D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
Answer:
The answer is 0.25
Step-by-step explanation:
This is a binomial distribution question, since it is equally likely probability of success (p) is 0.5 and the probability of failure (q) is 0.5.
Using binomial distribution formula
P(x) = n CX PX qn-x where C means combination
X =3 , n= 4
P(x) = 4c3 × (0.5) raise to power 3 ×(0.5) raise to power 1
P(x) = 4× 1/8 × 1/2
P(x)= 0.25
Answer:
<em>The 90% confidence interval for the population mean length of nails produced by the machine.</em>
<em>(2.91562, 3.04438)</em>
Step-by-step explanation:
<u><em>Step:1</em></u>
Given that the size of the sample 'n' = 10
Given that the mean of the sample (x⁻) = 2.98
Given that the standard deviation of the sample (s) = 0.09
Degrees of freedom = n-1 = 10 -1 = 9
t₀.₁₀ = 2.2621
<u><em>Step:2</em></u>
<em>The 90% confidence interval for the population mean length of nails produced by the machine.</em>


(2.98 - 0.06438 , 2.98 + 0.06438)
(2.91562 , 3.04438)
<u><em>Final answer:-</em></u>
<em>The 90% confidence interval for the population mean length of nails produced by the machine.</em>
<em>(2.91562, 3.04438)</em>
Answer:
Suppose the number is 4
Square of this number (4 x 4 ) = 16
Divided by 2 = 16/2 = 8
Added to 16 = 8+16 = 24
