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.

Answers

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.

Step-by-step explanation:

An angle that is vertical to <UXR is an angle that is directly opposite to <UXR, which share the same vertex, X, as <UXR.

From the diagram given, the angle number that shares the same vertex as <UXR and is directly opposite to <UXR is angle number 1 (<SXT).

Step-by-step explanation:

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!!!

Answers

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

For which product or quotient is this expression the simplest form? (image attached)! please help :((

Answers

Answer:

D

Step-by-step explanation:

For simplify the work we can start to factorise all the possibles expressions:

2x + 8.

8 is multiple of 2, so it can became

2(x+4)

x^2 - 16 this is a difference of two squares, so it can be rewritten as:

(x+4)(x-4)

x^2 + 8x + 16

we have to find two numbers whose sum is 8 and whose product is 16

the two number are 4 and 4

it becames:

(x+4)(x+4)

x+ 4 can‘t be simplified

if we look at the expression, we can find that x-4 appears at the numerator so

x^2 - 16 must be at numerator

but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option

in fact

(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)

it became

(x+4)(x-4)/2 * 1/(x+4)(x+4)

(x-4)/2(x+4)

Find the lateral area of this cone.
Leave your answer in terms of pi
15cm
8cm

Answers

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.

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.

Answers

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
