Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

Answer:

$x=28-5.2-12.9$ , 9.9 ounces of water remaining.

Step-by-step explanation:

Given:

Dylan drank 5.2 ounces of water before soccer practice, and 12.9 ounces after practice.

Before he drank any water, there were 28 ounces of water in the container.

Question asked:

Which expression can be used to find the amount of water remaining?

Solution:

Let $x$ the amount of water remaining.

Total quantity of water in the container = 28 ounces

Before practice, Dylan drank = 5.2 ounces

After practice, Dylan drank = 12.9 ounces

Remaining amount of water = Total quantity of water in the container - Amount of water is drunk before practice - Amount of water is drunk before practice

$x=28-5.2-12.9\\ \\ x=28-18.1\\ \\ x=9.9\ ounces$

Thus, 9.9 ounces of water remaining in the container.

Julia plays volleyball and finished the regular season with 25 digs. The graph relates her total number of digs for the season t

Law Incorporation [45]

We need to find an equation in the form $y=mx+b$ .

To find $m$ , we use the formula:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

We'll use the points $(0, 25)$ and $(4, 37)$ :
$m=\frac{37-25}{4-0}=\frac{12}{4}=3$

The value of $b$ (the y-intercept) is the value of $y$ when $x=0$ , which is 25.

So the equation is $y=3x+25$ (choice A).

Answer:

Step-by-step explanation:

Volume of the figure = Base area * height

Base area:

Base area = area of trpezium + area of triangle

Trapezium:

a, b area the length of parallel sides and h is the height of trapezium.

a = 8 m ; b = 5 m & h = 3 m

$\boxed{ \text{ Area of trapezium = $\dfrac{(a +b)*h}{2} $}}$

$=\dfrac{(8+5)*3}{2}\\\\\\=\dfrac{13*3}{2}\\\\\\= \dfrac{39}{2}\\\\\\= 19.5 \ m^{2}$

Triangle:

height = 4 m & base = 8 m

$\boxed{\text{Area of triangle =$\dfrac{1}{2}*base*height$}}$

$=\dfrac{1}{2}*8*4\\\\\\= 4*4\\\\= 16 \ m^{2}$

Base area = 19.5 + 16

= 35.5 m²

Volume of the figure = Base area * height

= 35.5 * 14

= 497 m³

Answer:

None of these can be triangles.

Step-by-step explanation:

All triangles’ side lengths must follow this pattern - the two shortest sides must be GREATER than the longest when added together. 6 + 4 < 10, so this isn’t a triangle. 3 + 8 = 11, so this isn’t a triangle. 8.4 + 7.7 < 16.6, so this isn’t a triangle. Lastly, 4 + 3 < 16, so this isn’t a triangle. Hope this is accurate & helpful! Best of luck.
