Answer:
Your correct answer is 4.73x^10000100
Answer: x= -(1/2)
Step-by-step explanation:
(x+5 +3) / x+3 = 3
Multiply both sides by (x+3)
(x+8)= 3(x+3)
x+8 = 3x+9
-2x = 1
x= -1/2
CHECK:
-1/2 +8 = 15/2 -1/2+3 =5/2
15/2 : 5/2 = 15/2*(2/5) = 30/10 = 3
Subtract 9 from both sides of the '=' sign
9 - 9 + b = -8 -9
b = -17 That's the answer.
Answer:
d. 0.0948 ± 4.032(0.0279)
Step-by-step explanation:
A 99% confidence interval for the coefficient of promotional expenditures is, First, compute the t critical value then find confidence interval.
The t critical value for the 99% confidence interval is,
The sample size is small and two-tailed test. Look in the column headed es = 0.01 and the row headed in the t distribution table by using degree of freedom is here
for (n-2=5) degree of freedom and 99% confidence ; critical t =4.032
therefore 99% confidence interval for the slope =estimated slope -/+ t*Std error
= 0.094781123 -/+ 4.032* 0.027926367 = -0.017822 to 0.207384
