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>
Answer:
The number is 10/3
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Three times a number increased by ten is equal to twenty
(3n) + 10 = 20
<u>Step 2: Subtract 10 from both sides</u>
3n + 10 - 10 = 20 - 10
3n = 10
<u>Step 3: Divide both sides by 3</u>
3n / 3 = 10 / 3
n = 10/3
Answer: The number is 10/3
