Answer:

Well, you find the mean by adding up all the totals then dividing by how many sets of the totals you have. the mean gives you the average of the whole data set, which can be helpful to know when you are maybe trying to raise awareness for something and you want to know the average, I don't know, animals killed in the forest fire, sadly.

Answer:

$\large\boxed{(x-2)^2+(y-1)^2=34}$

Step-by-step explanation:

The equation of a circle in standard form:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have the endpoints of the diameter: (-1, 6) and (5, -4).

Midpoint of diameter is a center of a circle.

The formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

Substitute:

$h=\dfrac{-1+5}{2}=\dfrac{4}{2}=2\\\\k=\dfrac{6+(-4)}{2}=\dfrac{2}{2}=1$

The center is in (2, 1).

The radius length is equal to the distance between the center of the circle and the endpoint of the diameter.

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the points (2, 1) and (5, -4):

$r=\sqrt{(5-2)^2+(-4-1)^2}=\sqrt{3^2+(-5)^2}=\sqrt{9+25}=\sqrt{34}$

Finally we have:

$(x-2)^2+(y-1)^2=(\sqrt{34})^2$

How do you do this question?

katen-ka-za [31]

Answer:

Step-by-step explanation:

∫ sin²(x) cos(x) dx

If u = sin(x), then du = cos(x) dx.

∫ u² du

⅓ u³ + C

⅓ sin³(x) + C

Evaluate between x=0 and x=π.

⅓ sin³(π) − ⅓ sin³(0)

Solve the following system of equations. Express your answer as an ordered pair in the format (a,b), with no spaces between the

Contact [7]

Solve it by substitution. First let's rewrite the first equation (3x+4y=16) so we have y = something, then we'll substitue that in to the other equation.
3x+4y=16
4y=-3x+16
y=-3/4x+4

Now we can substitute this into the other equation.

A rectangle has an area of 8/9 square yard. Which could be the dimensions of the rectangle?

katen-ka-za [31]

Answer:

There could be any number of dimensions as long as the two dimensions multiply to 8/9

Step-by-step explanation:

One example of this would be 2 by 4/9

2 * 4/9 = 8/9
