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:
h=V πr2
Step-by-step explanation:
1: Find the volume of the cylinder. Volume: 120 = h=V πr2
2: Since there is no radius the answer will be that and we also finding the for the cone.
3: Volume of the cone will be h=V πr2 since we finding for the volume for both.
Hope this helps.
Answer:
B.
Step-by-step explanation:
5x + y = 3
10x + 2y = - 3
y = - 5x + 3
2y = - 10x - 3
y = - 5x + 3
y = - 5x - 3/2
These lines have the same slope, but different y-intercept, so they are parallel.
