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

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.

Answer:

[tex] Volume = 12\sqrt{7} [/tex] cubic units

Step-by-step explanation:

Volume of the square pyramid is given as ⅓*area of base*height of pyramid.

Where,

Area of base = 6*6 = 36

Height of pyramid = altitude = [tex] \sqrt{7} [/tex] units

Plug the values into the formula to find volume.

[tex] Volume = \frac{1}{3}*36*\sqrt{7} [/tex]

[tex] Volume = 12*\sqrt{7} [/tex]

[tex] Volume = 12\sqrt{7} [/tex] cubic units

Hi there! :)

Answer:

[tex]\huge\boxed{v = -27}[/tex]

[tex]\frac{v-3}{4} = \frac{9+2v}{6}[/tex]

Cross multiply:

[tex]6 ( v - 3) = 4 ( 9 + 2v)[/tex]

Distribute:

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

Isolate the "v" variable:

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

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

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

[tex]-2v = 54\\\\v = -27[/tex]

Answer:

2x + 4y = $50

x = $5, and y = $10

Step-by-step explanation:

let the price of student's ticket be represented by $x, and that of adult by $y. So that:

2x + 4y = $50 ................  1

But, given that adult tickets are $5 more that student tickets.

i.e y = x + $5  .................  2

Substitute equation 2 into 1, to have;

2x + 4(x + $5) = $50

2x + 4x + $20 = $50

6x = $30

x = $5

From equation 2,

y = 5 + 5

  = $10

Therefore, the price of student tickets is $5 and adult tickets is $10.

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

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

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

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.

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:

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.
