Answer:
Step-by-step explanation:
Given that in a study of a weight loss program, 4 subjects lost an average of 48 lbs.
It is found that there is about a 32% chance of getting such results with a diet that has no effect.
The results do not appear to have statistical significance. The reasons are
1) Sample size of 4 is very small not even meeting the bare minimum
2) Sample of 4 cannot be taken to represent the population
3) Whether bias was there in the selection of sample is not known.
4) Std deviation is not considered which is very important while concluding results.
Answer:
The volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume.
Step-by-step explanation:
The volume of a cylinder having base area 'A' and height 'H' is given by V = AH, and the volume of a cone having the same base area as the cylinder i.e. A and height 3 times the height of the cylinder i.e. 3H is given by 
.
So, V = V'
Hence, the volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume. (Answer)
Answer:
admission price of each parent = $7.5
admission price of each child = $15
Step-by-step explanation:
x = admission price of each parent
y = admission price of each child
Robinson family:
2x + 4y = 75
Moore family:
2x + 3y = 60
2x + 4y = 75 (1)
2x + 3y = 60 (2)
Subtract (2) from (1)
4y - 3y = 75 - 60
y = 15
Substitute y = 15 into (1)
2x + 4y = 75
2x + 4(15) = 75
2x + 60 = 75
2x = 75 - 60
2x = 15
x = 15/2
x = 7.5
Answer:
850 but im not sure lol
Step-by-step explanation:
645 + 225 = 870
1,320 - 870 = 450
450 + 350 = 800
800 + 50 = 850
