Step-by-step explanation:

Answer:

The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600

Step-by-step explanation:

Given

[tex]Rooms = 240[/tex]

[tex]Price= \$40[/tex]

[tex]Increment = \$2[/tex]

First, we calculate the revenue.

[tex]Revenue (r) = Price (p) * Number\ of\ Rooms(n)[/tex]

[tex]r = p*n[/tex]

Let x be the change in rate.

i.e.

For every 2x increment in price (p) i.e. p + 2x

There will be 4 fewer rooms (n) i.e. n - 4x

So, the revenue is updated as:

[tex]r = (p + 2x) * (n - 4x)[/tex]

[tex]Price = 40[/tex]

So:

[tex]r = (40 + 2x) * (n - 4x)[/tex]

[tex]Rooms = 240[/tex]

So:

[tex]r = (40 + 2x) * (240 - 4x)[/tex]

Expand

[tex]r = 40 * 240 - 40 * 4x + 2x * 240 - 2x*4x[/tex]

[tex]r = 9600 - 160x + 480x - 8x^2[/tex]

Reorder

[tex]r = -8x^2 - 160x + 480x + 9600[/tex]

[tex]r = -8x^2 +320x + 9600[/tex]

The maximum of a function is calculated as:

[tex]Max = -\frac{b}{2a}[/tex]

In: [tex]r = -8x^2 +320x + 9600[/tex]

[tex]a = -8[/tex]   [tex]b = 320[/tex]    [tex]c = 9600[/tex]

So:

[tex]Max = -\frac{b}{2a}[/tex]

[tex]Max = -\frac{320}{-8}[/tex]

[tex]Max = \frac{320}{8}[/tex]

[tex]Max = 40[/tex]

To get the maximum revenue;

Substitute 40 for x in [tex]r = -8x^2 +320x + 9600[/tex]

[tex]r = -8(40)^2 + 320 * 40 + 9600[/tex]

[tex]r = 9600[/tex]

The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600

Answer:

The correct option is (A). The first equation is for sample​ data; the second equation is for a population.

Step-by-step explanation:

According to the scenario, the following would be represented as a sample and the population

Y with caret = b0 + b1x = sample

and

y = b0 + b1x =  population

It is because if we considered the population than the expected value would be nearest and there is no need to determine the b0 and b1 value again. But in the case of the sample, the reestimation of the values would be determined again and again

Therefore the correct option is A.

The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).

In this question we know the locations of the four vertices of the trapezoid RSTV and we need to determine the coordinates of its image by using a reflection formula about an axis parallel to the y-axis, whose formula is described below:

P'(x, y) = P(x, y) - 2 · [P(x, y) - (p, k)]    

Where:

Now we proceed to find the coordinates of the images:

R'(x, y) = (- 1, 1) - 2 · [(- 1, 1) - (- 1, - 3)]

R'(x, y) = (- 1, 1) - 2 · (0, 4)

R'(x, y) = (- 1, 1) + (0, - 8)

R'(x, y) = (- 1, - 7)

S'(x, y) = (4, 1) - 2 · [(4, 1) - (4, - 3)]

S'(x, y) = (4, 1) - 2 · (0, 4)

S'(x, y) = (4, 1) + (0, - 8)

S'(x, y) = (4, - 7)

T'(x, y) = (4, - 1) - 2 · [(4, - 1) - (4, - 3)]

T'(x, y) = (4, - 1) - 2 · (0, 2)

T'(x, y) = (4, - 1) + (0, - 4)

T'(x, y) = (4, - 5)

V'(x, y) = (- 1, - 3) - 2 · [(- 1, - 3) - (- 1, - 3)]

V'(x, y) = (- 1, - 3) - 2 · (0, 0)

V'(x, y) = (- 1, - 3)

The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).

Answer:

why the hell you got blobs in your bed?

Step-by-step explanation:

The equation of line that passes through the given points is x-5y=47.

Given that the line that passes through ( -3,-10) and (7,-8).

The standard form of the line equation is ax+by+c = 0. Here a, b are the coefficients, x, y are the variables and c are the constant terms. It is a quadratic equation, of the variables x and y. The values ​​of x and y represent the coordinates of the point on the line in the coordinate plane.

Firstly, we will find the slope of equation of line by using the given points.

(x₁,y₁)=(-3,-10) and (x₂,y₂)=(7,-8).

m=(y₂-y₁)/(x₂-x₁)

Now, we substitute the values, we get

m=(-8-(-10))/(7-(-3))

m=(-8+10)/(7+3)

m=2/10

m=1/5

Further, we will find the equation of line using the formula y-y₁=m(x-x₁).

Now, we will substitute the values , we get

y-(-10)=(1/5)(x-(-3))

y+10=(1/5)(x+3)

Further, we will multiply both sides by 5, we get

5(y+10)=x+3

5y+50=x+3

5y+50-50=x+3-50

5y=x-47

x-5y=47

Hence, the equation of line that passes through ( -3,-10) and (7,-8) is x-5y=47.

Answer:

c. C

Step-by-step explanation:

byy byyy..........

This portion of the graph is completely flat, and has a slope of 0. The slope is the rate of change. Any horizontal line has a slope of 0 (we can use the slope formula to prove this). The term 'constant" means "it does not change".

In contrast, sections A, B, and D are all increasing sections because they go uphill as we move from left to right. The slopes of each line segment are positive.

Answer:

[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1

Step-by-step explanation:

Required

Which is undefined at a = 1

An expression is undefined when its denonimator equals 0.

So, we have to test the denominator of each.

(A): 7a + 7

This gives:

[tex]= 7(1) + 7[/tex]

[tex]= 7 + 7[/tex]

[tex]= 14[/tex]

(B): 5a - 10

This gives:

[tex]= 5(1) - 10[/tex]

[tex]= 5- 10[/tex]

[tex]= -5[/tex]

(C) -a² + 1

This gives

[tex]-(1^2) + 1[/tex]

[tex]= -1 + 1[/tex]

[tex]=0[/tex]

(D) 3a²

This gives:

[tex]= 3(1)^2[/tex]

[tex]= 3 * 1[/tex]

[tex]= 3[/tex]

Notice that only (C) equals 0.

Hence:

[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1

Answer:

C

Step-by-step explanation:

The simplified trigonometric expression is given as follows:

[tex]-sin{\theta}\tan{\theta}(1 - \csc{\theta})[/tex]

The expression is given by:

[tex]\frac{\cos{\theta}}{1 + \csc{\theta}} \times \frac{1 - \csc{\theta}}{1 - \csc{\theta}}[/tex]

Applying the subtraction of perfect squares at the denominator, we have that the expression is given by:

[tex]\frac{\cos{\theta}(1 - \csc{\theta})}{1 - \csc^2{\theta}}[/tex]

Applying an identity, we have that:

[tex]1 - \csc^2{\theta} = -\cot^2{\theta}[/tex]

Hence the expression is:

[tex]-\frac{\cos{\theta}(1 - \csc{\theta})}{\cot^2{\theta}}[/tex]

cot = cos/sin, hence:

[tex]-\frac{sin^2{\theta}(1 - \csc{\theta})}{\cos{\theta}}[/tex]

tan = sin/cos, hence the simplified expression is:

[tex]-sin{\theta}\tan{\theta}(1 - \csc{\theta})[/tex]

The increased percent and decreased percent of an item are not equal.

What is Percent formula?

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

Now,

Let the original price of an item = $100

After increased by $10,

Increased percent of an item = 10 * 10/100 = 10%

The new cost of an item = $100 + $10 = $110

After decreased by $10,

Decreased percent of an item = 10 * 10/110 = 9.1%

So, The increased percent and decreased percent of an item are not equal.

Answer:

[tex]\dfrac{2}{3}[/tex]

Step-by-step explanation:

Given that:

The number of observations is:

6, 10, 12

If we are to use a simple  random sampling without replacement, then we will have:

(6,10)  (6,12)  (10,12)

Here;

the sample size n = 2

The population size N = 3

For (6,10) ; The sample mean = [tex]\dfrac{6+10}{2}[/tex]

= [tex]\dfrac{16}{2}[/tex]

= 8

For (6,12) ; The sample mean = [tex]\dfrac{6+12}{2}[/tex]

= [tex]\dfrac{18}{2}[/tex]

= 9

For (10, 12) ; The sample mean = [tex]\dfrac{10+12}{2}[/tex]

= [tex]\dfrac{22}{2}[/tex]

= 11

The probability distribution of sample mean(x) is:

X           8           9          11

P(X=x)    [tex]\dfrac{1}{3}[/tex]          [tex]\dfrac{1}{3}[/tex]           [tex]\dfrac{1}{3}[/tex]

Thus, the probability that the sample mean  is larger than 8 is:

P(X> 8) = P(X = 9) + P(X + 11)

P(X> 8) = [tex]\dfrac{1}{3}+\dfrac{1}{3}[/tex]

P(X > 8) = [tex]\dfrac{1+1}{3}[/tex]

P(X> 8) = [tex]\dfrac{2}{3}[/tex]

Explanation:

The mean of all ten numbers is 22.

This tells us the sum of those ten numbers is 10*22 = 220

Recall that

mean = (sum of items)/(number of items)

We take this process in reverse to find the sum.

In other words:

sum = (mean)*(number of items)

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

Now remove the elements {8,12,21,23} to get a new sum of:

220-8-12-21-23 = 156

Divide that smaller sum over 6 since removing 4 elements leaves us with 10-4 = 6 left over.

new mean = (new smaller sum)/(number of items)

new mean = (156)/(6)

new mean = 26
