Answer:

y = - 2x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line

m = [tex]\frac{-4-2}{4-1}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2

the line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = - 2x + 4 ← equation of line

The solution to the difference 20 4/10 - 3 1/10 is 17 3/10

We have been given two fractions.

20 4/10 and 3 1/10

We need to find the difference 20 4/10 - 3 1/10

First we write improper fraction as a proper fraction.

20 4/10 = 204/10

3 1/10 = 31/10

So, the difference would be,

20 4/10 - 3 1/10

= 204/10 - 31/10

= 173/10

= 17 3/10

Therefore, the solution to the difference 20 4/10 - 3 1/10 is 17 3/10

discount = price at the store - price before tax

discount = $21 - $19.53

discount = 1.47

Con base en el uso de simbología para el acertijo, la edad del conductor es 27 años.

Los acertijos no deben ser entendidos literalmente, sino simbólicamente. Cada elemento representa algo figurativo.

Este acertijo parece incoherente debido a estar incompleto y es preciso añadir un criterio adicional que permita brindar sentido al contenido, este criterio es asumir que un pasajero simboliza un año, que el autobús simboliza al conductor, que el ingreso de un pasajero implica sumar un año a la edad del conductor, que el egreso de un pasajero implica restar un año a la edad del conductor y que la población resultante dentro del autobús es la edad del conductor.

En consecuencia, efectuamos la siguiente operación para determinar la edad del conductor:

The equation of the line passing through (-5, 1) and is parallel to y = -2/5x -5 in standard form is 5y + 2x = -5

The equation of a line can be represented in standard form or slope intercept form as follows;

Slope intercept form,

y = mx + b

where

Line are parallel when they have the same slope.

Therefore, the slope of the equation has a slope of - 2 / 5 x.

The line passes through (-5, 1).

Hence, let's find y-intercept.

y = - 2 / 5 x + b

1 = - 2 / 5 (-5) + b

1  - 2 = b

b = -1

Therefore, y = -2 / 5x - 1.

The equation in standard form should be in the form Ax + By = C.

Hence,

y + 2 / 5 x  = -1

The inequality describing oil and tyre change within 180 minutes is 3x + 4y > 60.

Taking each information seperately followed by summing them for a complete equation.

1 oil change taken amount of time = 9 minutes

So, x oil change will take amount of time = 9x

Similarly, y number of tire changes will take amount of time = 12y

Adding these values to form the equation -

Number of oil and tyre changes in less than 180 minutes

Keep the value of each and symbol for 'less than'

2B times as many gallons does pool A hold than pool B.

What is gallons?

The gallon is a volumetric unit that is used in both imperial and American customary measurements.

The imperial gallon (imp gal), which is equal to 4.54609 liters and was once used in various Caribbean nations as well as the United Kingdom, Ireland, Canada, Australia, and Australia.

Given:

Swimming pool A has 2^15 gallons of water.

Swimming pool B has 2^13 gallons of water.

We have to find the number of times pool A hold than pool B.

It is obvious that Swimming Pool A holds more water than Swimming Pool B.

Consequently, we must determine how many times as many gallons Pool A holds as Pool B:

2^15 > 2^13.

Therefore,

A = 2^15,  B = 2^15

[tex]A = (\frac{2^1^5}{2^1^3}) B = 2B\\ A = 2B[/tex]

The F-test is used in regression analysis to test the hypothesis that all model parameters are zero. It is also used in statistical analysis when comparing statistical models.

Statistical models that have been fitted using the same underlying factors and data set to determine the model with the best fit. That is:

H₀ : B₁ = B₂ = .............  = Bₓ =0

H₁: Bₙ ≠ 0 for at least one j.

The F-test was developed by Ronald A. Fisher (hence F-test) and is a measure of the ratio of variances. The F-statistic is defined as:

F = [tex]\frac{explained variables}{unexplained variables}[/tex]

A general rule of thumb that is often used in regression analysis is that if  

F > 2.5then we can reject the null hypothesis. We would conclude that there is a least one parameter value that is nonzero.

The F-distribution is generally a skewed distribution and also related to a chi-squared distribution. The f distribution is the ratio of X1 random chi-square variable with degrees of freedom ϑ1 and X2 random chi-square variable with degrees of freedom ϑ2.

From the information, when Ben sat outside his school in Cambridge and made a note of the colour of the first 100 cars that passed, he found out that 27 of them were red.

Based on the above, the ratio of red cars to total cars is 27:100.

Therefore, if thee are 35 million cars, the red cars will be:

= Ratio of red cars × Total cars

= 27/100 × 3500000

Answer:

Step-by-step explanation:

First, add up the total and find a number divisible for your total which is 105. The next step will be to divide by a number that can go into it easily, like 3 for example. then you would get 35. Since we want the most groups try a number *2 of 3 and that will be 6. After you divide you'll get 17.5 . and since there isn't .5 of a person you go to the lowest number ( not rounding ) and that'll be 17 since 105 divide another multiple of 3 would get you 11.66 repeated.

Using the concepts of weighting, we got that demographic groups helps in fixing  difference between the levels of different people if there are many or too few people in the sample from that group, compared to the population as a whole.

Demographic segmentation examples actually explain how researchers divide a market into the smaller groups according to age, gender, family income, race and ethnicity, qualification, marital status, nature of the  employment, etc.  

It is an extremely tedious task to the accommodate customers belonging to different demographics and develop the exhaustive marketing plan. Demographic examples ease creating the strategy for a marketer. Thus, they are one of  most commonly implemented marketing segmentation methods compared to the other techniques such as geographic segmentation, behavioral segmentation, or the psychographic segmentation.

Hence, certain demographic groups might end up being under or over-represented means that  there are too many or too few people in the sample from that group, compared to the population as a whole, in that case weighting can therefore potentially helps in fixing the difference in the levels of different people.

The equation that represents the proportional relationship is y = 14x.

We are given a table. The table contains the values for "x" and "y". The first row contains the data for the variable "x". The values of "x" are 1, 2, and 3. The second row contains the data for the variable "y". The corresponding values of "y" are 14, 28, and 42. We know that the table shows a proportional relationship between the values of "x" and "y". Let the constant of proportionality be represented by the variable "k".

y ∝ x

y = k*x

k = y/x

The value of k must be the same for each corresponding pair of values of "x" and "y".

k = 14/1 = 28/2 = 42/3 = 14
