Answer:

P = x - 13

Yes, you will make a profit

Step-by-step explanation:

Given;

cost of making x cups, C = x + 25

predicted revenue, R = 12 + 2x

Profit of selling x cups is given by;

P = R - C

P = (12 + 2x) - (x + 25)

P = 12 + 2x - x - 25

P = x - 13

When 20 cups of  lemonade are sold, the profit made can be estimated using the profit function above;

P = x - 13

P = 20 - 13

P = 7

Thus, you will make a profit

Answer: Option D

Step-by-step explanation:

Hey there!

Here; Looking at it we can state that it is a Right angled triangle.

And must use the Pythagoras relation if the triangle is a Right angled triangle.

So, let's work on it.

Let ABC be a triangle.

Taking reference angle as C, we get;

perpendicular= 3m

Hypotenuse= 7m

Base = xm

Now;

[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]

[tex]or \: b = \sqrt{ {h}^{2} - {p}^{2} } [/tex]

Put all values.

[tex]b = \sqrt{ {7}^{2} - {3}^{2} } [/tex]

Simplify to get answer.

[tex]b = \sqrt{49 - 9} [/tex]

[tex]b = \sqrt{40} [/tex]

Therefore, X= 6.3m.

Hope it helps...

Answer:

68mph to 134 mph

Step-by-step explanation:

We apply

Chebyshev's Theorem States:

At least 3/4 or 75% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question,

Mean = 101 miles per hour

Standard deviation = 11 miles per hour

We are to give an interval that will contain the speeds of at least eight ninths of the players serves

Hence, we apply the rule

At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

μ - 3σ

= 101 - 3(11)

= 101 - 33

= 68 miles per hour

μ + 3σ.

= 101 + 3(11)

= 101 + 33

= 134 miles per hour

Therefore, the interval is 68mph to 134 mph

Answer:

Step-by-step explanation:

Look a the picture.

Draw the horizontal line y = 2.

Common point: (-4, 2).

Conclusion: f(x) = 2 → x = -4

From the graph at x = -4, then value of f(x) will be 2.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

In the given graph, first we have to draw a line f(x)=2 i.e y=2

Draw the horizontal line y = 2.

We have to check where the horizontal line is meeting the line in graph.

Then we get a Common point at (-4, 2).

So x value is =-4 for f(x)=2 in the given graph.

We have x = 4 repeating itself

If we graph the two points (4,1) and (4,20), then we see the relation fails the vertical line test.

The input x = 4 leads to more than one output y = 1 and y = 20 simultaneously.

This is why we don't have a function.

The given set does not represent the function as one value of [x] has two values of [y] in the coordinates -

(4, 1), (4, 20).

Given are the coordinates as -

{(1, 5), (2, 6), (3, 6), (4, 1), (4, 20), (5, 21), (6, 24)}

The given set does not represent the function as one value of [x] has two values of [y] in the coordinates -

(4, 1), (4, 20).

Therefore, the given set does not represent the function as one value of [x] has two values of [y] in the coordinates -

(4, 1), (4, 20).

Answer:amount of decrease 290 ;numbers of chairs 5510

Step-by-step explanation:

Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Number of chairs produce in a month = 5800

5% decrease in production:

= 5% of 5800

= 5/100 x 5800

= 5 x 58

= 290

The number of new chairs produced each month:

= 5800 - 290

= 5510

Thus,

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.

4x – 2y=7

3x – 3y = 15

we want to keep y by eliminating the x

so we will Multiply the top equation by 3 and the bottom equation by 4.

we will get

12x - 6y = 21

12x - 12y = 60

we subtract the equations

12x - 6y - 12x - (-12y) = 21 - 60

6y = -39 and so on

Answer:

29.92 m² (nearest hundredth)

Step-by-step explanation:

[tex]\textsf{Area of a sector}=\dfrac{\theta}{360\textdegree}\pi r^2[/tex]

[tex]\implies \textsf{area}=\dfrac{30}{360\textdegree}\pi \cdot 5.5^2=\dfrac{121}{48}\pi \textsf{ m}^2[/tex]

Area of rectangle = width × length

⇒ area = 4 × 5.5 = 22 m²

Total area = area of sector + area of rectangle

⇒ total area = [tex]\dfrac{121}{48}\pi +22[/tex] = 29.91943148... = 29.92 m² (nearest hundredth)
