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
Answer:
1:3
Step-by-step explanation:
Both numbers are divisible by 25:
∴ The simplified ratio is 1:3
Hope this helps!
14+x=22
I think this will be the answer because it shows how many he already had and it is solvable.
Subtract 14 from both sides and you get eight.
X=8
Answer:
(1/2)(x³ - 3)
Step-by-step explanation:
That would be (1/2)(x³ - 3).
(f+g)(x)=6x-4
(f-g)(x)=-2x+6
(f*g)(x)=6x^2-6x-5
