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:
Step-by-step explanation:
Janet uses less than 4 cups of flour because 3/8 is less than one.
I believe the correct answer to your question would be choice B. The trail is no more than 6 miles long.
A. time and distance
1.distance depends on time
2. independent. time
dependent. distance
b. y=50x
input number put in for x
output the y value after its solved.
2a. y=50(6)
y=300
2b. no it will travel 25 miles less because if you plug 4 in for x it equals 200
hope this helps
