Answer:
Step-by-step explanation:
Hello!
A regression model was estimated in order to test if the number of units of a restaurant chain affecta the sales of said restaurant chains.
The estimated model is:
Y= a + bX
Where
Y: is the sales of a restaurant chain
X: number of units of a restaurant chain
Looking at the computed data, the estimated coefficients are:
a= 4.633131413
b= 0.439724072
The correct regression equation to predict Sales based on Units, according to this analysis, is..
Y= 4.63 + 0.44X
I hope it helps!
Well for this you can use simple multiplication or you can do a table like this
38.99. keep in mind to go through the
× 82. 2 first before going to 8
______
7798 make sure to add a zero for
+311920 each time you go down
_______
319718.
so you have you're answer but you have to make sure you put your decimal back so since it was in two places move the decimal to the left 2 times then you have your answer
answer- $3,197.18
4,300 would be the nearest 100's
So Wilson has 60 chocolates and we know 50% of 60= 30
So 30 - 20%= 18
18 is your answer
