Answer:
And rounded up we have that n=1068
Step-by-step explanation:
For this case we have the following info given:
the margin of error desired
the level of confidence given
The margin of error for the proportion interval is given by this formula:
(a)
the critical value for 95% of confidence is 
We can use as estimator for the population of interest 
. And on this case we have that 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
So all you need to do is 7.35kg takeaway 2.6kg = 4.75kg
Mrs Warburton's bag now weighs 4.75kg
To find this answer, just divide 360 by 5 to find out how many times his heart beats in one minute instead of 5. Doing this will give you a final answer of 72 bpm.
Answer:
Step-by-step explanation:
1. There is a total of 16 outcomes
2. To get outcomes with a sum GREATER than 5, we have
2+4, 3+3, 3+4, 4+2, 4+3, 4+4 for a total of 6 outcomes.
3. To spin the same number twice, the possible outcomes are
1-1, 2-2, 3-3, 4-4 for a total of 4 outcomes.
