Answer:
(A) For each additional hundred dollars spent on advertising, sales are predicted to increase by $2,380.
Step-by-step explanation:
Regression isa statistical equation, denoting relationship between independent (causal) variable(s) & dependent (effected) variable.
y = a <u>+</u> bx
where y = dependent variable, x = dependent variable, a (intercept) = autonomous value of y, b (slope) = change in y due to change in x
Regression equation of independent variable (x) as advertising expenditure & dependent variable (y) sales : y = 24.45 + 2.38x
Sales are in thousands of dollars, advertising expenditure is in hundreds of dollars. So, the interpretations are :
- Intercept interpretation : When there is zero advertising expenditure, sales are 24.45 thousands i.e $24450
- Slope Interpretation :<u> When advertisement expenditure change (rise) by 1 hundred, sales change (rise) by 2.38 thousand i.e</u><u> </u><u>$2380</u>
Subtract the two numbers to find the measurement of the leftover piece
5.6 - 1.71 = 3.89 feet
Answer:
(2 + 5) / (9 - 4)
Step-by-step explanation:
"sum of 2 and 5" = (2 + 5)
"difference of 9 and 4" = (9 - 4)
"sum of 2 and 5 is divided by the difference of 9 and 4"
= (2 + 5) / (9 - 4)
