Based on the mean from the sample, I would expect that the number of guests that will stay at the small hotel than at the bed and breakfast would be 4.50.

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

The number of guests at the small hotel in excess of those at the bed and breakfast = 7.75 - 3.25 = 4.50

Answer:

315 more guests will stay at the small hotel than at the bed and breakfast in a 10-week period.

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

At the small hotel, a mean of 7.75 guest stay per night. 10 weeks have 70 days, then the total amount is:

S = 7.75 x 70 = 542.5

At the bed and breakfast, the mean was of 3.25 guests per night, hence:

B = 3.25 x 70 = 227.5.

The difference is given by:

S - B = 542.5 - 227.5 = 315.

Therefore, 315 more guests will stay at the small hotel than at the bed and breakfast in a 10-week period.

108/8=13.5

13x8=104

108-104=4

Answer:

3.5

Step-by-step explanation:

Set up the Pythagorean Theorem (a^2 + b^2 = c^2) where the unknown side is x:

2^2 + x^2 = 4^2

4 + x^2 = 16

x^2 = 12

x = ± sqrt(12)

x ≈ 3.5

Note: '^' means "to the power of", so '^2' means "squared"

Answer:

or, x^2-14x-51=0

or, x^2-(17-3)x-51=0

or, x^2-17x+3x-51=0

or, x(x-17)+3(x-17)=0

or, (x-17)(x+3)=0

Either, x-17=0. Or, x+3=0

x=17. x= -3

Hence,x=17, -3

[tex]x^2-51=14x\\\\\implies x^2-14x = 51\\\\\implies x^2 -2\cdot 7\cdot x+7^2-7^2 =51\\ \\\implies x^2 -2\cdot 7 \cdot x +7^2 = 51 +49\\\\\implies (x-7)^2=100\\\\\implies x-7 = \pm\sqrt{100}\\\\\implies x =\pm10+7\\ \\\text{Hence,}~ x=17, ~x=-3[/tex]

y=4

x=-5

Step-by-step explanation:

-4(2y-13) + 5y = 40

Answer:

47

Step-by-step explanation:

To find the mean, you sum all the numbers, then count the number of numbers you summed up (amount of numbers in the array which in this case is 8) and then divide the two. So you get

Σarray/arraysize = 75+14+48... / 8

Answer:

Mean = 47

Step-by-step explanation:

Given terms :

The mean is equal to the sum of the terms divided by the number of terms.

Therefore, the mean is equal to :

2 feet.

how many square feet of wood he used to build the box.

each side measures 2ft.

A=L²=(2 ft)²=4 ft²

A cube has 6 sides so the total quantity of wood is:

Wood=6×A

=6×4 ft²

=24 ft²

he used 24 ft² of wood to build the box.

Answer:

(- 6, 0 )

Step-by-step explanation:

x = -2y - 6 → (1)

- 3x - 7y = 18 → (2)

substitute x = - 2y - 6 into (2)

- 3(- 2y - 6) - 7y = 18 ← distribute parenthesis and simplify left side

6y + 18 - 7y = 18

- y + 18 = 18 ( subtract 18 from both sides )

- y = 0 , then

y = 0

substitute y = 0 into (1)

x = - 2(0) - 6 = 0 - 6 = - 6

solution is (- 6, 0 )

Answer:

  (x, y) = (-6, 0)

Step-by-step explanation:

A system of equations is easily solved using a graphing calculator. The attached shows the solution to be ...

  (x, y) = (-6, 0)

__

The first equation gives a convenient expression for substituting for x in the second equation:

  -3(-2y -6) -7y = 18

  18 -y = 18 . . . . . . . . simplify

  y = 0 . . . . . . . . add y-18

  x = -2(0) -6 = -6

The solution by substitution is (x, y) = (-6, 0).

Answer:

180°

Step-by-step explanation:

The Angle of Rotational Symmetry is the degree of rotation required to make the shape look like the original.

If you rotate it once by 90°, it will look completely different.

However, if you rotate it again by 90°, it looks identical to the original.

90° + 90° = 180°

Answer:

That would be (2, infinite)

Answer:

a. f = 72/p

b. 14.4

Step-by-step explanation:

a. bringing in constant k,

f = k/p

cross multiplying

k = fp

k = 8×9

k = 72

the formula for f;

f = 72/p

b. Using the formula for f

f = 72/p

f = 72/5

f = 14.4

Hello!!

You must cancel out the common factor or in this case, ( a3/2) on the top.

You will now have ( 3/2) which should then be simplified to ( 1 1/2) or in this case ( A- 1/2)

Answer:

Step-by-step explanation:

a) x be the height of the wall

[tex]tan \ 14 =\dfrac{opposite \ side}{adjacent \ side}\\\\\\0.2493 = \dfrac{3}{x}\\\\\\x*0.25 = 3\\\\x = \dfrac{3}{0.25}\\\\\\x = 12 ft[/tex]

b) Let y be the hieght of  the wall

[tex]Sin \ 75 = \dfrac{opposite \ side}{hypotenuse}\\\\\\0.9659 = \dfrac{y}{15}\\\\\\0.97*15=y\\\\[/tex]

y = 14.6 ft

c) Let the angle formed between the bottom of the ladder to the ground be 'x'

[tex]Cos \x =\dfrac{adjacent \side}{hypotenuse}\\\\Cos \ x =\dfrac{3}{20}\\\\\\Cos \x = 0.15\\\\x = Cos^{-1} \ (0.15)\\\\[/tex]

x = 81°

No, the angle formed between the ground and the ladder is not safe as it is more than 70°

Let the farthest possible distance ladder placed from the wall be 'y'

[tex]Cos \ 70 =\dfrac{adjacent \ side }{hypotenuse}\\\\0.342 = \dfrac{y}{20}\\\\0.3*20=y[/tex]

y = 6 ft

6 ft is the furthest possible distance the ladder can be placed to maintain a safe angle.

Answer:

x = 28

Step-by-step explanation:

4x-16 = 2(x+20)

4x-16 = 2x+40

Divide 2x from each side:

2x-16 = 40

Add 16 to each side:

2x = 56

Divide each side by 2:

x = 28

Answer:

y=3x

Step-by-step explanation:

Okay first you need to solve this. Distribute the 3 first to the parantheses and you get y+3=3x+3. Than you subtract 3 and get y=3x. Now you start at 0,0 the origin and go 3 units up and 1 unit to the right. Continue that until a line shows.  Same with the bottom. Go down 3 left one.
