First Answer: y=3-4x

Step 1: Property of Inequality!

4x-y=3 = (4x-4x) - y=(3-4x)

Step 2: Solve!

4x-4x=0 which leaves us with y=3-4x

Second Answer: y=6/10

Each of 150 volunteers was assigned at random to one of five rooms where they were asked to taste and rate a glass of wine. In one of the rooms, no music was playing and a different style of music was playing in each of the other four rooms. The researchers concluded that cabernet sauvignon is perceived as being richer and more robust when bold music is played than when no music is heard.

Required:
a. Is the study described an observational study or an experiment?
b. Can a case be made for the researcher's conclusion that the music played was the cause for the higher rating? Explain.

Answers

Answer:

a. Experiment

b. yes

Step-by-step explanation:

The study being conducted in this scenario is an experiment because different groups are being created and both an independant variable and dependant variable are being introduced. This means that there is researcher involvement and therefore makes this an experiment and not an observational study.

Yes, a case can be made for such a claim. This is because the music being played is the dependent variable in each of the groups. Meaning that the only difference in each of the groups was the music. Therefore, any differences in the data gathered can be connected to the music.

DF = 20.4

Step-by-step explanation:

The figure given is a kite.

A kite has two set of opposite sides that are congruent. And the diagonals bisect each other. Thus,

∆DEH is congruent to ∆FEH, therefore, DH = HF

Use pythagorean theorem to find DH:

DH² = DE² - EH²

DH² = 15² - 11²

DH² = 104

DH = √104

DH = 10.2 (nearest tenth)

DF = 2(DH)

DF = 2(10.2)

DF = 20.4

The komodo dragon are the biggest and heaviest lizards on earth. Full grown adults can reach 2.8 meters long and weigh more than 300 pounds! What is the length of the komodo dragon in centimeters? A) 28 cm B) 280 cm C) 2800 D) 28000

Answers

Answer:

280 cm

Step-by-step Explanation

The Komodo dragon 2.8 meters long and weigh more than 300 pounds, the length of the Komodo dragon in centimeters is, 280. So Option B is correct

What are Units ?

To measure and compare various things we use one term which is known as a unit. When all of the measuring units are the same, comparison is simple. Depending on their intended usage, different units can be categorized.

For example, for  length measurement we use units like:- meter, centimeter, inch, miles.

Given that,

The Komodo dragon are the biggest and heaviest lizards on earth

Full grown adults can reach 2.8 meters long and weigh more than 300 pounds

The length of the Komodo dragon in centimeters = ?

Assume, Komodo is fully grown

So, the length of the Komodo = 2.8 meter

It is known that,

1 meter = 100 centimeter

Now,

2,8 meter = 2.8 × 100 centimeter

                =  280 centimeter

Therefore, the length in centimeter is 280

1. Is a triangle with side lengths 6, 4, 3 a right triangle? Why or why
not?

Answers

Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 6 , then 6² = 36

4² + 3² = 16 + 9 = 25

Since 4² + 3² ≠ 6² then triangle is not right.

C. y= x(x-6)(x + 1)(x + 3)
D. y=(x-3)(x - 1)(x + 6)

Answers

Answer:

C

Step-by-step explanation:

The function is y=x(x-6)(x+3)(x+1). Therefore, option C is the correct answer.

Given that, a function with zeros at -3,-1, 0, and 6.

What are zeros of a function?

The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

Now, x=-3⇒x+3, x=-1⇒x+1, x=0 and x=6⇒x-6.

The function is y=x(x-6)(x+3)(x+1).

The function is y=x(x-6)(x+3)(x+1). Therefore, option C is the correct answer.

a. Draw a rectangle with an
area of 39 squares, and
perimeter of 32 units.
a

Answers

Answer:

It has side lengths of 3 and 13

Step-by-step explanation:

If it has an area of 39, then let the sides be x and y: thus we get the two relationships:

xy=39

2(x+y)=32

From the second equation, you get x+y=16. Now, rearrange to get y=16-x. You can now plug this into the first equation:

x(16-x)=39 -> 16x-x^2=39 -> x^2-16x+39=0 -> (x-3)(x-13)=0

This implies that x=3, or x=13, which further implies that the side lengths must be 3 and 13.

(x = 0) + (x = 1) + (x = 2) + (x = 3) + (x = 4) + (x = 5) + (x = 6)

(11.67 + 20.00 + 21.67 + 23.33 + 10.00 + 5.00 + 5.00) = 96.67% = 0.967 (3 decimal places)

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? 6 1 -Xt 3 1 = } 2x+5 o 2 o 3 6 O 12​

Answers

Correct question is;

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? 6 – ¾x + ⅓ = ½x + 5

Answer:

12

Step-by-step explanation:

We are given the equation as;

6 – ¾x + ⅓ = ½x + 5

In order to find out the number that each term can be multiplied by, we will need to express each denominator as a product of its prime factors to find the lowest common factor.

Thus;

Factors of 4 = 1 × 2 × 2

Factors of 3 = 1 × 3

Factors of 2 = 1 × 2

Thus, LCF = 1 × 2 × 2 × 3 = 12

While the histogram is not perfectly symmetric (there is mild right skewness), it is close enough to being symmetric and mound-shaped to justify using the 68-95-99.7 rule. Suppose the distribution of calories in a Chipotle meal can be considered symmetric and mound-shaped with mean 1060 calories and standard deviation 291 calories.

Required:
a. What is the approximate percentage of the Chipotle meals that have more than 469 calories?
b. What is the approximate percentage of Chipotle meals with calorie amounts between 1372 calories and 1673 calories?
c. If a particular meal's calorie amount is equal to the 16th percentile of Chipotle meal calorie amounts, how many calories are in the meal?

Answers

Answer:

97.9% ; 12.4% ; 771

Step-by-step explanation:

The approximate percentage who have more Than 469 calories :

P(x > 469)

Mean, m = 1060

Standard deviation, s = 291

Z = (x - mean) / standard deviation

Z = (469 - 1060) / 291

Z = −2.030927

P(Z > - 2.031) = 1 - P(Z < - 2.031)

P(Z > - 2.031) = 1 - 0.0211

P(Z > - 2.031) = 0.9788 = 97.9%

b. What is the approximate percentage of Chipotle meals with calorie amounts between 1372 calories and 1673 calories?

[(1673 - 1060) / 291] - [(1372 - 1060) / 291]

P(Z <2.106) - P(Z < 1.072)

0.9824 - 0.85814

= 0.12426 = 12.4%

c. If a particular meal's calorie amount is equal to the 16th percentile of Chipotle meal calorie amounts, how many calories are in the meal

The Zscore at 16 percentile = -0.994

Zscore = (score - mean) / standard deviation

-0.994 * 291 = score - 1060

−289.254 = score - 1060

Score = −289.254 + 1060

Score = 770.746

Approximately 771
