Answer:

y = 3x - 8

Step-by-step explanation:

The equation of a line that is parallel to -x + 3y = 6 and passes through the point (3,5) is y = 1 / 3 x + 5

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, the equation of a line that is parallel to -x + 3y = 6 and passes through the point (3,5) can be found as follows:

Parallel lines have the same slope.

-x + 3y = 6

3y = x + 6

y = 1  / 3 x + 2

Therefore, the slope is 1 / 3. Let's find the y-intercept using (3, 5).

y = 1 / 3 x + b

5 = 1 / 3 (3) + b

b = 5

Therefore, the equation is y = 1 / 3 x + 5

In the simple random sample, the probability that at least half of the students have brown eyes is 0.400

Probability is defined as the chance of occurrence of an event.

Probability is defined as follows:

P(E)=[tex]\frac{no of required outcome}{total of possible outcomes}[/tex]

The given parameters are:

The sample size= 30 students

Number with brown eye=40%

40% x 30 = [tex]\frac{40}{100} * 30[/tex]

=12

This means that there 12 students out of 30 that have brown eyes.

Applying the probability formula

[tex]\frac{12}{30}[/tex]= 2/5

In conclusion 0.400 of the students have brown eyes.

The coordinates point C of the given line segment AC is C(0, -2) whose midpoint is at B.

To calculate the midpoint of a line segment, find the average for the coordinates of the endpoints of the line segment. I.e.,

Consider a line segment AC, B is its midpoint.

So, the coordinates of B are (Where we have A(x1, y1) and C(x2, y2))

B(x, y) = [tex](\frac{x1+x2}{2}, \frac{y1+y2}{2})[/tex]

It is given that, B is the midpoint of a line segment AC.

Where A has coordinates as (-3, 4) and B has coordinates as (-1 1/2, 1).

So, the coordinates of the other end point C of the given line segment are calculated as

B(x, y) = [tex](\frac{x1+x2}{2}, \frac{y1+y2}{2})[/tex]

⇒ (-1.5, 1) = [tex](\frac{-3+x2}{2}, \frac{4+y2}{2})[/tex]

⇒ -1.5 = (-3 + x2)/2 and 1 = (4 + y2)/2

⇒ -3 = -3 + x2 and 2 = 4 + y2

⇒ x2 = 0 and y2 = 2 - 4 = -2

Therefore, point C has coordinates as (0, -2).

The amount of diesel required to create slash burn fuel is = 112 gallons

The amount of gas required to create slash burn fuel = 28 gallons

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The total amount of slash fuel = 140 gallons

The ratio of diesel to gas in slash fuel is = 8 : 2

Let the amount of diesel required to create slash burn fuel be = 8x

Let the amount of gas required to create slash burn fuel be = 2x

So , the equation of proportion is given by

Total amount of slash fuel = amount of diesel required to create slash burn fuel + amount of gas required to create slash burn fuel

Substituting the values in the equation , we get

Total amount of slash fuel = 8x + 2x

8x + 2x = 140

10x = 140

Divide by 10 on both sides of the equation , we get

x = 14 gallons

Substituting the value of x in the above expressions , we get

Amount of diesel required to create slash burn fuel = 8x

Amount of diesel required to create slash burn fuel = 8 x 14

Amount of diesel required to create slash burn fuel = 112 gallons

And ,

Amount of gas required to create slash burn fuel = 2x

Amount of gas required to create slash burn fuel = 2 x 14

Amount of gas required to create slash burn fuel = 28 gallons

Hence ,

The amount of diesel required to create slash burn fuel is = 112 gallons

The amount of gas required to create slash burn fuel = 28 gallons

Probability of winning a grand prize is 1/10

What is the probability of two independent events?

If A and B are two independent events, then P(A and B) = P(A) * P(B).

If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).

Solution:

P(A) = no. of A / total possibility

      = 4/10

P(B) = no. of 1's/total possibility

      = 3/12

     =  1/4

Now,

To win a grand prize you need an "A" and "1" .

∴ P(A and B) = P(A) × P(B)

                    = 4/10 × 1/4

         P(A and B) = 1/10

Now ,

To win a basic prize you need to spin an "A" or a "1"

∴ P(A or B) = P(A) + P(B) - P(A and B)

Using the elimination method, you may either add or subtract the equations to produce an equation in one variable. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

According to the given information

Let number of drinks = x

Let number of candies = y

Christian bought 8 drinks and 10 candies and it costed $94

So the equation becomes

8x + 10 y = $94

Other guy bought 9 drinks and 6 candies and it costed $79.50

So the equation becomes

9x + 6y = $79.50

By applying elimination method

9x + 6y = $79.50

Dividing by 2

3x + 2y = $26.5

multiplying the above equation by 5

15x + 10y =  $132.5

8x + 10 y = $94

Subtract the following equation

7x = 38.5

x = 5.5

substituting the value of x in above one equation we get

y = 5

So the cost of each drink is $5.5

the cost of each candy is $5

An equation for the line in slope-intercept form is y=(6/5)x+8

The same number is given for every two different points on the same line when the ratio is stated as a quotient ("rise over run"). On a falling line, there is a negative "rise." In a diagram that depicts a roof or a road as a description or a design, the line may be practical as established by a road surveyor.

The steepness, incline, or grade of a line can be approximated by the slope's absolute value. The slope of a line determines how steep it is.

From the graph,

The line passes through the points (0,8) and (5, 14)

Slope m=(14-8)/(5-0)

m=6/5

(0, 8) passes through the line y=mx+c

So, 8=6(0)/5+c
