A line has a slope angle of 63.5° and passes through the point (2, 3). What is the..
a) approximate slope of the line
b) equation of the line
a) The approximate slope of the line is; 2
b) The equation of the line is; y = 2x - 1
What is the equation of the line?The tangent of the angle formed by a straight line will give us the slope of the line.
a) Now, we are told that the slope angle is 63.5°. Thus;
Slope of given line = tan 63.5°
Slope = 2
b) The formula for equation of a line in point slope form is;
y - y₁ = m(x - x₁)
where m is slope
The line passes through the point (2, 3). Thus;
Equation of line is;
y - 3 = 2(x - 2)
y - 3 = 2x - 4
y = 2x - 1

Therefore , the solution of the given problem of relative frequency comes out to be 20% of student population is between the ages of 35 and 38.
Where can I find the relative frequency?To find it, multiply the ratio of the total number of pupils (2 + 2 + 8 + 2 + 10 + (6 = 30) by 100%, which equals the number of individuals with a lower limit of 35 (of whom there are 6).
Here,
Simply put, the relative frequency in this case is
20%: RF = (6/30)*100%
Consequently, 20% of student population is between the ages of 35 and 38.

After a 5% tax,a DVD costs $21.How much did it cost before the 5% tax was added?
Answer:
$20
Step-by-step explanation:
You want to know the pre-tax price if the price with 5% tax added is $21.
TaxThe added tax is 5% of the original amount (x), so the amount with tax added is ...
$21 = x + 0.05x = 1.05x
$21/1.05 = x = $20 . . . . . divide by the coefficient of x
The cost before tax was added was $20.
Step-by-step explanation:
Percentage left after the tax percentage is
100%-5%=95%
95% is equal to 95/100 = 0.95
therefore, the cost after tax divided by the percentage that is left after the tax percentage
costs after tax is 21 dollars which is
21/0.95 = 22.1dollars

the scatter plot shows the number of hours Nisha works an d the numbers of pairs of ghungaroos she makes the equation y= 4.75x - 2.5 is a good line fit for the data. using the equation of the line how many hours will it take Nisha to make 64 pairs of ghungaroos
The hours that it would take Nisha to make the gungharoos is 301.5 hours
How to solve for the hoursThe equation of the line in the scatter plot is given as
y= 4.75x - 2.5
Where x is the number of ghungaroos that Nisha would make
We have to put in the value of x as 64 because the question tells us that She made a total of 64 gungharoos
Hence we would have:
y = 4.75 * 64 - 2.5
y = 304 - 2.5
y =301.5
The hours that it would take Nisha to make the gungharoos is 301.5 hours

"Choice D" The dot plot with the outlier at 4 feet and data points condensed on the right from 5.5-7 feet is the correct dot plot.
Step-by-step explanation:
ExplanationA dot plot is a statistical chart consisting of data points plotted on a simple scale, typically using filled-in circles.
A skew represents the direction in which the data points follow.
A negative skew indicates that the majority of the data points fall on the left side of the scale. Ex: "The height of the sunflowers in feet decreases when less sunlight is given."A positive skew indicates that the majority of the data points fall on the right side of the scale. Ex: "The height of the sunflowers in feet increases when more sunlight is given."An outlier is a data point that "stands out" from other data points.
Answer BreakdownChoices A and B are skewed left because their data points lie on the left side of the number line. These data points display a decrease in the sunflowers' height. So they are automatically eliminated. Choice C is skewed right, however, it contains no outliers. All the data points are condensed evenly to one side. This answer is incorrect. Choice D is the correct answer. The data points lie on the right side of the scale. There is also one outlier present at 4 feet, separating it from the rest of the data points.Please let me know if this helped!!!

What is a function?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).
There are several types of functions in math. Some important types are:
Injective function or One to one function: When there is mapping for a range for each domain between two sets.
Surjective functions or Onto function: When there is more than one element mapped from domain to range.
Polynomial function: The function which consists of polynomials.
Inverse Functions: The function which can invert another function.

The number of days took to get the video of Felipe 1024 views is 4.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
The relationship between the elapsed time in days, d, since the video was uploaded and the total number of views, v, that the video received is modeled by the equation,
v = 4^(1.25d)
We have to find d when v = 1024
1024 = 4^(1.25d)
We have the rule for exponents aᵇⁿ = (aᵇ)ⁿ
1024 = [tex](4^{1.25} )^d[/tex]
1024 = (5.6569)^d
Taking logarithms on both sides,
㏒ (1024) = ㏒ [(5.6569)^d]
We have the exponent rule for logarithm, ㏒ (aᵇ) = b ㏒ (a)
㏒ (1024) = d ㏒ (5.6569)
d = ㏒ (1024) / ㏒ (5.6569)

How to calculate the word problem?A word problem in mathematics simply refers to a question that is written as a sentence or in some cases more than one sentence which requires an individual to use his or her mathematics knowledge to solve the real.life scenario given.
In this case, Jennifer has 256 beads stella has 3 times more beads tiah had 104 beads.
The total number of beads will be:
= 256 + (256 × 3) + 104
= 256 + 768 + 104
= 1128

Complete question
Jennifer has 256 beads stella has 3 times more beads tiah had 104 beads. What is the total number of beads?
Suppose that a is inversely proportional to b. Let a1,a2 be two nonzero values of a such that {a1}/{a2}={2}/{3}. Let the corresponding b values be b1,b2. If b1,b2 are nonzero, find the value of {b1}/{b2}
If b1,b2 are nonzero, the value of {b1}/{b2} will be 3/2.
If a is inversely proportional to b. Let a1,a2 be two nonzero values of a such that {a1}/{a2}={2}/{3}. Let the corresponding b values be b1,b2. If b1,b2 are nonzero
a = k *1/b
2/3 =k * 1/b1 /k * 1/b2 [k = constant cancels out]
2/3 =1/b1 * b2
2/3 = b2/b1
b1 =3 and
b2 =2. Therefore:
b1/b2 =3/2.
Another way of looking at it, is this:
When a1 =2, b1=1/2
When a2 =3, b2=1/3
So, when a1/a2 = 2/3, then:
b1/b2 =(1/2) / (1/3) =(1/2) x (3/1)
=3/2
