Amy invested in three companies: 1400 dollars for Apple, 1900 dollars for Google and 1700 dollars for Starbucks. Over the course of one year, she found that Apple went down 4 percent, Google went up 5 percent and Starbucks went up 3 percent. What is the average change in her portfolio?

Answers

Answer 1

Loss in apple [tex]=1400\times \dfrac{4}{100}= 56[/tex]

Present value = 1400 - 56 = $1344 .

Loss in google [tex]= 1900\times \dfrac{5}{100}=95[/tex]

Present value = 1900 + 95 = $1995 .

Loss in Starbucks [tex]=1700\times \dfrac{3}{100}=51[/tex]

Present value = 1700 + 51 = $1751 .

Total investment , T = 1400 + 1900 + 1700 = $5000 .

Gain , G = 56 + 95 + 51 = $202 .

% increase [tex]=\dfrac{202}{5000}\times 100 = 4.04 \%[/tex]

Hence , this is the required solution .

Which of the following sets of numbers does square root of 49?

Answers

Answer:

7

Step-by-step explanation:

Natural numbers , Real numbers ,Whole numbers ,Integers , Rational numbers

sqrt(49) = 7

So this number is in the set of...

Natural numbersWhole numbersIntegersRational numbersReal numbers

The set of natural numbers is {1,2,3,...} and the set of whole numbers is {0,1,2,3,...}. Basically we just added in 0. Integers will be similar but we now have negative values too {..., -3, -2, -1, 0, 1, 2, 3, ...}

Rational numbers are anything of the form a/b with a,b being integers. In other words, if we can write the number as a fraction of two integers, then we have a rational number. In the case of 7, we have 7 = 7/1, so it is rational.

The set of real numbers includes every number type you have learned of so far (natural, whole, integer, etc). If you haven't learned about imaginary or complex numbers yet, then every number your teacher will go over is a real number.

Solve 5x - 4< 2x + 5. Enter your answer as an inequality.

Answers

Answer:

x < 3

Step-by-step explanation:

5x - 4 < 2x + 5

Subtract 2x from both sides

5x - 4 - 2x < 2x + 5 - 2x

5x - 2x - 4 < 2x - 2x + 5

3x - 4 < 0 + 5

3x - 4 < 5

Add 4 to both sides

3x - 4 + 4 < 5 + 4

3x < 9

Divide both sides by 3

3x/3 < 9/3

surveyed, he asked them for their age and interviewed them about their musical preferences.
Once he was done, he analyzed his results and found that younger people prefer pop and hip-hop music
while older people prefer jazz and classical music.
What type of statistical study did Vishal use?
Choose 1 answer:
Sample study
Experiment
Observational study

Answers

Answer:

Sample study

Step-by-step explanation:

Sample study is a type of statistical study that is done by taking samples from respondents for any research purpose.

In this type of statistical study, a group of people are selected and asked some questions or data collected.

The type of statistical study that Vishal used was Sample Study because he collected data from a group of respondents to arrive at a hypothesis.

Vishal study of relationship between people's age & musical preferences is 'Observational Statistical Study'

Given : Vishal approached all people in city, enquired willing ones about age & musical preferences, & analysed conclusion thereafter.

Vishal used Observational Statistical Study, as :

Sample study denotes - component step of choosing few representatives ie sample units from all ie population units. It is a part of all statistical studies, & not a type of study in itself. Observational Study - involves studying the sample units in natural uncontrolled or un intervened setup , based on the variable/ traits or relationship study needed by nature of study. Experimental Study - involves studying & analysing variables traits or relationships, in manipulated, controlled or artificially treated experiment setup.

Vishal collects sample from his city & studies them as it is, without any artificial intervention. Hence this natural enquiry based study of age & musical preferences is Observational Study

Suppose LCM(a,b) = 20160, a=60. Find the smallest possible value of b.

Answers

Answer:

see below

Step-by-step explanation:

given:

LCM(a,b) = 20160, a=60

find:

smallest possible value of b

solution;

60, b = 20,160

b = 20,160 / 60

b = 336

60 x 336 = 20,160

= 2⁶ x 3² x 5 x 7

= (2² x 3 x 5) x (2⁴ x 3 x 7)

= (60) x (336)

LCM(60,336) = 1680

consider the 2² x 3 to get the prime number:

= 336 x 12

= 4032

therefore,

LCM(60,4032) = 20160

The smallest possible value of b is 336.

What is Prime Factorization?

Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.

We have been given that

LCM(a,b) = 20160 and  a = 60

We have to determine the smallest possible value of b

Since the product of two numbers equals the product of their HCF and LCM.

⇒ 60 × b = 20,160

⇒ b = 20,160 / 60

⇒ b = 336

⇒ 60 × 336 = 20,160

We need to write 20160 as the product of its prime factors, which is 20160.

⇒ 2⁶ × 3² × 5 × 7

⇒ (2² × 3 × 5) x (2⁴ × 3 × 7)

⇒ (60) × (336)

⇒ LCM(60,336) = 1680

Therefore, the smallest possible value of b is 336.

For what value of the variable will the expression 2b−3 be equal to the following: −11

Answers

To find the value b that makes the expression equal to -11, set up an equation: 2b – 3 = -11. Add 3 to both sides:
2b -3 +3 = -11 +3. Now you’re left with 2b = -8 .
Now divide 2 to both sides: 2/2 b = -8 / 2.
b = -4. Hope that helps

Find the general solution of the homogeneous system below. Give your answer as a vector.
x1 + 2x2 - 3x3 = 0
4x1 + 7x2 - 9x3 = 0
-x1 - 3x2 + 6x3 = 0

Answers

Answer:

Step-by-step explanation:

Given the system of homogeneous equations

x1 + 2x2 - 3x3 = 0  ................. 1

4x1 + 7x2 - 9x3 = 0 ................... 2

-x1 - 3x2 + 6x3 = 0..................... 3

First we will reduce the equation to two equations and two unknowns;

add equation 1 and 3;

2x2-3x2 +(-3x3+6x3) = 0

-x2 + 3x3 = 0

x2 = 3x3 .......... 4

Multiply equation 3 by 4 and add to equation 2;

equation 3 * 4 will give;

-4x1 - 12x2 + 24x3 = 0..................... 5

add equation 5 to equation 2;

7x2-12x2-9x3+24x3 = 0

-5x2 - 15x3 = 0 .......... 6

5x2 = 15x3

x2 = 3x3

Let x2 = k

From equation 4;

k = 3x3

x3 = k/3

substitute x2 = k and x3 = k/3 into equation 1 to get x1 in terms of k

From 1, x1 + 2x2 - 3x3 = 0

x1+2k-3(k/3) = 0

x1 +2k-k = 0

x1 +k = 0

x1 = -k

Writing the answer in vector form will give (x1. x2. x3) = (-k, k, k/3)

k(-1, 1, 1/3)

Hence the answer to the system of equation in vector form is k(-1, 1, 1/3) where k is any constant.

Include evidence from the article to support your answer. Do you think this author has an agenda? If so, what is it? If not, what is the purpose of her article? Does she achieve her purpose? Whats for Lunch?Marcia Amidon LustedZachary Maxwell was tired of trying to explain to his parents why he wanted to bring lunch to school instead of eating hot lunch. They couldnt understand why he didnt want to eat the gourmet food described on the schools online menu, which sounded both nutritious and interesting. Zachary just couldnt convince them that the food wasnt as great as it sounded. So in the fall of 2011, he began sneaking a small video camera into the cafeteria at his school, to show his parents what the lunches were really like. Six months and 75 school lunches later, Zachary made a documentary film about his lunch called Yuck: A 4th Graders Short Documentary About School Lunch.Truth in Advertising?"The citys Department of Education says that its committed to providing delicious and nutritious meals through their food service program. But the lunch being served at my school was nothing like what they were advertising on their web site," Zachary, now 11, says in the documentarys trailer. "I told [my parents] thats not what they were actually serving me," he said. "But I dont think they believed me." For example, an "oven-baked pizza bagel with tricolor salad" was really nothing more than a slice of pizza and a wisp of lettuce. Sometimes there was no connection between the menu and what Zachary actually got. "Cheesy lasagna rolls with tomato basil sauce, roasted spinach with garlic and herbs" was, in reality, just a plastic-wrapped grilled cheese sandwich, all alone on a foam plate."When I came back home and showed them the footage, they were like, ugh!" Zachary said. His dad, an amateur filmmaker, started helping Zachary transform his video footage into a film. It won several awards, and Zachary also made appearances on television shows like Good Morning America.Not Perfect, But BetterLets face it: many times school lunches just arent going to taste as good as they sound. Students also complain that with lunches that follow the new school lunch guidelines, there just isnt enough food. Smaller portions, more fruits and veggies, and fewer calories leave some kids, especially teenagers, still hungry after eating their lunch. A group of students in Kansas even wrote a music video called "We Are Hungry," where they sing about their stomachs growling after lunch and how theyre collapsing on the sports field because they havent eaten enough.However, the new federal lunch guidelines do mandate meals that are better for students, with less sodium, more whole grains, fewer calories, and more fruits and vegetables, as well as skim or 1 percent milk. These are a definite improvement over school lunches of not that many years ago, which once stuck with fare like burgers, French fries, and chicken nuggets. Some schools even allowed fast food outlets like McDonalds and Pizza Hut to operate mini-restaurants in their cafeterias, or supply their products for students. Many schools have also reconsidered vending machines filled with sugary sodas, candy, and chips, replacing them with water and healthy snacks.The Lunch ForecastThe new school lunches are designed to help students eat better, and combat health problems like obesity in kids. Ideally, a healthy school lunch should also taste good ... or at least as good as the description on the menu. It should also keep students from taking a trip to the vending machine or a nearby convenience store as soon as lunch is over, because theyre still hungry. But will the lunches served in your cafeteria ever taste as good as a fast food burger or a gourmet meal cooked at home? You be the judge.
