Identify the tables that represent the relative frequencies of this data by rows or by columns. Round your answers to the nearest hundredth.
Answer:
the middle left and right
The table representing the relative frequencies by rows would be:
King Bed Queen Bed
Mountain 0.58 0.42
Ocean 0.38 0.62
The table representing the relative frequencies by columns would be:
King Bed Queen Bed

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.

Deon is playing fetch with his dog with a toy that is shaped like a circle. The circumference of the toy is 12π inches.
Which measurement is closest to the area of the toy in square inches?
18.84 in.²
37.68 in.²
113.04 in.²
452.16 in.²
Answer:
113.04
Step-by-step explanation:
The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex]
Given that,
Deon is playing fetch with his dog with a toy that is shaped like a circle,
The circumference of the sculpture is 12π inches.
We have to determine,
Which measurement is closest to the area of the toy in square inches.
According to the question,
Circumference of the circle = [tex]2\pi r[/tex]
Where, circumference = [tex]12\pi[/tex]
Then,
[tex]12\pi =2\pi r \\\\r = \dfrac{12\pi }{2\pi }\\\\r = 6\ inches[/tex]
Therefore,
Deon is playing fetch with his dog with a toy that is shaped like a circle.
Area of the circle = [tex]\pi r^{2}[/tex]
Where, r = 6inches
Then,
Area of the circle is given by,
[tex]= \pi r ^{2}\\\\= 3.14 \times (6)^{2}\\\\= 3.14 \times 36\\\\= 113.04\ inches^{2}[/tex]
Hence, The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex].

A steel ball is dropped from a height and hits the ground 6.7 seconds after its release. From what height (in feet) was the ball released?
Step-by-step explanation:
Acceleration = g = 32.17ft/s²
Initial velocity = 0ft/s
Time taken = 6.7s
Using Kinematics,
we have s = ut + 0.5at².
=> s = (0)(6.7) + 0.5(32.17)(6.7)²
=> s = 722.06ft.

Answer: D.) y = 2x + 1
Step-by-step explanation:
in slope-intercept form, y = mx + b, m is the slope, Rise/Run
The difference in y-values, rise, increases by 2 for every increase of 1 in x-values, the run.
2/1 is the slope
m = 2
b is the y-intercept
To calculate b, substitute any pair of y and x values from the chart, and the value 2 for m:
9 = 4(2) + b
9 = 8 + b
1 = b
Rewrite the equation with the values calculated for m and b. Keep y and x
y = 2x + 1
In the following equation, what is the y-intercept? y = -3.1 +7 03 o7
Answer:
the y-intercept, b, is 7
Step-by-step explanation:
Compare the given y = -3.1 +7 to y = mx + b. I must assume that you meant
y = -3.1x +7. It becomes evident that the slope, m, is -3.1 and the y-intercept, b, is 7.

Answer and Step-by-step explanation:
Hello!
You are told to round the number to the nearest whole number.
That means if the decimal is lower than 5 in the tenths place, the number would round down, and if the decimal is equal to or higher than 5 in the tenths place, the number would round up.
[tex]5\frac{5}{6}[/tex] is equal to 5.833. The number 8 is greater than 5, so the number rounds up to 6.
[tex]6\frac{1}{9}[/tex] is equal to 6.111. The number 1 is less than 5, so the number rounds down to 6.
Now we have the equation n - 6 = 6.
We solve for n.
Add 6 to both sides.
n = 12
n is equal to 12.
