What is a relative frequency?Relative frequency is a statistical term that describes the proportion or percentage of times that an event or value occurs within a dataset or sample.
It is calculated by dividing the number of times the event occurs by the total number of observations in the dataset or sample.
We have,
To find the relative frequencies of this data by rows or by columns, we need to divide each count by the total number of rooms occupied. The total number of rooms occupied is:
25 + 18 + 12 + 20 = 75
To find the relative frequencies by rows, we divide each count by the total for that row:
For Mountain View rooms:
King Bed: 25/(25+18) ≈ 0.58
Queen Bed: 18/(25+18) ≈ 0.42
For Ocean View rooms:
King Bed: 12/(12+20) ≈ 0.38
Queen Bed: 20/(12+20) ≈ 0.62
The table representing the relative frequencies by rows would be:
King Bed Queen Bed
Mountain 0.58 0.42
Ocean 0.38 0.62
To find the relative frequencies by columns, we divide each count by the total for that column:
For King Bedrooms:
Mountain View: 25/(25+12) ≈ 0.68
Ocean View: 12/(12+20) ≈ 0.38
For Queen Bedrooms:
Mountain View: 18/(18+20) ≈ 0.47
Ocean View: 20/(18+20) ≈ 0.53
The table representing the relative frequencies by columns would be:
King Bed Queen Bed
Mountain 0.68 0.47
Ocean 0.32 0.53
Note that we round the relative frequencies to the nearest hundredth.
Thus,
The table representing the relative frequencies by rows and columns is given above.

tan 235° = 2tan20°+ tan215°
Answers
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215

I'll help you with this so reflections is not hard.
For reflect over x-axis you need to switch the sign on Y. formula for points like this is (x,y). An example is reflect (2,4) over the x-axis. you just change the sign of y making the answer (2,-4).
For reflect over y-axis you change the sign of X.For example reflect over the y-axis (3,7) all you have to do is change the sign of X which leaves you with the answer of (-3,7).
sign is basically + or - if need to know.

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Answers
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

A random sample of Maxwell High School students showed that 7 out of every 12 students ride the bus to school . Maxwell High School has a total of 840 students . Based on the sample , how many students most likely ride the bus to school ?
Plsss fast
Answers
We would expect about 490 students to ride the bus to school based on the sample
What is random sampling?It is the way of choosing a number of required items from a population given.
Each item has an equal probability of being chosen.
We have,
If 7 out of every 12 students ride the bus to school, then the proportion of students who ride the bus is 7/12 or approximately 0.5833.
If we assume that this proportion holds true for the entire school, then we can estimate the number of students who ride the bus as follows:
Number of students who ride the bus = Proportion who ride the bus x Total number of students
Number of students who ride the bus = 0.5833 x 840
Number of students who ride the bus = 489.99
Since we cannot have a fractional number of students, we would round this estimate to the nearest whole number.
Thus,
We would expect about 490 students to ride the bus to school based on the sample
