Answer:

Step-by-step explanation:

There are 3 data sets given as

I)   x                         7 8 9 10 11 12 13    Total

   Frequ                  1  2  1   2  2 0     2

Mean dev|x-10|*f    3 4  1   0    3  0   6      17

II)     x                         7 8 9 10 11 12 13    Total

   Frequ                     2  3 0  0  1  1   3

Mean dev|x-10|*f        6  6  0  0 1  2 9     24

III)   x                         7 8 9 10 11 12 13    Total

   Frequ                     0 0 4  4  1  0 1

Mean dev|x-10|*f        0  0 4 0 1  0 3        8

Thus we find the middle one Jason has the highest deviation.

The point A (-5, -2) is reflected over the line y = -1, and then is reflected over the line x = 3. What are the coordinates of A
dmitriy555 [2]
When A is reflected over y=-1, -1+(-1-(-2))=0, it lands on (-5, 0), when it is then reflected over x=3, 3+(3-(-5))=11, it lands on (11,0)

Solve the integral:<br><img src="https://tex.z-dn.net/?f=%20%5Cint%20%5C%3A%20%20%7Be%7D%5E%7B%20-%20%20%7Bx%7D%5E%7B2%7D%20%7D%

e^{-x^2} has no antiderivative in terms of elementary functions (polynomials, exponentials, logarithms, trigonometric functions, etc), but there is a special function defined to fit that role called the error function, \mathrm{erf}(x), where

\mathrm{erf}(x)=\displaystyle\frac2{\sqrt\pi}\int_0^xe^{-t^2}\,\mathrm dt

By the fundamental theorem of calculus, we can see that

\dfrac{\mathrm d}{\mathrm dx}\mathrm{erf}(x)=\dfrac2{\sqrt\pi}e^{-x^2}

which means we have

\displaystyle\int e^{-x^2}\,\mathrm dx=\dfrac{\sqrt\pi}2\mathrm{erf}(x)+C

A flower box is 3 ft. Long, 2 3/4 ft. Wide, and 1/2 ft. Deep. How many cubic feet of dirt can it hold? A. 4 1/8 B. 5 3/4 C. 6 1/
pochemuha

Answer:

The box can hold 4 1/8 cubic feet of dirt

Step-by-step explanation:

What we simply have to find here is the volume of dirt it can take

To get this, we have to multiply the dimensions of the box

We have this as follows

Volume or box = length * width * height

Volume of box = 2 3/4 * 1/2 * 3

Volume of box = 11/4 * 3 * 1/2 = 33/8 = 4 1/8 cubic feet

A function is defined as a set of points for every x-value, there is only one y-value.
So, you can't have two y-values for every x-value.

Thus, (B) would be a relation, because x = 7 has two y-values, and as such, doesn't satisfy the condition of a function.
