Relative frequency distributions are generally more useful than frequency distributions when comparing data sets of different sizes.
Frequency distributions can show the actual number of observations falling in each range or the percentage of observations. In the latter sample, the distribution is called a relative frequency distribution.
Frequency distribution tables can be utilised for both categorical and numeric variables. Continuous variables should only be used with class intervals, which will be described shortly.
A relative frequency distribution displays the proportion of the total number of observations associated with each value or class of values and is related to a probability distribution, which is extensively used in statistics.

Given that the reflex angle at G is x degrees, then x is equal to
What is a reflex angle?A reflex angle is a type whose value falls within 180^o and 360^o. This implies that the value of the angle is greater than 180^o, but less than 360^o.
Considering the reflex angle given in the question, it can be deduced that;
m<AGE + m<GAE + m<GEA = 180^o
But,
i. m<GAB + m<GAE = 180^o (sum of angles on a straight line)
120 + m<GAE = 180
m<GAE = 180 - 120
= 60
m<GAE = 60^o
ii. m<GEA + m<GEL = 180^o
m<GEA + 80 = 180
m<GEA = 180 - 80
= 100
m<GEA = 100^o
Thus,
m<AGE + m<GAE + m<GEA = 180^o
m<AGE + 100 + 60 = 180
m<AGE = 180 - 160
= 20
m<AGE = 20^o
Therefore,
x + m<AGE = 360 (sum of angles at a point)
x + 20 = 360
x = 360 - 20
= 340
x = 340^o
x is equal to 340^o.

solve. 10) what are the dimensions of a right triangle with a 5 inch hypotenuse and an area of 6 square inches?
Answer:
The dimensions are 3, 4 and 5 inches.
Step-by-step explanation:
Area = 1/2 * height * base
6 = 1/2 * h * b
h * b = 12.
As the hypotenuse is 5 inches long
H^2 + B^2 = 5^2
From the third line: h = 12/b, so we have
(12/b)^2 + b^2 = 25
144/b^2 + b^2 = 25
144 + b^4 = 25b^2
b^4 - 25b^2 + 144 = 0
Let B = b^2, so
B^2 - 25B + 144 = 0
(B - 16)(B - 9) = 0
B = 16, 9
So, b = 4, 3
h = 12/b
= 3 , 4.

The probability that Sam's first upgrade will occur after the third flight = 0.729
Let m represents the number of flights Sam must take in order to receive his first upgrade.
To find the probability that Sam's first upgrade will occur after the third flight.
i.e., to find P(m ≥ 4)
Here, 0.10 probability that a coach-class ticket holder who flies frequently will be upgraded to first class on any flight.
p = 0.10
q = 1 - p
q = 0.90
P(m ≥ 4) = 1 - P(m ≤ 3)
P(m ≥ 4) = 1 - [P(m = 1) + P(m = 2) + P(m = 3)]
P(m ≥ 4) = 1 - [0.1 + (0.9 × 0.1) + (0.9² × 0.1)]
P(m ≥ 4) = 1 - (0.1 + 0.09 + 0.081)
P(m ≥ 4) = 0.729

The interpret of P(0) is 0 and P(250) = 132.58. The domain of P is [0, ∞]
The population of Sasquatch in Portage County can be modeled by the function P(t) = 140t/(t + 14) where t represents the number of years since 1803.
We have to interpret P(0).
To interpret P(0) we put t = 0 in the function then solve the function.
The function is:
P(t) = 140t/(t + 14)
Putting t = 0
P(0) = (140 × 0)/(0 + 14)
P(0) = 0/14
P(0) = 0
Now we interpret P(250) by putting t = 250.
P(250) = (140 × 250)/(250 + 14)
P(250) = 35,000/264
P(250) = 132.58
The domain of the time cannot be negative. So the domain of P is [0, ∞].

There are 50 bacteria present initially in a culture. In 3min., the count is 204800.
What is the doubling period?
Answer: The doubling period is the time it takes for the population of bacteria to double. To find the doubling period in this case, we need to determine how often the population doubles during the 3-minute period.
We know that the initial population is 50 and the final population is 204800, which means that the population has grown by a factor of 204800/50 = 4096. Since this is a multiplication by a factor of 4096, this means that the population has doubled 4096 times in 3 minutes.
To find the doubling period, we need to divide the total time (3 minutes) by the number of doublings (4096).
So, the doubling period is:
3 minutes / 4096 = 3/4096 minutes ≈ 0.0007 minutes ≈ 0.042 seconds
So, the population of bacteria doubles every 0.042 seconds

The are of shade part of semi-circle is 75.36 cm^2.
What is a circle?
A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.
The equation of circle in the plane is given as:
(x-h)^2 + (y-k)^2 = r^2
where (x, y) are the coordinate points
(h, k) is the coordinate of the center of a circle
and r is the radius of a circle.
and Area of circle = πr²
Now,
Area of the shaded region=area of large semicircle-2*area of small semicircles
radius for large semicircle=7cm
radius for small semicircle=3.5cm
Therefore,
Area of the shaded region=πR^2-2*πr^2
=3.14(7^2-2*3.5^2)

According to the concept of average it will take 3 days in order to get a "no homework" day.
The term called average in math is defined as the number you get when you add two or more figures together and then divide the total by the number of figures you added.
Here we know that Mrs. Bready has a large bag filled with red and green cards. She tells the class that 15% of the cards are red and 85% are green.
And here we need to determine the average number of days that it will take in order to get a "no homework" day based on these 5 trials,
Then the following calculation must be performed as,
=> 0.85 x 0.85 x 0.85 x 0.85 x 0.85 = X
=> x = 0.4437
Hence it will take 4.2 days in order to get a "no homework" day.
Here we have already know that the first trial is carried out then we have to subtract it from the total number then we get,
=> 4.2 - 1 = 3.2
When we round off the value then we get 3.

What is synthetic division?Synthetic division is a method used to perform the division operation on polynomials when the divisor is a linear factor.
When we divide a polynomial p(x) by a linear factor (x - a) (which is a polynomial of degree 1), Q(x) is the quotient polynomial and R is the remainder.
p(x)/q(x) = p(x)/(x- a) = Quotient + (Remainder/(x - a))
p(x)/(x - a) = Q(x) + (R/(x - a))
Given that, (x⁴-12x²-6)/(x+3)

What is rate of change?With the help of the tangent shown in the graph, it is estimated that the rate of change of the temperature of the cookies after 20 minutes is 0.55 °C/minute.This indicates that the temperature of the cookies is dropping at a rapid rate. After 40 minutes, the temperature has dropped from 40 °C to 30 °C, which shows a decrease of 10 °C in temperature.This rate of decrease in temperature is significant and it ensures that the cookies are cooked properly while also retaining their texture and flavor.This rapid decrease in temperature is a testament to the quality of the freshly baked cookies.This is called a rate of change. It is the rate at which the temperature of the cookies changes over time after being removed from the oven. The graph shows the temperature of the cookies over time in the form of a curve. The tangent to the curve at the point 20 minutes shows the rate of change of the temperature of the cookies.The tangent is sloping downwards, which implies that the temperature of the cookies is decreasing at a rate of 0.55°C per minute. This rate of change is referred to as the negative rate of change since it is a decrease in temperature over time.To learn more about rate of change refer to:
