x=5
y=52


since AB and BC are the same length, you know it is an isosceles triangle
so two of the angles are the same
angle A and angle C are the same
so y = 52
A = C :. y = 52


all angles of a triangle add to 180
so add 52 and 52 to get 104
subtract 104 from 180 to get 76
set 14x + 6 = 76
14x = 70
x = 5

The average hotel price in Moscow is $216 per night with a standard deviation of $32. The average hotel price in Cancun is $161 per night with a standard deviation of $22. The average hotel price in Bangkok is $100 per night with a standard deviation of $17. A room at the Emerald Hotel in Moscow costs $200 per night, a room at the Ocean View Hotel in Cancun costs $183 per night, and a room at the Emperor Hotel in Bangkok costs $120 per night.

Required:
Which hotel is more expensive compared to other hotels in its city?

Answers

Answer:

The Emperor Hotel in Bangkok has the higher z-score, so it is more expensive compared to other hotels in its city.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

The most expensive hotel has the higher z-score. So

Emerald Hotel in Moscow:

Costs $200, which means that [tex]X = 200[/tex]

The average hotel price in Moscow is $216 per night with a standard deviation of $32, which means that [tex]\mu = 216, \sigma = 32[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{200 - 216}{32}[/tex]

[tex]Z = -0.5[/tex]

Ocean View Hotel in Cancun

Costs $183, which means that [tex]X = 183[/tex].

The average hotel price in Cancun is $161 per night with a standard deviation of $22, which means that [tex]\mu = 161, \sigma = 22[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{183 - 161}{22}[/tex]

[tex]Z = 1[/tex]

Emperor Hotel in Bangkok

Costs $120, which means that [tex]X = 120[/tex].

The average hotel price in Bangkok is $100 per night with a standard deviation of $17, which means that [tex]\mu = 100, \sigma = 17[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{120 - 100}{17}[/tex]

[tex]Z = 1.18[/tex]

The Emperor Hotel in Bangkok has the higher z-score, so it is more expensive compared to other hotels in its city.

4-3/1-0= 1/1= 1

Also when you graph it, it does not become a line. I can attach an image for evidence (Credits to other person who answered and commented on my answer thanks for finding my mistake.)

The second one has an exponent on the x, so it is not linear.

The complete factorization of the given polynomial is 2(x-5)(x+1)(x-1).

The given polynomial is 2x³-10x²-2x+10.

What are factors of polynomial?

The factors are the polynomials which are multiplied to produce the original polynomial.

The factorization of the given polynomial is as follows:

2x³-10x²-2x+10

= 2x²(x-5)-2(x-5)

= (x-5)(2x²-2)

= 2(x-5)(x²-1)

Now, x²-1=(x+1)(x-1) (∵(a²-b²=(a+b)(a-b))

So, 2(x-5)(x+1)(x-1)

Therefore, the complete factorization of the given polynomial is 2(x-5)(x+1)(x-1).

Answer:check explanation below

Step-by-step explanation:

Okay so for Part A: since B is the midpoint of SM, SM=SB+BM. Therefore, you can set them both equal to each other which would be 4x=98.3. You divide both sides by 4 to get the value of x which is 24.575. Now you substitute 24.575 back into 4x and you get 98.3. Since SM=SB+BM, you do 98.3+98.3 and SM=196.6.

Part B: For part b you do the same thing as A to find the values of x y and x. You already know that x=24.575. For Y, since T is the midpoint of DS you can set ST=TD. This means that 123.4=2/5y. When you solve for y you get y=308.5. Lastly, for z since N is the midpoint of MD, MN=ND. So 102=7/10z. When you solve for z you get approximately 145.7. Now you just add them together -- 24.575+308.5+145.7= 478.775.

Part C: NT is half of SM. Since SM is 196.6, NT is 98.3. TB is half of MD. MD is 203.99 so TB is 101.995. BN is half of SD. SD is 246.8 so BN is 123.4

So, NT+TB-BN is 98.3+101.995-123.4 which equals 76.895
