Answer:

1. x = 2/3y + 8/3

2. x=−y+1

Step-by-step explanation:

Solve for x

3x−2y=8

Add 2y to both sides.

3x−2y+2y = 8+2y

3x=2y+8

Divide both sides by 3.

3x/3 = 2y+8/3

x = 2/3y + 8/3

Answer:

x = 2/3y + 8/3

#2

solve for x.

x+y=1

Add -y to both sides.

x+y+−y=1+−y

x=−y+1

Answer:

x=−y+1

solve for y.

x+y=1

Add -x to both sides.

x+y+−x=1+−x

y=−x+1

Answer:

y=−x+1

The probability that the four houses selected for a free newspaper will all be even numbered houses is: 1/42.

Probability refers to the possibility of the occurrence of an event.

P(E) = probability of occurrence of an event E = Number of favorable outcomes, divided by total number of outcomes

Now, according to question,

There are 10 houses numbered 1-10. Thus the number of even numbered houses = 5 (2, 4, 6, 8, 10)

The probability that the first selected house for free newspapers is even numbered = 5/10 = 1/2

The probability that the second selected house for free newspapers is even numbered = 4/9

The probability that the third selected house for free newspapers is even numbered = 3/8

The probability that the fourth selected house for free newspapers is even numbered = 2/7

The final probability that the four houses selected for a free newspaper will all be even numbered houses is = 1/2(4/9)(3/8)(2/7) = 1/42

Hence, The probability that the four houses selected for a free newspaper will all be even numbered houses is: 1/42.

The technique that most clearly minimizes the likelihood that any outcome differences between the experimental and control groups is e. random assignment.

A methodology used to divide research participants into two groups—the treatment group, also known as the experimental group, and the control group—by randomization is known as random assignment, also known as random placement.

Every research volunteer has an equal chance of being assigned to any of the groups thanks to this randomization mechanism.

In studies, random assignment is a method used to divide participants into different research groups with similar characteristics so that the groups are equal at the start of the investigation.

The equation of the line that is perpendicular to the given line y = x + 6 and has an x-intercept of 6 is B. y = -x + 6.

A line is plotted on the cartesian plane and is straight, thus named a straight line. A straight line is a two-dimensional geometrical figure.

Given the line:

y = x + 6

Compare the equation with

y = mx + c,

m = 1 and c= 6.

As it is given that the new line is perpendicular to the old one, then

the slope of the new line, m' [tex]= -\frac{1}{m} = -\frac{1}{1} = -1[/tex].

As the x-intercept is 6, c' = 6.

So, the equation of the new line is

Answer:

y = [tex]\frac{1}{2}[/tex] x - 2

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 )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (6, 1 ) and (x₂, y₂ ) = (- 6, - 5 )

m = [tex]\frac{-5-1}{-6-6}[/tex] = [tex]\frac{-6}{-12}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 1 )

1 = 3 + c ⇒ c = 1 - 3 = - 2

y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line
