A mountain lodge charges a weekly cabin rental fee of $450 for a single guest, plus $125
for each additional guest.
Which of these equations models the relationship between the number of guests, x, and
the total charge, y?
A. y = 450 + 125x
B. y = 450+ 125(x - 1)
C. y = 450+ (125 - 1)x
D. y = (450-x) + 125
Answers
The equation that models the relationship between the number of guests, x, and the total charge, y is A. y = 450 + 125x. The base charge for a single guest is $450, and for each additional guest, the charge increases by $125. So, we add 125 times the number of additional guests to the base charge of $450.

The surface area of the cube is equal to 216 cm².

\(\displaystyle \text{SA} = 6a^2\)
Step-by-step explanation:
Step 1: Define
Identify given variables.
a = 6 cm
Step 2: Find Surface Area
[Surface Area Formula - Cube] Substitute in a:\(\displaystyle \text{SA} = 6(6 \ \text{cm})^2\)Evaluate:
\(\displaystyle \text{SA} = \boxed{216 \ \text{cm}^2}\)
∴ we have found the surface area of the cube to be 216 cm².
---
Topic: Geometry
The surface area of a 3D figure is the sum of the area of its faces.
We know the following:
As this shape is a cube, all faces of a cube must be a square. The area of a square is known as (side)².All faces in a cube must have the same areaThere are 6 faces in a cubeSince all faces in a cube have the same area, the surface area of a cube is:
\(\boxed{(\text{side})^{2} + (\text{side})^{2} + (\text{side})^{2} + (\text{side})^{2} + (\text{side})^{2} + (\text{side})x^{2} = 6(\text{side})^{2}}\)
Therefore, the surface area of a cube must be known as 6(side)².
Part II: Determining the surface area of the cube\({\text{Given side length of cube:} \ |\text{6 centimeters}|\)
Substitute the side length in the surface area formula and simplify:
\(\implies 6(6)^{2}\)
\(\implies 6(6)(6)\)
\(\implies \boxed{216 \ \text{cm}^{2}}\)
Therefore, the surface area of the cube is 216 cm².

A class with n kids lines up for recess. The order in which the kids line up is random with each ordering being equally likely. There are two kids in the class named Celia and Felicity. Give an expression for each of the probabilities below as a function of n. Simplify your final expression as much as possible so that your answer does not include any expressions of the form (). (a) What is the probability that Celia is first in line? (b) What is the probability that Celia is first in line and Felicity is last in line? (C) What is the probability that Celia and Felicity are next to each other in the line? Feedback?
Answers
P = 1 / n (Celia is first and Felicity is last in line) (n - 1)
P (in the line, Celia and Felicity are next to one another) = 2/n
A class consists of n kids.
These n kids line up for recess.
Out of n kids, there are two kids named Celia and Felicity.
(b) There are n positions and n! ways for n youngsters to stand in a line.
Consequently, n is the entire number of possible situations!
Felicity is standing in the last position while Celia is in the first (fixed position)
The remaining (n - 2) children can stand in the remaining 8 (n - 2) positions! ways
As a result, Celia is first in line and Felicity is last in line for the number of favorable situations, which is (n - 2)!
P (Celia is first in line and Felicity is last in line) = [(n - 2)! / n!]
P = (n - 2)! / [n(n - 1)(n - 2)!]
P = 1 / n(n - 1)
The likelihood that Celia and Felicity are on the same row as one another.
Consider Celia and Felicity as a single student, then multiply by the number of pupils (n - 1)
One can arrange (n - 1) pupils in (n - 1) positions! ways
However, there are two methods to organize Celia and Felicity among themselves.
There are therefore 2 good reasons to put Celia and Felicity adjacent to each other (n - 1)!
P(Celia and Felicity in the line are next to one another) = 2! * (n - 1)! / n!
P = 2 * (n - 1)! / n (n - 1)
P = 2/n

Billy took 5 tests in his math class. He scored an 89,88,93,90 and 81. What is the variance of his grades in these test? If necessary, round to the nearest hundredth.
Answers
The variance of Billy's grades obtained from his test scores is 15.76
What is variance?The variance is a measure of variability or spread a dataset. The variance can be calculated from the sum of the square of the differences of the data points from the mean divided by the number or count of the data points.
The variance of Billy's test scores can be calculated by finding the mean or the average of the scores, then finding the sum of the squares of the differences of each score from the mean as follows;
The mean score = (89 + 88 + 93 + 90 + 81)/5 = 88.2
The square of the differences of the values from the mean can be calculated as follows;
(89 - 88.2)² = 0.64, (88 - 88.2)² = 0.04, (93 - 88.2)² = 23.04, (90 - 88.2)² = 3.24, and (81 - 88.2)² = 51.84
The sum of the square of the differences is therefore;
0.64 + 0.04 + 23.04 + 3.24 + 51.84 = 78.8
The variance is therefore; 78.8/5 = 15.76Learn more on the variance of a set of data here: https://brainly.com/question/30701163
