Answer:
d. I and III only
Step-by-step explanation:
I. The seeds should be randomly assigned to a treatment.
III. The number of successful seeds and unsuccessful seeds in each group should be at least 10.
The distribution of difference between two sample proportions :
Given :
Proportion 1 = P1 ;
Proportion 2 = P2 ;
Sample assignment for both samples 1 and 2 into the different treatment groups should be randomized, that is a simple random sampling of subjects into the treatment and control group. The sample design for difference between two sample proportions should be independent.
Finally each of the two proportions P1 and P2 should record a minimum of 10 successes and 10 non - successful Occurrences.
Answer: B. perpendicular lines because they intersect at a right angle, making them perpendicular.
Answer:3
Step-by-step explanation:
Given:
A driver is below the surface of the water at - 15m. he dives down by 6m, then rises 4m.
To find:
The current location of the driver.
Solution:
In this problem, negative sign is used for downward direction or the distance below the surface of the water.
Initial location = -15 m
Dives down by 6m, it means - 6m, then rises 4m, it means 4 m.
Now, the current location is
Therefore, the correct location of the driver is at -17 m it means her is 17 m below the surface of the water.
Answer:
The answer is 0.25
Step-by-step explanation:
(1)we group like terms by subtracting 32.50 by 28.75
(2) we subtract 20 and 5 to give us a value of 15
(3)when we subtract 32.50 and 28.75 we get a value of 3.75
(4)so the equation will look like this 3.75t = 15
(5)we divide 3.75 we both the two equations
(6)With a correct calculation, Your answer should be t = 0.25
