Answer:
Correlation analysis is used to quantify the degree to which two variables are related.
Step-by-step explanation:
In research, correlation analysis is a statistical approach for calculating and measuring the strength of a linear relationship between two variables. Simply defined, correlation analysis determines how much one variable changes as a result of the change in the other. A high correlation indicates a strong association between two variables, whereas a low correlation indicates a weak relationship.

T(m)= 5000+250m
how many months will it take martian to save $20,000
Answer:
60 months
Step-by-step explanation:
20 000 = 5000 + 250 m
20 000 - 5000 = 250 m
(15 000) / 250 = m = 60 months
Answer:
It would take roughly four months
Step-by-step explanation:
month one: 5,250

Points O, C, and P are collinear with O(−10, −8) and P(−2,8). Point C divides the line segment OP into the ratio 3: 5. What are the coordinates of point C?
Using proportions, it is found that the coordinates of point C are given as follows: C(-7, -2).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point C divides the line segment OP into the ratio 3:5, hence the following equation is used to relate the points:
[tex]C - O = \frac{3}{8}(P - O)[/tex]
Then, for the x-coordinate:
[tex]x + 10 = \frac{3}{8}(-2 + 10)[/tex]
x + 10 = 3
x = -7
For the y-coordinate:
[tex]y + 8 = \frac{3}{8}(8 + 8)[/tex]
y + 8 = 6
y = -2
The coordinates of point C are given as follows: C(-7, -2).

Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak. Hunger strikes and she wants to make it to Kono's for lunch; see picture. Brooke can paddle 7 mph and walk 14 mp
If she paddles along a straight line course to the shore, find an expression that computes the total time to reach lunch in terms of the location where Brooke beaches her kayak (so x = distance from A to where she lands). Be sure you remember the formula that relates Distance, Rate and Time. You're being asked for Time here
If she paddles directly to Kono's then the minimum time for the lunch will be 3.9 hours.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak.
Hunger strikes and she wants to make it to Kono's for lunch; see picture.
Brooke can paddle at 7 mph and walk at 14 mph.
Distance from Brooke to shore will be
→ √(5² + x²)
Then the time will be
[tex]t_1 = \dfrac{\sqrt{5^2 + x^2}}{2}[/tex]
Then the distance from shore to Kono's will be
→ 6 - x
Then the time will be
t₂ = (6 - x) / 4
Then the total time will be
t = t₁ + t₂
Then we have
[tex]t = \dfrac{\sqrt{5^2 +X^2}}{2} + \dfrac{6-x}{4}\\[/tex]
t = 1/4[2√(5² + x²) + 6 - x]
If she paddles directly to point A will be
t = 1/4[2√(5² + 0²) + 6 - 0]
t = 1/4 (10 + 6)
t = 16 /4
t = 4 hr
If she paddles directly to Kono's, then we have x = 6. Then the time will be
t = 1/4[2√(5² + 6²) + 6 - 6]
t = 1/4[2√61]
t = 3.9 hr

Answer:
the answer to this question is 19
Answer: m=19
Step-by-step explanation:
First you cross multiply the two fractions. So you get 9*m = 57*3.
When you put 57*3 in a calculator you get 171. So the equation is 9m=171 and then to isolate the x you divide by 9. So when you put 171/9 in a calculator you get 19. So the correct answer is C. 19.

If r=1 and 0=5pie/3, what is the approximate arc length?
Answer:
5.236 units
Step-by-step explanation:
The relation between r, θ and arc length ( l ) is,
l = rθ
l = 1 * 5π / 3
( The value of π = 3.14 approximately )
5π = 5 x 3.14 = 15.7
l = 1 * 5π / 3
= 5π / 3

Find the equation of the line that passes points
A(1,7)B(-3,-1)
Answer:
y = 2x + 5
Step-by-step explanation:
Here we have the two points as (x1=1, y1=7) and (x2 = -3, y2 = -1)
Slope of this line = (y2-y1)/(x2-x1) = (-1 -7)/(-3 - 1) = 8/4 = 2
Using slope intercept form of y = mx + c
we get y = 2 x + c
Substituing the coordinates (1,7) in this equation gives us
7 = 2.1 + c or c =5
hence y = 2x + 5
Check
if x = -3 then y = (-2)(-3) + 5 = -6 + 5 = -1 which satisfies the coordinates for the second point

Step-by-step explanation:
when x = -2:
⇒ y = 5(-2) - 1
⇒ y = -10 - 1
⇒ y = -11
when x = 0:
⇒ y = 5(0) - 1
⇒ y = 0 - 1
⇒ y = -1
when x = 2:
⇒ y = 5(2) - 1
⇒ y = 10 - 1
⇒ y = 9
when x = 4:
⇒ y = 5(4) - 1
⇒ y = 20 - 1
⇒ y = 19
A furniture shop produces two types of custom made chairs. If the price of one type of chair is three times the price of the other, and the total price for both is $15365, what is the price of other chair?
Answer:
The price of other chair is $3841.25
Step-by-step explanation:
Step 1: Write equations.
First equation: The price of one type of chair is three times the price of the other.
Let x be the price of one type of chair and y the price of the other type of chair.
[tex]x = 3y[/tex]
Second equation: The total price for both is $15365
[tex]x + y = 15365[/tex]
Step 2: Solve the system of equations.
1) [tex]x = 3y[/tex]
2) [tex]x + y = 15365[/tex]
Substitute x in the second equation with x from first.
[tex]x + y = 15365\\(3y) + y = 15365[/tex]
Now solve for y (y is the price of the other chair).
[tex]4y = 15365\\y = \frac{15365}{4}\\y = \$3841.25[/tex]
