north pole is at a distance of 6356.523 km from the center, so c = 6356.523  

And the distance between center to a point on the equator is 6378.137 km so we have, a = b = 6378.137  

Thus, the equation of the earth's surface as used by WGS-84 is  

x²/(6378.137)² + y²/(6378.137)² + z²/(6356.523)² = 1

b)

Meridians are traces in planes of the form y=mx, so the equation of paraboloid gives;

x²/(6378.137)² + m²x²/(6378.137)² + z²/(6356.523)² = 1

x²/(6378.137)²/(1+m²) + z²/(6356.523)² = 1

Whitley park is a rectangular park with a perimeter of 70 yards. One side of Whitley park is 18 feet long. What is the area of Whitley park?

Answers

Answer:

174 yards squared

Step-by-step explanation:

If Whitley park is a rectangular park with a perimeter of 70 yards. One side of Whitley park is 18 feet long then 174 yards is the area.

What is Area of Rectangle?

Area of rectangle is length times of breadth.

We know that 18 feet=6 yards.

It is given that One side of Whitley park is 18 feet long, so one side of length is 6 yards.

2(Lenght+breadth)=70

2(L+6)=70

2l+12=70

2l=70-12

2l=58

l=29 yards

Now

Area =Length×breadth

=29×6

= 174 square yards

Hence 174 square yards is the area of Whitley park.

Craig hired 3 high school students to work for his dog walking business. This week, they walked a total of 31 dogs.
Allyson walked 5 less dogs than Brooke.
Carlos walked 3 more dogs than Brooke.
How many dogs did Carlos walk this week?
o Carlos walked 6 dogs.
o Carlos walked 8 dogs.
O Carlos walked 11 dogs.
o Carlos walked 14 dogs.

Answers

Answer:

Carlos walked 14 dogs

Step-by-step explanation:

Let x denotes number of dogs that Carlos walked this week.

As Allyson walked 5 less dogs than Brooke,

Number of dogs that Allyson walked = [tex]x-5[/tex]

As Carlos walked 3 more dogs than Brooke,

Number of dogs that Carlos walked = [tex]x+3[/tex]

Also, total number of dogs walked this week is equal to 31.

So,

[tex]x+x-5+x+3=31\\3x-2=31\\3x=31+2\\3x=33\\x=\frac{33}{3}\\ x=11[/tex]

Therefore, Carlos walked [tex]x+3=11+3=14[/tex] dogs

The administrator of a $200,000 trust fund must adhere to following guidelines.

a. The money may be invested in three different types of securities: a utilities stock paying a 9% dividend, an electronics stock paying a 4% dividend, and a bond paying 5% interest.
b. The amount invested in the stocks cannot be more than half the total amount invested; the amount invested in the utilities stock cannot exceed $40,000; and the amount invested in the bond must be at least $70,000.
c. The total amount need not be fully invested at any one time.

Required:
Setup an LP problem to maximize profit.

Answers

Step-by-step explanation:

let us give all the quantities in the problem variable names.

x= amount in utility stock  

y = amount in electronics stock  

c = amount in bond

“The total amount of $200,000 need not be fully invested at any one time.”

becomes

x + y + c ≤ 200, 000,

Also

“The amount invested in the stocks cannot be more than half the total amount invested”

a + b ≤1/2 (total amount invested),

=1/2(x + y + c).

(x+y-c)/2≤0

“The amount invested in the utility stock cannot exceed $40,000”

a ≤ 40, 000

“The amount invested in the bond must be at least $70,000”

 c ≥ 70, 000

Putting this all together, our linear optimization problem is:

Maximize z = 1.09x + 1.04y + 1.05c

subject to

x+ y+ c ≤ 200, 000

x/2 +y/2 -c/2 ≤ 0

              ≤ 40, 000,

              c ≥ 70, 000

a ≥ 0, b ≥ 0, c ≥ 0.
