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

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

If the town will permit a parking lot at angle J if the measure of angle Ji is greater than 38°, then yes, a parking lot can be erected at angle K.
what is angle ?In Euclidean geometry, an angle is a shape that is made up of two rays, known as the hood's sides, that meeting at a middle point known as the wall's apex. Two rays may combine to form an angle in the planes where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two photons or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, sometimes known as two sides of the angle, converge.

Write an equation of the line that passes through (1,2) and is perpendicular to the line y=1/3x+4
The line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).
What is the equation of the line?A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.
On the y-axis, this value c is referred to as the intercept.
Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
y = 1/3x + 4 is the line that crosses (1,2) and is perpendicular to it.
To ascertain the equation of the line, utilize the procedures below:
Step 1: Two lines that are perpendicular to one another have the following slopes:
mm' = 1
Where the slopes of the lines are m and m'.
Step 2 - The line that is perpendicular to the line (y = 1/3x + 4) has the following slope:
1/3 * m' = -1
m' = -3
Step 3: The equation for a line passing through the points (1, 2) and having a slope of -3 is as follows:
(y - 2) = -(x - 1)
Implicate the equation above:
y = -3x + 5

Answer:
See attached photo.
"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!!!

c. Find an equation for the sequence
Answer:
a) See below.
b) Arithmetic sequence
[tex]\textsf{c)} \quad a_n=10n-7[/tex]
Step-by-step explanation:
Part (a)From inspection of the given table, t(n) increases by 10 each time n increases by 1.
Therefore:
[tex]\implies a_7=53+10=63[/tex]
[tex]\implies a_8=63+10=73[/tex]

Part (b)As the given sequence has a constant difference of 10, it is an arithmetic sequence.
Part (c)[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]
The common difference is 10. Therefore:
d = 10To find the first term, a, substitute the value of d and one of the terms into the formula:
[tex]\begin{aligned}\implies a_4=a+(4-1)(10)&=33\\a+3(10)&=33\\a+30&=33\\&a=3\end{aligned}[/tex]
Therefore, to write an equation for the given arithmetic sequence, substitute the found values of a and d into the formula:
[tex]\implies a_n=3+(n-1)(10)[/tex]
[tex]\implies a_n=3+10n-10[/tex]

What do you add to 5 5/8 to make 7 as an improper fraction?
Answer: We need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅
PLEASEEEE GIVE BRANLIEST
Step-by-step explanation: To add 5 5/8 to a number to make 7 as an improper fraction, we need to convert 5 5/8 to an improper fraction.
To convert a mixed number to an improper fraction, we take the whole number, multiply it by the denominator of the fraction, and add the numerator. So, 5 5/8 becomes (5 x 8) + 5 / 8 = 40 + 5 / 8 = 45/8.
Now, we can add 45/8 and the number that we need to add to make 7 as an improper fraction.
45/8 + x = 7
To find x, we can subtract 45/8 from both sides of the equation:
x = 7 - 45/8
x = 1 7/8
So, we need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅
Consider functions f and g. f ( x ) = 1 − x 2 g ( x ) = 11 − 4 x Evaluate each combined function, and match it to the corresponding value.
The value of the combined function f(g(x)) will be -16x^2+88x-120.
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.
Now,
Given functions are f(x)=1-x^2 and
g(x)=11-4x
Therefore,
the combined function will be f(g(x))=1-(11-4x)^2
