Answers

Answer:

Size - continuous

Screen type - Qualitative

Number of channels - discrete

Step-by-step explanation:

____size ____screen type ____no of channels

_A __50 ____ projection ________298

_B __ 51 ____ projection ________ 117

_C __ 58 ____ Plasma __________423

_ D __43 ____ projection ________269

_ E __ 44 ____ Plasma __________ 289

The individual being studied are the characteristics of high definition televisions

Size of television is a continuous variable as the inches of televisions aren't finite and may not necessarily be whole numbers.

Screen type is a Qualitative variable also called categorical as it places different Television sets into distinct category based on the nature of the screen material.

Number of channela is discrete as it defines a finite number stations available. Available stations will always be whole numbers without decimals.

Does the following depict a translation,rotation, or reflection?

Answers

Answer:

This would represent a translation.

Step-by-step explanation:

It wouldn't be a reflection since both images would be reflected on the same x-axis or y-axis. And it wouldn't be rotation because the form of the shape would have been different in a way that instead of being on it's side it would have been upright. So that leaves us with translation.

Answers

Answer: Exact Form: d= 2√58

Decimal Form: 15.23154621...

Step-by-step explanation:

Distance formula: d=√(x2-x1)^2 + (y2-y1)^2

d=√(5- -9)^2 + (-4 - 2)^2

Exact Form: d= 2√58

Decimal Form: 15.23154621...

The distance between two points (-9,2) and (5,-4) is 15.23 units.

What is the distance between two points?

The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.

The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².

We have to determine the distance between (-9,2) and (5,-4)

As per the question, substitute the known values in the formula,

d = √ {(-9 – 5)² + (2 – (-4))²}

d = √ {(-14)² + (6)²}

d = √ {196 + 36}

d = √232

d ≈ 15.23

Thus, the distance between the given two points is 15.23 units.

The total number of calories consumed by Ethan when eating French fries varies directly with the number of French fries that Ethan eats. Ethan eats 16 French fries and consumes 224 calories. How many French fries does Ethan eat if he consumes 406 calories?

Answers

Answer:

29 French fries

Step-by-step explanation:

Total number of calories consumed by Ethan when eating French fries varies directly as the number of French fries that Ethan eats

The first step is to calculate the constant k

No of calories= k × no of French fries

k = No of calories/No of French fries

k = 224/16

k = 14

Therefore the number of French fries eaten by Ethan if he consumes 406 calories can be calculated as follows

No of French fries= No of calories/k

= 406/14

= 29

Hence Ethan eats 29 French fries if he consumes 406 calories

Your phone plan charges you an initial fee, and then a certain amount depending on the amount of data you use. They send you periodic updates of your usage and your current bill cost. After using 3 GB of data, you owe $30. After 5 GB of data, you owe $40. What is the cost per GB of data?

Answers

Answer:

$5

Step-by-step explanation:

Let

x = initial fee

y = fees depending on the amount of data he use

After using 3 GB of data , he owes $30.

After using 5 GB of data , he owes $40.

The equations are

x + 3y = 30 (1)

x + 5y = 40 (2)

Subtract (1) from (2) to eliminate x

5y - 3y = 40 - 30

2y = 10

Divide both sides by 2

y = 10/2

y = $5

Substitute y = 5 into (1)

x + 3y = 30

x + 3(5) = 30

x + 15 = 30

x = 30 - 15

x = $15

Cost per GB of data = $5

We have to find the value of z + 12w.....?

Since we have to find the value of the polynomials for the given values of variables. Plug the given values of z and w in the above question:

➝ z + 12w

➝ 8 + 12(4)

Making Equivalent Fractions :

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

Answers

Answer: 10.00 km/l

Step-by-step explanation:

From the question, we are informed that a car travelled 566.48 kilometres on 63.59 litres of gasoline. Based on this information, the number of kilometres per litre the car travelled will be:

= 566.48km/63.59litres

= 8.9kilometres/litres.

This is closest to 10.00 km/l
