Answer:

The radius is [tex] 2\sqrt{15} [/tex]

The center is (3, 3)

Step-by-step explanation:

Equation of circle in standard form with center at (h, k) and radius r:

[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]

We need to complete the square in x and y.

[tex] x^2 + y^2 - 6x - 6y = 42 [/tex]

Separate x-terms and y-terms:

[tex] x^2 - 6x + ~~~~~y^2 - 6y + ~~~~~ = 42 + ~~~~~ + ~~~~~ [/tex]

To complete the square, you square half of the linear term's coefficient.

Linear term in x: -6x

Coefficient: -6

Half of the coefficient: -3

Square half of the coefficient: 9

We need to add 9 to both sides to complete the square in x.

The linear term in y is -6y, so we do the same and we also need to add 9 to both sides to complete the square in y.

[tex] x^2 - 6x + 9 + y^2 - 6y + 9 = 42 + 9 + 9 [/tex]

[tex] (x - 3)^2 + (y - 3)^2 = 60 [/tex]

Now that we have the equation in standard form, we can get the radius and center of the circle.

[tex] r^2 = 60 [/tex]

[tex] r = \sqrt{60} [/tex]

[tex] r = \sqrt{4 \times 15} [/tex]

[tex] r = 2\sqrt{15} [/tex]

The radius is [tex] 2\sqrt{15} [/tex]

The center is (3, 3)

An observation is considered an outlier if it is below:____________.
An observation is considered an outlier if it is above:____________.

Answers

Answer/Step-by-step explanation:

Given the five summary of a data set:

45 - min

46 - Q1

51 - Median

60 - Q3

66 - Max

Thus, any number less than [tex] Q_1 - (1.5*IQR) [/tex], or any number that is greater than [tex] Q_3 + (1.5*IQR) [/tex] would be considered an outlier.

The IQR of the data set = Q3 - Q1 = 60 - 46 = 14

Thus,

[tex] Q_1 - (1.5*IQR) = 46 - (1.5*14) = 46 - 21 = 25 [/tex]

Therefore, an observation is considered an outlier if it is below: 25.

[tex] Q_3 + (1.5*IQR) = 60 + (1.5*14) = 60 + 21 = 81 [/tex]

Therefore, an observation is considered an outlier if it is above: 81.

FIND THE VALUE OF X2 FOR 20 DEGREES OF FREEDOM AND AN AREA OF .010 IN THE RIGHT TAIL OF THE CHI SQUARE

Answers

Answer:

The critical value of chi-square for 20 degrees of freedom and 0.01 level of significance is 37.57.

Step-by-step explanation:

We have to find the value of chi-square for 20 degrees of freedom an area of 0.01 in the right tail of the chi-square.

As we know that in the chi-square table; there is one vertical column represented by 'P' (the level of significance and one horizontal column represented by '[tex]\nu[/tex]' which is degrees of freedom.

Here, the degrees of freedom given to us is 20.

and the level of significance is 0.01 or 1% for the right tail of chi-square.

By looking at the chi-square table, the critical value of chi-square for 20 degrees of freedom and 0.01 level of significance is 37.57.

Cross multiply:

Isolate the "v" variable:

[tex]6v - 18 + 18 = 36 + 18 + 8v[/tex]

[tex]6v = 54+ 8v[/tex]

[tex]6v - 8v = 54+ 8v - 8v[/tex]

Which data set could be represented by the box plot shown below?

Answers

Answer/Step-by-step explanation:

The answer choices to this question showing possible set of data that could be represented by the box plot is missing.

However, here's how to find out which data set could be represented by the box plot.

The box plot given displays of a five-number summary consisting of,

1. The minimum value = 24

2. The second quartile = 27

3. The median value = 31

4. The third quartile = 33

5. The maximum value = 34

With these values known, you can easily find out which data set the box plot represents. Thus, the data set that has a min value of 24, max value of 34, and a median of 31 should be the data set that the box plot is representing. If you have more than one options having these same three values, then proceed to find the second and third quarter to determine which one is the most appropriate.

Answer:

Step-by-step explanation:

The plant starts out at 15 cm tall, therefore the y intercept is (0,15) and there is an x intercept but it isn't valid in this case as a plant cannot grow backwards (I assume). The domain would be (0,infinity) and the range would be (15,infinity).

Solve the equation below and find the variation constant, k .Find y when x = 7 and z=5, if y varies jointly as x and 2, and y= 14 and x = 4 when z= 3​

Answers

Answers:

Variation Constant: k = 7/6

y = 245/6 when x = 7 and z = 5

====================================

Explanation:

"y varies jointly as x and z" means that y = kxz

We have (x,y,z) = (4,14,3) as one triple, so,

y = kxz

14 = k*4*3

14 = 12k

12k = 14

k = 14/12

k = 7/6 is the variation constant

The equation goes from y = kxz to y = (7/6)xz

----------------

Plug in x = 7 and z = 5 to find y

y = (7/6)xz

y = (7/6)*7*5

y = (7/6)*(7/1)*(5/1)

y = (7*7*5)/(6*1*1)

y = 245/6

Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount monthly plus a charge for each cubic foot of water used. A household using 1500 cubic feet was billed $80, while one using 2100 cubic feet was billed $92. Write an equation for the total cost of a resident's water as a function of cubic feet of water used.

Answers

Answer:

A = 50 + 0.02x

Step-by-step explanation:

Let the fixed amount be m

Let the charge for each cubic ft used be c

Let the amount of cubic ft of water used be x.

Let the total cost per month be A

Now, for the first household, they used 1500 cubic feet in a month and were billed $80.

This means, x = 1500 ft³ and A = $80

Since, we are told they are charged a fixed amount plus a fee per cubic ft consumed. We can say that;

m + cx = A

Thus,

m + 1500c = 80 - - - - (eq1)

For 2nd household:

They used 2100 cubic feet was billed $92.

Thus;

m + 2100c = 92 - - - - (eq 2)

Let's subtract eq1 from eq 2 to get;

2100c - 1500c = 92 - 80

600c = 12

c = 12/600

c = 0.02

Putting 0.02 for C in eq1 gives;

m + 1500(0.02) = 80

m + 30 = 80

m = 80 - 30

m = 50

From m + cx = A, we can say that;

50 + 0.02x = A

Find the relative extrema of the function, if they exist. Also, state the intervals where the function is increasing or decreasing. g

Answers

Answer:

The question is not complete. I will explain relative extrema and how to calculate it.

Step-by-step explanation:

The singular of extrema is extremum and it is simply used to describe a value that is a minimum or a maximum of all function values.

A function will have relative extrema (relative maximum or relative minimum) at points in which it changes from decreasing to increasing, or vice versa.

So if f(y) is a function of y

Function f(d) will be is a relative maximum of f(y),

if there exists an interval (a, b) containing d

such that for all y in (a, b) , f(y) ≤ f(d)

Function f(d) will also be a relative minimum of f(y),

if there exists an interval (a, b) containing d

such that for all y in (a, b) , f(y) ≥ f(d)

Kindly note that If f(d) is a relative extrema of f(y), then the relative extrema occurs at y = d.

For the local extrema of a critical point to be determined, the function must go from increasing, that means positive  [tex]f^{'}[/tex], to decreasing, that means negative [tex]f^{'}[/tex], or vice versa, around that point.

[tex]f^{'}[/tex] is determined by finding the first derivative of the function f(y). The relative extrema will therefore allows us to check for any sign changes of f′ around the function's critical points.
