Answer:

Step-by-step explanation:

You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)

We look at the slope equation as: y2 - y1 divided by x2 and x1.

13 = x1 11= y1 and 14= x2 6=y2

Plug in: 6-11/14-13 and solve

Answer: -5

Hope I made sense :)

Answer:

Slope (m) = -5

Step-by-step explanation:

*If all the given four points are on a straight line then; the slope derived from first two points should be equal to the slope derived from the next to points.

Let's verify this ...

For the first two points:

Slope (m) = change in y ÷ change in x = [tex]\frac{6 - 11}{14 - 13} = \frac{-5}{1} = -5[/tex]

For the next two points:

m = [tex]\frac{-4 - 1}{16 - 15} = -5[/tex]

*Proved ∴ points (13,11) , (14,6) , (15, 1) and (16,-4) are on the same line.

Taking another point (x,y) on the line and point (13,11);

m = [tex]\frac{y - 11}{x - 13} = -5[/tex]

y = -5x + 65 + 11

y = -5x + 76

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The value of 25×8.5 is less than 250. The correct option is B.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The value of 25×8.5 is needed to be calculated in order to know if the product is more than 250 or not. Therefore, the value of the 25×8.5 can be calculated as,

25×8.5

= 25 × (85/10)

= 2125/10

= 212.5

Since the value of the product of 25 and 8.5 is 212.5 which is less than 250. It can be calculated that the number is smaller than 250.

Hence, the value of 25×8.5 is less than 250.

Answer:

a)The average salary, then, for accountants in Canada is $2352

b) The standard deviation of the salary, then, for accountants in Portugal is $388.2

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where:

x is the raw score

μ is the population mean

σ is the population standard deviation.

a) Suppose you are told that an accountant in Canada who makes $2,646.00 has a z-score of +0.50 relative to other accountants in Canada and that the standard deviation of the salary of accountants in Canada is $588.00. The average salary, then, for accountants in Canada is _____.

z = (x-μ)/σ

z = 0.50, x =$2,646.00 μ = ?? σ = $588

Hence,

0.50 = 2,646 - μ/588

0.50 × 588 = 2,646 - μ

294 = 2,646 - μ

μ = 2,646 - 294

μ = $2352

Therefore, the average salary, then, for accountants in Canada is $2352

b) Suppose you are also told that an accountant in Portugal who makes $2, 329.40 has a z-score of +2.00 relative to other accountants in Portugal and that the mean of the salary of accountants in Portugal is $1, 553. The standard deviation of the salary, then, for accountants in Portugal is _____ .

z = (x-μ)/σ

z = 2, x = $2,329.40 μ =$1,553 σ = ?

2 = ($2,329.40 - $1,553)/σ

2σ = $2,329.40 - $1,553

σ = $2,329.40 - $1,553/2

σ = $776.4 /2

σ = $388.2

Therefore, the standard deviation of the salary, then, for accountants in Portugal is $388.2

Answer:

y=-1/10 x - 41/10

Step-by-step explanation:

slope: y2-y1 / x2-x1 = -5-(-4) /  9-(-1) = -1/10

y= -1/10 x +b, substitute (-1,-4) to solve b

-4=-1/10 (-1) +b

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the distance between the line which formed like :

[tex]ax + by + c = 0[/tex]

and the point which is like :

[tex]h = \binom{m}{n} \\ [/tex]

we use following equation :

[tex]d = \frac{ |a(m) + b(n) + c| }{ \sqrt{ {a}^{2} + {b}^{2} } } \\ [/tex]

_________________________________ Step (2)

[tex]y = - x + 4[/tex]

[tex]x + y - 4 = 0[/tex]

So ;

[tex]a = 1[/tex]

[tex]b = 1[/tex]

[tex]c = - 4[/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

A = ( 2 , - 1 )

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

[tex]d = \frac{ | \: 1(2) + 1( - 1) - 4| }{ \sqrt{ {1}^{2} + {1}^{2} } } = \\ [/tex]

[tex]d = \frac{ |2 - 1 - 4| }{ \sqrt{1 + 1} } = \frac{ | - 3| }{ \sqrt{2} } \\ [/tex]

[tex]d = \frac{3}{ \sqrt{2} } \\ [/tex]

And we're done.

Answer:

[tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

Explanation:

Since it is flipped and now extending to negative infinity, we make [tex]x^2[/tex] negative, so it is [tex]-x^2[/tex].

Lastly, there are a few shifts, it is shifted right once and up once.

To shift it right once, you would subtract a 1 from x directly: [tex]-(x - 1)^2[/tex]

To shift it up once, you would add 1 to the entire equation: [tex]-(x - 1)^2 + 1[/tex]

To account for the stretching, it would be: [tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]
