um where’s the question?
Which among the following statements regarding correlation coefficient is/are correct? Group of answer choices Its absolute value cannot exceed 1. It only takes non-negative values. A positive value indicates a strong correlation between the two variables; a negative value indicates a week correlation between the two variables. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find b positive. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find a positive.
Answer:
The correct statements regarding correlation coefficient are:
1. Its absolute value cannot exceed 1.
2. A positive value indicates a strong correlation between the two variables; a negative value indicates a weak correlation between the two variables.
3. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find b positive.
4. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find a positive.
Step-by-step explanation:
Correlation measures the strength of the relationship which exists between X and Y variables. Regression, on the other hand, helps to establish a cause and effect between a dependent variable and an independent variable.

A Playstation 5 gaming console is initially priced at $500 and the prices rises such that the new price is $550. What is the percent increase of the Playstation 5? Show all work, write answer using proper units.
Answer:
10%
Step-by-step explanation:
Percentage increases is given by the formula:
[tex]percentage \: increases = \frac{increases}{original \: value} [/tex]
Increases = $550 - $500 = $50
Original Value: $500
substitute the values into the formula
[tex]percentage \: increases = \frac{50}{500} \times 100[/tex]
= 10%
Find the zeros from the factored form Quadratic Equation y=-x(x-3) ( ,0) & ( ,0)
Answer:
(0, 0) and (3, 0)
Step-by-step explanation:
Zeros of any equation means, value of variable x at y = 0.
Given quadratic equation is,
y = -x(x - 3)
For y = 0,
-x(x - 3) = 0
x = 0
And (x - 3) = 0
x = 3
Therefore, x-intercepts of the given quadratic equation will be,
x = 0, 3
Points showing the x-intercepts will be,
(0, 0) and (3, 0)
The variables x and y are related proportionally. When x = 8 and y = 20. Find y when x = 68.
Answer:
y = 170
Step-by-step explanation:
68/8 = 8.5
8.5*20 = 170
Answer:
170Steps:
given: when x = 8 , y = 20
if x = 68
then y = (68 × 20)/8 = 1360/8 = 170

Find the slope of the line passing through the points (-6-9) and (9,-9)
Find the slope of the line passing through the points (4,1) and (4,-5).
9514 1404 393
Answer:
zeroundefinedStep-by-step explanation:
The slope formula is useful for this.
m = (y2 -y1)/(x2 -x1)
__
First line:
m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0
The slope of the first line is zero.
__
Second line:
m = (-5-1)/(4 -4) = -6/0 = undefined
The slope of the second line is undefined.

It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.
Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.
Hello there! We're provided with two problems in one, but we can solve each of them by using the slope formula, which is this:
[tex]\stackrel\diamond{\boxed{\boxed{\bold{\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]
In this formula,
[tex]\sf{y_2=-9}[/tex][tex]\sf{y_1=-9}[/tex][tex]\sf{x_2=9}[/tex][tex]\sf{x-1=-6}[/tex]Plug in the values:
[tex]\sf{\dfrac{-9-(-9)}{9-(-6)} =\dfrac{-9+9}{9+6} =\dfrac{0}{15} =\boxed{0}}[/tex]So the slope is 0.
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
The second problem can be solved the same way!
Once again, we'll use the formula
[tex]\stackrel\diamond{\boxed{\boxed{\bold{\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]
only this time, the values are different:
[tex]\sf{y_2=-5}[/tex][tex]\sf{y_1=1}[/tex][tex]\sf{x_2=4}[/tex][tex]\sf{x_1=4}[/tex]Plug in the values:
[tex]\sf{\dfrac{-5-1}{4-4} =\dfrac{-6}{0} =\boxed{unde fined}[/tex]So the slope's undefined. I hope this helps, feel free to comment if you have any queries regarding the slope formula! ^^

Find the value of x in the triangle shown below 6 2
Answer:
x = 2√10 = 6.325
Step-by-step explanation:
a² +b² = c² a = 6 b = 2 c = x
c = √(a² +b²)
c = √(6² +2²)
c = √(36 +4)
c = √(40)
c = 2√10

The giant outlier is Palm Beach county. We can see that it lies well beyond the range of votes this regression model would predict for Buchanan, based on the observed linear trend between total votes and votes for Buchanan across all the other counties. Calculate the residual for Palm Beach county to determine just how much larger Buchanan's vote total was compared to what we'd predict based on the election results from the other counties.
Answer:
Hello your has some missing information attached below is the missing information
answer : 2355.62
Step-by-step explanation:
Calculating the residual for Palm Beach county
Given that total votes = 430772
and The regression equation = 56.115131 + 0.0023197 * Total Votes
The predicted Buchanan = 56.115131 + 0.0023197 * 430772 = 1055.377
while the Actual Votes Buchannan = 3411
Residual for Palm Beach county = Actual votes Buchannan - Predicted
= 3411 - 1055.377 = 2355.62

a certain vehicle can drive 300miles on a tank of 20 gallons. how far can it drive on 30 gallons?
what’s the answer in miles?
PLEASE HELP ME OMG!!!
Answer:
The vehicle can drive 450 miles.
Step-by-step explanation:
You must find how many miles the car goes on one gallon, so since 300÷20= 15, you then know that the car can travel 15 miles per gallon. Therefore, you must do 15 x 30 to get 450 miles.
Answer:
450 miles
Step-by-step explanation:
By 20 gallons,the car travels 300 miles
by 1 gallon, car travels 300÷ 20 miles
By 30 Gallons, car travels: (300÷20 )×30
450miles

The distance that an object falls when it is dropped is directly proportional to the
square of the amount of time since it was dropped. An object falls 288 feet in 3
seconds. Find the distance the object falls in 4 seconds,
Answer:
The object falls 384 feet in 4 seconds.
Step-by-step explanation:
This question can be solved by proportions, as the measures are directly proportional, using a rule of three.
An object falls 288 feet in 3 seconds. Find the distance the object falls in 4 seconds.
288 feet - 3 seconds
x feet - 4 seconds
Applying cross multiplication
[tex]3x = 288*4[/tex]
[tex]x = \frac{288*4}{3}[/tex]
[tex]x = 384[/tex]
The object falls 384 feet in 4 seconds.
Find the lateral area of this cone.
Leave your answer in terms of pi
15cm
8cm
Answer:
lateral surface area of cone =
[tex]\pi rl[/tex]
where, l = slant height, and r = radius
then
[tex]l.a = \pi \times 8 \times 17[/tex]
[tex]l.a = 136\pi[/tex]
The lateral area of this cone will be 136 π. Lateral area is found as the product of pi ,radius and slant height.
What is a cone?It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
lateral area of this cone is found as;
L=πrl
L=π×8×17
L=136π
Hence,the lateral area of this cone will be 136 π.
