Step-by-step explanation:
Let’s have two points (5,10) and (15,20)
1. Let’s find the slope of these two points
Mathematically, the slope can be calculated using the formula;
m = (y2-y1)/(x1-x2)
So m = (20-10)/(5-15) = 10/-10 = -1
The error here is the formula used in calculating the slope
The formula should be;
m = (y2-y1)/(x2-x1) and not x1-x2
2. To calculate the slope correctly, we have;
m = (y2-y1)/(x2-x1)
So the slope will be;
m = (20-10)/(15-5) = 10/10 = 1
In the point slope form, the equation can be represented as;
y-y1 = m(x-x1)
Let’s use the point (5,10)
y- 10 = 1(x-5)
The above is the point slope form
using one of the points and the correct slope of the line

Twenty seven percent of the employees in a company have managerial positions, and 5 percent of the employees in the company have MBA degrees. Also, 59 percent of the managers have MBA degrees. Using the probability formulas, find the proportion of employees who either have MBAs or are managers.
Answer:
Step-by-step explanation:
Given that :
27% employees managerial position
5% Employee have MBA
59% of managers have MBA
Proportion of employees who either have MBA or are managers :
P(either manager or MBA) = P(Manager U MBA)
= P(manager) + P(MBA) - [P(manager n MBA) * P(Manger)]
P(manager ) = 0.27
P(MBA) = 0.05
P(manager n MBA) * P(Manger) = 0.59 * 0.27 = 0.1593
P(manager) + P(MBA) - [P(manager n MBA) * P(Manger)]
= 0.27 + 0.05 - 0.1593
= 0.1607

In ΔDEF, \overline{DF} DF is extended through point F to point G, \text{m}\angle FDE = (2x+4)^{\circ}m∠FDE=(2x+4) ∘ , \text{m}\angle DEF = (3x+3)^{\circ}m∠DEF=(3x+3) ∘ , and \text{m}\angle EFG = (7x-5)^{\circ}m∠EFG=(7x−5) ∘ . Find \text{m}\angle FDE.M∠FDE.
Answer:
18°Step-by-step explanation:
See the diagram attached:
In a triangle, the sum of interior angles is equal to the exterior angle.
According the diagram, the sum of interior angles is given as:
Sum of interior = <FDE+<DEF
Given
<FDE = 2x+4
<DEF = 3x+5
Sum of interior = 2x+4+3x+5
Sum of interior = 5x+9
Exterior angle = <EFG = 7x-5
Equate the interior to the exterior and calculate the value of x:
5x+9 = 7x-5
Collect like terms
5x-7x = -5-9
-2x = -14
x = -14/-2
x = 7
Next is to get <FDE:
<FDE = 2x+4
<FDE = 2(7)+4
<FDE = 14+4
<FDE = 18°
Hence the measure of <FDE is 18°

What percentage of students at your school prefers ice cream over cake?
Not really sure about what kind of an answer you want here...
I think you should count up every student's favorite choice and create a table. Then, let's just say there are a total of 30 students. 25 prefer ice cream over cake. The fraction of the students who prefer ice cream over cake is [tex]\frac{25}{30} = \frac{5}{6}[/tex].
Using a calculator, divide 5/6 to find the decimal percentage. 5/6 = 0.8333 (continuing on forever). Fractions are always more accurate, so when finding the percentage it won't be fully accurate since the 3s continue forever. This will be with a lot of numbers like 1/3 or even 2/3.
Now, shift the decimal two spaces forward, making 83.33
83.33% is your answer to this example problem I have created.

Manu gave the cashier $ 80 to pay for 5 pairs of doggy collars. The cashier gave him $20.50 in change. Each doggy collar cost the same amount. What is the cost in dollars and cents for each doggy collar?
Answer:
I think it is $11.90.
Step-by-step explanation:
All I did was this:
80 - 20.50 = 59.50.
59.50 / 5 = 11.90.

find the slope of the line
Answer:
[tex]m=2[/tex]
General Formulas and Concepts:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Step-by-step explanation:
Step 1: Define points
(-2, 2)
(0, 6)
Step 2: Find slope
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{6-2}{0-(-2)}[/tex]
[tex]m=\frac{4}{0+2}[/tex]
[tex]m=\frac{4}{2}[/tex]
[tex]m=2[/tex]

Which of the following is the best description of a positive association between two variables?
A
The values will create a line when graphed on a scatterplot.
B
The values will create a line
with positive slope when graphed on a scatterplot.
с
As the value of one of the variables increases, the value of the other variable tends to decrease.
D
As the value of one of the variables increases, the value of the other variable tends to increase.
E
All values of both variables are positive.
The statement "if the value of one variable is increased so the value of the other variable is also increased" is correct.
The positive association between two variables refers to that if there is an increment in one variable so then the other variable should also increase.
And, if the one variable is decreasing, so the other variable is also decreasing. That means there is a direct relationship between these two variables.
So, the following statements do not consider the positive association:
The value does not develop a line in the case when it should be graphed on a scatterplot.The value does not develop a line in the case having a positive slope that is graphed on a scatterplot.There is no indirect relation between the two variables. The values of both variables can't be positive.Therefore we can conclude The statement "if the value of one variable is increased so the value of the other variable is also increased" is correct.

Step-by-step explanation:
Some investments in the stock market have earned 10% annually. The total value of the
investment, A. at this rate can be found using A = P(1.10)^n. where P is the initial value of the
investment, and n is the number of years the money is invested. If $1.000 is invested in the
stock market at this annual rate of return, what is the expected total value after 18 years?
$4,054.47
$5,559.92
$18,700.00
$19,800.00
Answer:
$5,559.92.
Step-by-step explanation:
NB: Please note that the $1.000 is not correct. If we use it the none of the option will not be correct which means that the value was a mistake. Obviously, It should have been a ''comma'' instead of a ''full stop''. So, it should be ''...$1,000 is invested...'' and not ''...$1.000 is invested...''
So, without mincing words let us dive right into the solution of this particular problem/question.
We have that the '' total value of the investment, A. at this rate can be found using A = P(1.10)^n. where P is the initial value of the investment, and n is the number of years the money is invested.''
Using the rate given to us, The expected total value after 18 years =A = P(1.10)^n = $1,000 × (1.10)^18 = $5,559.92.
Answer:
$5,559.92

It takes Daphne 25 minutes to assemble a model plane. During her work day Daphne takes 30 minutes for lunch and one 15 minute break. Which inequality could Daphne use to determine the number of model planes
she can assemble in her 8 hour work day?
25p - 458
Answer:
y=25p-45Step-by-step explanation:
We first of all start by cumulating all the time she spent for break
lunch= 30min
break= 15min
total break= 45min
also the time taken to assemble one model plane 25min
let the number of hours be p
and the total number of model plane be y
The model is
y=25p-45
Answer: 25p +45 <480
