When analyzing two quantitative variables, what is the first thing that should be done?.
When analyzing two quantitative variables the first thing that should be done make a scatterplot.
When comparing two quantitative variables, a scatterplot is the most useful display technique. We plot the variable we consider the response variable on the y-axis and the explanatory or predictor variable on the x-axis.
How do we know which variable is which? The explanatory variable, in general, attempts to explain or predict the observed outcome. A study's outcome is measured by the response variable. One may even consider investigating whether one variable causes variation in another variable; for example, a popular research study found that taller people are more likely to earn higher wages. In this case, the explanatory variable Height would be used to explain the variation in the response variable Salaries.
When summarizing the relationship between two quantitative variables, we must consider the following:
1.Association/Direction (i.e. positive or negative)
2.Form (i.e. linear or non-linear)
3.Strength (weak, moderate, strong)

According to the Pythagoras theorem, the value of x is 13.8
Pythagoras theorem:
Pythagoras theorem describes that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
Given,
Here we have the two right angled triangles with the side values.
Here we have to find the value of x.
In order to find the value of x, we have to find the value of the bisector KM,
So, for that we have to use the concept of Pythagoras theorem,
We can written this one the following type of equation,
=> (12.3)² = (5.4)² + KM²
=> 151.29 = 29.16 + KM²
=> KM² = 122.13
=> KM = 11.05
Therefore, the value of x is calculated in the same manner,
=> x² = (8.2)² + (11.05)²
=> x² = 67.24 + 122.10
=> x² = 189.34
=> x = √189.34
=> x = 13.76
When we round off this into the nearest tenth the we get the value of x as 13.8.

Step-by-step explanation:
Given equation:
[tex]9^{\log_3 (\log x)}= \log x-2\log^2x+4[/tex]
Rewrite 9 as 3²:
[tex]\implies (3^2)^{\log_3 (\log x)}= \log x-2\log^2x+4[/tex]
[tex]\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:[/tex]
[tex]\implies 3^{2\log_3 (\log x)}= \log x-2\log^2x+4[/tex]
[tex]\textsf{Apply the log power law}: \quad \log_ax^n=n\log_ax[/tex]
[tex]\implies 3^{\log_3 (\log x)^2}= \log x-2\log^2x+4[/tex]
[tex]\textsf{Apply log law}: \quad a^{\log_ab}=b[/tex]
[tex]\implies (\log x)^2= \log x-2\log^2x+4[/tex]
Simplify:
[tex]\implies\log ^2 x= \log x-2\log^2x+4[/tex]
[tex]\implies 3\log ^2 x- \log x-4=0[/tex]
Let log(x) = u:
[tex]\implies 3u^2-u-4=0[/tex]
Factor:
[tex]\implies 3u^2+3u-4u-4=0[/tex]
[tex]\implies 3u(u+1)-4(u+1)=0[/tex]
[tex]\implies (3u-4)(u+1)=0[/tex]
Apply the zero-product property:
[tex]\implies 3u-4=0 \implies u=\dfrac{4}{3}[/tex]
[tex]\implies u+1=0 \implies u=-1[/tex]
Substitute u=log(x) back in:
[tex]\implies \log x = -1[/tex]
[tex]\implies \log x= \dfrac{4}{3}[/tex]
On the left side of the original equation, we have log₃ (log x).
As logs of negative numbers cannot be taken, log(x)=-1 is not a valid solution since this would give log₃(-1) which is undefined.
Therefore, the only valid solution is:
[tex]\implies \log x= \dfrac{4}{3}[/tex]
[tex]\implies x=10^{\frac{4}{3}}[/tex]
[tex]\implies x=\left(10^4\right)^{\frac{1}{3}}[/tex]
[tex]\implies x=10000^{\frac{1}{3}}[/tex]
[tex]\implies x=\sqrt[3]{10000}[/tex]
Note: If a log has no base, assume that the base is 10.

The length of the side x on the right triangle is 41.06
What is a right triangle?A right triangle is a triangle that has one interior angle of 90°
The parameters in the right triangle are;
Acute angle = 47°
Leg length of side adjacent to 47° = 28
Length of the hypotenuse = x
From trigonometric ratios, we have;
[tex]cos(\theta) =\mathbf{ \dfrac{Length \, of \, adjacent \, side}{Length \, of \, Hypotenuse}}[/tex]
The cosine of the 47° angle is therefore;
[tex]cos(47^{\circ}) = \dfrac{28}{x}[/tex]

Answer:
5.5%
Step-by-step explanation:
You want the interest rate that can be compounded continuously to give $1490 from an investment of $650 after 15 years.
ValueThe formula for account value with continuously compounded interest is ...
A = Pe^(rt) . . . . P=principal, r=interest rate, t=years
Interest rateSolving for r, we find ...
ln(A/P)/t = r
ln(1490/650)/15 = 0.0553...

In the expansion (2+3x)^n .the coefficient of x^3 and x^4 are in the ratio if 8:15 find n
In the binomial expansion of (2 + 3x)ⁿ, the value of n = 22/5
What is binomial expansion?Binomial expansion is the expansion of the binomial (a + b)ⁿ = ∑ⁿCₓaˣbⁿ⁻ˣ where ⁿCₓaˣbⁿ⁻ˣ is the general term and x = 0 to n
How to find the ratio of the coefficients of x³ and x⁴ in the expansion of (2 + 3x)ⁿ?Since we require the expansion of (2 + 3x)ⁿ, comparing it with the binomial expansion equation above (a + b)ⁿ.
So, a = 2 and b = 3x
So, the binomial expansion is (2 + 3x)ⁿ = ∑ⁿCₓ2ˣ(3x)ⁿ⁻ˣ
= ∑ⁿCₓ2ˣ(3ⁿ⁻ˣ)xⁿ⁻ˣ
So, the general term of (2 + 3x)ⁿ = ∑ⁿCₓ2ˣ(3ⁿ⁻ˣ)xⁿ⁻ˣ and the coefficient term is ⁿCₓ2ˣ(3ⁿ⁻ˣ)
Now since coefficient of x³ and x⁴ are in the ratio if 8:15. Then
For the x³ term, xⁿ⁻ˣ = x³
⇒ n - x = 3
⇒ x =n - 3
So, substituting this into the coefficient term, we have
ⁿCₓ2ˣ(3ⁿ⁻ˣ) = ⁿCₙ₋₃2ⁿ⁻ˣ(3³) =
Also, for the x⁴ term, xⁿ⁻ˣ = x³
⇒ n - x = 4
⇒ x =n - 4
So, substituting this into the coefficient term, we have
ⁿCₓ2ˣ(3ⁿ⁻ˣ) = ⁿCₙ₋₄2ⁿ⁻ˣ(3⁴)
Now since coefficient of x³ and x⁴ are in the ratio if 8:15, we have that
ⁿCₙ₋₃2ⁿ⁻ˣ(3³)/ⁿCₙ₋₄2ⁿ⁻ˣ(3⁴) = 8/15
ⁿCₙ₋₃/(ⁿCₙ₋₄ × 3)= 8/15
ⁿCₙ₋₃/ⁿCₙ₋₄= 8/15 × 3
ⁿCₙ₋₃/ⁿCₙ₋₄= 8/5
n!/(n - 3)![n - (n - 3)]! ÷ n!/(n - 4)![n - (n - 4)]! = 8/5
n!/(n - 3)![n - n + 3)]! ÷ n!/(n - 4)![n - n + 4)]! = 8/5
n!/(n - 3)!3! ÷ n!/(n - 4)!4! = 8/5
n!/3!(n - 3)! ÷ n!/4!(n - 4)(n - 3)! = 8/5
n!/3!(n - 3)! × 4!(n - 4)(n - 3)!/n! = 8/5
4!/3! × (n - 4) = 8/5
4 × 3!/3! × (n - 4) = 8/5
4(n - 4) = 8/5
Dividing through by 4, we have
(n - 4) = 8/(5 × 4)
(n - 4) = 2/5
Cross-multiplying, we have
5(n - 4) = 2
Expanding the brackets, we have
5n - 20 = 2
5n = 20 + 2
5n = 22
n = 22/5

Calculate Average Speed
A train leaves London at 11:30 and arrives in Brighton at 12:30.
The distance between the two stations is 80 km.
Find the average speed in km/h.
Answer:
The average speed is 80km/h.
Step-by-step explanation:
In order to calculate the average speed you have to divide the total distance by the total elapsed time:
Let t represent time (in hours)
t=12:30-11:30=1
Let D represent distance (in kilometers)
D=80
Therefore, since t=/=0:
D/t=80/1=80km/h
And there you have it! Your answer is 80 km per hour.

Which three inequalities can model this situation? Select all the correct answers. x(15 + 400) > 520 520 < 400 + 15x 15x > 120 15x + 520 > 400 520 < 15x + 400x 15x + 400 > 520
According to the given expression, the inequality that can model the given situation can be stated as 520 < 400 + 15x.
Since Dan wants to know how many hours he needs to spend walking dogs, let us assume this to be x:
15x + 400
Dan wants to know how many hours he needs to spend walking dogs to earn more than $520 in a week. So the above expression is greater than 520:
15x + 400 > 520
When400 is subtracted from 520, the result is true:
15x > 120
Thus, the first inequality expression can be rearranged as:
