<span>Find the ratio of the number of cans in a store:
=> Shop smart = 24 packs (2 for $9)
=> super saver = 12 packs (4 for $10)
=> Price Buster = 12 packs (3 for $ 9)
Let’s start with the first, the shop smart
=> 2/24 = 9/x
=> 4.5 x 2 = 9, thus 4.5 x 24
= 108
=> 2:24 = 9/108
Second, Super Saver
=> 4/12 = 10/x
=> 4 x 2.5 = 10, thus 2.5 x 12
=> 30
=> 4:12 = 10:30
Third, Price Buster
=> 3/12 = 9/x
=> 3 x 3 = 9, thus 3 x 12
=> 36
=> 3:12 = 9:36

Answer:
x = 
Step-by-step explanation:
We have the equation: 3 + 
= 
Move the constant (in this case the constant is 3) to the right side of the equation, changing its sign
= - 3
Calculate the difference.
= 
Divide.
(when dividing two fractions, you can change it to a multiplication problem by switching the numerator and denominator of the divisor.)
So, we get the equation x 
which is .
I hope this helps!
Answer:
d) Squared differences between actual and predicted Y values.
Step-by-step explanation:
Regression is called "least squares" regression line. The line takes the form = a + b*X where a and b are both constants. Value of Y and X is specific value of independent variable.Such formula could be used to generate values of given value X.
For example,
suppose a = 10 and b = 7. If X is 10, then predicted value for Y of 45 (from 10 + 5*7). It turns out that with any two variables X and Y. In other words, there exists one formula that will produce the best, or most accurate predictions for Y given X. Any other equation would not fit as well and would predict Y with more error. That equation is called the least squares regression equation.
It minimize the squared difference between actual and predicted value.
