Step-by-step explanation:

I just used my opinion

Answer:elling price (S.P)  =  (100 - m)% ⋅ Original price -----(1)

Here,  

S.P  =  127.46,  m  =  15

Substitute 127.46 for S.P and 15 for m in (1).

127.46  =  (100 - 15)% ⋅ Original price

127.46  =  85% ⋅ Original price

127.46  =  0.85 ⋅ Original price

127.46 / 0.85  =  Original price

149.95  =  Original price

So, the original price is $ 149.95.

Step-by-step explanation:

The original price of product when the product is market down by 15% and the sales price is given so it is $149.95.

Price is down by 15%, so m = 15% or 0.15.

So, Original price = [tex]\frac{Selling price}{( 1 - m)}[/tex]

By putting the value, we get

Original price = [tex]\frac{127.46}{(1 - 0.15)}[/tex]

= [tex]\frac{127.46}{0.85}[/tex]

= $149.95

Hence the original price of of the product was $149.95

Answer:

we conclude that the table ''A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries 16, 17, 19, 20'' represents a non-linear function.

Step-by-step explanation:

The nature of whether a function can be linear or non-linear, we must check how the x and y values of the table change. If the first difference between y-values remains the same (constant first difference), then the table will represent a linear function, otherwise not.

Given the x and y entries of the first table:

x            y

17           20

18           19

19           18

20          17

From the table, it is clear that as x constantly increases by 1 unit, the y-values are also changing constantly by 1 unit. The first difference between y-values remains the same.

i.e. 19-20=-1, 18-19=-1, 17-18=-1

Thus, this table represents a linear function.

Given the x and y entries of the second table:

x            y

17          -16

18          -17

19           -18

20          -19

From the table, it is clear that as x constantly increases by 1 unit, the y-values are also changing constantly by 1 unit. The first difference between y-values remains the same.

i.e. -17-(-16)=-1, -18-(-17)=-1, -19-(-18)=-1

Thus, this table represents a linear function.

Given the x and y entries of the second table:

x            y

17          16

18          17

19           19

20          20

From the table, it is clear that as x constantly increases by 1 unit, but the y-values are not changing constantly. The first difference between y-values does not remain the same.

i.e. 17- 16 = 1, 19 - 17 = 2, 20 - 19 = 1

Thus, this table does not represent a linear function. Hence, it is a non-linear function.

Given the x and y entries of the second table:

x            y

17          -20

18          -19

19           -18

20          -17

From the table, it is clear that as x constantly increases by 1 unit, the y-values are also changing constantly by 1 unit. The first difference between y-values remains the same.

i.e. -19-(-20)=1, -18-(-19)=1, -17-(-18)=1

Thus, this table represents a linear function.

Therefore, we conclude that the table ''A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries 16, 17, 19, 20'' represents a non-linear function.

A coordinate plane.

The point (5, 5) is in Quadrant  

✔ I

.

The point (3, –2) is in Quadrant  

✔ IV

.

The point (–4, –4) is in Quadrant  

✔ III

.

Step-by-step explanation:

give me branliest pls

The point (5, 5) is in Quadrant I, the point (3, –2) is in Quadrant IV, and the point (–4, –4) is in Quadrant III.

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

The area using the ordered double:

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

As we know the coordinate plane is divided into four parts.

The first part is known as I quadrant; in this quadrant both values of x and y are positive.

In the second quadrant II value of x is negative and the value of y is positive.

In the third quadrant III values of x and y are negative.

In the fourth quadrant IV value of x is positive and the value of y is negative.

From the above information:

The point (5, 5) is in Quadrant I

The point (3, –2) is in Quadrant IV

The point (–4, –4) is in Quadrant III

Thus, the point (5, 5) is in Quadrant I, the point (3, –2) is in Quadrant IV, and the point (–4, –4) is in Quadrant III.

Answer: y=1,5x-8

Step-by-step explanation:

At first transform the equation

2x+3y=18

3y= 18-2x

y= 6 - (2/3)x

The linear function has general form, which looks like that:

y=mx+n

perpendicular means that m1*m2=-1

In our case m1= -(2/3) and m2 is unknown

(-2/3)*m2= -1

m2=3/2 so m2=1,5

The line has to go through the point (6,1)

so 1=6*1,5+n

1=9+n

n= -8

so the function looks like that y=1,5x-8

Answer:

The equations are B = -4.5 + 3.25 and B = -4.5 - 3.25

Step-by-step explanation:

Since point A is located at -4.5 and point B is 3.25 units away from A, point B can either be located on the left or on the right of point A.

If point B is located at the right of A, the equation for point B is -4.5 + 3.25.

If point B is located at the left of A, the equation for point B is -4.5 - 3.25.

So, the equations are B = -4.5 + 3.25 and B = -4.5 - 3.25

Answer: The answer is 8 because if you divide each total cost by it’s number of tickets, you will always get 8.

Answer:

5 is the slope

(0,2) is the y intercept

Step-by-step explanation:

The equation y = 5x + 2 appears to be written in the y = mx + b form of a linear equation.

m represents slope and b represents the y value of the y intercept.

Here, m = 5 and b = 2.

This means 5 is the slope and (0,2) is the y intercept.

Step-by-step explanation:

19 kids get an apple each, the 20th kid gets the basket with the apple in it, that’s the answer you want, right?

Well that’s a bogus answer, because how come one kid gets a free basket, and why do you even care that the basket has an apple in it if you don’t get to keep it anyway?

Plus it’s not “all the apples to each one of them” is it? No, it’s one apple each, and different apples are different sizes and degrees of ripeness and maybe some have bruises and it’s just inherently unfair.

Instead, I take 19 apples, and I make applesauce, and I distribute the applesauce using a precision scale so every child gets an exactly equal amount of applesauce, and I keep one apple in the basket, which I keep.

Now, of course it’s not quite “ALL the apples” to the children, but you cannot have your cake and eat it too. I gave an equal amount of apple to each child, and if it was 5% short of all the apples, well, it was, but what of it, that’s the best I can do and still keep one apple in the basket.

Because I am NOT giving one child the basket and having the other nineteen kids complaining about why Johnny got a basket and they didn’t, plus where’s my basket? No, I don’t think so.

Answer:

Give 19 children an orange each = 19 oranges given.

Leave one orange in the basket and give the basket containing that orange to the lucky 20th child.

Answer:

A. The graph of g (x) has the lesser y -intercept

Step-by-step explanation:

I took the test

For f(x) the y-intercept is given by, c = 400 and for g(x) the y-intercept is given by, c' = 360. The correct option is a) and this can be determined by using the slope-intercept form of the line.

Given :

First, determine the function g(x) in order to comment on the graph of g(x). So, according to the given data the expected value, in dollars, of television B is initially $360 and decreases by $90 each year.

Let the total number of years be 'x'. Then the function g(x) is given by:

g(x) = 90x + 360

Now, compare the functions f(x) and g(x) with the slope-intercept form of the line in order to find the y-intercept.

For f(x) the y-intercept is given by, c = 400

For g(x) the y-intercept is given by, c' = 360

Therefore, the correct option is a) The graph of g(x) has the lesser y-intercept.

Explanation:

The given list of values is {6, 11, 13, 8, 15, 9, 11, 5, 9}

It sorts to {5, 6, 8, 9, 9, 11, 11, 13, 15}

The middle most value is the second 9. We have four items below or at the median {5,6,8,9} and four values above the median {11,11,13,15}

The middle item of {5,6,8,9} is (6+8)/2 = 14/2 = 7. This is the value of Q1.

The middle item of {11,11,13,15} is (11+13)/2 = 24/2 = 12. This is Q3.

The min is 5 since it is the smallest of the original list.

The max is 15 because it is the largest of the original list.

Answer:

5.6 pounds

Step-by-step explanation:

13.9 pounds of ice cream are consumed per year by individual.

Ben consumes 6 ounce serving per week.

The amount of ice cream consumed by Ben in a year can be determined by;

since there is an average of 52 weeks in a year, then;

6 ounces x 52 = 312 ounces

But,

1 ounce = 0.0625 pounds

So that,

312 ounces = x pounds

x = 312 x 0.0625

  = 19.5

x = 19.5 pounds

Thus, Ben consumes 19.5 pounds of ice cream per year. He consumes more than the average value per person in a year.

The difference = Amount Ben consumes - National average

                        = 19.5 - 13.9

                        = 5.6 pounds

There's no direct variation

Step-by-step explanation:

Required

Determine if there's a direct variation between the number and its position

I'll start by giving an illustration of how the triangle is represented using stars (*)

*

**

***

****

*****

Represent the line number with y and it's position with x

On line 1:

y = 1, x = 1

On line 2:

y = 2, x = 3

On line 3:

y = 3, x = 6

On line 4:

y = 4, x = 10

On line 5:

y = 5, x = 15

Note that, x is gotten by calculating the accumulated number of stars while y is the line number.

Direct variation is represented by

y = kx

Or

kx = y

Where k is the constant of variation

For line 1:

Substitute 1 for y and 1 for x

k * 1 = 1

k = 1

For line 2:

Substitute 2 for y and 3 for x

k * 3 = 2

Divide through by 3

k = ⅔

Note that the values of k in both computations differ.

This implies that there's no direct variation and there's no need to check further.

Step-by-step explanation:

The probability of having at least one girl out of 3 children can be calculated as;

P(1 girl, 2 boys) or P(2 girls, 1 boy) or P(3 girls)

Since the P(b) = P(g) = 1/2

Then the probability at any point in time is 1/2 * 1/2 * 1/2 = 1/8

So we have ;

1/8 + 1/8 + 1/8 = 3/8 = 0.375

Answer:
