5 over 2
Because if x = 4
3x4=12
12-6=6

Find the average squared distance between the points of r{(x,y): 0x, 0y} and the point (,)
ivolga24 [154]

The average squared distance between the points is their variance

The average squared distance is 8/3

<h3>How to determine the average squared distance?</h3>

The given parameters are:

R={(x,y): 0<=x<=2, 0<=y<=2}

The point = (2,2).

f(x,y) = (x-2)² + (y-2)²

The squared distance is calculated as:

D² = f(x,y) = (x-2)² + (y-2)²

Where the area (A) is:

A = xy

Substitute the maximum values of x and y in A = xy

A = 2 * 2

A = 4

The minimum values of x and y are 0.

So, the limits for the integrals are 0 to 2

The integral becomes

D\² = \int \int (x-2)\² + (y-2)\² dx dy

Expand

D\² = \int \int x\² -4x + 4 + (y-2)\² dx dy

Evaluate the inner integral with respect to x from 0 to 2

D\² = \int \frac 13x^3 -2x^2 + 4x + x(y-2)\² |\limits^2_0 dy

Expand

D\² = \int [\frac 13(2)^3 -2(2)^2 + 4(2) + (2)(y-2)\²] dy

Simplify

D\² = \int \frac 83 + (2)(y-2)\² dy

Expand

D\² = \int \frac 83 + 2y^2-8y + 8 \ dy

Evaluate the integral with respect to y from 0 to 2

D\² = [\frac 83y + \frac 23y^3- 4y^2 + 8y ]|\limits^2_0

Expand

D\² = \frac 83*2 + \frac 23*2^3- 4*2^2 + 8*2

D² = 32/3

The average squared distance (AD²) is calculated as:

AD² = D²/A

So, we have:

AD² = 32/3 \div 4

Evaluate the quotient

AD² = 32/12

Simplify

AD² = 8/3

Hence, the average squared distance is 8/3

Is there
Basile [38]

Answer:

no

Step-by-step explanation:

no because 29 is a prime number, meaning its only factors are 1 and 29. if you were to have more than 1 book on each shelf then you would go into half and quarters of books.

The description below represents Function A and the table represents Function B:
ICE Princess25 [194]
The expression in A is equal to: 
                      y = 8 + 3x
It can be observed that the equation is in the slope-intercept form which is equal to,
                     y = mx + b
where m is slope and b is intercept.

The slope and intercept therefore of this equation of the line are equal to 3 and 8, respectively.

For Part B:
 The slope of the line can be calculated through the equation,
                           m = (y₂ - y₁) / (x₂ - x₁)
Substituting,
                           m = (5 - 2)/ (0 - -1) = 1.5

The intercept, b, is the value of y when x = 0. From the tabulation, y = 5 when x = 0. Thus, the intercept is equal to 5.

Comparing the slopes and intercepts of the equations, we can say that the slope of the second is only half that of the first and the intercept of the second is 3 less than that of the first equation.

In hypothesis​ testing, does choosing between the critical value method or the​ P-value method affect your​ conclusion? Explain.
slamgirl [31]

Answer:

A.

Step-by-step explanation:

​Yes, because the critical value method uses critical​ value(s) to identify the rejection​ region(s). The​ P-value method compares the​ P-value with the level of significance alpha.

Explanation:  When you reduce your significance value, the critical value either gets smaller, or larger depending on the tails.  This means that your test statistic would also have to get smaller or larger depending on the tail in order to reject the null hypothesis.

At test that rejected the null hypothesis at 5% may not reject it at 1%
