What is the slope of the line that contains these point?
(13,11),(14,6),(15,1),(16,-4)
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.
We can find the equation of this line and ascertain that the four points are on a single 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

1. The value of 25 x (8.5) is:
a.
More than 250
b. Less than 250
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.
What is multiplication?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.

The International Average Salary Income Database provides a comparison of average salaries for various professions. The data are gathered from publications and reports obtained directly from government agencies (such as the U.S. Bureau of Labor Statistics) or from the International Labour Organization. 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 _____. 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 _____ .
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
Find the distance from point A to the given line.
Round to nearest tenth
A(2, −1), y = −x + 4
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]
