1/7 and 3/14......common denominator is 14
2/14 = 3/14
cross multiply
(14)(3) = (14)(2)
42 = 28...not correct...no, this does not form a proportion
little tip ** proportions are nothing but equivalent fractions and 1/7 does not equal 3/14...now if it would have been 1/7 and 2/14...then it would have been a proportion

Step-by-step explanation:
Hello!
A linear regression for the price of renting a room in a hotel and the rating said hotel received was calculated from a sample of n= 25 hotels.
The theoretical regression model is E(Y)= α + βXi
And the estimated regression equation is: ^Y= a + bXi
Where:
The estimator for the slope is b= 125
And the estimator of the Y-intercept is a= -400
So for this example the estimated regression line for the price of the hotel rooms given the ratings of the hotel is:
^Y= -400 + 125 Xi
^Y= represents the estimated average price of a hotel room
a= -400 is the estimated average price of a hotel room when the rating of the hotel is zero.
b= 125 is the modification of the estimated average price of a hotel room when the rating of the hotel increases one unit.
I hope this helps!
it's 8,
let the no. of tired students be x
add all the numbers of the happy, hungry and in between students and then subtract from the total of the student
which has to look smth like this
happy = 10
so we fill all the numbers in between then we add them and see what's missing
1+3+2 = 6
10-6 = 4
4 students are happy
hungry = 7
1+1+3 = 5
7-5 = 2
2 students are hungry
and lastly for tired, they didn't mention the total so we add all the numbers we got and subtract them by the total of students (just like mentioned above)
2+1+1+3+4+2 = 13
21-13 = 8
8 students were tired
x = 8
