Answer:The correct option is a)
The upper limit of successes that would be deemed to be usual is 5, so more than 5 successes would be unusual.
Step-by-step explanation:
The mean of a binomial distribution
μ= np where n=10 and p= 0.2 q= 1-p, q= 1-0.2=0.8
μ= 10×0.2=2
σ=√npq
σ=√10×0.2×0.8=1.26
Is unusual for the number of success to be greater than μ + 2.5σ.
= 2+2.5(1.26)
=5 approximately.
So it is unusual for it to be greater than 0.5. The right option Is a)
There is no possible answer
22 + 24 = 46
24 + 26 = 50
We need to add like terms, meaning add the x's together and add the regular numbers together.
So if we add the x's together, -8x+9x = 1x.
Then when we add the numbers together, -12+4 = -8.
Combine our two sums and we get x-8 as the final answer.
Answer:
Step-by-step explanation:
We know sum of the interior angles of a quadrilateral is 
therefore we can write
so
So smallest interior angle is 
Largest interior angle 
(2.3*10^-3) / (4.6*10^-7)
(2.3*0.001) / (4.6*0.0000001) *10^-3=0.001 & 10^-7=0.0000001*
(0.0023) / (0.00000046) *2.3*0.001=0.0023 & 4.6*0.0000001=0.00000046*
5000 *0.0023/0.00000046*
So the answer is 5000
