This problem can be solve using the Binomial Distribution, it is a recurrence conveyance of the conceivable number of effective results in a given number of trials in each of which there is a similar likelihood of accomplishment.

Let be X: coffleton residents recognize the brand name 

n = 10 

p = 0.53

q = 0.47 

P(X = 4) = 

(10)
 
(4)*(0.53^4)*(0.47^6) = <span>0.00340</span>

b. Interpret the Rsquared value. Does the multiple regression equation help us predict the total golf score much better than we
Veseljchak [2.6K]

Answer:

Depending upon the golf score predictors we can conclude the answer from given Conditional statements

If Someone want Total golf score better then, following .condition

Yes, Because R squared is close to 1 .  ....(If Regression values are prefect to fit with model then only)

<em>(But the data is not sufficient to say 100%, it depends on score given)</em>

Step-by-step explanation:

Given :

Explanatory Question on r-squared in regression.

To Find :

Does regression equation help us to know total golf score much better.

Solution;

As  in Question there is no golf score given so we cant see "yes" or "no".

But we can be conditional here ,

1) If golf score to be accurate then , multiple regression predict points should fit the model prefect ,hence the R squared value "<em>must be close to 1</em>" .

2) If gold score is not accurate then multiple regression   suggest that model does  not explain any variables, no linear relationship.

then r squared value <em>"must not be close to 1".</em>

Depending upon the golf score predictors we can conclude the answer from given Conditional statements.

that  Yes, Because R squared is close to 1 .

The distance from the Sun to Mercury is approximately 57910000 km.
Tpy6a [65]

Mercury travels a distance of 153 461 500 kilometers on its orbit.

<h3>How much distance did Mercury travel on its orbit?</h3>

The statement indicates that Mercury has a <em>circular</em> orbit and indicates the <em>central</em> angle covered by translation. The distance traveled is found by definition of <em>circular</em> arc:

s = (2.65 rad) · (57 910 000 km)

s = 153 461 500 km

Please notice that the radius of translation is the distance from the Sun to Mercury.

Mercury travels a distance of 153 461 500 kilometers on its orbit.
