Answer: c. 10
Step-by-step explanation:
Given : An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment.
For this study, the three sample means are, M1 = 1, M2 = 2, and M3 = 3.
Grand mean =
[All sample have equal elements]

For ANOVA,
, where i= 1, 2 , 3


Hence,the value would be obtained for
.
hence, the correct answer = c. 10
Answer: 16.13
Step-by-step explanation: 40 divided by $2.48
What are the angles?
if all of them are below 90 degrees, it is acute.
if one angle is 90 degress, it is right
if one angle is more than 90 degrees, it is obtuse
Answer:
angle A=54 degree
angle B =36 degree
Step-by-step explanation:
let angle B be x
angle A=x+18
since they are complementary angles sum of these two angles will be 90 degree
x+x+18=90
2x=90-18
2x=72
x=72/2
x=36 degree
substitute the value of x to find angle A and angle B
for angle A
x+18
36+18
54 degree
for angle B
angle B =x
=36 degree
Answer:

Step-by-step explanation:
The formula of a surface area of a cylinder:

r - radius
H - height
We have r = 40mm and H = 50mm. Substitute:
