Is the ratio 4.2:1.5 proportional to the ratio12.6:4.5? Explain.

Answers

Answer:

No

Step-by-step explanation:

All the numbers have to be multiplied by the same amount for it to be proportional

A proportional amount to 4:2:1:5 would be 12:6:3:15

They have all been multiplied by the same number 3

Answer:

Yes, the ratio is proportional

Step-by-step explanation:

given 4.2 : 1.5 =? 12.6 : 4.5 is it proportional

it must follow the means extremes property

[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]

a*d = b*c, so let's plug in the values

[tex]\frac{4.2}{1.5}[/tex] =? [tex]\frac{12.4}{4.5}[/tex]

(4.2)*(4.5) =? (1.5)*(12.6)

18.9 = 18.9 which is true; therefore the ratio is proportional

What is the equation of the line that passes through the point (8,-4) and has a slope of 1/2

Answers

y+4=1/2(x-8) pls can i have brainliest luv u

The equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

What is the Point-slope form?

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

This is the required equation of a line in a point-slope form.

We know that Point-Slope Form:

y - y₁ = m(x- x₁)  

Where x₁ - x coordinate and y₁ - y coordinate

m - slope

Point (8,-4)

Then Slope m = 1/2

Now the equation as;

y + 4 = 1/2(x - 8)

 y  = -1/2(x -4) - 4

y = -x/2 + 2 - 4

y = -x/2 - 2

Hence, the equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

32 25 18 11 4
These are the first 5 terms of sequence
Find(a)6th term
(b)nth term
(c)which term is equal to -332
​

Answers

Answers

A 3

B t = -7n +39

C 51.571

It is declining!

32 to 25 decreases by 7

25 to 18 decreases by 7

18 to 11 decreses by 7

The sequence is linear!

39 is the 0th term and our numbers are decreasing by 7 each term.

t = -7n +39 is our equation

a) -7(6) + 39

-49 + 39

3

b) to find nth term replace the term with n in this equation:

t = -7n +39

c) -332 = -7n +39

Subtract 39 from both sides!

-361 = -7n

Divide both sides by -7!

n = 51.571

The 6th term will be equal to -3, the nth term of the sequence will be equal to -7n + 39 and the term will be the 53rd term.

What is the arithmetic sequence?

Two definitions are given for an arithmetic sequence. A "series where the variances in between every two succeeding terms are the same" is what it is.

Each term in an algebraic expression is created by multiplying its previous term by a specified integer (either positive, negative, or zero).

As per the given information in the question,

The sequence is given as:

32, 25, 18, 11, 4

(a)

a = 32

d = 25 - 32 = -7

n = 6

Then,

a₆ = a + (n - 1)d

a₆ = 32 + (6 - 1)(-7)

= 32 - 35

= -3

(b)

Find the nth term.

[tex]a_n[/tex] = a + (n - 1)d

= 32 + (n - 1)(-7)

= 32 -7n + 7

[tex]a_n[/tex] = -7n + 39

(c)

-332 = 32 + (n - 1)(-7)

-332 - 32 -7 = -7n

n = -371/-7

n = 53rd term.

Step-by-step explanation:

The distribution of house prices will be skewed to the right with possible outliers. This is because the regular median prices are still fairly far apart from each other with roughly $300,000 in difference between them. Also since there are some extreme house prices also included that greatly surpass the normal range these would be considered outliers in the data set.

Step-by-step explanation:

The constant in the equation is 1, so that is the value when x=0. No answer choice can be correct unless it includes the value 1. The only viable choice is A.

_____

If you want to go to the trouble to evaluate the expression for the different values of x, you can. It often works well to rewrite the expression to "Horner form":

  (2x -1)x +1

For x = -2, this is (2(-2) -1)(-2) +1 = (-5)(-2) +1 = 11

For x = 0, this is 1

For x = 2, this is (2(2) -1)(2) +1 = (3)(2) +1 = 7

So, the range for the given domain is {1, 7, 11} . . . . . matches choice A

Giddy-up, cowboys and girls! In the Southwest during early half of the 1800s, cows were only worth 2 or 3 dollars apiece. They roamed wild, grazed off the open range, and were abundant. Midway through the century though, railroads were built, and the nation was connected. People in the Southwest could suddenly ship cows in freight trains to the Northeast. The Yankees there had a growing taste for beef and were willing to pay for it. Out of the blue, the same cows that were once worth a couple of bucks were now worth between twenty and forty dollars each. The only problem was that they had to get these cows to the train station. A new profession emerged from this. It became lucrative to wrangle up a drove of cattle and herd them to the nearest train town. Of course, it was dangerous too. Cowboys were threatened at every turn. They faced cattle rustlers, stampedes and extreme weather. But they kept pushing those steers to the train station. By the turn of the century, barbed wire killed the open range. Some may say the cowboy, too, was killed by barbed wire. Maybe, but it was the train that birthed them.
