Answer:
3x + y = 20 and x - 2y = - 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 )
(a)
Given
3x + y = 17 ( subtract 3x from both sides )
y = - 3x + 17 ← in slope- intercept form
with slope m = - 3
Para;;el lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (4, 8) into the partial equation
8 = - 12 + c ⇒ c = 8 + 12 = 20
y = - 3x + 20 ← in slope- intercept form
Add 3x to both sides
3x + y = 20 ← in standard form
--------------------------------------------------------
(b)
Given
y + 2x = 13 ( subtract 2x from both sides )
y = - 2x + 13 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form
Multiply through by 2 to clear the fraction
2y = x + 4
x - 2y = - 4 ← in standard form

Are the events "selecting a female" and "selecting a students who has brown eyes" independent?
Answers
Answer:
No, the events are not independent.
Step-by-step explanation:
Suppose that there are two events, A and B.
Such that first happens the event A and then the event B.
If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.
In this case, if we have only the event "selecting a student who has brown eyes" (at random)
The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:
P = 91/200 = 0.455...
Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.
In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:
P = 32/90 = 0.355...
So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.
A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answers
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places
