Alright, lets get started.
Given that George is working in garden on each 3rd day.
Maria is working in garden on each 4th day.
Then they will not work together on days that are common multiples of 3 and 4.
The least common multiple of 3 and 4 is 12.
Means they will work together after 12 days from today. : Answer
Hope it will help :)
Okay...Can I have the rest of the question?
Answer:
The answer is -1.2
Step-by-step explanation:
Recalling the standard deviation formula,
we have : σ = sqrt[ P * ( 1 - P ) / n ]
Where sqrt = square root
n = Number of derivative
Therefore,:
if, H0: p is not 48% vs H1: p1 = 48%
standard deviation is:
σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+
z -score is (p-P)/σ
= (.51-.53)/.01666333
The answer therefore = -1.2
ICONCLUSION:
It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.
It is $100 because if you work it out on paper then you could have on the paper and the answer is 100$
X ≤ 19.2
