what is the constant of proportionality, y/x?

​

Answer: A

Step-by-step explanation:

Only the first scatterplot has the first data point correctly plotted.

Using the formula for the closest integer, it is found that Alejandro is not correct, as the integer is of 48 and not 52.

The integer that has square root n is given by:

S(n) = n².

Hence the integer that has a square root closest to n is given by:

C(n) = n² - 1.

In this problem, we want the square root closest to n = 7, hence:

C(7) = 7² - 1 = 48.

Which is a different value than 52, hence Alejandro is not correct.

Answer:

y = -2/3 x + 5/3

Step-by-step explanation:

y = mx + b

y = -2/3 x + b

1 = -2/3 × 1 + b

3/3 + 2/3 = b

b = 5/3

y = -2/3 x + 5/3

The Venn probability that a a day in early March would have either rain or snow is given by:

4.) .26

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

In this problem, we have that the probabilities are given as follows:

[tex]P(A) = 0.18, P(B) = 0.12, P(A \cap B) = 0.04[/tex]

Hence:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

[tex]P(A \cup B) = 0.18 + 0.12 - 0.04[/tex]

[tex]P(A \cup B) = 0.26[/tex]

The value of x when the line segment st is dilated to create line s't' about point q is 2.5 units

The given parameters are:

qs = 2

qt = 1.2

tt' = 1.5

ss' = x

To calculate the value of x, we make use of the following equivalent ratio

ss' : qs = tt' : qt

So, we have:

x : 2 = 1.5 : 1.2

Express as fractions

x/2 = 1.5/1.2

Multiply both sides by 2

x = 2 * 1.5/1.2

Evaluate the product

x = 2.5

Hence, the value of x is 2.5 units

Both words are used to talk about how long the boundary is of a 2D figure.  Think of circumference as a special case of finding the perimeter.  The term circumference refers to the perimeter of a figure without sides or something like a circle or arc.

So if we were to look at a rectangle and try to determine how long the boundary is we would use perimeter.  On the other hand, if we have a circle we have no way to track how long each side is therefore we use circumference.

Perimeter is a wide term which means the total length of the surrounding (lines ) of the 2D figure.

circumference is the special case of the perimeter in which perimeter of Arc or circular lines are taken in count .

On solving

So

Width

A rectangle has a length of (2x+1) units, a width of (x-7) units and an Area of 17 square units. Find the dimensions of the rectangle.

In this question we are provided with the length of a rectangle (2x + 1) units and the width of the rectangle (x - 7). It is also given that the area is 17 units². We are asked to calculate the length and width of the rectangle.

First we will find the value of x

We know,

[tex] \bull \: \small\boxed{ \rm{ Area_{(rectangle)} = Length × Width}}[/tex]

Substituting the values we get

[tex] \small\sf{ (2x + 1 ) (x - 7) = 17}[/tex]

[tex] \small\rm{ 2x( x - 7) + 1(x - 7) = 17}[/tex]

[tex] \small\rm{ 2 {x}^{2} - 14x + 1(x - 7) = 17}[/tex]

[tex] \small\rm{ 2 {x}^{2} - 13x - 7 = 17}[/tex]

[tex] \small\rm{2 {x}^{2} - 13x - 7 - 17 = 0 } [/tex]

[tex] \small\rm{2 {x}^{2} - 13x - 24 = 0} [/tex]

[tex] \small\rm{x = \dfrac{13 + 19}{2 \times 2} } [/tex]

[tex] \small\rm{ x = \dfrac{32}{4} = 8}[/tex]

[tex] \small\sf{x = 8} [/tex]

Now we will substitute the value of x

Length = (2x + 1) = 2 × 8 + 1 = 16 + 1 = 17 units

Width = (x - 7) = 8 - 7 = 1 units
