Step-by-step explanation:

Let a represent the number of adult tickets sold. Then the total revenue was ...

  8.60a +5.50(131 -a) = 946.80

  8.60a -5.50a +720.50 = 946.80 . . . . eliminate parentheses

  3.10a = 226.30 . . . . . . subtract 720.50, collect terms

Answer:

[tex]\bold{\dfrac{63}{143}}[/tex]

Step-by-step explanation:

Number of Democrats = 6

Number of Republicans = 7

Total number of members = 6+7 = 13

To find:

Probability of selecting two Democrats and two Republicans if 4 members are selected in the committee = ?

Solution:

This is a selection problem.

Total number of ways to select 4 members in the committee out of total 13 = [tex]_{13}C_4 = \dfrac{13\times 12\times 11\times 10}{4\times 3\times 2} = 715[/tex]

Number of ways to select 2 Democrats = [tex]_{6}C_2 = \dfrac{6\times 5}{2} = 15[/tex]

Number of ways to select 2 Republicans = [tex]_{7}C_2 = \dfrac{7\times 6}{2} = 21[/tex]

Number of ways to select 2 Democrats and 2 Republicans = 15 [tex]\times[/tex] 21 = 315

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, required probability:

[tex]\dfrac{315}{715} = \bold{\dfrac{63}{143}}[/tex]

Answer:

v < -7

Step-by-step explanation:

Step 1: Write out equation

-4v - 25 > 2v + 17

Step 2: Add 4v to both sides

-25 > 6v + 17

Step 3: Subtract 17 on both sides

-42 > 6v

Step 3: Divide both sides by 6

-7 > v

Step 4: Rewrite

v < -7

Answer:

Step-by-step explanation:

Formula for locating the Median of a grouped data = (N+1)/2 th where

N is the total number of defects.

Total defects = 10+18+13+15+9+12

Total defects = 77

Median value = (77+1)/2 th value

Median value = 78/2 = 39th value.

We will cummulate the frequency (number of defects up to the 38th value) and locate the corresponding observation value.

On cummulating:

10+18+13 = 41

We can see that the value of 38 falls on the third column(13), hence the median will be the equivalent number of observations i.e 3.

Therefore the sample median is 3

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{125 \: {cm}^{2} }}}}}[/tex]

Step-by-step explanation:

Let the width be 'w'

Length of a rectangle = 5w

Perimeter of a rectangle = 60 cm

Area of a rectangle = ?

First, finding the value of width ' w '

[tex] \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}[/tex]

plug the values

⇒[tex] \sf{60 = 2(5w + w)}[/tex]

Distribute 2 through the parentheses

⇒[tex] \sf{60 = 10w + 2w}[/tex]

Collect like terms

⇒[tex] \sf{60 = 12w}[/tex]

Swap the sides of the equation

⇒[tex] \sf{12w = 60}[/tex]

Divide both sides of the equation by 12

⇒[tex] \sf{ \frac{12w}{12} = \frac{60}{12} }[/tex]

Calculate

⇒[tex] \sf{w = 5}[/tex] cm

Finding the value of length ( l )

[tex] \sf{length = 5w}[/tex]

Substitute the value of w

⇒[tex] \sf{length = 5 \times 5}[/tex]

⇒[tex] \sf{length = 25 \: cm}[/tex]

Finally, Finding the area of rectangle having length of 25 cm and width of 5 cm

[tex] \boxed{ \sf{area \: of \: a \: rectangle = l \times b}}[/tex]

plug the values

⇒[tex] \sf{area \: = \: 25 \times 5}[/tex]

Multiply the numbers

⇒[tex] \sf{area \: = \: 125 \: {cm}^{2} }[/tex]

Answer:

There are two types of hypotheses tests. null and alternative

They are complements.

Step-by-step explanation:

There are two types of hypotheses tests. null and alternative

the table shows the summary of both tests.

True Situation                              DECISION

                                  Accept H0             Reject H0

                                                               (or accept Ha)

H0 is true          Correct decision       Wrong Decision

                            (no error)                     type I error          

H0 is false          Wrong Decision           Correct decision

                             type II error                 ( no error)    

The probability of making a type I error is conventionally denoted by alpha and that of committing a type II error is indicated by beta.

∝ = P ( type I error) = P (reject H0 / H0 is true)

β = P (type II error) = P (accept H0 / H0 is false)

When ∝ becomes larger, β tends to become smaller . There is inverse relationship between ∝ and β.

When H0 is true Ha is false when Ha is false H0 is true. So they are compliments of each other.

Answer:

The width is 4 inches

The length is 11 inches

Step-by-step explanation:

Let the width  be x inches

Let the length be (2x+3 )inches

Perimeter= 30 inches

therefore, 2(length +breadth)= perimeter

        =>2(2x+3+x)=30

        =>2(3x+3)=30

         =>6x+6=30

          =>6x=30-6

          =>6x=24

           =>x=24/6

           =>x=4

The width is 4 inches

The length is 11 inches  

To solve this question:

Doing this, we get that the length of the painting is: 11 inches.

Perimeter of a rectangle:

The perimeter of a polygon is the sum of it's sides.

For a rectangle, as the one given in the picture at the end of this answer, which is of the format of the painting, the perimeter is given by:

[tex]P = 2l + 2w[/tex]

Lisa is framing a rectangular painting the length is three more than twice the width.

This means that:

[tex]l = 3 + 2w[/tex]

Since we want to solve for the length, we write the width as a function of the length, thus:

[tex]2w = l - 3[/tex]

She uses 30 inches of framing material

This means that the perimeter is of 30 inches, that is:

[tex]2l + 2w = 30[/tex]

Since [tex]2w = l - 3[/tex]

[tex]2l + l - 3 = 30[/tex]

[tex]3l = 33[/tex]

[tex]l = \frac{33}{3}[/tex]

[tex]l = 11[/tex]

Thus, the length of the painting is of 11 inches.

Answer:

[tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=-1[/tex].

Step-by-step explanation:

Consider the given limit problem is

[tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=?[/tex]

We need to find the value of given limit problem.

Taking limit, we get

[tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=\dfrac{2(1)^2-9(1)+9}{(1)-3}[/tex]

[tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=\dfrac{2-9+9}{-2}[/tex]

[tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=\dfrac{2}{-2}[/tex]

[tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=-1[/tex]

Therefore, [tex]\lim_{x\to 1}\dfrac{2x^2-9x+9}{x-3}=-1[/tex].

The real numbers is one set, and so is the the set of integers since this set is { ..., -3, -2, -1, 0, 1, 2, 3, ...} composed of positive and negative whole numbers, along with 0.

The value -15 is also in the rational set because we can write it as a fraction of two integers:  -15 = -15/1

0

Step-by-step explanation:

-10r - 20 = -20

-10r = -20 + 20

Answer:

4/5 OR -4/5

Step-by-step explanation:

So, area of triangle = 1/2 * base * height

base = 5 (because x-axis is base, x-intercept is -5, so x-length = 5)

height is unknown

area = 10

We can form the equation: 1/2 * 5 * height = 10

Rearrange terms to get: height (y-height) = 10 / (0.5 * 5) = 4

Following the formula for gradient, dif in y / dif in x, we get 4/5

Therefore our gradient is (4/5), or 0.8.

But because we are only told the x-intercept, it can cross the y axis at y = 4 or y = -4. So there are actually 2 possible gradients, 4/5 and -4/5

A rectangle is a two - dimensional shape, so let me explain using it as an example.

The diagonal of a rectangle divides the rectangle into two triangles that are congruent (the same size and shape.)

Another example is parallelogram; the diagonal of a parallelogram also divides the figure into two separate shapes that are congruent.

Answer:

A. No, because the probability of success does not remain the same in all trials.

Step-by-step explanation:

In this procedure the number of televisions could vary in each house. Some people have one , two, even three or some may not have any. So the number of successes in each trial varies as the number of televisions varies.

Therefore, it is not a binomial distribution. It is necessary that for a binomial distribution the probability of success for each trial remains fixed.

Answer:

Step-by-step explanation:

h(x) = x² + 1

k(x) = x - 2

To find (h-k)(3) we must first find (h - k)(x)

To find (h - k)(x) subtract k(x) from h(x)

That's

(h - k)(x) = x² + 1 - ( x - 2)

(h - k)(x) = x² + 1 - x + 2

(h - k)(x) = x² - x + 1 + 2

We have

(h - k)(x) = x² - x + 3

To find (h-k)(3) substitute the value of x that's 3 into (h - k)(x) that's replace every x in (h - k)(x) by 3

We have

(h-k)(3) = (3)² - 3 + 3

= 9 - 3 + 3

= 9 - 0

We have the final answer as

Answer:

The cost of 1 ticket is 15 dollars

Step-by-step explanation:

The rate of change is another word for slope

m = (y2-y1)/(x2-x1)

    = (90-75)/(6-5)

   = 15/1

The cost of 1 ticket is 15 dollars

The rate of change is a ratio that compares the change in y/change in x.

We can see that the y-values increase by 15 each time and

we can see that the x-values increase by 1 each time.

So the change in y/change in x is 15/1.

This means that for every ticket bought, you pay $15.
